Can i mix Different Mhz Ram together?

Can i mix 3 PC2-5300 (333 Mhz) with 1 PC2-3200 (200 Mhz)
Or it will slow down my pc?
Answer #1
as far as i know you can, but the 333mhz will only run at 200mhz.
Answer #2
In theory they should work OK but both at 200Mhz..
Also they would not be able to work in dual channel mode.

thanks for reply
