[Simply Computers] Re: Difference in RAM memory

 

The numbers indicate the speed that the memory operates at.

Here's a quote from the Crucial FAQs:

"Though DDR2 memory was designed to be backward-compatible (meaning you can use PC2-5300 module in a computer designed to use PC2-4200, or vice-versa), we always recommend that you use the Crucial Memory Advisor tool to find exactly the right memory for your computer"

So, yes, it should work. (Note that I said "should")
