I finally got around to "trying" SLI on my D901C, but with a catch, i'm using a 9800m GTX and a Quadro FX3700m from an HP and even more so, I don't have another D901C heatsink, so I am using a D900F heatsink.
I copied the VBIOS from my 9800m GTX and flashed it to my FX3700m, all was good, BIOS shows 2 GPU's that match
got into windows, installed drivers, all good, enabled SLI, all good, it boots up warning me the bridge is missing(as expected) so next i wen to run games... it's really...
