Hmmmmm, maybe more voltage. The o/c u and I both have is relatively low.
My nonref sapphire 6970 (7 voltage phases) passes kombustor extreme burn in, gpu stability test, and kombustor benchmark at 980/1500 on stock volts. However, SC2 will freeze after 15 minutes or so. Had to drop to 970/1475 for stability on stock volts. I'm sure a slight voltage bump will fix you. Something about real world gaming trashes these things. Maybe the mobos are being drained of enough voltage by the cpu that the pci express voltage tanks a little and trashes the card. When the cpu and gpu both max out at the same time,its over. Just a theory.

BTW, have you tried adjusting the powertune settings in ccc?

I will call MSI and see about that before considering rma. It runs great on the silent profile and this card oc's great.
Make sure your BIOS is in the second not third position. I found this link on Xtreme systems. Refer the 3rd and 4th post.

I have confirmed on my 6970 Lightnings that there are indeed 3 positions. However, I have not installed the cards yet (going to build my new rig all at once after Bulldozer launches) so I can't confirm if will POST or not.

Summary of link: Third position won't POST. Move the bios switch to the middle position and see if it POSTs with the increased CCC limits and 2.5x power tune range (i.e the "performance" settings).

Wow, your would think that when you drop $400 on the top of the line card the documentation would be better then the crap they give us. Who knew that the switch was a three position switch. I have read every review posted on this card and not one guy knew there was three positions.

When I call MSI, the dude didn't even tell me. Wow, Fail.

LOL! And I thought I was the only one who thought that when I had it. Overall, it's a nice GPU but definitely not worth the price, IMO. Glad I was able to get the majority of the money back Hope you all enjoy that Lightning more than I did

Ok, restarted in the middle position, posted no issues.

DrBlah, I really think the best option right now is 6850 CF.

2 6850's are right around the 6970 price and the performance is better.

Im hoping this card really shines as the drivers mature.

Thanks, I am planning to really push these cards in CFX so the extra headroom in the powerTUNE settings afforded by the second BIOS is necessary.

And, I agree big MSI fail on providing no information in box on this one. Especially, if you considering where "performance" is written on the back of the PCB. It really looks like you should use the third spot.

Wow.... before you change the position, look at the thresholds on CCC and AB,

Note max positions. After you move the slider to center and restart, check out the thresholds now for CC and Afterburner.

I DID NOT USE THESE SETTINGS. I just slid them to max to show the range available.

Yeah, the clocks really open up. Though the PowerTUNE settings seem unchanged. The guru3D review mentioned throttling, so I am most concerned that you will get bad performance scaling above 1025Mhz or so if you are limited to only the +20% power setting. Sorry to keep asking things, but did you see any difference in your PowerTUNE options before and after flipping the BIOS switch?
