Today enabled 3-way SLI with three videocards on non-legal motherboard using HALmod 0.9 and slistring on Win7 X64.

Rig:

Intel SLBJH CPU
ASUS Maximus III Formula P55 chipset. SLI isn't working on in legally on 190/191 drivers.
2x1GB DDR3 DRAMs
Three GeForce 8800 Ultra
Enermax Revolution 85+ 1250W
Xtremelabs.org chiller for CPU



Middle card was not hooked to liquid tubing, just brief testing without any 3D here.



It works
Will perform performance tests these holidays.
