Take a look at all the similar postings in this forum first ... lots of options ... do you want to take apart completely your machine and how much experience do you have in tackling complicated upgrades?
Hi, i buy a G75 with 8 g ram 2 ram DDR 3 1600, now a buy 2 extra ram kingston DDR3 KVR 1333 s9 to have 16 .

Try similar spec RAM modules and see how that works.
Go buy 2 DDR3-1600 modules and determine how well it works. Win 7 Home Premium only uses up to 16 GB of RAM, so you will have to upgrade the OS in order to use all that. Unless you need 24 GB, 4x4 GB (16 GB) is likely to be more compatible and less trouble-prone. If you need more than that, disassemble the computer and upgrade to 4x8 (32) GB.

Looks like it is CL 9 ( latency ) most of us have CL 11 1600 installed ... put some kind of diagnostic tool into your current machine and check out the current memory for a match.
If you combine CL9 with CL11 it will have a mismatch and may run at a lower speed.
Should just run at CAS 11 in that case. RAM is pretty good about lowest-common-denominator defaults for compatibility...performance takes a hit, though.

Several reports in this forum where people putting in Corsair CL 9 along with stock ram no longer run at 800 dual channel after upgrade.
I think you are too optimistic here ... important to carefully check out your specs of your current hardware if not pulling out all the existing memory and double check for compatibility.
