Probably, but who cares, it's not like he'll be running the system as his normal 24/7 use. Besides that he's kept his CPU and RAM on a 1:1 ratio up to like 330MHz (DDR2660) So I don't believe theres a bottleneck between the RAM. As far as the L2 cache goes, it's built into the chip and is always communicating at the same speed so I doubt there's a bottleneck there either.
