I just added another ATI HD 5770 card and am having issues with my display when I enable Crossfire. NO problems with basic desktop stuff (surf internet etc.), just when I play Starcraft 2. When starting up SC2, I get squiggly/blurry display. Sometimes, if I move the mouse, it stops but comes back a couple of seconds. But for the most part, it's consistently blurry screen.
I noticed that my sapphire has connections for two bridges and my MSI 5770 hawk has 1 connection for 1 bridge. Could this be my problem?
I have the latest Catalyst drivers from AMD's website as of 1/17/2012.
Here is my configuration:
AMD Phenom II X4 925 Processor 2.8 Ghz
8GB of RAM
Windows 7 64-bit Service Pack 1
ASUS M4A79XTD EVO AM3 AMD 790X ATX AMD Motherboard
SAPPHIRE Vapor-X 100283VX-2L Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card w/ Eyefinity
MSI R5770 Hawk 1GB
Any help would be greatly appreciated.
