Asus P4C800E deluxe capacity problem

Hi all. I've assembled a system using the following
componets.
Intel P4 3.2(retail HS).
CPU temp checked and not high.
Asus P4C800E-Deluxe MB(bios 1.019)
2 times 1 gig dimm's (kraton 3200U CL 3)(total of two gigs)
Case edge case with a 430watt PS
One 160 gig SATA segate HD.
Nivida Geforce 6800 GT(on its on power connector, and not sharing a
IRQ).using the 66.93 drivers from Nvida's site.
Sound blaster Audigy 2(drivers from site)
Plextor DvDr drive (Px712A).
Windows XP pro, SP2.
Now all of this works...Posted fine and no
trouble there...But when I run benchmarks and
applications, I'm seeing a serious bottle neck
in capacity. I have the dimms installed in dual mode
(slot one and slot three). The dimms have been checked,
and they are 3200's. They post as 400mhz dual channel
linear mode. When I run Sandra 2004 I'm seeing only 37-41%
capacity in terms of memory bandwidth. The Aquarmark score
is 27,040. Future mark 05 is 2754. Future mark 03 is 8521.
I've tried everything I can think of to no avail. Does anyone
have any experience in dealing with this problem? MANY
thanks in advance.

What exactly are your sandra memory bandwith readings ?

My P4C800ED, with a 3 GHz Prescott CPU and 2x512MB of dual-channel
CL 2.5 DDR400 ECC RAM:
Sandra reports BW = ~4.5 GB/s (and, correctly, 6.4 GB/s peak).
Everest, which I like better than Sandra, reports ~5.2/1.7 GB/s for
read/write BW.

Just downloaded and ran Everest HE.

First - turn on PAT , it seems to be disabled.

Wow - that's horrible.

Just to check - DIMMs in slots 1 and 3 means using the blue sockets,
which works for me.

When you run Everest, make sure no other apps are running, since Everest
must compete for memory BW (and for CPU cycles) which will surely hurt
the reported BW. For example, when I run a couple of FP-intensive apps
with Everest, the reported memory BW goes down by ~25%, and those apps
are not memory-intensive.

(Sorry if this reply appears twice - my ISP's news server is flakey.)
 
Just for curiousity, I ran Everest on my P4C800E Deluxe to see what mine
measured at.

Mine's only a 2.8gig with 512 of generic DDR400 ram (in the blue sockets)
that I thru together just to have a system I could use for trying new
software/hardware on for experimenting.
(BIOS 1120 beta)

nothing fancy at all, just a mediocore system to play with..
All stock settings, no attempt at OC'ing at all.

Just double checked...They are both in the blue slots. When
I run it, nothing is running in the background.I have TDS3(most
recent data base) AVG pro7(most recent data base) spybot
search and destroy, ad aware, and scan spyware(all the
most recent versions). I also have sysgate pro firewall,
and I use the firefox browser. I've checked for malware
processes...Nothing. I was hoping that someone out there
had some idea how to proceed. Many thanks for your time
and effort.

try each of the DIMMs separately to rule out as bad stick of memory

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.)

HTH,
Paul
