Since some of you guys were asking what I built, thought I'd start a thread.
Nothing too special, but not bad for my second build ever. My last build was about 10-11 years ago. It is now displayed at the Smithsonian.
Case: Antec 900 1 x 200mm top fan, 2 x 120mm front fans, 1 x 120mm rear fan, 2 x 120mm fans on heatsink.
Did you flash with the 6970 bios or unlock the extra cores. The 6970 memory have different timing and voltages. I have the asus 6950 and I got random blue dots on anything that was dark using the 6970 bios. I just used my stock bios and unlock the cores and overclocked to the 6970 speed. Some people have burned up there cards using the 6970 bios. Curently my card is at 900/1450 at 1.13v the max I have ran stable is 962/1554 at 1.175v.
Its more to do with the 6970 bios you should flash back to stock then use techpower radeon bios editor to unlock the cores. All you do is load your stock bios then click on additional features tab then on the middle right click the 6970 shader count and save as a new bios and flash it to the card. Then over clock to the 6970 speeds and you should be good.
Let me know if you want help I don't want to see your new video card end up being a paper weight.
Also make sure ati overdrive is set to +20% or you won't get enough power to the card.
