I have just purchased the following spec and cannot get SLI working:
Corsair 2GB DDR XMS4000PT TwinX (2x1GB) CAS3
AMD Opteron UP 144 San Diego 1.8GHz 1MB Cache (Socket 939)
DFI LanParty NF4 SLI-DR EXPERT (Socket 939) PCI-Express Motherboard
Thermaltake VA8000BWA Armour Super Tower - Black
Thermaltake PurePower Power Station 520W Modular ATX2.0 PSU
NEC ND4551 16x16 DVD±RW Dual Layer ReWriter (Black)
XFX GeForce 7800GT Extreme LED Edition 256MB GDDR3Western Digital Raptor 74GB WD740GD 10,000RPM SATA 8MB
I get a signal through my TFT if I connect to the top card but not the bottom. I have connected all the power cables required on to the MB and I have flashed the BIOS to the latest rev but am now pulling out my hair to get any ideas to why this doesn't work.
PLEASE HELP
