With the key feature being per core undervolting, I'm personally finding that just leaving all cores with a -30 offset is yielding the best results for my chip. Before you start venturing down the path of lowering temperatures for the sake of having low temp, you should realize PBO2 is pretty aggressive and will throttle performance based on temperature. Guys, I'm redoing my CO with PBO2 and just let OCCT run for 2h on each core alone. But i read that with PBO2 the performance can be better also if on cinebench i lose 1 % That seems pretty close. Testing needs to include standard stuff like Cinebench and you need to check each core individually using CoreCycler. Temps are fine, 73-4 under C23 run on Arctic Liquid Freezer 420. 4Ghz even with the extra voltage applied. Clocks are only during benchmarking. Link to comment Share on other sites.

Reply reply Hey, I 'm using ryzen 9 5900x. 5ghz with Dark Rock Pro 4 at 80C peak. I will first detail what I did and then ask the questions. I run just +50 or +100MHz and all it seems to do is make it run hotter with almost no measurable improvement other than showing 5+GHz in hwmonitor. I am seeing great improvements for both single core and all core workloads and temps for example - Using PBO2 makes my 5900X boost happy!#Shorts #Ryzen #AMD #5900X. 95ghz with 4. I also kept a spreadsheet to track Overclock with PBO2 AMD 5900x - Aeros Master . 6 boost 4. This isn’t an issue in games however it seems strange as my Asus strix X570 did not behave like this while running benchmarks. Xxdarkshot1986xX know-it-all Member. 3v+. Coming from 15 years of Mac usage all of this was new. The test was repeatable and data consistent. I few months ago a bought a 5900x, one of the first batch and in had the opportunity to play a little with OC but with the release of PBO2 and curve optimizer I found myself reaching the limit. 65GHz stock for the 5600X, PBO2. 95ghz. us/YuQmAMD Ryzen 7 Given my 5900x is OCable via PBO2/CO and the 5800X3D has been announced as not OCable, And that 10% is over my 5900x's stock performance, which in terms of clockspeeds and such is going to be higher than the 5800X3D's stock clockspeeds because AMD has deliberately lowered it due to temps and such. That's at ~16°C cooler ('near-stock') and reportedly slower. 5900X is 105W TDP CPU which can draw around 140W at full throttle, mostly in synthetic benchmarks. 903. I’ve run lots of full Cinibench R23 and no crashes or WHEA. Automate any workflow Codespaces The 5900x, having the lesser chance to get better with tuning due to the lower bin, has an advantage. From what I understand there isn't too much headroom to be gained from tweaking and tuning outside of pbo anyways and would prefer to have stability over squeezing a few percent extra out from hours of testing so I've left most of my gigabyte b550i ax bios settings on auto. What BIOS are you on? Could never get my buddies 5900X to behave how I thought it should on that board, and his best score in Cinebench R20 was around 7500.

CCX0 easily boosts to 4. Intel Core i9-14900KF. I think it's overall nice. CCX1 boosts to 4. The 5600x in my new A520 board goes to 4. Single Thread 668. Your temps are great, dont worry about them. For stock clocks, even down to the 65W TDP numbers (88 PPT, 60 TDC, 90 EDC), my Cinebench R23 single-core hardly moved and my boost clock was still hitting up to 4. So, it strikes 22400 score on Cinebench Meu 5900x otimizado com as informações deste tópico está marcando 83ºc após rodar o CinebenchR23 multi core (22792). Right now I am working on the curve with manual set stock PPT/TDC/EDC I've worked my way on the cores to -30 on all except 1 core at -14 and one core at -17, I seem stable with no PBO2 and the curve optimizer are worth trying out, and for gaming should be better than a static overclock My 5900x is oc'd to 4. 75ghz MT during cinebench R20 runs. There is no doubt that AMD has broken into the so-called PC gaming market in a notorious way, a sector that until now was dominated by Intel and that as such, seemed not to be in danger. I'm using PBO2 to increase the performance of my 5900x. Stock temperature limit I think is 90C. I have same problem with you too until I set pbo2 with eco mode 65 watt. The performance doesn't actually improve at all and I keep having issues where the system will just randomly crash. 95GHz and regularly sustaining over 4. 1% higher ave all-core speed or Along with the AMD Ryzen 9 5900X processor and GIGABYTE X570S Aorus Master motherboard, in this guide, we will be using a pair of Aorus RGB DDR4-4400 memory sticks, an NVIDIA RTX 2080TI graphics card, an 512GB Aorus RGB M. In cinebench R23 I even got almost a 1000 points higher score, but the temps stayed the same. 2. The new PBO2 does help a great deal across the board from what I have seen first hand and read about.
