    PC2-5300 or PC3-6400 RAM for x300?

    Hello,

    The x300 has a 800 MHz FSB and comes with PC2-5300 667 MHz RAM.

    Would the system be able to handle PC2-6400 800MHz RAM and would that be a worthwhile upgrade?

    By the way, what is the difference between PC2-5300 and PC2-5400 RAM - both are listed as 667 MHz?

    Is it safe to assume that the system would not be able to take advantage of the new PC3 DDR memories (like PC3-8500 1066 MHz)?

    Thank you!

    DDR3 memory is a different form factor altogether I believe (someone correct me if I'm wrong). I'm running 4GB of PC2-5300 in my computer right now and get a 5.9 in WEI's memory score. Honestly I don't think you'll see much of a difference except in a benchmark.

    the X300's memory bus is limited to 667 MHz so anything faster (PC2-5400 or PC2-6400) will simply downclock to PC2-5300 speeds. buy whatever is the least expensive since all three will run at exactly the same speed, even in benchmarks.

    DDR3-8500 modules are have 204 pins (instead of 200 pins) and are not compatible with the X300.

    Erik,

    Why do you say the X300's FSB is limited to 667 MHz when the spec is listed as 800 MHz on Lenovo's site?

    Thanks.
