Hello everyone,

Newbie overclocker here...

I am trying to identify the VCCIO and VCCSA values of my motherboard via the HWinfo software.

Mobo is: Asus TUF Z390 Pro Gaming

I suppose the VCCIO is the one which states 'CPU VCCIO' and has a value of 1.344?

But i can't find the VCCSA. Can you help out please?

Thank you,
JH

Officially your mainboard doesn't support monitoring of VCCIO and VCCSA.
VIN7 might be the VCCSA value, but this is just an assumption. You should compare this value with the one set in BIOS.

Thank you for your response. Appreciate your time.
Unfortunately its not VIN7, none of the other readings display the value (or a close approximation) of the VCCSA i set in bios (1.17). The only way to monitor the VCCSA is to use the AI Suite of Asus.
General question: Does adjusting the VCCIO and VCCSA affect CPU temps? I've tried lowering to 1.17 for both, and temps dropped in stress tests by 2-3 degrees. Could this drop be due to margin of error or other random factor? Or does the adjustment affected the temp?
