    What are the differences between the 5400 and 5300? Both are listed at 667. I was going to upgrade my ASUS A8JP from 1GB to 2GB. Will either of these types of RAM work with my laptop?

    Both PC2-5300 and PC2-5400 run at the same speeds in standard laptops. Certain manufacturers like to label their products using different methods. The both run at 667mhz. The multiplier is 8. So 667 X 8 = 5336. So its a toss up between what that should rounded to for naming purposes, 5300 or 5400?

    I did read on some review website that Corsair names their modules 5400 because they actually test them at 675mhz (675 x 8 = 5400). I dunno if all manufacturers use the same higher guidelines for testing before calling their chips 5400.

    The corsair difference should not matter to you unless you are interested in overclocking your ram, then it might sway your decision on which brand to buy. For standard users, they both run at 667mhz and one should be able to mix-n-match between "5300" and "5400"

    Hope this helps

    There's zero difference between the chips - manufacturers calculate the designation number differently due to rounding. That number is calculated by multiplying the clockspeed of the RAM by 8, so 667 * 8 = 5336. Some manufacturers round up, others down - that's why you are seeing different numbers. PC5300 is more commonly used.
