hey, I just get this card and want to OC it. now it can go as high as 675/830, but in games the card crashes after something like 10 mins of gaming. I want to get the card stable on these clocks, so I edited my card bios with rabit, and configed the VCORE to 1.425V, this bios doesn't support higher voltage. Can anyone please give me a bios with a VCORE of 1.45V at least that matches my card? I put a great cooler on this card so temps isn't problem. Thanks in advance.
