Thanks. Yeah it is set to +20%, I didn't even know what it did at the time, I just saw everyone else setting it to that...

Thanks, I just dowloaded Heaven now, gonna do a test at 1200/1700 1.150mV and see if its stable smile.gif

What kind of temps are you seeing at those clocks? I see 85C with 1250mV at 100% fan and you are running CF :O

General_Jaja: I found that I was stable in Heaven 3.0 and 3D Mark11, but would crash in BF3. In my opinion BF3 is the best indicator of stability. If you don't crash while playing BF3 you don't have to run other tests because you are stable. biggrin.gif

1200 core @ 1.150 is a sign of a great card. I need 1.225 to be stable in BF3 @ 1200. thumb.gif

Although 70C seems a bit high as I am using more voltage and never go over 60C during BF3 etc... although it might be due to the fact that the Gigabyte card has the best third party cooling. 70c is nothing to be worried about though as long as you don't go over 80c while playing games I would not worry about it at all.

Temps are about 67 degrees whenever I check, and the fan speed around 53%. Best time for overclocking at the moment, nice and cold!

My games run smooth like butter! I was originally anticipating the Nvidia/EVGA GTX 680 FTW 4gb card, but its like an needle in a hay stack just for the reference cards so I made a leap of faith and i'm content. I'm in the process of getting a water-cooled setup together and really like Swiftechs Komodo HD7970 block. However have had a weird monitor suspend / sleep / wakeup issue with AMD's latest Catalyst 12.4. I have a solution that seems to work for me. Hope this helps someone thumb.gif

Swiftech Komodo makes baby jesus cry from all the restriction.

Mines maxed out at 60degrees with 54% fan 1.19mv 1250mhz 1600mhz tongue.gif When summer comes we're all going down though. What's your asic quality btw? 1.15mv is crazy

I can do 1100/1600 on stock V , but no matter how much V i can't go past 1150 Core!! my card doesn't like anything above 1150 Core, i can do 1750 Memory with no problem too.
