to enable voltage in MSI afterburner do this:-

Alright, thanks. And what purpose does "force constant voltage" do? Is it recommended I use that if I OC, or is it only optional?

Oh and before I brick my PC again, guru3d said they OC'd this card at 1.2 V to 975mhz core clock, but the memory clock confuses me, because they say stock memory clock is 5600mhz, but in MSI it says stock is 1400mhz. Or is the real memory clock 1400 * 4 = 5600? But it says they OC'd memory to 6300 MHZ @ 1.2 V, which would = 1575mhz in MSI, but it only lets me go to 1500 max with memory clock.

its optional, and i don't think you need it. i don't know why i even checked it ?!! i'll uncheck it now.

as for what it does, it just make sure your graphic card get the same voltage at all time, on idle and full load.

and yes memory clock 1400 * 4 = 5600

well they must have used another software to overclock the card. some software allow to go as high as you can, other have limits.

Looks like stock core voltage is 1174 MV, so I would need to change that to 1200 MV? Also edited my above post, the max mem clock it lets me do is 1500mhz or 6000mhz mem clock.

Um, this is really odd. I upped the voltage to 1200MV (1.2V), increased the Core clock to 975 from 900, and Mem clock from 1400 to 1500, and I get a decrease in performance?

I'm getting a 10 FPS drop in Witcher 2 on average. I also noticed my GPU usage dropped off the cliff, stayed in the high 80s 90% and it dropped down to 60ish % usage.

Any reason why this would happen confused.gif
