[SOLVED] 8th GPU crashes "AMD External events viewer"

[rotrot]

I have been trying to get my miner set up but am having a problem with the last GPU.

I first tried using Windows 7 64-bit but couldnt get it to boot with more that 4 GPU's (2 5970's). It would freeze at the splash screen. So I installed Windows 8 developer preview and it recognizes and installs drivers for all 8 GPU's (4 5970's). No problems booting up at all.

Miners runs fine with three of the cards installed (6 GPU's). When I try and boot with the fourth card installed it crashes the "AMD external events viewer" every time. If I try and mine after this (external events viewer crash) the computer freezes up after a few seconds.

Has anyone experienced this error or have some ideas for a possible workaround?

My equipment is a Biostar TA-870 mobo with 4 reference 5970's. Windows 8 developer preview with corresponding windows 8 ati catalyst.

Solved. Re-installed Windows 8 w/ Catalyst 12.1 Preview Beta and everything is running smoothly. I have an 8 GPU machine deployed. Over 3 GH. yeah.
