VIA RAID sharing IRQ and DV

[jeremic]

I have P4P800 delux motherboard with the on-board VIA RAID controller. Two HDD's are paired into one RAID 0 area and one HDD is on the IDE controler as stand allone. In the device manager, I see that the VIA RAID controller is sharing the IRQ with the PCI BUS. This apperantly should not affect the speed of the HDD's in the RAID. However, the Sandra benchmarking software shows that the RAID area is much slower than the independend drive. At the same time, I can not use the RAID HDD's for caputing/exporting digital video files to the camcorder, which is an indication of the insuficient speed. I suspect that the IRQ sharing is responsible for this. Does anyone knows something about the problem. How could I free up one IRQ and dedicate it to VIA RAID? I am running Windows XP Home SP1. Thank you.

IRQ sharing is probably not your problem (it rarely ever is, if ever these days). More likely the onboard RAID is flooding the bandwidth of your PCI bus/IDE channel.

Thanks for your response. Is there anything what I could do to solve the problem and to speed up the RAID configuration? Thanks,
