RightMark
Even though we don't have a database of results to compare to, I decided to add RightMark memory benchmarks to this review in order to better show the maximum possible read and write speeds, as well as determine the actual latency.
At stock, we got 8.38GB/sec reads, and when overclocked, we got almost 10GB/sec read speeds! Granted, that was with extremely good memory.

Write performance was also quite good, 7.46GB/sec at stock, rising to 8.58GB when overclocked.

There is NOTHING out there that compares to the on-chip memory controller on Athlon processors... just look at those latency figures! We got as low as 21.4ns when overclocked, and a still extremely impressive 25.6ns at stock!

Combining read, write and latency tests, the overall bandwidth is just shy of 4GB/sec at stock, and reaches 4.6GB/sec overclocked.
Sandra
We have a good database of Sandra results, and the K9N does very well.
At stock speeds, the K9N led the field - and also at overclocked speeds. The BIOS settings that are not user changeable must be set to fairly aggressive values for such excellent memory performance.
