Can't get Tri or Quad crossfire to work...

alkusoittow · 11-03-09, 10:46 AM

First of all, Hello! I'm new to the forum and probably have a lot of learning to do... I just built my first rig from the ground up, which has been a huge upgrade from my old HP A1430N (AMD 3800+ 2.0GHz 64x2, 2GB DDR 400, plus other crappy specs...)

To start, here's my setup:

AMD Phenom II 955
ASUS M4A79 Deluxe
8GB DDR2 800 RAM
ATI HD Radeon 3650 x 4 (working on the crossfire thing now...)
4 x HDD, in 2 RAID 0 arrays
Apevia X-Telestar Mid-tower
Zalman 92mm CPU cooler
ASUS 22" LCD
Windows 7 64-bit

So, I can get 2 cards to go into crossfire mode, but not all 4, or even 3 for that matter. I'm totally stumped. I've deleted and re-installed all the ATI drivers, CCC, etc. I currently am running DirectX 11, have all the Windows 7 updates, etc... When I enable crossfire, that little dropdown menu shows up where you select the configuration (which cards, which lanes, etc) but it only gives me 2 options, and both options say 2 GPUs, never 3 or 4...

Any help with this would be greatly appreciated! I'm ready to get this beast going!

Here's some screenshots of my situation:

And some shots of the system:

Can you post up a pic of how the cards are bridged together inside your computer?

Yes definitely, I will take a picture as soon as I get home from work (around 5pm, PST)

Cool... oh and

I take it in GPUz at the bottom tab it does show all 4 GPUs?

As a matter of fact, it does show all 4 GPU's... Same in Device Manager. The computer can see all 4, but can't get em to work together...
