Hey guys

I have a galax gtx 970 but the problem is the voltage is hardware locked and i want to push my clock further that 1522Mhz in order to beat personal records on 3d mark. its a non reference PCB and it has the Richtek RT8802A for the voltage controller. I found a comment on the kingpin forums (http://forum.kingpincooling.com/showthread.php?t=956&page=38) about doing it, i tried what was reccomended and it did not work (voltage did not move at all and neither did the temps). It just made my card coil whine like a bitch if i adjusted it to far one way, so i end up using the mod to help stop my card whining by adjusting it the other way. I have a feeling i may have to put a POT on the Feedback return pin of the controller to adjust it. Any advice would be greatly appreciated.

I think you can mod the BIOS for voltage control instead? At least I know you can undervolt this way, so overvolting should be possible.
