For the last several months i have had many problems with my card and tried many things. The problems i am experiencing are i believe commonly related to TDR but may go beyond this.

During games my graphics card will either crash and return causing a black screen for 3-5 seconds, crash and not come back up leaving the last displayed frame on screen, or create a blue screen of death relating to TDR issues.

I have attempted updating all of my drivers and bios, clean install of my gpu drivers,using a different gpu and taking my gpu in to the store i bought it at. the other gpu experienced no problems, the store refused to replace it as they could not find anything wrong with it.

I really don't want to mess around with the voltages and clocks so this is my last hope.

Thanks, Sam

Thay may be part of the problem, the DRAM base timings should be 9-9-9-24, I'd suggest go into BIOS, enable XMP, and select profile 1 for the DRAM, then find DRAM voltage and set to 1.55, save, exit, reboot back to BIOS and see what tRFC (DRAM REF Cycle timing is at, if still at 110, try it at 160)

If a different Graphics Card worked fine then your card is almost certainly defective.

It might possibly be your Power Supply but if the other card was a 660Ti or better and worked it's not your Power Supply.

Not sure why the store says it worked though.

I'm pretty sure the card is defective but I don't know how to help you further.

The store told me they ran heat/stress tests and ran graphics intensive games for 24 hours. my power supply is a ax750 corsair and it has no faults i can tell all voltages check out

Attempting a possible solution from microsoft.http://support.microsoft.com/kb/2665946
hope it works but it looks like a mask to the problem not an actual solution. regardless it will get me back gaming while i wait for help.

After some testing i have discovered that it only crashes under load and heat, i can play games on low or high graphics but when a lot of stuff starts happening in a scene the crashes start and continue till i give my card a rest

PSU should be good, but might try a different one (if you don't have one might see if you can borrow from a friend to test with)...another possible is DRAM, you show 4x$GB was this a single package you bought or did it come in two different packages, if so may be slight incompatibilities, what is the actual model number(s)

The ram are two packs but exactly the same and i kept them in the right slots one set slots for the package. When the problem started nothing had distinctly changed i hadnt changed any hardware for three months. I will look for the dram model numbers but no promises if i can find them.

Might want ot try going to the BIOS and check that the base timings are correct and raisie the DRAM voltage to 1.55 (the sets you have are 1.5....also take a look in the Advanced DRAM timings and let me know what the tRFC is, should prob be around 160-178
