I currently have evga gtx970 blower type with arctic cooling mono plus heatsink on it, temperature never reach above 53c during furmark and 45 during gaming. Right now I have it clocked at 1452/7880 1.2v stock voltage. I would like to push it to 1452mhz, but anything higher than 1452 will give me black screen. Is there anyway to unlock my gpu voltage? I used evga precision x16, tried to add 12/25/100346734mg, but voltage stayed at 1.2v, any ideas?
