I upgraded a 6 year old computer to Win 7 with a new CPU and Mobo and PSU, now I have no SLI in games! Runs stable so far in daily use. It scored Windows Experience Index of 5.9 with one video card installed and a whopping 6.0 in SLI in the Graphics and Gaming Graphics sub scores. I know the cards are (very) old in terms of GPUs, but I was hoping to squeak out a few more years.
Motherboard: Asus Sabertooth X79
CPU: Intel i7-3820
Cooler: NZXT Kraken X40 (85 degrees F)
PSU: Cooler Master Silent Pro M2 850W
GPU: Asus GeForce 7800 GTX (x2)
Drivers: 220.127.116.113 Dated: 1/31/2013
OS: Win 7 Ultimate 64 bit
Mem: 8G Corsair Vengeance (2 x 4G)
Drives: 1 optical Plextor DVD
1 Samsung 256G SSD
1 150G Velicraptor
2 WD 250G
I have the newest drivers from Nvidia installed and SLI enabled from the Nvidia control panel. I have installed some older title games and had failures in each case. It BSoDs in Bioshock or dumps the video to the desktop in Medal of Honor. I can click the program in the task bar and the video comes, flickers and dumps back to the desktop, however the program does not terminate. Since it happens at the launch of the game and the temps seem cool I have not considered heat to be the factor and with a new 850W PSU I am not leaning towards that as an issue.
Bioshock would BSoD: STOP: 0x0000016 ... (more interesting is) nvlddmkm.sys also shows up as a culprit, an Nvidia driver file?
I have tried replacing the nvlddmkm.sys from the .sy_ file and no luck. The device manager see both cards, they both are plugged into the PSU and the SLI bridge is installed.
