STREAM from http://www.cs.virginia.edu/stream/ (scroll down to heading
"PC-compatible Results" for a link to download the Linux binary).

BTW, that MemSpeed test is easy to run. I'd appreciate hearing what other
people are getting out of it.

I guess, but not because I want it to!

On the AMIBIOS "CPU PnP Setup Page" I've got the CPU Speed set to 100 and
the DRAM Frequency set to 133. (That should give my speed before "doubling"
if I understand it.) On the "Advanced Setup Page" I've tried setting the
SDR/DDR CAS Latency to SPD, 2T and 2.5T. Changes to those values give me
slight changes in speed, but nothing more.

I've left some other settings alone, but maybe one of them *should* change.
DRAM Timing Configuration is Normal, SDR/DDR RAS Active Time is 6T, SDR/DDR
RAS Precharge Time is 4T, and Auto Detect DIM/PCI Clk is ACTIVE.
