Home made 3-Way SLI results

[Sampsa]

Hi everyone,

Since NVIDIA's European PR department is not very interested of Nordic hardware sites (or overclockers) we naturally didn't get any chance to test 3-Way SLI system or even got hold of the 3-Way SLI bridge (not to mention lack of nForce 780i SLI samples etc). This situation has been continuing already over a years for us with every NVIDIA product launch

Anyway, since there was no support from NVIDIA, I had to make my own GHETTO-STYLE 3-Way SLI configuration:



First I checked my SLI-bridge situation... it was good with different length of bridges.





Next I installed bridges to three GeForce 8800 Ultras on EVGA nForce 680i SLI board. (One of the boards was Leadtek's watercooled Leviathan so I mounted 8800 GTX cooler on it).


Using Windows Vista, ForceWare 169.25 beta-drivers, Intel Core 2 Extreme QX6850 and Silverstone OP-1200W PSU I managed to get 3-Way SLI working properly



3DMark03 score with Single GeForce 8800 Ultra: 42273



3DMark03 score with two GeForce 8800 Ultras in SLI: 63061 (+49% compared to single card result)



3DMark03 score with three GeForce 8800 Ultras in 3-Way SLI: 72614 (+71% compared to single card result and +15% compared to SLI result)



I'll continue my testing during the weekend. Since I don't have nF780i SLI board I'll have to stick with QX6850 and nF680i SLI
