Abit KN9 SLI

Memory Performance:

The KN9 SLI memory performance is very strong, performing almost as well as MSI's nForce 570 SLI implementation and within the top three we've compared it against. The latency also isn't too bad averaging at 79 nanoseconds.

Disk Performance:

The USB 2.0 tests were done using an ATA133 160GB Maxtor DiamondMax 10 hard drive (model number: 6L160PO) using the same 8MB zone test enclosed in an Icy Box USB 2.0 hard drive caddy. We recorded the average read speeds and CPU usage.


Whilst the scores look good we had some trouble getting consistent results. It seems some USB ports on the rear I/O panel perform better than others. The top-most two perform about 4MB/s faster than the lower two when we diagnosed the problems we were having. We can't find any reason for this, despite the fact the CPU usage remained a consistent 3% and there are no BIOS options or motherboard jumpers to differentiate between them.
