Cant do spaced 2way SLI on Evga E758 3XSLI mobo - Page 2

post #11 of 12
Interesting.

I was all set to tell you that board doesn't support dual-SLI in the top and bottom slots (the third only does SLI when the top two are full). In fact I'm 99% sure that board didn't use to allow it ... must've been a bios update, or you've discovered some secret trick to making it work in the order of doing things.

I remember because I was looking at that board at one point, and I was specifically told dual-sli didn't work in 1st and 3rd slot. I think even the manual might say it

Out of curiousity, do you have something else plugged in to the middle PCI-Ex 16x slot?

I am not running anything but the 2 gpu's. I have ran in slot 1 and 2 before also with nothing in the third, its just hotter. Now you must have misunderstood it will only run both cards @ x16 in 1 and 2. It will sli in 1 and 3 but @ x16/x8, a good oc and having 2 cards makes up for any loss in performance @ x8. If I remember correctly you need a 480 or bigger to come close to using all the bandwidth @ x8 anyway.
