Yeah, I may give this a go at the weekend.

For now, it's folding at 1050 / 1400, with max temps at 76 with the fan set to 44%.
The ASIC quality is 66.6%, not sure what that means, people seem to have varying opinions on weather a higher or lower value is better.

Am I right in thinking that I can just increase the clocks, test for stability and keep going?
I'd like to use my card for a few years, as I did with my 6950, so if I don't want to over - volt it, is that the best way of overclocking?
I presume that by just seeing what it can do at stock voltage, I can increase the longevity of the card?

Also, I believe that my card has a 7970 PCB - it has 8 + 6 power connectors - does that mean I can put a 7970 BIOS on it?
What effect would that have?


Thanks.

set higher fan speed. try 50 - 55%. keep core temps around 70c and VRM temps below 90c.that will help in improving stability. also don't mess with the BIOS. you could brick the card. just stick to manual overclocking and custom fan profile if needed. 1050 - 1100 mhz at stock voltage is good if you can achieve complete stability in games / benchmarks / folding. also voltage tweaking is not going to adversely affect life of the card. try small voltage increments of 0.05 - 0.1v. whats your stock voltage. you could hit 1150 mhz with a bit of voltage tweaking.

Thanks!

I won't bother messing with the BIOS, doesn't look like I need to.
I'll post some pics of changing the TIM at the weekend to see if I have a 7970 PCB though.

With an overclock of 1075 / 1500 and auto fan speed, it was stable through two hours of Valley, which max core temps of 74C, and VRM temps of 71C and 80C.
I haven't yet folded at this OC but if it's stable I think I found my clock!

From the looks of it, MSI afterburner has clock limits of 1100 / 1575, but the voltage can go much higher.
Stock voltage for my card seems to be 0.950V at idle and 1.188V under load, is that any good? tongue.gif

I've dropped down to 1040 / 1500, and after much folding, the core doesn't get any hotter than 69C with auto fan speed, with both VRM's staying under 75C.

If I drop the Fan speed down a bit to 44%, it peaks at 76C, and the VRM's at 75C and 80C.

I'm pretty happy with the overclock unless anyone can see something I've done wrong!
