Crossfire Tags: Radeon Crossfire MSI Graphics Last response: January 15, 2010 5:11 AM in Graphics & Displays Share spinnizle January 13, 2010 10:40:46 PM ive got the msi p55-gd55 its got two x16 slots one runs at x16 and the other at x4 do you think i can crossfire two 5770's just one on a x4 interface More about : crossfire bystander January 13, 2010 11:28:29 PM You probably could. Read this artical: http://www.tomshardware.com/reviews/p55-pci-express-sca... Essentially, with two 5870's, running at x4, you lose performance, but two 5870's running at x8 hardly are effected. Two 5770's are about the same speed as one 5870. Things might not scale exactly so simply, there is some reason to believe they would perform ok. m 0 l Maziar January 14, 2010 8:28:00 AM Yes you can run but as bystander said,with 4x you will lose performance,dual 8x and dual 16x are good options but 16x4x performs worse than both and isn't recommended for CrossFiring m 0 l Related resources 7870 xt crossfire - Forum R7 260X CrossFire - Forum Can i crossfire it ? - Forum Crossfire Vram usage increases - Forum Nvidia and AMD single card and SLI/Crossfire 3 monitors - Forum Can't find your answer ?

It's crossfire, right? the faster card will downclocked at the same speed with the slower... could u tell me more, guys? I'm still noob here... m 0 l Maziar January 14, 2010 1:04:14 PM http://www.msi.com/index.php?func=proddesc&maincat_no=1... • 1 PCI Express gen2 x16 slot (PCI_E2) • 1 PCI Express gen1 x16 slot supports x4 speed (PCI_E5) So i think if you run in CF mode,one will operate at 16x and the other one at 4x m 0 l wa1 January 14, 2010 1:08:56 PM okay, thanks for the info Maz... learned a lot... m 0 l Maziar January 15, 2010 5:11:58 AM No problem,i was a little confused too m 0 l Can't find your answer ?
