New Ram, please help

[aaronjunited]

Im struggling to pick ram for my new build.

Im getting the AsRock Z68 Extreme4 Gen3 mobo along with an I5 2500K.
I have looked at ram, now I dont know what to pick.

Obviously it has to be DDR3.
Which "memory speed" and which "memory speed mhz" should i be going with?
Also which module, channel, pins and socket do I need.

Never used to be so many different things I had to check to pick ram.

Also which will give me best performance for gaming? and 8gb or 16gb???


Thanks lads.

thanks for that answer, super.

So would I use 8gb of ram, if not would the extra 4gb do anything for me at all?

these ok??
