results intel OR840 dual rambus PC800-45

Dear Mr McCalpin,

please find enclosed my results on an intel OR840 dual CPU dual rambus channel Mobo. I used the downloadable binary for winNT wstream.exe

OS= MS w2k Server SP2,  single CPU kernel
CPU= 1x intel PIII coppermine 933MHz/133/256k L2 Cache
Main Memory= 2x 128MB Samsung PC800-45 RDRAM

D:\bench\STREAM_John_McCalpin\win32>wstream 933 20
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 999936
Total memory required = 24.9 MB.
Each test is run 20 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 23104 microseconds.
   (= 23104 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.

I tested this system also with William Henning's http://www.cpureview.com
MemTach V.093 where it performed quite poorer than an asus A7V133 1x Athlon 850, FSB100 using interleaved 2 DIMM's PC133-333 SDRAM.

In your STREAM bench the asus A7V133 scores:

Copy:  507 MB/s
Scale: 408 MB/s
Add:   355 MB/s
Triad: 307 MB/s

It's frustrating that the i840 chipset performs that worse, kind of a looser chipset against AMD 760MP(x) dual Athlon chipset which score around 1GB/s according to your website.

These results seem ridiculus against a NEX SX4 (16'000MB/s) or SX5 (42'000 MB/s)
