You need to eliminate the operating system and background tasks
from your measurements. Get a copy of memtest86 from www.memtest.org .
It is a memory test program, but it has a "bandwidth" indicator in
the upper left hand corner of the screen.
Memtest86 will format a blank floppy for you. You set the floppy in
your boot order, and the computer will boot from the memtest86
prepared floppy. The screen of the computer will run in 640x480
mode and display memory information, including the progress of
the test. Just pop the floppy and press esc to terminate the
test and reboot the computer. With the floppy removed, you'll
boot back to your hard drive.
Memtest has three bandwidth indicators, and the third one (smallest
value) is the measurement of main memory. I get 2955MB/sec with
version 1.40 of memtest86+ .
I also ran Everest Version 1.10.106 and the memory benchmarks are:
Memory Read 5360MB/sec
Memory Write 2341MB/sec
My system:
2.8Ghz/FSB800/512KB Northwood stock speed
2x512MB Ballistix PC3200
System settings:
AI Overclock Tuner [Standard]
Performance Mode [Standard] (I think this helps get PAT)
Hyperthreading Technology [Enabled]
Configure DRAM Timing by SPD [Disabled]
(memory set to 2-2-2-6-4)
Performance Accelerate Mode [Enabled]
DRAM Idle Timer [Auto]
DRAM Refresh Rate [Auto]
PCI Latency Timer [64] (I think that is the default)
Another check for your system is to run CTIAW:
ftp://ftp.heise.de/pub/ct/ctsi/ctiaw.zip
It runs in a command (MSDOS) window. It will report the
state of PAT as "(1) Fully Enabled" , if all the conditions
have been met for PAT. You can also verify the rest of your
stats.
For PAT to be enabled, generally it helps to have Performance Mode
set to Standard, use a CAS2 memory (not sure if CAS3 memory
will report as PAT enabled), and if using four sticks of memory,
stick with stock speed (FSB800, DDR400).
Your performance numbers are far enough off, that perhaps your
FSB isn't set correctly, or maybe you are using a Mobile
processor ? A Pentium 4 Mobile processor, no matter what speed
grade, will start up in a desktop motherboard running at
1.2GHz FSB400. You have to set the FSB manually to get the
performance out of it.
So, the key right now:
Get a copy of memtest86+ 1.40 and compare to 2955MB/sec
That is with CAS2 memory in dual channel mode, and a 2.8GHz proc.
By using memtest86, you'll remove the effects of the OS and
applications. I run Win2K and have absolutely no protection
applications (no antivirus, no spyware detection, etc) on this
computer. (Because it isn't my surf computer and isn't used
that much.)
