If looking at CPU-Z or similar and it shows 800 - that's the TRUE freq, but this is DDR (DOUBLE data rate) so take TRUE freq of 800 times 2 to get effective rate - here you have 1600
If you have "800mhz" ram right now, that would likely be DDR2. The Cosair DDR3 1600 ram you are talking about would be faster, but your motherboard likely would only support DDR2 RAM, not DDR3.
Is it ddr2 or ddr3 RAM? There is now 1600MHz ram for ddr2. If it's ddr3, don't get confused by tools like cpu-z. It shows the real 800MHz clock. 1600Mhz is only made from "double data rate" (2*800) by marketing people.

my ram is definitely ddr3 i think im getting mixed up with mhz and ghz i think im looking at the wrong thing
