Which P67 MB for 2 GTx275's SLI?

post #1 of 11
Thread Starter 
I used to have a working EVGA 750i SLI FTW. One of the GTX275 was always running about 15-20 degrees C hotter.
Will a UD4 MB have more separation that the 750i?
Which MB would you recommend with a i5 2500k and 2 GTX275's?

750i FTW is double spaced just like P67 boards.

Yes I know.....but is there more room between the two cards in a ud4 or would i have to get a ud7? I think a ud7 board uses the pci-e lane 1 and 4 if a 2 sli configuration is used. But paying that much for just that is kind of crazy.

There will be 1 pci slot of space between the gpu's on the UD4 when running SLI/Xfire. I'm not sure about the UD7...Click to see Gigabyte P67A UD7 manual so you can do the research

UD7 is only 1 slot spacing because of the ability to TRI-SLI

Red indicates where the GPUs go.

solution:
turn up fans
add a 120mm fan on the case door blowing cool air onto cards.
buy EVGA 275 backplate

fixed!
having one space is fine! right now i dont have any free space on my mobo since i have three dual slot cards in. btw i took off the case door. REALLY improves temps

Thanks lost-boi. Nice comparison. +Rep!

I assume the ud4 is the same as the ud5, pci-e wise.

Looking at the spacing, the 750i actually has the best spacing of the all.

Same spacing as the UD5.
Its double spacing because there are two other connectors between the PCI-E 16 lanes.
The 750i has two PCI lanes and the UD5 has a PCI and a PCI-E 1x lane.

Solution, watercool those buggers. My GPUs idle at 38c and load to about 46c in game.
