I have the following hardware:
EPOX EP-8RDA3+ mobo
AMD XP-1500 cpu
2 X 512MB non-parity non-ecc memory PC2100 sdrams
1 X Maxtor 40GB HDD
1 X Maxtor 80GB HDD
1 X ASUS DVD rom
1 X LG CD-RW

I am running windows XP sp1 and all latest patches.

I have the following problem:
When I download files I often get CRC errors or file corrption, I then re-download and sometimes it is okay. I have even had MD5 checksum discrepencies when coping a file from a DVD onto my HDD. I copy the same file from the same DVD onto another machine also running Windows XP and the MD5 checksum is correct.

I have tried doing scandisks and an load of ather diagnostic tool checks but found nothing. I even reformated my disks and re-installed XP with no joy.

Sounds like you have ram that is noisy or failing. If you can, try to replace the ram and see if that helps.

You have to order ECC registered ram, it is quite abit more expensive. One thing that you could check with is try removing one of the ram sticks, do the symptoms change? This would help narrow the problem down. If you have a diagnostic for your hard drive, I would run that also just to check. They are usually available from the manufactor site.

I thought that might be the case but it is new mem modules but that could still be a problem.
Sissoft Sandra recomends that I use ECC full Parity memory for memory larger than 512MB.
My mobo does not support ECC full Parity memory modules according to the mobo docs.
So the question then becomes what is the best memory to use?

I downloaded a memory testing tool called memt86 and it showed up loads of memory erros, so I tested my 2 mem odules 1 at a time. I found 1 to be faulty/noisey so I removed it and now everything is fine.
