Hello, first time writing in this forum :) ..

I have HP Elitebook 2570P (i7 3520M, 4 GB Ram (pretty sure its 1600 MHZ DDR 3 based on this:

[in this link they talk about the version with the i5.. and im with i7 so im not sure its same ram but probably it does..]

so i can add 4GB ram stick of Kingston DDR 3 1600 MHz or a G.Skill 2133 Mhz..
im not sure if its possible to mix diffrent kind of speed sticks, and if my motherboard and cpu can even support this speed..?

can u please help me..?

Thanks, Adar.
