I bought 3 new MSI 6950 Twin Frozer II/OC back in June 2011. I unlocked only the shaders with all 3 cards and they were great cards while the fans lasted. I had 1 fan fail on every card within 5 months and the other fans were struggling as well. I don't know what kind of fans they used but I was astonished in how fast the bearings/whatever type of fan they used failed. I ended up leaving my main chassis open and just had a big fan blowing on them whenever I gamed to keep the temps below 82C.
I shipped all 3 cards to MSI on 12/19/2011 and I just received the cards back on 1/11/12. All 3 cards were in separate boxes and looked to be shipped well.
Now the Problems
I unistalled my 2 6870's which I were using in place of trifire until I received my RMA'd Cards. I uninstalled my AMD drivers and installed a single 6950. Upon driver reinstallation everything looks good and seems to function fine in windows. I then Shutdown and reinstall the 2nd card for crossfire. Upon booting up and getting into windows it starts artifacting within 20 seconds. I then decide to shutdown and remove the last card I just installed and rebooted again. Now the original card is artifacting. So thinking that their is a driver issue I uninstall driver, restart, reinstall driver, restart. Upon starting up it artifacts again in windows. I remove the last card installed and boot back up in windows again and the original card is now artifacting. I'm thinking maybe theirs a bios corruption issue on a card so I end up flashing it with my original 6950 bios on my previous card that I RMA'd. The bios issue didn't fix or change anything. The only thing I notice is obviously the full shaders are unlocked.
So now I'm thinking what the hell is going on. I take another rig and just decide to do a quick windows 7 install on my MSI h61 board. This would eliminate any potential issues with driver corruption or faulty hardware. The card under any video load or even microsoft windows 7 experience index test causes the driver to crash. I then remove this card and decide to try the 3rd MSI 6950 card and run that in the H61 setup and see if it works fine. This 3rd card I just removed from the MSI RMA's box and installed it for the first time in my rig. Go figure the 3rd card installed by itself is artifacting as well and this was tried in my X58 rig as well as the new installed H61 setup. I didn't touch the bios on this card or crossfire it either so I'm totally stumped at the moment.
I've tried 2 different psu's of mine both being Corsairs AX1200 and my Corsair AX850. I have 2 more rigs I can dissasemble and try the cards in there but I don't think it will make a difference.
The next thing I'm going to try is an older catalyst driver. I'm currently using catalyst version 11.12.
What are the odds in getting 3 RMA'd cards back from MSI with all of them artifacting? I've been a long fan of MSI and own 1 MSI 560 TI, 3 twin frozr 6950's, MSI H61, MSI H67, MSI P67, and two MSI Z68's. This RMA experience right now is definitely putting my patience to the test.
