I've been banging my head against this for a day and thought I'd toss it out and see if anyone has any ideas. I have an old box that I'm putting 2 XFX Radeon 5850's in to mine with. Hardware specs are as follows:
- ECS P45T-A Motherboard
- Core 2 Duo e6600
- 4 GB Ram
- 2 x XFX Radeon 5850's
- A dummy plug with 68 Ohm resistors in each card
So I've installed Windows 7 Pro x64 and for the life of me I can't seem to get the Catalyst drivers, ATI Stream and MSI Afterburner to recognize the cards correctly. I've tried various versions of each, (Catalyst 11.4 & 11.5, ATI Stream 2.1 & 2.5 & Afterburner 2.1 and 2.2 Beta), yet no matter what I try, Catalyst Control Center won't open and MSI Afterbuner comes up seeing the card, but missing the driver and all other clock information.
I've tried installing the different applications in different orders (Cat, Stream, AB / Stream, Cat, AB, etc) and still no dice. Strangely, if I install Win 7 Home Premium x64, everything appears to work fine. Of course, I don't have a license key for that, only the Pro version. I've even tried Windows XP, but couldn't get it to enable both cards.
I may just have some drivers kludged up now, but DriverSweeper is no more, so I have to keep reinstalling the OS, which is painful with all the patches.
Anyone have any thoughts?
