Hello, about 3-4 weeks ago I had some problems with my Gigabyte HD5850 (reference design), the core and memory clocks would be 710/900 respectively when the default core and memory clock for HD5850's is 725/1000, I sent it to the E-tailer I brought it from and they tested the card and said they couldn't find the fault, So they decided to send it to Gigabye for further testing. After about a week I received my card back in the post and was told the card had been repaired.
Sure enough when I installed the card and booted into windows the core and memory speeds were as they should be (725/1000) which was great news. After about 2 weeks use I received a Bluescreen during a run of the benchmark 3DMark11, I thought this might be because of my CPU's (Core i7 920) overclock, so I ran a CPU stress test program called OCCT, after about 25 minutes I received a second bluescreen, At this time I was pretty sure my CPU was the cause of the bluescreens...
However after returning my CPU back to stock speeds and setting my RAM to run at its rated values I was still getting bluescreens. I decided to check GPU-Z to make sure my graphics cards were running as they should....Here is what I found.

Haven't had a bluescreen since removing the gigabyte card..Your opinions?
