First of all, my specs.
CPU: i5 3350P
GPU: Asus GeForce 760GTX
RAM: 3x 2Gb Kingston Kingston HyperX Fury Blue 1600 Mhz
MBo: Asus P8Z77-V LX

Why does CPU-z says that my ram works on 800 Mhz, when they should be 1600Mhz models?
I suppose that system raises clock speeds when it is necessary.

I want to purchase either 2x 4Gb or a single 8 GB RAM from the same manufacturer and type, but currently the only available for purchase have latency of 10 or lower, and my current one is 11 I think. (I have no idea how much of impact do they have on performance).

My Mobo has 4 slots and 3 of them are currently occupied. So, what is best for me to do considering this situation? Will everything go without problems even when they have different latencies and sizes? Will they be able to run in dual(quad?) channel?

Thank you and please excuse my poor English and technical knowledge.

Best is to buy a set of the full amount of DRAM you want, trying to 'ADD' more DRAM offers no guarantees what you buy will play with what you already have, the forums are full of people trying to add new to their old and problem after problem, would either go with a 2x4GB and see if a couple of the old will play or just get 2x8GB and sell all the old
