RAM compatibility with Motherboard + CPU

Hello,

This is my first time building a high end PC and i just want to clarify some questions in regards to RAM compatibility.

Below are the components that i want to buy and I have also based my RAM decisions on these parts:
*CPU - Intel Core i7-4930k processor
*Motherboard - Asus RAMPAGE IV Black Edition

On the specification provided by the official website for these components it says memory type for the CPU is "DDR3-1333/1600/1866". As for the motherboard it says "8 x DIMM, Max. 64GB, DDR3 2800(O.C.)/2666(O.C.)/2400(O.C.)/2133(O.C.)/1866/1600/1333/1066 MHz Non-ECC"

If i were to buy a Corsair Vengeance Pro Red DDR3 PC19200/2400MHz CL11 4x8GB would this work on it's full potential or must i do something additional to get it working 100%.

The reason why i was considering 2400MHz over 1866MHz which im sure would be 100% compatible is because the price is actually the same where i am living (New Zealand).

Thanks in advance for any tips and advise, i really appreciate the time.

Cheers,
Fellow Gamer

You can use this RAM with default settings and it will operate at DDR3-1866 speeds.
To run at the higher speed, it is necessary to over clock the CPU memory bus.
With four memory channels running at DDR3-1866, you already have more memory bandwidth than the CPU will ever need.
You will notice no performance improvement by over clocking to higher memory bus speeds.

After my own current issues I would like to add to be sure you have all the memory you are going to want in this purchase. Get the 8x8gb kit now if there is a possibility and you can afford it. Mixing matched memory kits is proving to be a pile of trouble this go around. and I really wish I had spent the extra $10 for either a 4x4gb or a 2x8gb kit.

Compatibility is a valid issue, but the kit he is looking at is 4x8GB = 32GB.
This is more than he will ever possibly need in the lifetime of this computer.
Even a 4x4GB kit (16GB) would be enough.

Thank you so much for the confirmation on the RAM compatibility. I think i will stick with the 1866MHz as everyone is saying similar things around 1600MHz + RAMS having no evident performance gain for gaming currently.
