3-Way SLI with hack?

post #1 of 9
Thread Starter 
Guys, I have a quick question:

My board supports 2-Way SLI [sigrig] and I'm currently using 2 GTX 275s on it. It does have a 3rd PCI-e slot so will the SLI hack work for 3-Way SLI on my board or it doesn't work that way?

Thanks

you in theory would prob be able to run 3 way sli with no modifications or anything, but your 3rd slot if its like my boatd runs in x4 mode.. which is to low for it to really make any difference. if you want tri-sli you need something with a nforce200 chip

Won't the third card run only at 4x PCIE speed? That would net quite some performance loss and tri sli scaling isnt that great from the start....

I thought theres not much difference between 16x to 8x or 4x, only 1x is really worse?

Well I'm running on 8x and there isnt much loss but I remember reading that 4x is about 15% slower

I'm running on 8x as well and the loss is minimal. I remember seeing an article about single-gpu comparison of PCI-e bandwidth. the loss between 16x to 8x was ~1fps, 16x to 4x was about ~7fps, 16x to 1x was about ~20+ fps. I suppose it's not the same with SLI is it?

the 3rd slot routes through the sb and wont be detected for SLI, or in this case the nb.

Well SLI depends on bandwidth a bit more but I cant really say for sure maybe someone with more experience will tell you more

Now that's something nobody ever told me. Will the hack be useless as well?
