I wasn't sure where to post this as I don't know if it's a driver problem or possibly a PSU. I recently swapped my Sapphire HD4850 for a Sapphire HD4870 X2 and I just can't get it to run stable. When I swapped cards I uninstalled the ATI drivers and the CCC and ran Driver Sweeper in safe mode first. I installed the card then 8.11 software. All was well until I rebooted. Now this happens every time: Following a reboot CCC shows the crossfire tab and crossfire is ticked. If I right mouse click on the CCC it shows 3 graphics cards instead of 2 all being ATI Radeon HD 4870 X2's. When I look under display manager it shows 3 not 2 possible displays for some reason. There is only one monitor shown under graphics adapter.
I've installed 8.12 drivers but the problem persists.
I reinstalled Vista x64 reformatting the drive. The same problem occurs then I noticed something very obvious. This only happens on a cold boot. I can reboot the PC as often as I want once I've resolved the multiple display problem by disabling them in CCC and the problem does not reoccur. If I shut the PC down and leave it off a while the problem comes back. So that's the obvious bit, but I'm still no wiser why this is happening. MY PSU should be enough. Here's my complete system:
Does that sound enough for the PSU?
None of these problems occurred with my Sapphire HD 4850 and have only arisen after installing the Sapphire HD 4870 X2. I've also flashed my mobo with the latest 1202 bios but nothing has changed.
If it is the PSU what would people recommend as a suitable replacement?
Cheers
