RAM DoA or incompatible?

[Account]

Trying to upgrade my old comp (very old) by adding an extra 1gb ram.
http://www.uktsupport.co.uk/advent/pc/t9201.htm

When I inserted the second one, it isn't detected.

On my old (512mb) one, it says:
PC3200U-30331-Z
512MB DDR PC3200 CL3

On my new (1gb) one, it says:
PC3200-R-30331-C0
1024MB DDR 400 CL3 ECC Reg

If I remove the 512mb and put the new one in, it gives a long beep (memory error).

I guess the problem is that it doesn't take ECC? But would that be the cause of the long beeps and failure to post?

Thanks.

Well that sucks I guess I can't return this either..

Thanks

Edit: But I heard that a non ecc mobo would still accept ecc, however it would turn off the ecc features, would that be the case?

Is it from OcUK Account or auction or another e-Vendor?

Unfortunately, it was from ebay and the seller only accepts doa items and replaces them.

I guess I could resell it or something.

Thanks.
