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

That's what oc'ing is all about, awesome Sampsa

Nice looking good so far ,,, But The more cards you use the slower the GT1

[Soakki]

nice pictures!

In my opinion 3-Way SLI with 8800 Ultra's isn't anywhere near ghetto-style :-D

Ahh looking good is seen it have real performance after 3way-SLI

nice Sampsa

btw. ah can overclock GFX on 3 SLI ? Thanks

Guys in case you din't notice but GT3 is overhoaling GT4 LOL???

What's wrong with that. It's normal in 03??

Nice going there Sampsa Waiting those OC results.

normal ? dunno

[SF3D]

normal ? dunno

With Nvidia cards GT3 is better than GT4

Top CF results are like newbeetles 89K result. CF is more effective in DX9 I quess and that's why Nature is better than GT3.

could be yes
that's why i asked

[SamHughe]

See and that's why Sampsa should include some real world gaming results like Crysis, CoD4 etc. Cause SLIed ultras normally perform better than CFed 2900s in games.

Man 3GHz 72k is nice

[NH|Delph1]

Nice one sampsa

The home made bridge really makes it all worthwhile.

And by the way, XFX has an office in Sweden now. I'll pass their info on to you.

Stock cooling overclocking:



3DMark03: 82531

QX6580 @ 3,6 GHz
Ultras 650/1150

More coming

[blind_ripper]

now thats really geto

[Sampsa]

CPU @ 4,7 GHz should give ~100k..

Nice results Sampsa! What mobo?

[nachthymnen]

That's super!
Fantastic work Sampsa!

Nice results Sampsa! What mobo?

EVGA nForce680i SLI

[RAW-Raptor22]

Works on 680i? Sweetness.

[Mean Machine]

Nice going, Sampsa.

[Spacehead]

Great!

The fact that they limited this to only GTX's/Ultras is gonna KILL the appeal of 3 way SLi. They could easily produce a bridge that has a middle connector for the 8800's that dont have 2 SLi conections on each card. They NEED to do this.

Maybe it is a bandwidth issue? Maybe later? Anyway, I think GeForce 8800 GT 3-Way SLI configuration would be very attractive
