Thanks for your quick reply and for clearing this up for me.

One other thing, is the max ram speed type that my system can support PC3-10600

(1333MHz)? Or is it backwards compatible with higher speeds, i.e.  PC3-12800??

The reason I ask is that the higher speed one is much more widely available to purchase and even cheaper than the slower one,

The product I am looking to purchase is:

8GB Kit ($GBx") DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V

Can you tell me if that would be compatible with my system?

Thanks again for your help so far.
