Hi there guys,
I have just acquired a pair of Asus GTX 670 Direct CU II cards and put them into SLI. But I am getting intermitt crashes (not blue scrren - just a sudden restart and sometimes a RED screen and then when it boots the PC sees only 1 one card. Then I restart the PC and SLI is back until it crashes again. I am watercooling them and Ive checked the temps - they are fine. I have run Furmark for over two hours stressing the cards and all was good. Crashing can be in long or short intervals. I have upgraded from a AMD 6990 which I had no issues with.
I have uninstalled all monitoring software/reinstalled drivers (using driver sweeper)swapped SLI link cable/cards run fine on their own.
Just this morning I thought it was fixed - left Dishonored on for a few hours only to come back to a desktop screen - game was still running in the background - clicked on the game and it was still running fine but 1 card had disappeared from the system and it was just using the one card. Checked Nvidia Software and no SLI - rebooted and back to SLI.
Any suggestions?? Im thinking of possibly reinstalling windows and see how that goes otherwise Im thinking power supply. Its about 3-4 years old - didnt have any issues running a 6990 but you never know could be on its way out.
My specs:
Intel 3930K
Asus Rampage IV formula
16GB G Skill F3-17000CL9
Soundblaster Titanium HD Sound Card
Corsair HX 1000W
OCZ Vertex 3 MAXIOPS SSD
6 other SATA physical drives
Running Windows 7 64
Latest Nvidia drivers 306.97
thanks,
