Hey guys having trouble getting both cards to boot, I am running two GTX 570HD 1.5GB on a Rampage IV Extreme. Got everything else working on the MB, but I have to disable the secondary card via a motherboard switch to get to the system to boot. However if I disable my primary card and boot off the second it works perfectly fine too, just not both together.
Doesn't crash or anything, all seems to load fine during PCI Configuration etc however once it gets to the Ethernet script right before it typically boots it freezes up permanently.
Another point I noticed is that during the initial -v code on bootup both cards are recognized correctly, however the second card displays a memory value of -4060MB? However when booted in standalone it displays correctly..
Could anybody point me in the right direction?
Ive tried various boot flags to no avail...
currently booting on npci=0x2000 and PCIRootUID=0 GraphicsEnabler=Yes
Thanks a bunch
