680i and the three PCI-E slots

post #1 of 4
Thread Starter 
As you are probably aware, most 680i boards have 3 PCI-E x16 slots, two are truly 16x and one is 16x but powered only by 8x architecture. It was originally intended for physiX cards and the like.

I was wondering if anyone knows of some benchmarks testing the performance impact of 8800GTX SLI while using the 8x slot and one of the 16x slots, instead of using both the 16x slots.

Any help appreciated.

Hi ane welcome to the forum.Nice rig.I try yesterday to run sli in my board,for some benches.And i end using the 2nd slot the x8 instead of the 3rth slot.Due to my cooler in the sb,is no room to fit the 2nd card in the bottom slot.Even was small card the 6800gs and don't fit with some aftermarket coolers.And i installed and run the benches,but in the end im sure it affect my scores.Anyways that's why they made the board with 3 slot's.Some day im goin to remove my cooler in the sb,and run the same benches with the same card to find out.But i can tell you is goin to affect your benches no your gamming.
Just my 2 cents.

The board will only run sli from the top and bottom slot. You can run a video card off the centre slot (8x or 16x not withstanding) but not in conjunction with sli.
