While the 6570 supports crossfire the Optiplex 990 Motherboard IS NOT a AMD CrossFireX Ready motherboard.ĪMD CrossFireX™ technology requires an AMD CrossFireX Ready motherboard, an AMD CrossFireX™ Bridge Interconnect "Ģ) Which makes little sense to me, why do I need a 6670 to run 6570 in a cross fire? Surely I should be able to use the same graphic card for it. Note that AMD CrossFireX technology in greater than dual mode is not supported with AMD Radeon™ HD 6570 graphics products. They claim "The operation of AMD CrossFireX™ technology in dual mode requires a second AMD Radeon™ HD 6670 graphics card and an AMD CrossFireX Ready motherboard. The wording on AMD Radeon site is not very clear. It seems AMD Radeon™ HD 6570 is the next bigger one and still available as Low Profile, which should fit in the OptiPlex 990 (SSF).ġ) What I am more interested in is if I could use Cross fire by buying two of these graphic cards and run them on 240Watt? Has anyone tried that? So I was thinking why not using a bigger graphic card like 6570 instead? Obviously the first limitation is that it needs also to be a low profile graphic card. According to Dell specs , the Small Form Factor Advanced provides 240 Watt.Īccording to the Radeon 64 both use only 144 Watt. ![]()
