As far as I see, since mod was released 99.99% of all instability reported here is caused by non-stable overclock, flawy videocards, PSU or another hardware problem. Check every component in detail. SLI mod just fools ID for driver, it's doing NOTHING to SLI tech or driver routines. It's all there as was made by nvidia. And now, Good news! Forceware driver 195.62 WHQL succesfully patched now by our master Sveetsnelda. This time Windows Vista/7 32-bit version. Test rig: QX9650 ASUS P5B DLX (P965 chipset) 2 x 8800Ultra Win7 32bit RTM build 7600, with just only SLIC patched in registry by SLIstringinstall v2.0 Even no test mode , no need for that for 32bit. We will release mod public soon.
