BIOS

Hi, where can I find the CPU Clock option in the bios on the ROG STRIX X870-F GAMING WIFI motherboard? I've looked for this option and it's nowhere to be found, and I want to do an undervolting of my Ryzen 7 7800X3D and set CPU Clock to 48 and CPU SOC Adjust Vlotage to 1.200, but I can't find the CPU Clock anywhere

Hi @AnoX 

Sounds like you need Per Core Boost Limit and Curve Optimiser, both of which can be found under the PBO menu. 

Alternatively, you can use tools such as Ryzen STD

SOC voltage override can be found on the Extreme Tweaker menu. Whenever making such changes, be sure to test for system stability.

And how much should I set to a single core in Per Core Boost Limit to have it set to 48 overall?

[Silent_Scone]

That's surely down to you to decide, isn't it? Personally, I wouldn't set all core to 48x. Leaving too much performance on the table.

Depending on the silicon quality, it's possible to achieve PBO frequency and beyond with reasonable voltage. My 9800X3D sample does 5.533GHz @ 1.117v.

If I try to type 48, it changes my number to 3600

I want the CPU ratio to be 48x, in my case it is 42x. How to change it?

42x is the base clock. Put load on the system.
