I'm reaching 75C in Cinebench R23 continuous loop. I think most people could turn on XMP and optimize PBO limits and do an all-core curve offset, and test for a day or two and get good Adjusting PBO limits is a bit of a game with how agesa behaves differently depending on mobo and bios. So far I've left most settings on auto, set pbo to advanced, power limits to motherboard, boost override to +50 MHz, core optimizer to -5 all cores, and set everything else to auto. PBO does not raise your CPU's max boost frequency, which is 4. Hits max 63-63. I set the PBO limits to Advanced/Motherboard, and on my AORUS X570 Master, it cranks the watts and speed. Each time I just get bsod with WHEA ERROR. That's all it's good for. seems to be stable at -5 as well. Btw, limit Edc to no more than 180a to be safe. PBO raises the current and power limits that govern your CPU's boost algorithm.

What is a 2ccd motherboard and what does it mean to set limits to this option? Next, he states that alternatively, you can assign manual PBO limits for PPT, EDC, and TDC. I have had some issues for a while with the temperatures of the CPU (I know the 5900x does run quite hot for CPUs, but have seen some people who have full load temps of like 70-80 and am quite jealous lol), as running most games or things like Cinebench You probably disabled the power limit when playing with PBO and curve optimizer. This actually lowered my idle temp around 7 degrees after lowering my chipfan curve due to noise. +50 auto-oc, vcore -0. Latest bios, cooler is a NH-D15. I’m not really experienced enough to be running dozens of tests on thermals and playing with complicated settings like PBO limits, PPT limits etc etc. PBO Tuner is a great program to test different settings on the fly without having to keep restarting. /r/AMD is community run and does not represent AMD in any capacity unless specified. 4W. . So I tested my previously determined CO values and passed the test. Set it to advanced, pbo limits to manual, 250 PPT, 250A TDC and 250A EDC. VID stays around 1. Thermals are limiting clocks. PBO2 set on auto, so disabled. 104 votes, 516 comments. With “default mode” in RM, my temps occasionally tickle the low 60s in extended CR23 runs and idles well under 40. PPT 220 TDC 165 EDC 135 Curves -10 on 1,4, -15 on the rest.
