Gigabyte 7950 Rev2 Overclocking

post #1 of 2
Thread Starter 
I got a 7950 rev2 used a while ago and I'm trying to overclock it a bit.

From what I understand the voltage is supposedly locked at 1.25, but the strange thing is that GPU-Z is showing 1.113v I am able to get decent clocks and temps (1100/1500/63c furmark) at these volts but I'm wondering if GPU-Z is just reporting it wrong or maybe the last owner did some kind of bios mod.

This card does not have any VRM sensors so overclocking is a bit risky I guess, but the Rev2 has a much bigger VRM heatsink compared to Rev1 so it should be OK.
