Hey guys,
Is there any way I can pass 1350mv ?
Im using afterburner, I have everything else unlocked but I cannot go past 1350mv thats the max voltage.
Ive tried both bios...
My cards are both under water and im not reach nearly 60c so I think I can push a bit further for benching...

there are soft mods such as flashing bios or hard mods such as changing resistance of capacitors on the pcb if you have electronics degree lol

I don't know how safe it is to go past 1.35V but you might be able to edit the BIOS with RBE (if the BIOS is supported) and increase the 3D voltage value, then you'd have to flash the edited BIOS to the card but make sure you create a backup of the original BIOS with GPU-Z.

Can I ask a few questions? Are you using the boost lightnings i.e. 1150 mhz/ 1500mhz version? with EK water blocks (EK-FC7970 Lightning)?
Thanks a lot.
