I have been using XFX HD 6870 and decided to get another one to cross fire. I have been working all day, reformatting my computer, installing/deleting/reinstalling drives, just a very very frustrating day. Crossfire is supposed to be pretty simple to set up. This is just ridiculous. I have been looking at forums ALL day to find solutions to this, and all them lead to dead ends.
I have tried both the cards in the first pci-e slot (16x) and they both work fine. Neither will work in the second slot (4x). The fan will work, but my computer does not recognize the second device, and because of that ATI Control Center cant enable crossfire (the option does not exist).
Computer specs:
PSU: 750watt Thermaltake(crossfire support)
Motherboard: ASRock M3a770DE
Video cards: 2 XFX HD 6870
RAM: Ripsaw 8 GB 1600 (which is funny because they will only load at 1333...)
Processor: AMD X4 955
Windows 7 64 bit home edition
Bios version: 1.8
I am sorry for the frustration and angry post, but I have never been this frustrated working on a computer before.
