For those of you asking about memory, Project 640 uses Crucial's

Ballistix. It's Crucial's attempt at overclocking memory --and it works.

The P5AD2-E Premium motherboard supports DDR2 711, which

doesn't exist. Crucial's PC 2-5300 fills the bill with a little playroom.

(By the way, three weeks ago, it was $328 per 1GB.)
