I bought a Dell Dimension e521 w/1gb dual channel 667 (according to the order form) though the manual says "533-MHz, 667-MHz, 800-MHz (when available) DDR2 SDRAM". My questions are:
1. As I shop on various websites (like Crucial.com), shouldn't I try to get the 667 that the order form says I have inside the machine?
2. If I currently have a dual channel system with four total slots, two currently used with a 2x512 config @ 667, is it a good idea to upgrade my current 1gb to 3 total (using all four slots for a total of 3gb of dual channel: 512x2 + 1gx2)?
3. What difference does the memory timing make? I see 3-3-3-12 vs CL=5 (see below).
CT587625 DDR2 PC2-5300 • 3-3-3-12 • UNBUFFERED • NON-ECC • DDR2-667 • 2.2V • 128Meg x 64
CT587631 DDR2 PC2-5300 • CL=5 • UNBUFFERED • NON-ECC • DDR2-667 • 1.8V • 128Meg x 64
4. Finally, Is there any noticable difference between Vista Home Premium with 2gb vs 3gb? If not, then I'll got the cheaper route and get just 1gb (512x2) for a total of 2gb.
