actionstan Posted August 30, 2009 Posted August 30, 2009 i see some motherboards that cut the pcie bandwidth from x16 to x8 when ran in crossfire and to x4 in trifire.. isnt that sorta besides the point? or is the lower bandwidth not a big loss with multiple gpus even though they cant run at full potential, and is every motherboard that supports multi gpu this way or just older ones?

rourkchris Posted August 30, 2009 Posted August 30, 2009 It varies from chipset to chipset. I have an older(bought over 1 1/2 ago) X38 motherboard and it has 2 full PCI-E @ 16x. On a P45 chipset motherboard with one @16x and one @ 8x you can't tell the difference at all. Share this post Link to post Share on other sites More sharing options...
slick2500 Posted August 30, 2009 Posted August 30, 2009 AFIK most current cards don't even come close to maxing out the 8X PCI-E slot. Share this post Link to post Share on other sites More sharing options...

Hyper Posted September 4, 2009 Posted September 4, 2009 thats scary.. how did u kill one... >.> I liquid cooled them and the top card sprung a leak.... I must have wiggled something loose after leak testing.. after that I switched from clamps to compression fittings.. not a problem since Share this post Link to post Share on other sites More sharing options...
