2 of the 4 SATA cables packaged with the K8W were intermittent bad 
(SCSI/DMA errors, BIOS didn't see them at boot).  New cables, no problem.

No I don't work for AMD or Tyan :)  I tried the K8W as a high throughput 
client driver platform because I couldnt take the budget hit on an Iwill 
QK8S which we use in production...they work like perfect screaming daemons.

Also considered the MSI board but no numa memory interconnect and no 64bit 
slots.

Good luck.
