ASUS A7N8X-E Deluxe.............Memory problems/questions

[Wildbill]

When I ordered my system, I ordered PC3200 DDR400 memory. I have
posted here before about my puter being so slow, but have not come to
any conclusions yet.

I have run both AIDA32 and FreshDiagnose, and could not find any
problems until I was going over the reports again today. I found that
I have PC3200 memory installed, but it only runs at 200MHz. Could this
be the culprit?

Thanks in advance for your input and advice!

There are many things that can make a computer slow.

What are you finding slow on the machine ? Windows desktop slow to
render, files slow to open, or what ? Game framerate slow ?
You need to give us more symptoms, otherwise we'd be forced to
give you a "laundry list" of things to check.

DDR memory takes the 200MHz clock you give it, and it will
transfer data at 400 million transfers a second (two transfer
per clock cycle). They call that DDR400 for double data rate.
Since 8 bytes are transferred each time, 8*DDR400=PC3200 MB/sec.

So, either tell us what feels slow, or give us meanful benchmarks,
or dump the parts of AIDA32 that have slow looking numbers.

A computer can be slow because of:

1) Underclocked processor core.
2) Disks running in PIO, rather than DMA mode.
3) "Delayed Transaction" [Disabled] in the BIOS
4) "PCI Latency" [32] is normal, less than 16 spells trouble
5) Runaway tasks sucking up most of the CPU.
6) Intel processor overheated, and running in "thermal throttle" mode.

The list goes on and on.

For the video card:

7) AGP slot in PCI mode (missing chipset driver)
8) AGP video chip underclocked with "tuner app"
9) Video card shares physical interrupt signal with another high
interrupt rate PCI device.

To see where your video card sits, benchmark-wise, try something like:

Nope. That is how it should show. The RAM operates at 200 MHz which is
equal to a Dual Data Rate(DDR) of 400 MHz, AKA PC3200. Are you running
your 2800+ at a FSB of 166 MHz and Multiplier at 12.5? You will get the
best performance from your memory by running it, in sync, at 166 Mhz as
well. HTH.

Just got an e-mail from computer manufacturer. They have determined
that the memory installed is not compatable with the A7N8X-E Deluxe
motherboard. They are sending new memory.

Thanks for the help guys/gals

i have a7n8x-e deluxe bios 1008 athlon xp 3000+ 400 mhz and viking
pc3200 (2 x 512 mb)and don't work and i try the best performance and
buy 2 corsair xms low letacy dual channel pc3200 400mhz and testes in
200 mhz dual channel and my firend that is a imitation of concord
airplane jet if you run soo fast and take out a real speed of your cpu
and your mobo buy a corsair xms
now if you have a lot money buy the pro version have led light and the
regular version work anymor is the same thing with led light
