Does anyone know how to change the DRAM voltage? It appears no where in the BIOS. I am very baffled, where it should be, it is not. My XMP profiles do not work, and I can only OC my RAM as much as the stock Voltage allows me to. Help would be appreciated, thx.

Hi urbanrace6,

Thank you for your post.

The voltage of the DDR5 motherboard is a little different from the DDR4 board.

For example, If you would like to set the DRAM voltage to 1.35V.
You need to change VDD and VDDQ at the same time.

These two values are under BIOS\OC Tweaker\Voltage Configuration.

All the best
