Okay so I have 2x 4GB sticks of RAM on an "ASRock H61M-S" motherboard with an i5 2500k processor.
Dont laugh at me but how many RAM slots does this motherboard have?
I've heard some have 4 slots so could I chuck another 2x 4GB sticks of RAM in?
If it only has 2 slots, can you get 2x 8GB?

And last but not least, how the heck do I go about installing it myself if I do purchase more? (Comp. technitians cost too much lol)

Thanks for any help.

Oh and this is the RAM I have:
