GPU Auxiliary voltage help, what does it do?

post #1 of 8
Thread Starter 
Hello OCN'ers.

So I am wondering about the Auxiliary voltage that I can adjust in Afterburner on my 780 Lightning.
What is it exactly? Will I get any higher core/mem clock by raising it? Never really understood what it do.

Thanks for any help!

The aux. voltage is the PLL voltage for the card, I haven't touched it yet to see the effects. Hoping I get a chance to OC the 780L next weekend.

Ah ok, nice! Thanks. Will max it to then, stock it can go +100. Perhaps I can get a little extra core out of it.

the aux slider in msi ab regulates the voltage drawn through the pci lane. increasing it can help core clock stability. for your card +100 is from 1.050v to 1.150v.

Doing only +10 on aux made my memory go from 1380 to 1450 with headroom. If you ask me if I could get it higher I would tell you this aux voltage fried my Club3D R9 290. I had 1210Mhz Core and 1450Mhz Memory stable for 5 minutes before it burned down. Chip wasn't burned though. It was like 82 degrees. RIP Club3D R9 290....

It controls the imc - useful for memory instabilities.
