Why can't I adjust voltage in MSI Afterburner?

post #1 of 4
Thread Starter 
I have modded my Gigabyte 780 Ti Windforce OC to use skyn3t's vbios http://www.overclock.net/t/1438886/official-nvidia-gtx-780-ti-owners-club

but sliding the core voltage and applying doesn't do anything? I have tried extended MSI option but that only changes the GPU VRM voltage not the GPU Core voltage which is pointless... However PrecisionX16 works fine? How come?

I already have as you can see from my screenshot, even restarted my PC.

A couple years ago, In the 780 Ti thread, skyn3t posted that only MSI cards had full support for Afterburner.
This is why you can't do any voltage changes with your Gigabyte card with Afterburner.
But EVGA PX does work.

I had the same issue with my EVGA 780 Ti's, so I had to use PX exclusively.
