motherboard DFI NF4 SLI-DR
video card: Leadtek 6800 gt sli pack
cpu:amd 64 3200+ venice
I've already exclude the problem of win xp (fresh install), virus (fresh install without network) and drivers (official driver)
Here is my situation:
1. install just one video card in pci-e slot 1 and set jumper to single vga mode.
In windows xp device manager, it says this card uses pci slot 6 (pci bus 5 and
irq is 18. Under this set up, there is a high cpu usage problem. When I use some software to check, it says it is a hardware interrupt which pccupise cpu.
2. install just one video card in pci-e slot 4 and set jumper to single vga mode.
In windows xp device manager, it says this card uses pci slot 9 (pci bus 2 and
irq is 17.
3. install both cards in pci-e slot 1 and 4 and set jumper to sli mode. it says that the one in pcie 1 is in pci slot 7(pci bus 4, irq 19) and the other one in pcie 4 is in pci slot 6(pci bus 5, irq 18) . Same cpu problem appears. And if I disable the card in pci shlot 6 (irq 8), which is in the pci-e slot 4, problem disappears.
Now anybody knows if this is a hardware problem? In single mode, both cards work well in pci-e slot 4 but not in pci-e slot 1. And in sli mode, the one in pci-e slot 1 works well but not the one in pci-e slot 4.
Should I RMA the video cards or motherboard?
