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

External Since: Feb 02, 2004 Posts: 6

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)
Cool

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:
