A redditor was able to help. It's funny, it was actually right there in front of me the whole time on the OC tweaker BIOS page. Platform thermal limit. Free form field. Descriptive text is what fooled me, since it says it's for allowing the user to lower the thermal limit. But you can put 95 in to raise the thermal limit and it accepts it and that worked. Cinebench now hovers at around 91 degrees. ]]> Tue, 07 May 2024 02:40:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119216&title=how-to-limit-tdp-on-b650m-pro-rs#119216 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119040&title=how-to-limit-tdp-on-b650m-pro-rs#119040 Author: sgunnone

Motherboard is on bios version 2.10, and temps were reported by Ryzen Master under Windows 11.]]> Mon, 06 May 2024 08:40:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119040&title=how-to-limit-tdp-on-b650m-pro-rs#119040 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119039&title=how-to-limit-tdp-on-b650m-pro-rs#119039 Author: sgunnone

I have another question. I ran cinebench to get a baseline before I made any changes in the bios, and I noticed that the CPU was being limited to 85 degrees, even though it's a 7950x, which should limit at 95 degrees. Is this a limitation of this board?]]> Mon, 06 May 2024 08:28:22 +0000 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119039&title=how-to-limit-tdp-on-b650m-pro-rs#119039 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119032&title=how-to-limit-tdp-on-b650m-pro-rs#119032 Author: M440

no problem.

You set the undervolt in the 'Curve Optimizer' menu in the said PBO section.]]> Sun, 05 May 2024 23:35:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=119032&title=how-to-limit-tdp-on-b650m-pro-rs#119032 https://forum.asrock.com/forum_posts.asp?TID=35967&PID=118936&title=how-to-limit-tdp-on-b650m-pro-rs#118936 Author: sgunnone

one way is to set it using the 'OC Tweaker' preset.

the other way is to enter the (AFAIR) Advanced-AMD Overclocking-PBO, set PBO to advanced and there appears the field with [mW] units, so setting 105000 is 105 watt limit.

Sure you should undervolt those CPUs - they run cooler and boost the clocks higher with lower power consumption.

You do this by simply setting the undervolt (like -15 ) and stability testing in the OS. If you do this for all cores than you can even do this per core for ultimate chip optimization.

For stability testing i recommend Aida64, because it was the fastest to give desirable results (crash if you undervolted too much!).

Below is written how to set up per core undervolt. Its supraisingly quick and easy to do, because it was enough to run Aida64 for ~3 minutes to check the stability.
