I have recently had a problem with my system crashing, and showing an error of missing or corrupt C:\WINDOWS\SYSTEM32\CONFIG\SYSTEM file. The manufaturer determined this to be an error with the motherboard or memory, and has replaced this with am updated motherboard.

I originally had 512MB DDR-266 RAM, which I then updated with another 512MB of similar spec RAM approximately six months before the fault. This additional RAM was bought from the manufacturer.

The new motherboard supports 333-DDR memory and the manufacturer provided a replacement for the original RAM (512MB DDR-333) but said that the additional RAM was not covered by warranty. I was then left with a 512MB memory module that couldn't be used.

I then reset the BIOS to operate the bus at 266MHz and plugged in the additional RAM module and all appears fine. The question is:

Am I better off having 512MB of memory operating at 333MHz or 1GB memory operating at 266MHz?

Part of the reason for wanting to install the memory was to check if it was the additional memory that was faulty in which case the manufacturer should be responsible for changing it?

Any clues as to the best approach?

You'll get better system performance using 512MB of 333mhz RAM. The only exceptions would be video editing, and a few of the newer games with very large texture maps.

You could still install the additional memory, run it at 266mhz and test with http://www.memtest86.com to see if it's defective.
