Does the I/O voltage (VDDCI) on RDNA3 serves as the baseline for core voltage, just like all previous AMD GPUs?
For example, if the VDDCI is internally set at 800mV, would I be able to apply a voltage lower than 800mV on the core? Or would the core simply refuse to run below 800mV?
The reason I'm asking is because More Power Tool is incompatible with RDNA3 GPUs, and More Clock Tool appears to have very basic functionality with no option to tweak VDDCI, unlike RDNA2 and RDNA1 cards.
And I'm just curious if it's even possible to run RDNA3 based GPUs at super low voltages for purposes other than gaming?
I'd be absolutely grateful if you could spare a moment of your time and test if it's possible to run an RDNA3 card at voltages as low as 650-700mV.
Thanks in advance!
