Title: [SOLVED] Windows 7 Crashes Immediately After Logging In (with 3rd 5970) Post by: someone703 on March 08, 2012, 01:57:35 AM Hope someone could shed some light.
Just got my Sapphire RMA back and it appears to be good to go. Shouldn't be a power issue as my AX1200 should be more than enough. Tried uninstalling Catalyst Control Center and SDK2.1 and restarted with all 3 cards in. The 2 Diamonds have been working fine for the past month or 2. Installed the Sapphire by itself and it works fine. Any combination of 2 cards (Diamond1+Diamond2; Sapphire+Diamond1; Sapphire+Diamond2) works just fine. It's when I have all 3 going that my system acts up. I've noticed too that when I have only 2 with the PCI-E power connectors plugged in, when the system is turned on the fans kick in immediately and are very audible. When I try with 3, the system sounds more silent as if the GPU fans aren't going (at a high speed at least). Booting into Safe Mode and logging in works just fine. Device Manager doesn't show any issues with the cards or drivers under Display Adapters. Edit: Mining with the Sapphire and one Diamond at the moment and it appears stable at 825/150@1.049v so it doesn't seem to be the card. Looks like I might have to try a fresh install of Windows?

Seem to have a good number of views lol... Will give a BTC to anyone that helps me figure this out. Reformatting did nothing. Same as before. Safe mode is fine. Getting into Windows restarts comp without a bluescreen. Booting up with 2 now doesn't kick the fans in real loud right away. Must've been Catalyst Control Center doing that. Appears to be a driver issue? Will going to an older version of Catalyst help? E-mailed AMD tech support probably almost a week ago but no reply yet.

Will going to an older version of Catalyst help? Ummm... you wouldn't be using a 32-bit version of Windows? x86 Windows is limited to 4 GPUs, you know. That's only two 5970 cards.Else try out a few Catalyst versions, by all means - I'm surprised you haven't done that already. Title: Re: Windows 7 Crashes Immediately After Logging In (with 3rd 5970) Post by: casascius on March 10, 2012, 06:23:06 AM I thought the 32 bit thing too. I had 32 bit Ubuntu and this exact same problem putting the third 5970 on a board, which went away when I switched to 64 bit.
Title: Re: Windows 7 Crashes Immediately After Logging In (with 3rd 5970) Post by: someone703 on March 10, 2012, 09:19:14 AM Yea I'm running 64-bit Windows.
Guess I'll try to message the other people running 3x5970s and see what version of Catalyst they're on. Title: Re: Windows 7 Crashes Immediately After Logging In (with 3rd 5970) Post by: portron on March 10, 2012, 09:24:50 AM Revert to 11.12 Drivers
Anything after that has a bug that crashes with 4+ GPU's.

This appears to have worked like a charm. Address you'd like me to send the BTC to? Now to see what kinda ridiculous temps I hit while mining and it it's stable.
