8 Gigs at 533 or 4 Gigs at 800? (DDR2)

Welcome to Tom's Forum! :) 

The Differences between Higher Frequency {Faster} + Higher CAS {Slower} vs Lower Frequency + Lower CAS are negligible; <1~3%. So it comes down to 4GB vs 8GB - Hmmm... YES the 8GB WINS!!! However, >4GB requires 64-bit OS.

Example - You have to look at RAM as a whole Frequency {bandwidth} and CAS {pauses} with their combined transmission. Think of is this way a car can instantly go 100 MPH but the Stops are longer (9 sec) vs 75 MPH but the stops are shorter (7 sec) both with a 100 stops in a mile. Further, the CPU however says you can run only 85 MPH.
