X1900 Crossfire + 975x motherboard users IRQ assignment

eva2000

Someone weird's happened on my 2nd badaxe rig, trying to enable Crossfire gives me a 0x0000007f BSOD.

I made sure to disable write combining and largesystemcache before installing and have no problems up to the point of loading CCC panel. But when i hit the 'enable crossfire' check box and hit okay, i get a BSOD

Tried 6.5, 6.6 and 6.7 drivers all the same.

This doesn't happen on my 1st badaxe rig but i didn't check the IRQ assignment on 1st badaxe rig. On the 2nd rig here's my IRQ assigment







Does this look right to you ? Badaxe board doesn't seem to have IRQ assignment options in bios ?

Anyone with crossfire setup on 975x board care to compare what their IRQ assignment is like ?

thanks

Its weird that a USB controller would share IRQ's with a graphics card...really weird

Same here, X800 sharing with USB and I have all 8 USB connectors full, don't know how much that hurts the GPU, if at all.
