Hello, i'm in a urgent need of buying a memory ram for a friend's computer,
and i'm not sure what type of ram should i buy, if anybody could help, it would be very much appreciated.

The system currently has a single stick of a 4GB RAM running at 1866Mhz in single channel, it's a
Kingstone HyperX Red Fury.
i was thinking of buying another piece of ram to make it run in dual-channel if possible.

i' found 3 types of ram with different size, which i think would be compatible, the manufacturer is kingston, and all of 'em run at 1866 Mhz.

2 Sticks are HyperX Fury' series, but differ at the size, one has 4GB and the other one has 8GB
the third one is a Savage at 1866Mhz and is a 4GB Stick.

Here is the Mobo - GA-F2A85X-D3H - CPU A8 5600K - though i think he said that he going to update it's processor to 6800K

Update: I wanted to mention that the "Savage" has 'CL9' and the other two have 'CL10'
if that matters in some way.
Thank you

yes it matters. and while in theory they should be compatible it will depend on there jdec timings which are often very different even between ram from the same manufacturer.
buy ram thats in matched pairs for a dual channel system for best stability.

When you use dual channel system then same memory should be mounted in both channels. i've seen pc run dual channel with different memory but it is not recommended. So Hyper X 4GB would be the choice.
