Which AMD Chipset? VIA did some pretty bad PCI implementations
in the past. Once I wondered about suspiciously low transfer
rates in the process of testing 3Ware and Adaptec (2120S, 2200S)
RAID-Controllers. The transfer rates maxed out at ca. 30 MByte/s.
Switching the testboxes mainboard from one with VIA chipset to
one with an AMD (MP / MPX) chipset was a great success.
