CPU voltage configurations
CPU voltage configurations
do any ofthese settings seem out of order? Im running a b650 aorus pro ax. I have no oc only pbo enabled. The last 2 settings (cpu and vcore loadline calibration were set to 6% i set them to auto). Reason im askingbecause im having problems with dx12 games occassionally crashing on fullscreen mode, seems to be speficially also when framegen is enabled. One guy said he fixed it by disabling asus multicore enhancement on his intel platform but i dont know the equivalent to that on amd. I know for a fact it isnt a hardware problem cuz i replaced everything and still had the same issue, only thing left is the mobo and im sure a faulty mobo wouldnt cause dx12 games to run fine on windowed fullscreen but occasionally crash on fullscreen
The B650 boards are really solid for budget builds, or maybe the 620 model wasn’t available yet. The Pro AX stands out as a high-end B650 option, beating the X670 in performance. Your voltage settings are just right. Don’t mess around—stick to the default PBO/CO (-30 for core) and just enjoy. No need to tweak anything unless you’re working with the 7950X3D; @Agall has done thorough testing and might have some adjustments.
Are you using the 3D v-cache optimizer driver or overriding CCD0? For voltage adjustments, keep them unchanged except for PBO2 offsets. EXPO may occasionally adjust RAM voltages for stability—turning it off and testing might help. Concerning fullscreen versus windowed crashes, the issue could stem from the 3D v-cache optimizer driver. I haven’t used it since the initial test and observed minor frame time delays. My advice is to adjust CPPC settings, typically under SMU in the UEFI, which disables the driver as it handles the Auto option.
I mentioned cache preference earlier, but it would crash too. So I switched to auto and installed the 3D VCache drivers, yet the problem persists.
Additionally, I attempted a 7600x configuration on my motherboard and encountered the same problem, suggesting it might not be related to a vcache driver issue.
AMD overclocking followed by adjusting CCD0 to 0-0-0-0-0-0-0, often referred to as 'down mapping,' is a feature found in the menu settings. Once fully set up, it displays all ones for both registers and restarts the process within that menu after changes are applied—this avoids the usual 'save and exit' behavior. For troubleshooting, down mapping can be useful. Alternatively, you can use Processor Affinity in the Task Manager's Details section to specify which CPU core an application should use, starting from 0. This method works in real time and lets you test different core assignments for your game.
