Has anyone tried a Tri-Sli with 3 GTX 295's?

**Airbrushkid** · 07-05-09, 07:57 AM

Just wondering if someone did the tri-sli with 3 gtx 295's that be wild as hell. Just think 6 gpu's!

i dont doubt that its possublee to do from an engineering standfpoint (with current hardware), but youd be looking at up to a 6 frame delay and(well actually more is possible) and the software isn't there. CPU overhead would grow somewhat too, so for many games you'd notice a sizeable decrease (when load blanching wouldn't bring enough gains.

Who cares about the delay. Imagine the folding horsepower

Um it wouldn't be Tri-SLi with 3 295GTX since each is already SLi... that would be Six-SLi which I don't think is supported... only Quad SLi (Two 295 GTX).

You cant Tri SLi 295s...it would be one bad a$$ rig if you could.

You can only connect one SLI bridge to the GTX 295 so quad SLI is the maximum.

6-way SLI is not supported in the drivers, however, you could use it for folding.

Thank you for the replies guys. It would be sick if you could do 6 way sli.

Working for Cyberpower System we have experimented with it, 3 way SLI will not work and folding on a 3 way SLI board will also mean much much lower performance. We found on a X48 board or a Crossfire board Folding performance is almost doubled. one of the cards dual GPU's will refuse to work correctly on SLI motherboards. Just a word of advice, as we build high end gaming systems and folding systems for medial research and data centres.

You don't need to use the bridge for SLI. It will result in lower performance though.

Um, that would be six-way, not three-way.

I would imagine that if nvidia supports 3 295's it would still be a bottleneck in an overclocked i7 platform. A few reviews with dual 295's and 3X285 tests confirm that they are still the bottleneck (rather than cpu limitations) when it comes to high resolution max AA/AF Crysis testing.
