It Depends

Mate, it depends on your motherboard. Usually though on DDR memory its backward compatible so it will just run at the slowest speed e.g. 2100. You could go to www.crucial.com/uk and from there run the scan my PC - this will tell you exactly what you can and can't fit & mix etc - this is a free service. I've bought from Crucial and they have been excellent.

Hope this helps,
Cheers Keith.

DDR Ram doesn't have the problems of old Ram, you can mix sizes and speed as long as they are DDR (not DDR2) you should be fine.
The memory will clock down to work at the speed of the lowest.
