Just a quick question

Would 3200 memory and 2100 work together?

I don't know of any incompatability issues with any 3200 memory combined with 2100 memory, but why would you want to do this anyway? Your pc-3200 memory will be limited to whatever speeds that your pc-2100 can attain.

Thanks for your reply pal , i will just get 2x 3200 sticks , does it matter if they r different makes?
