I'm having some problems with this board and our PCI hardware. The board is in a 2U chassis and the PCI riser board has 3x PCI-X slots sharing 133mhz and 2x PCIe sharing 2x8 bandwidth.
In the PCIe slots we have a USB 3.0 1x card and an eSATA 1x card.
In the PCI-X slots we have a 66mhz high end video capture card, which probably has about 128mb memory onboard, I can't find the exact specification anywhere.
Using this configuration and allocating 1.5GB of our 4GB RAM to the I/O Allocation in the BIOS (although using the PAE switch in XP makes this redundant from what I can tell) the system boots and we can capture video to our heart's content.
This is all well and good but the onboard graphics is rubbish and won't drive our 1920x1200 screen so we inserted a PCI Nvidia 8400GS 512MB graphics card, now I assume this video card operates at 33mhz, even if it ran at 66mhz we should still have enough bandwidth.
The computer boots fine with the setup but as soon as we try to capture any video the system drops frames and won't capture anything, which leads me to believe the graphics card is using up the bandwidth needed for the capture card.
The 2 cards are in the top and middle slot of the riser card, we tried the top and bottom but this had the same effect.
Anyone have any ideas?
