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.

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.

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.

Appears to be a driver issue?  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.

No one?

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.

E-mailed AMD tech support probably almost a week ago but no reply yet.

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/[email protected] so it doesn't seem to be the card.  Looks like I might have to try a fresh install of Windows?
