Help needed for Z77

[famdevos]

Goodevening,

im looking for some help for memory modules to fit in on my board

Mobo: ASRock z77 extreme 4
CPU: Intel i5 3570k

Memory: i found 3 different sets to choose from which i want to build into my system;

G.Skill RipjawsZ 16GB DDR3-2133 CL9-11-10 quad kit F3-17000CL9Q-16GBZH (i know these fit since they are on QVL list mobo)

How about these 2 will they fit

G.Skill RipjawsZ 8GB DDR3-1600 CL8 kit F3-12800CL8Q-8GBZH

and

G.Skill RipjawsZ 8GB DDR3-2133 CL9 quad kit F3-17000CL9Q-8GBZH

and taken from these 3 sets if they would fit what would be the best choice to go with?

With the 3570K you'll prob want to OC, so I'd jump right to the 2133 sticks. If it's in the budget go ahead and get the 16GB set now so you have a single set that's tested to work together, if you go 8GB now and then decide to upgrade, another 8GB set might not want to play with the one you get now, and if thinking 2 *gb sets now, that can be problematic, not to mention XMP won't work with mixed sets (even of the same model. So my suggestion would be the Ripjaws Z 16 GB/CL9 you selected or might even take a look at the 2133/CL9 Snipers F3-17000CL9Q-16GBSR or 2133/CL9 Ares F3-2133C9Q-16GAB, all would be good choices for the CPU/mobo combo

I think you'll be happy with them have a good night, wish the weather here was a bit cooler like yours is, suppose to hit right at a 100 today.
