Need a little help / advice on my newest gaming rig. I have built it myself with these specs:
i7 930 @ 4GHz
6GB DDR3 Patriot RAM
2 x ATI Radeon 5870 XXX Edition
Corsair 850W Modular PSU
2 x HDDs (250GB and 1TB)
A DVD Drive
6 x 120mm Case Fans
Windows 7 - 64 Bit
Latest ATI Drivers 10.5
I'm having alot of problems getting the graphics cards to perform correctly - at first they were artifacting, so I tested each card individually and they worked fine. But they don't want to work together - I have tried the basics:
-CrossFire Bridge is on
-Tried Dual Crossfire Bridges
The cards are really close together - and do get rather hot, peaking at roughly 78C which isn't bad at all. I managed to get them to boot in Crossfire, but it was artifacting on the Desktop - I managed to change the Memory and Core Clocks down to Minimum and ran Furmark for well over an hour without any problems - again peaking at 78C.
So what do you guys think the issue may be? A bigger PSU? If so, any recommendations?
