Oh Hai! Finally got it. After headache after headache (rma's mostly), I did it. Triple SLi is now enable on my machine. I want to give everyone a run down on what I've learned from this, and what Ive gotten from it, considering I know not many have tried it. First off, the heat is absolutely ridiculous (as Im sure anyone could have guessed). I was expecting this, and I overcompensated on the water loop I configured for this. Best pump, great radiator (dual), and plenty of (quiet) airflow over the rad. Wasnt enough. I had to insert a triple radiator into the loop WITH the dual, and its STILL warming up on me (its manageable though,,, until I can think of something to do about it). Second, despite the best of my efforts, I cannot get 3dmark06 to finish a test with it. Its not overheating, and it appears to be a driver issue which is weird considering games work just dandy. Thirdly, it IS possible to do this without water cooling. I tested the system beforehand with air cooling to make sure everything was ok, and the temps were actually pretty acceptable (about 70c at the most under load), but that was with lots of air being rushed through the case. And last the not least,,, performance (minus 3dmark of course :wanker I was expecting a performance increase, of course, why would I have even tried this otherwise? What I got was a mind blowing increase in framerate. From what I see in the first couple tests in 3dmark06 before it stops, is a 150% increase from a single gtx, literally. With one card I get about 80fps on the first part of the first test (the dudes helmets in the transport with the red glow), with two I got 100fps, and with three i get 130fps. The part where the soldiers are shooting at each other I would get about 25fps with a single card, 45fps with 2 cards, and 60fps with three. Crysis now runs at 40fps with everything max and AA at 2x. Before I could max about half the settings and no AA at 35-40fps. Thats the only game worth mentioning considering COD4 and others are easily maxed out with even one gtx. I hope this is helpful to someone, or at least interesting. I wasnt expecting what I have now as far as performance, but now I need to address this heat issue, case looks hilarious with this triple rad stickin out the side of it.
