both are compatiable... work in my P4... 256MB each.... but is one of them restricting me from OCing better? and if they are compatiable.. are the speeds the same? thanks! and can anyone lead me to a good site that sells RAM at cheap prices... thanks
Technically any DDR RAM should work with one-another. However, any SD RAM should as well, yet I've seen PC100 laptops that won't accept PC133 RAM It all really depends on the computer.
