Ram speeds on laptops

[ride3k]

If my memory is at 400mhz, does that mean i have to buy 400mhz memory? or if i buy a faster memory it will down clock itself to work with my laptop?

i think so, but i am not positive.

I wouldn't rely on it reverting to a slower speed. If the memory is not supported by your mobo it may not even boot. Generally if you have two supported speeds it will operate at the slower speed, but not always.

If you had DDR266, and you bought DDR400, the DDR400 would downclock to match the DDR266's speed.

Technically it should clock down the the correct speed. However, so many times I have tired say PC133 RAM in a PC100 system and it wouldn't work...

DDR400 is so common, I doubt you'd be able to find anything else faster for less. Not unless it's DDR2, which won't work in your laptop.

DDR2 is cheaper, and even though they have the same number of pins, you cant switch between the two.
