Hi,
I recently upgraded my file server to a dual AMD 2800+ on a Tyan Tiger MPX motherboard. The previous server was using a PIII 700 on an Intel 440BX motherboard. I basically just took the IDE drives and their controllers across to the new machine. The strange thing is that the RAID-5 performance is worse than before! Have a look at the stats below:
Hi Marc,
Unfortunately you have a lemon :(
I spent some time trying to get acceptable performance out of an Adaptec SCSI RAID 0 on the 32 bit, 33MHz bus of one of these boards and eventually found this:

The executive summary is
"After testing AMD determined that the problem was identified as a bandwidth issue(this was startling information). It appears that the motherboard has a bandwidth limitation of 25MB/s on PCI devices that are connected through the AMD 768 Southbridge."
This was in line with my findings.
I have not tried, but it is possible that a 64 bit 66MHz IDE card will be OK.
