Im looking for someone that has bought one, or would know for sure. I cant seem to find a lot on my motherboard. Looked on the RAM site and they havnt updated thier compatible page in like 2 years.

Motherboard only lists a few ram types and I know it can take others.

Im living in Belgium right now so Im limited on the computer parts I can buy. RAM seems to be a really bad problem.

Thanks for your help.

Also as a side question, is it better for a gamer to have DDR2-800 with CL5, or DDR2-667 with CL4?

Thanks.
