I have four of the NVidia interface cards in a Windows 2008 R2 server. If I connect 3 of the cables, the system boots, and all sixe GPUs are active. If I connect all four cables, the system stops after the Windows status bar.
I have disabled the onboard NIC, RAID and any other PCIe devices. Neither the 197.03 or 197.45 drivers will work.
This used to work with Windows 2008 server.
Any ideas?
