Crossfire problem

[Morg]

Hello,

I've bought a HIS ICE-Q 7950 to crossfire with my MSI Twin Forzr 7950 and have been unable to get Windows to boot. I've tried each card separately and they work fine. I've uninstalled all drivers prior to installation. Is there a way to test if the second PCIE slot is causing the problem or any other suggestions? Here's the rest of the specs.

i5 2500k at 4.3
16gb Corsair Blue (2x8)
Gigabyte GA-Z68XP-UD4
Corsair TX850 bronze power supply

Thanks

I had similar trouble when I bought the MSI HD 7950 Twin Frozr III Boost Edition. I installed it into the first PCIE slot and ran it by itself for a couple of days first to check it was working okay, had no problems so installed a Gigabyte Windforce 7950 in the second PCIE slot and straight away started getting overheating problems from the MSI card.

After checking both cards on their own again for a day or two I reinstalled both for crossfire, this time the Gigabyte in slot 1, MSI in slot 2 and they've worked fine since, apart from Firefox not liking hardware acceleration with crossfire running.

Tried seeing if your Motherboard has BIOS update?

I've the latest non uefi bios, the uefi bios seems to be an after thought by gigabyte in that you lose the overclocking options. I'll try booting with just a card in the slower of the pcie slots and see what happens. Is it a common problem to be able to post but windows not boot?

Thanks for your suggestions by the way
