Hi guys,
So basically I done goofed. I bought a 7950 a few months ago and everything was going swell. I upgraded my mobo BIOS yesterday just because it was 3 years old, and I figured there might be some optimizations for my brand new graphics card. Well, the bios said it upgraded successfully, but then refused to post, even after resetting cmos etc. etc.
I went out and bought a new board, my old one was a p67 sabertooth b3. I figured hey, apart from screwing the BIOS up the board was pretty good. So I bought the Z77 version.
I kept all my old overclock values (took pictures before I updated the BIOS knowing that I would have to reset it), but now that it's come time to enter them again I'm having to give my processor more vcore on what (I assume) is essentially the same board.
I have a 2500k at 4.4ghz, and all the settings are the same except before I was doing offset -0.005 with a medium LLC and that was stable (20 runs of IBT, no blue screens at all since the overclock). Now I'm having to go Ultra High LLC with an offset of -0.040. The load voltage is now about 0.02 higher than before - I didn't want to keep the medium LLC because the vcore was spiking a bit too high for my liking after coming off load. It used to sit on 1.31v, now it sits on 1.33v full load.
Is this something to be expected between boards? Even similar ones? Nothing else has changed in the system. Full load on IBT I'm hitting 76*C max, which shouldn't be an issue at all. Don't really want to push the voltage up more...just disappointed that I've had to redo my overclock. I know that 1.33v isn't a particularly good voltage for 4.4ghz, but I guess I just got a below average overclocker.
Thanks guys
