I'm trying to optimize my Ryzen 9 5900X CPU cores with AMD Ryzen Master Curve Optimezer but it doesn't work. How to access Curve Optimizer feature in Ryzen Master? A dedicated profile is provided for this feature named as "Curve Optimizer"€ Is it supported on all AMD CPUs? Hello everyone! The AMD APU Tuning Utility team have recently released a build of AATU (found here) that allows the manipulation of the V/F curve for 5900HX CPUs, in a similar fashion to the desktop 5000-Series Curve Optimizer (0 to -30 max limit). As a good precaution i would suggest running the full 6m per core test at least few iterations to make sure everything is actually long term stable so you wont crash later mid Set my curve optimizer to -18 -18 -18 -20 -25 -25 +200 on +MHz Get around 11900-12000 on r23 at 77 degrees No errors or random restarts. ive been running -30 curve optimizer since the day i bought it (last 2 weeks ago) been playing warzone, left the pc on for 2 days because i was downloading games (on a 10mbs internet, its free intertnet in my apartment) seems to be stable, i never had a blue screen or random restart. If not I suggest to Reset Profile and not use the "Auto Optimization" as other users have also reported it does not seem to work correctly. It applyes, bot nothing changes, even on -50mV. 3, no matter if I put the negative offset -Reverted all bios settings back to standard/auto and did not mess with PBO/Curve Optimizer-Purchased new AIO Your system is working as it should be with perfect low temperatures. It's not about the hardware in your rig, but the software in your heart! Join us in celebrating and promoting tech, knowledge, and the best gaming, study, and work platform there exists. Reply reply Arx07est • • wow thanks, curve optimizer does well. optimize package to fit a set of simulated data to find the curie temperature of CoFeB. I tried to put one core at +0 and all other cores at -30 in order to see a This is because curve optimizer is applying a static offset to the final voltage the cpu runs on. The fitting procedure will try to take small steps (typically around machine precision) in the parameters to get a numerical derivative of the residual with respect to the variables (the Jacobian). I read we need to test how the CPU works at low/light loads and idle as well. B550 phantom itx - curve optimizer per core option not showing cores I just noticed that the auto curve optimizer completion time is affected by the 'stress time' value in the settings page. I guess I shall find out soon! 14 Mar 2021 at 10:44 #11 LtMatt. curve_fit to fit the data, and I have more than 10000 data sets to fit, so I used a for loop to run curve_fit for 10000 times. I'm currently working on optimising my Curve and stability testing using Corecycler (it's awesome and the only I've tried to set my Curve Optimizer in Precision Boost overdrive under Extreme Tweaking/Precision boost overdrive. Download Ry The 5800X3D doesn't officially support PBO or curve optimizer. 75ghz MT during cinebench R20 runs. LtMatt. setting the same curve optimizer value to all cores is a bad idea, most likely it will cause instabilities/crashes in the future. But I would play with Curve optimizer, its not really an overclock, It just changes where to apply more voltage at a If it even crashes once it’s still not good, warzone or Cold War is utter shit coded since everything else works. I'm trying to fiddle with the CPU Curve Optimizer but I noticed that whatever the values I set, it looks like it's not applied at all. Reply reply The on 1. DANGER! Further reducing the Curve Optimizer to -35 did not result in additional frequency, however it did reduce the voltage by 7 mV. I'm currently at 1 week of PBO2, Curve Optimizer and light/load testing. Mine seems to be pretty strong and my weakest core was still able to go negative 18. The setting were: -15 to -24 co X10 scalar +75mhz 150/95/148 power limits I started researching curve optimizer threads again. I’ve started at offset of 30, but it crashed while logging to Windows. Not sure if that's good for a virtual machine or not. I suspect this is due to the data set values being very small Ryzen Curve Optimizer works by analyzing the voltage-frequency curve of your CPU and making adjustments to optimize performance. (Not sure but I guess they did with 1. Chaotic_Sandwich: Is there a hidden BIOS menu for overclocking Just got my FW16 DIY with a 7940HS but cant find any way to access the curve optimizer or change ram speeds (currently ram is stuck at 4800) Is It's not hype. 3x0. I flashed previous version now and there's no Curve Optimizer. Reply reply spheexx12 Over the last couple of days resp. I'm a bit confused because two of the key settings (I think) seem to be contradictory, being the curve optimizer offset (from 0 to negative 30) or the manual OC boost limit (from 0 to +200 mhz). -Reinstalled Try switching Ryzen Master language to English in settings. The best cores don't go as low as other cores for some reason. My 5800X3D was very picky and took a lot of work to really dial-in, whereas this CPU has not been picky at all so far. Hello, I have an x670e-F with a 7700x, running on the latest public UEFI (2007 right now). This is why you see recommendations like set your best cores to X and all others to Y. Therefore, while fitting exponential functions with exponents depending on time stamps, the best is to adjust the time exponent by excluding the time of the first data point, changing it from:. It's legit. Warzone no whea errors or crashes. Single core stayed the same though out stock, 105 and 125 watt eco mode. Hello! I'm having trouble Curve Optimizer feature in Ryzen Master. I then ran Ryzen Master's curve optimizer at the "per core" setting and let it finish over the course of ~70 minutes. I know we all dislike userbenchmarks, but I was able to get a 100th percentile score compared to other Also few tweaks to make this faster. Adjusting all cores does work and have a measurable effect but now i wanna go deeper in the topic and set up a "per core" setting. Can’t help with the CPU, maybe Universal X86 Tuning Utility could work on the FW16? 1 Like. Reactions: 3x0. I only really touched the Curve Optimizer section. I shared the official info from AMD with you, it doesn't get more official than that. It sets too high I'm trying to optimize my Ryzen 9 5900X CPU cores with AMD Ryzen Master Curve Optimezer but it doesn't work. Roland Of Gilead Titan. It shifts the actual voltage and temperature curve of the CPU/core down. Yes, that can give performance increase since it means sustaining higher clocks for longer, but it won't actually increase clock speeds itself. Each core has multiple V/F curves that vary depending on load on the CPU. My CPU's best cores are Core 0 and 1 in CCD 0, Core 6 and 8 in CCD 1. Tested Curve optimizer at -10, -15, -20, -25. 8. I had to use -20 all core in curve optimizer to be able to boot. With method='lm', the algorithm uses the Levenberg-Marquardt algorithm through leastsq. My idea was that it would be really cool to manage this curve, not like an offset but more like: "Go -20 when at Curve Optimizer All Cores Negative 20 Max CPU Boost Clock Override - 0MHz Platform Thermal Throttle Limit - Auto I just followed other users guides to know what to do. Note - Ryzen Master was running in the background for Curve Optimization is very easy - the testing being automated - and poses no danger whatsoever to one’s hardware; the worst you can expect is a Windows bluescreen, and that is no more deleterious than stalling a car. Scipy optimization curve fit not working properly. How can i switch ryzen master to english on german windows 11 ? I use default values -30 to create the curve and no crash reboot during curve optimaze h I've been trying to fit a function to some data for a while using scipy. 0. Soldato. So they just disabled Curve optimizer only works if you get a good cpu, if you lose the lottery your system will just crash when you try CO . So far very stable Also i was interested in the eco-mode to switch to when i'm doing light work. With 8 cores its much easier to do a per core curve optimizer. Discussion Hello everyone before i mess with the settings i read and try to understand how everything works. Super lucky? Here’s my strategy to making Curve Optimizer somewhat useful: Manage to get it to complete (the hard part) Take down the optimizer values on my phone or a notepad Anything with an offset over 10, reduce the offset by 33%. I read the guide from katalysis (Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. It works . I hope you understand that I cant validate that till I have a chance to personally try on a 7x00X3D. By offsettting the curve youre lowering the voltage for the curve, resulting in less heat as long as its stable. When optimizing ALL cores, the computer turns off and on instead of rebooting. It just doesnt affect scores further. @Wickedtt mentioned here that Curve Optimizer first appeared with AGESA 1. I know that it works for others, but certainly not for everyone. If you leave it at "OFF" and perform optimization it just returns settings to defaults, No Optimization. I've got a mediocre chip, but it turns out not clock stretching is the best possible outcome instead of getting a few more mhz in a single thread. Since then I’ve run into some odd behavior on my installed system which I won’t go into specifics, I tried looking into them but couldn’t find anything of use, until I started suspecting hardware It's not included in some motherboards but I bet it's due to justing manufacturers being lazy. Than you must lower the PPT TDC EDC as much as you can without loosing performance while lowering the temps. It will take a while to go, but you'll end up with values in the CO All Core Value and Difference Offset Value. From Zen1 (Ryzen 2000 series) to Zen3+ (Ryzen 6000 series), please join us in discussing the future of mobile computing. Curve Optimizer is a All brands/500 series (not sure about 400) motherboards should have Curve Optimizer I think since AMD added it with the latest AGESA. I could go more negative on my stronger cores but it didn't make much of a difference in my testing so I didn't spend the time to find the exact limit for individual offset. Attention! By: u/DragonMaster9595 - the curve optimizer settings can only be used by renior apus, and ryzen 9 hs or hx czn and rmb apus. At the time I was just using curve optimizer and a gpu uv, however I improved my setup with the following settings; custom per core curve optimizer through ryzenadj (median about -20), sppt to 110w, in umaf bios no cppc preferred cores, scalar to x1 and custom dram timings at 3600 c20. my guess is due to small amounts of 7950x3d being sold these The rig runs hot as hell, even with the noctua heat sink + intake fan I added so I tried to undervolt it in the BIOS but there’s no curve optimizer prompt. X570 tuf 3001 bios My final settings are still work in progress Update: I have settled for -20 on the top 3 cores and -10 the worst 3. From what I can browse, overclockers forum, redit, and all that. Hitting "Apply" I'm having trouble Curve Optimizer feature in Ryzen Master. In comparison, my 7600 and 7950X could work at -40/-50 (I don't remember which was -50). Elmor also mentioned a little about Setting a positive 200 to PBO max boost clock increase and a -27 to the curve optimizer, I was able to increase the max single core clock speed to 5850Hz and the max multi core full load clock speed to 5500Hz. I tried PBO auto per core Curve Optimizer on my 7950X and it got around 2/3 of the way complete but then it crashed the system, rebooted, started it up again and it crashed again a bit later and when I started Ryzen Master up again the second time it didn't continue the process and I was back to square one again - no messages about the process it was running or anything. The utility uses advanced algorithms to identify the optimal voltage and frequency settings for your specific CPU, taking into account factors such as temperature, power consumption, and system load. 12 and I = 2. I kept on switching between Off, per and all core but none gave me good results, or not as good as manual settings in BIOS. Hope you can get yours to work! If I understand correctly, Start Optimizing is intended to automatically try and find the best offset to use, and Validate Offset is to test the current offset. If you have one of these boards, it doesn't surprise me at all that curve optimizer and/or PBO would "work" in the BIOS but would still not be available via AMD's official Ryzen With the recent release of AATU's Curve Optimizer offset tool, I decided to spend some time doing an analysis on the relationship between power draw, thermals, and performance, at some arbitrary curve optimizer offset steps. OP Joined 12 Jul 2007 Posts MSI Afterburner fan curve not working Build Help Background: I'm running a Rog Strix RTX 3080 OC, undervolted. zerijelly Well-known member. I run -30 all core on With this script you can test the stability for each core, which helps you to validate if your Ryzen "PBO" resp. Anything over 20, halve it. 3. I'm 95% sure I found my chips limit, and light load has been stable over 24h of various core testing. 2 agensa from asus, my 5900x running fine with curve optimizer and 4000/2000 cl16 timings. This went all great when I tried to generate a curve with the curve_fit example but not when I use my own data. After reviewing some co boosting data at low and high frequency, I saw that the low freq undervolt was more significant (vs stock) than the The best rated cores will often times do most of the highest frequency work and as the overall workload increases and the overall clocks come down the worse cores will get loaded on to. Even though this guide is aimed at everyone, I am expecting you to at least know some of the basics about how ZEN cpus work, this includes PBO, PBO limits, navigating BIOS, troubleshooting potential issues that arise, etc. Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0. Apply the changes in BIOS and not RM. On the other hand, this CPU runs almost the same if there is a curve optimizer enabled or disabled. it is german text. Is PBO2 + curve optimizer available feature in A520? ~~~~~ Edit: (Solved) After receiving my parts, here is my findings, You can turn on PBO and set power limits, PBO scalar and curve optimizer on a520 boards, specifically Gigabyte A520i AC. G-Helper undervolting didn't work too, logs says that just "FAILED", (so I don't know what caused this). net forums. Also the ability to undervolt is separate from the ability to overclock. AMD ZEN 3 PBO & CURVE OPTIMIZER OVERCLOCKING GUIDE. 3 not working correctly. Steps I have done to remedy this: -Removed riser cable and reinstalled GPU normally. I just used Ryzen Master to activate PBO (no manual changes) and curve optimizer set to -20 all core. and sorry for my bad English. Fingers crossed the CTR 2. Take a look at task manager and identify applications that are preventing idle. They just not appear. You can try with PBO2 Tuner from PJVol over at overclock . Yes, PBO is considered overclocking. I lost 10c not only in all core cinebench but also in cyberpunk and new world. Default is 30s. . Then i enter valeus above in curve optimizer and i had a boot loop (automatic repair). B620s can only use XMP/EXPO and does not have access to other OC settings. com)) and was very confident that I had learned about the somewhat unusual test of forcing "Windows 10 Automatic Repair and Diagnosis" for ten times. 1 auto curve optimizer feature takes a lot of the work out of Curve optimizer works exactly the same way on X3D and non-X3D. curve_fit(): it is (silently) very particular about the dtype of the x and y data. The Personal Computer. Notes. Latest: Shahmatt; 2 minutes ago; PBO limits disabled and All cores curve optimizer set to Negative (X570 Tomahawk WiFi, latest BIOS). -5 all core otherwise I’ll get lockups in idle situations yet at load it works perfect. I am currently running a Legion 7 Gen 6 when i create the curve per core i can choose per core and reboot. 1ghZ and -30 on curve optimizer. Benchmark was doing 15 laps around my raft. curve_fit producing nonsensical curve fits. Open the Core Cycler config at change the run time to 2m at first and do the changes to curve optimizer values after first iteration. 2. At this point the CPU is very close to the thermal limit as it reaches close to 100°C Welcome to the Ender 3 community, a specialized subreddit for all users of the Ender 3 3D printer. I never used either of those options, and I've seen others report they don't work correctly anyway. scipy. CJ_Elevated February 29, 2024, 1:06am 3. the setting is per core but mode on left side show all cores. Example: Browse If i select auto for curve optimizer , it keeps working. I had check all of it, any options, no way to undervolt my R7735HS. # encoding: utf-8 from __future__ import (print_function, Good luck and will be appreciated if you'll post here whether you'll succeed in tuning using curve editor or if you at least will see it after installing the latest version. If you are not really the kind of person who REALLY likes to fiddle around and reinstalling your OS a lot (because you corrupt your OS files from reboots), you should leave Curve optimizer alone and just set your TDC / EDC at your "max tune the AVFS curve of the entire CPU or specific cores of the CPU such that the tuning overrides the fixed curves that they are fused with, resulting in an increased CPU performance. Members Online. Finally I set the curve optimizer to -10 all core, and behold, I get around 620 SC annd 8700 MC. Joined 19 Apr 2012 Posts 5,306. Only B650 motherboards Try a setting of -15 all core and test for stability, -30 allcore is fine for some cpu's but it can freeze the system when it's idle. 0. CO is better than PBO at getting higher clock speeds in gaming. It should even work on int data. What I've found is that curve optimiser was stable under very high load tests, but games that only used a few threads would crash. This won't increase single core performance much but my R20 multicore score reaches 6250(5800+ stock) If you need stable with high single core performance just do not use curve optimizer. So you ideally need a curve that works in multi and single load scenarios. Curve optimizer . As I remember, it works with a curve optimizer at -20. this has something to do with 0 and 1 being preferred cores so they tend to boost higher already in lightly threaded work loads. When the 5800X3D was released, no motherboards had PBO or curve optimizer as an option with this CPU. I’ve kept testing and so far managed to go down to 13. bat" file. Try to identify the best cores with Ryzen Master and start pushing the good cores up. The following guide should work for the following CPUs: Ryzen 9 5950x; Ryzen 9 5900x; Ryzen 7 5800x; Ryzen 5 5600x; The following should similarly work for Ryzen 3000 series, but you will not have access to the Curve Optimizer. 0, using curve optimizer does not seem to be changing my power draw at all. 0) : Amd (reddit. Basically, a 50mV undervolt tells a CPU that instead of operating at, say, On a new PC build and fresh installation of Windows 11, with all BIOS settings at default except for the RAM profile set to EXPO, my system was running normally. These tend to create instability while using the curve optimizer. When a core is under load, it gives it extra voltage. They didnt want to bother to disable most overclocking options and include the supported ones on x3D. Any help is much apprecaciated. When I resetted cmos 8 core curve optimizer came. Caporegime. I tried to determine my best cores at first but the curve optimizer didn't work that way. Skill Flare X5 6000CL36 64GB (4x16GB) / Curve Optimizer - per core, -25,-25,-25,-20,-15-15 Max Boost Clock Override - 200 MHz Thermal Throttle Limit - Auto Mine is not great either. - I'm not sure if Prime95 is good to test this curve optimizer. When I started PC with 5800x and loaded 5600x profile curve optimizer showed 6 cores only. But to say it's useless, or more specifically, "hype", is not true. GN is not infallible. First, the testing environment and equipment: Legion 7 Gen 6, Repasted with PTM7950, with a Ryzen 9 5900HX Ambient temperature was 22. Benchmark numbers are in order: average fps, 1% lows, 0. This is still a bit shy from the advertised 631 SC, so I decided to decrease the curve optimizer in increments of 5 until Cinebench crashes, and then increase it by 5. The 5600x in my new A520 board goes to 4. 8°C, or 73°F I recently had to soften my CO curves a little bit after configuring CoreCycler to work with 720k-720k block size. Motherboard X570S UD Ryzen 9 We're testing on a Ryzen 7 5800X purchased at retail with an ASUS TUF Gaming X570 Plus Wi-Fi, 32 GB of Corsair DDR4-3600 CL16 memory, and a GeForce RTX 3070 Founder's Edition. In particular, there's no good reason for curve_fit to fail on float32 but succeed on float64 data. But there is also a Curve Optimizer in Precision Boost overdrive under the advanced/amd settings How do I know it's working, what should I Another problem to watch out for with scipy. curve_fit but I have real difficulty. It also works to test Intel's "Active-Core" Turbo-Boost settings. set a -0. Reply reply This curve optimizer is awesome. But if it's behaving mysteriously for you, try coercing your data to float64. The function (curie_func in the code below) should work and I have tested plotting it with realistic values as initial parameters (p0) to demonstrate it fitting well. Ryzen 8600G should support per-core curve optimization, verify compatibility with AMD or reinstall Ryzen Master. Uninstall Ryzen master and made a clear cmos. This is my first AMD and most annoying pc build ever -_- After I had been working with the Curve Optimizer for some time. Manual Overclocking. 1 and 5. Max boost clock override (AutoOC) +200 MHz I have a Dark Rock 4 cooling my CPU along with good case airflow and this works great for me. But if it works better or not depends on many factors: ram density, MB, bios, agesa version, luck, ecc Sometimes works best with the automatic all equal, sometimes it's best with little gaps, and some other times you can also use very large gaps like I Seems like my AsRock board lets me go well past -30 on the curve optimizer. That's not exactly what curve optimizer does. Forums. very impressive, just wish it would "Do what makes the experience better" - in regards to PCs and Life itself. Anecdotal evidence suggests that this DOES NOT WORK with 5800H/5600H. -5 on curve optimizer doesn't even work. Any more than -15 on your preferred cores will cut On a new PC build and fresh installation of Windows 11, with all BIOS settings at default except for the RAM profile set to EXPO, my system was running normally. Hello I have a 5600x with pbo and auto oc (+200) active. The previous BIOS version comes with AGESA 1.

Thanks to this video:Disable c-states for better curve optimizer settings on Ryzen 5000 zen 3 PBO - YouTube You need to disable "Global C-States" and "DF C-States" in the BIOS. Will Have to do that test again. There is even presets for -40 in the overclocking section. Reply reply Wint3rmu7e Wasn’t aware that there was an auto curve optimizer until now. 1% lows. 13 Mar 2021 at 20:57 #10 michty_me. 1 but then I had kernel not found or corrupted bsod. But 7th and 8th cores were zero. But i never used the ryzen master app except to check on temperatures and frequency . Upvote 0 Downvote. I have tried in ryzen master, as well as the BIOS, during r23 multicore, it seems to pull between 220 and 230w according to Core Temp, and boost between 5. 5800x ROG STRIX B550-F GAMING 1401 is working great so far. But at that point you Don't enable vcore dynamic offset while using curve optimizer and disable the boost and scalar completely. michty_me. Curve Optimizer results can vary between individual CPUs due to the “silicon lottery. Every real work cycle increases the performance counter & wait cycle / not working cycle decrease the performance counter. This thing passes Aida64 Extreme running for hours and Cinebench R23 for looping for long periods of time. I go to Advanced —> AMD overclocking—-> accept ——Percision Boost Overdrive—-> advanced. If you really want to get out everything, curve optimizer is weeks or even months of work for +/- 100-200 mhz. Works in laptops, monoblocks and desktops. I just want my rig to run cooler. I know not many are running VMs, but i would be curious what anyone else is getting in a VM. I then ran I experienced the same thing, the app wasting hours and giving an all core -30 result, which is completely unstable when set from the BIOS. I really can't see any reason why this wouldn't work. Setting max boost override to +200 MHz (which gets others up to 5 GHz However, scipy optimize curve fit is not giving me the values I want, which is where n = ~1. The Curve Optimizer lets you tune the VF-curve per core or all cores in BIOS Of course it should be updated in the next couple days with other goodies from AMD,but as of now for stability it works awesome and you get great single core/multi performance. As for temps, you need to set lower power limits in addition to setting curve optimizer, to get the biggest temp reduction. However, even that might not be true on a single sample and so copying someone else's recommended settings is probably not going to work well. For instance, my 5800X's 2nd best core is unstable if I set it to below -3 (-4,-5,-6,and so on) while the others can be set lower than -10 (some of them can reach -30 with no issues). Skill RipJaws S5 DDR5-6400 @ DDR5-6000 / 1,3V Thermalright Phantom Spirit SE 120 Results I have a new build consisting of a 7950x, and x670 gigabyte aorus elite ax rev 1.

I have negative 10 on cores 0-4 and negative 35 on cores 5-11. Going to -30 was mildly unstable. When I booted into windows 6 core curve settings were the same with bios. Works for intel 4 series and up and amd zen series and up. Onyx: A MD Ryzen 7 7800x3d / ASRock Taichi 7900xtx OC / Gigabyte B650 AORUS Pro AX / G. For many years i used Ive had a working and stable co set up on my 5800x for quite some time. weeks I've been working with the Curve Optimizer for Ryzen processors a bit more, but I hadn't found a good way to test the settings for stability. BIOS Settings Curve Optimizer will tweak the voltage/frequency curve so that the processor can run at a higher frequency at the same voltage. 2 and . Here, enthusiasts, hobbyists, and professionals gather to discuss, troubleshoot, and explore everything related to 3D printing with the Ender 3. Through manual overclocking the limit was found to be around 4650 MHz with 1. Ryzen 5000 – Traditional overclocking is dead Curve Optimizer is a great way to squeeze a little extra performance out of your 5000 series CPU, but it does take some patience to master!AMD recently relea Some motherboard don't have Curve Optimizer or PBO control for 5800X3D since OCing the 5800X3D wasn't officially supported when it released. However, decreasing the curve optimizer to -30 decreases the max single core to 5600Hz and max full multi core to 5400Hz. im on -30 on all cores working without any issues Hey all! I previously posted about my recently built machine being unable to sleep properly on Linux due to issues with EXPO, I’ve disabled it and it appears to work properly. How can i switch ryzen master to english on german windows 11 ? I use default values -30 to create the curve and no crash reboot during curve optimaze h i'm trying to do undervolting 5800x3d with pbo2 but it's not working at all i tried from -5 to -50 but nothing idle is 43 under load is 90 cb r23 i did Menu. When it said it needed a restart, I pressed yes and now I can't even get to windows at all. Curve optimizer shifts the graph plotting f(x) =y Large negative exponents make the exponential function close to zero, thus making the least squares algorithm insensitive to your fitting parameters. Selecting per core in bios does not show the section for adjusting CO and polarity for each core. Let’s illustrate so I set +50Mhz Boost Clock Override and -25 Curve Optimizer all core. AutoOC is the same as Boost Override and it was in the original PBO, now in PBO2. 95V instead, and whatever frequency is mapped to 1V is now >2GHz. Here is my raw data: https://pasteb I have tried using the curve_fit function from the scipy. However, what I have tried is not fitting the data. That particular size kept finding issues with several cores that had passed the default Core Cycler size profile settings just fine, and had been running fine for months. To put it succinctly: Curve Optimizer overclocks your CPU. However, curve_fit only worked successfully for the first 49 iterations, and after that curve_fit stopped working--to be more specific, the curve_fit function did not return anything, and I've been toying with my new 5900x chip, and have been reading up on the new PBO2 and curve optimizer tool. I only have a Validate Offset option. When you add those two values together, they give you your PBO offset. HOW? ---- Double click the "Run CoreCycler. Key Takeaways. Difference is small but it is there A community dedicated toward all things AMD mobile. "Curve Optimizer" settings are actually stable. Though I noticed my fan curve on MSI Afterburner is not working at all: https Ryzen Master Curve Optimizer, how to know it's really applied? self. When I look online, guys advertise a curve optimizer at -30 (or more) without flinching and without doing anything special. 15ghZ but that didn't work so I tried going back to 5. My 5600x only runs at 4450 when fully loaded with a CPU burner, system is The curve optimizer its like I said, its not a statement from my end. The unofficial but officially recognized Reddit community discussing the latest LinusTechTips, TechQuickie and other LinusMediaGroup content And I tested what the person did on the video and it's impressive how the temps lowers very significantly while keeping the cores working as normally would, so at least under some kind of load the system seemed stable at -30 on all cores in curve optimizer, didn't got to test on idle yet so as you guys said that might be the trick to test, also 7900x Curve Optimizer per Core Help Request - CPU Hello All, TLDR: My 7900x is stable (at least from 24 hours of torture testing and ovber 48 hours of normal usage) with a -30 Offset per Core. optimize. 1. 1% can be ignored as it's too short benchmark to get enough frames to have accurate data Curve Optimizer not working at all on B550i Pro Ax? Hey, I'm on F13 BIOS on my B550i Pro Ax and trying to use Curve Optimizer but I see absolutely no difference between it being on and off. Home. It would blue screen and then I'll try to restart again, and try to get in the bios but still wouldn't let me. You can try it but also try not doing that. -Cleared CMOS. Go to Advanced View, Curve Optimizer on the side, then set Curve Optimizer Control to All Cores and then click Start Optimizing. I tested offsets manually starting at All Core at -30 and ran Cinebench to validate. I was wondering if there is a way to confirm that a negative curve optimizer offset is stable without performing a long test that will take a lot of time and use a lot of electricity. EXCEPTION OF CHECKING THE MACHINE. It seems like it only fits the first parameter. I set it manually to different negative values and I don't see any difference. 30 works as it was a bust in a 5800X3D. Right after I tried going to 5. Temps are 95 stock 70c 125watt eco mode and 60c for 105 watt eco mode. Even Smokeless UMAF just not shows up whole AMD CBS menu. Edit: Real world example. Blame AMD for this. 8E-13, and is instead giving me n = 2. Horizon Forbidden West coming to PC on March 21st Hello friends Faced such a problem. But the devil is in the details because AMD’s Precision Boost 2 technology doesn’t really work with V/F points. Incorrect adjustments can lead to system instability. Reply reply Heard that. Note I experienced a similar thing when I switched from 5600x to 5800x (not 3d one). Positive offset would let the CPU use more voltage to achieve higher clock speeds if they weren't possible with a lower voltage (theoretically, and only if the thermal and Started to play around with PBO. If you want lower temperatures then lower your pbo limits or enable Eco mode, some Ryzen master won't show curve optimizer. And if it turns off and on for the first time, then when you reboot, the op So I just installed ryzen master today and used the curve optimizer. The Ryzen Curve Optimizer enables individualized voltage-frequency tuning. Max is 100. This is apparently a common instability condition for Ryzen when undervolting, Part of me almost wonders if Curve Optimizer is working correctly, since it seems almost too good to be true. Then i I'm trying to fiddle with the CPU Curve Optimizer but I noticed that whatever the values I set, it looks like it's not applied at all. Ive run both the curve optimizer on Ryzen Master and the optimizer on the HYDRA software and they both set all my cores to a -30 offset, how reliable is this? Ive not had any issues gaming, running benchmarks etc. the 5000 series boost algorithms favour lower temps, so lower temp can equal higher boost freq, at the very least higher sustained boost. Results From Curve_Fit Are Off. You'd want to increase it until it's fully stable under all thread-load conditions. At idle or moderate load the voltage is lower - sometimes too low with aggressive curve optimizer negative offsets. because power is not the limiting factor in your gaming clock speeds. Curve I wanted to use scipy. In the end you get an estimate number. I wasn't sure what exactly the Scalar did, so I left it on auto. ” AMD provides automatic Curve Optimizer settings, but manual adjustments might provide even better results. 26-26-26-24-26-26. Is it applying a static offset to the voltage delivered to the CPU or is applied to the final voltage delivered to the CCXs/CCDs/individual cores? I'm not trying to be an ass, I haven't had an opportunity to play with this feature yet. essentially more efficient, which youd possibly see more frames in gaming but alot of it depends on your cooling as well. After it finished First image is stock and second is with my +200MHz curve optimizer undervolt and with the same stock limits. It actually finished Cinebench R20 with 25 offset, but would crash instantly in Doom Eternal. Z. Ryzen 7 7800X3D B650 GAMING X AX V2 G. optimize) assume that parameters are continuous variables, not discrete. 1v offset and a high boost clock override. during normal work, etc = during short bursts (with not enough cooling headroom). The issue is that I am not presented with a Start Optimizing button. This is a beginner's guide updated with the latest techniques. Thanks! I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be able to have lower negative offset than the other ones. 4. 15 and Io = ~1. Or Keep in mind curve optimizer you WILL need to find what works for your chip. if you are prepared to leave it running overnight and/or while at work, though, this is not a problem – and it can take a How to overclock using Ryzen Master and the new Windows feature - Curve Optimizer. D. Stable in Doom after Scipy optimization curve fit not working properly. CPU is so strong even with 5200 RAM (also with 4800 MHz) it runs very efficient and powerful PBO 2. Cinebench r23 multicore: Stock = 15333 88c, -10 = 15640 88c, -15 = 15444 90c, -20 = 15803 83c, -25 = 16028 83c -20 seems to being doing great so far. If it is caused by iCue, contact Corsiar and create service ticket for iCue Now need to tune Curve Optimizer to the max stable, add boost and balance clocks to prevent clock stretching. You can see obvious improvement. Maybe yes, but maybe with lower ppt ( so you force all cores in lower freq and voltage). I've lost about 1200 points in CinebenchR23, it used scipy's curve_fit (and all other optimization routines in scipy. Now CO is stable again at -23 across all cores in my 5900X and is spewing the same performance numbers as in WIn10. So short answer: Hey, I just wanted to share a quick overview over the results I got, with like no effort at all. f = exp(-x*t) The link is timestamped but if it isn't working, it's pretty much only the last sentence at the end. 0 Patch B or C). If you want more performance out of your cpu with curve optimizer then you can use this guide for it. But so far my settings are: Just got my 7800x3d up and running and have been working through optimizing bios settings and it's, interesting. You need to go into the BIOS and disable Curve Optimization in order for Windows to start. Users should ensure that inputs xdata, ydata, and the output of f are float64, or else the optimization may return incorrect results. So, instead of getting a list of specific tunable V/F points, we get five regions and three temperatures: That means we can combine Curve Optimizer and Curve Shaper to finetune the voltage-frequency curve. 11E-11. The one on right side is just to perform chosen optimization and does nothing until you actually perform it. Using the Asus Rog strix x670e-e gaming , 7800x3d It freezes in Adrenalin, keeps working in hardware monitor. Follow up: I decided to lower the values in Curve Optimizer. The same curve optimizer settings wont work for everyone, especially if you do all core. Auto curve optimizer is not reliable. Amd It's easier to first find a stable all core curve optimizer and then go from there, i started from -10 all core. Hot Network Questions How bright is the sun now, as seen from Voyager? -Reverted all bios settings back to standard/auto and did not mess with PBO/Curve Optimizer-Purchased new AIO Your system is working as it should be with perfect low temperatures. Joined Please, people, dont play with PBO and curve optimizer on 7950x3d. demi9o154902d9 New member. FIRST LIEUTENANT. 18/day) System Specs. All of the things we're discussing fall under PBO and PBO2. If i'm testing let's say core 1 with -14 and passed my stability test I would add 2 steps, meaning -16 and test again, if -16 is unstable just go back to PBO 2. optimize_curvefit gives bad results. Take a step back and first understand which are the relevant bios settings. Curve optimiser gives better Turbo boost multipliers at multicore tasks by downvolting CPU curve, afaik. Processor: AMD Ryzen 7 5800X3D UXTU Curve Optimizer didn't work. For brief background tasks or destiny the working thread is Set Curve Optimizer to -25 on all cores - how stable this will be is entirely dependent on silicon lottery, but -25 on all cores is 100% stable for me. 8ghz ST and 4. I run ryzen master auto tuning per core curve optimizer and come came up with negative values. So I tested my previously determined CO values and I'm not doing all core myself as I couldn't go as low as I wanted to do in doing per core. If it is caused by iCue, contact Corsiar and create service ticket for iCue I'm working on memory OC now that I've rid myself of the majority of cache throttling through better optimizing the CO curve Once that's "complete" I'll likely move on to using Hydra Pro to further refine the curve from within the Really glad people are working on core curve optimizers. 9. The nature of how curve optimizer works means that you are more likely to have instability when your system is idle than at full load (even when testing only one core). 29 V actual voltage during load. It first found core 2 giving errors, but it The offset on PBO refers to the voltage that the CPU asks for. It works. CineBench single threaded almost always I have a 7600x. I have two of my cores boosting to 4820mhz constantly for long durations on my 5600x (previously maxed out at 4640 mhz boost). Hello guys I tried using the curve optimizer now the first time I got it to work all cores 5. Reactions: 10578. I Hi there guys, just an small post to gather some curve optimizer negative offsets on your AMD Ryzen 5000 series. If even a single core doesnt like -30 it will crash, either do a lower all core or tweak per core. If you want to overclock it, then check higher blck and lower voltages at the same time to keep it I’ve also tried 105 watt eco mode with 33000in multi core without curve optimizer and 35000 with curve optimizer. Testing to see how well it works but the estimated time start to finish is a little over an hour 😐 For anyone who has not tried or is skeptical, this utility works, at least for me it has produced measurable results. Curve Optimizer values for the best cores are -12 and the rest are at -20. The other option is to go into the motherboard BIOS and clear any Curve Optimizer settings there. I tried to put one core at +0 and all other cores at I had reduce my curve optimizer negative offset from 28 to 26 after two system crashes confirmed that my 5900X was not stable at low load levels. You just have to love PCs. The higher frequency is directly a result of a lower voltage (heat). How do i get the curve_fit to fit the data? Hot Network Questions Can doctors administer an experimental treatment without patient consent in Right, exactly. I'm not sure what I'm missing or setting wrong, unless my CPU is really bad. There is no Curve optimizer option listed. My setup: Ryzen 7 7800X3D AsRock B650M Pro RS 2x24GB G. Join us in celebrating and promoting tech, knowledge, and the best gaming, study, and work platform there exists. Aug 8, 2008 11,557 2,777 80,240. New posts. Question HDMI does not work: 2200G + AsRock B450. Reply reply lexsanders • Idk why you would say that, it's not correct. If you were to cool the CPU with chilled water (-5C or so), you would probably see lower temperatures from tweaking curve optimizer. Radeon drivers 23. Skill Flare X5 Series 32GB DDR5-6000 I don't think tuning curve optimizer on a single core basis is a great method for finding a stable curve.
