motherboard XFX 790i Ultra 3-way SLI
9800 GX2 in the first PCIx slot
tesla C870 in the second PCIx slot
Intel Q9300 quadcore
CoolerMaster 1000W PSU
Windows XP 64 Profesional
9800 GX2 and Tesla C870 are not connected via Sli bridge
After installing 169.21 drivers 9800 GX2 is not recognized and GL window inside Nvidia Control Panel is empty. I uninstall that driver and try with 174.74. After that windows recognized both 9800 cores and GL works fine but now Tesla is not recognized. Why?
Is it possible to make all three GPUs work and how? Which CUDA version should be installed to support all of them and which nVidia driver version?
Since one PCIx 16 is still free can I use for example an extra GeForce 6800 card as display adapter and have all 3 GPUs available for CUDA?
