1.5GBps is 187Mbytes/sec. Which sounds low. I know can ring out 300MBytes/sec or
2.4GBps on one of our RAMBUS systems.

I was under the impression that you could actually wring out about 1.5GBps
out the theoretical 3.2GBps max of a dual-channel PC800 RDRAM set-up. Not
sure if this applies for both writes and reads though.
