Athlon 64 benchmark help

[hwstock]

Would you help me by running a benchmark on AMD64 systems with
dual-channel DDR?

I am trying to decide on getting an Athlon 64 or a P4 (875 or 865xx)
dual-channel PC3200 system. Most of the machine's CPU cycles will be
used to run just one program, which happens to be very memory-intensive.
This benchmark is a scaled-down version of that particular program, with a
realistic calculation load.

Some representative results so far:
3.2-year-old 1.4 GHz P4 with PC800 RDRAM -- 5.54 MUPs (higher is better)

Mobile AMD AthlonT 64 3000+ Processor (1.8 GHz) w/ 1Mb L2 cache and 512Mb
PC2700 (SINGLE CHANNEL!!) -- 6.68 MUPs
(this is why I'm so interested in testing a dual-channel system)

P4 i3.3 GHz 222 MHz FSB 4x256 mb OCZ 3700 2-3-3-5 -- 8.67 MUPs

...I'd really, really like to see what a DUAL CHANNEL athlon 64 FX 51 or 53
will do.
=====the test========
First, this is the same benchmark I posted here at least 2 years ago... but
hardware has changed a lot since then.

Here are some rather dated, painfully explicit instructions for running the
test under windows. The file is in Microsoft Word format. The Linux version
is very similar in usage, except the switches in the "bat" file are
explicitly placed after the executable name at the command prompt.

Instructions for benchmark

...If you try to open this file directly from the web, and you have
NortonAntivirus, you may get a complaint that this file has a "malicious
script" (it doesn't), probably because it has embedded web URLs. In any
case, you may want to download the file and scan it before you read it.

And here are the zipped benchmark executables, for windows (95 and up) and
Linux x86.

Just post the MUPs rating (and unique run number), found either on the screen printout, or at the end ofthe lb_data.txt file.

Athlon 64 3000+ is clocked at 2.0 ghz and only has 512 k's of L2 cache.

?? I'm a little puzzled about this comment -- do you have results for a 2.0 GHz Athlon 64 ??

This benchmark is not greatly affected by the size of the L2 cache (in fact, a really large cache can slow it down slightly). The raw ability of the CPU to get data in from main memory is very important. I'm hoping that the built-in memory controller of the athlon 64 FX 5x series, and dual-channel ram, give a significant performance advantage over the single-channel athlon 64 results above. (Though I don't know the limit -- for memory bandwidth -- built into the chip.)
