Corsair Vengeance Pro 16GB 1866mhz vs 2400mhz (GA-Z97X-Gaming G1 WIFI-BK)

[Fazzyy]

Hi All,

I am new to computer builds and needed some advice, sorry if the answer is obvious.

I have GA-Z97X-Gaming G1 WIFI-BK, i7 4790k, Corsair H100iGTX, but just deciding on the ram.

First of all is this ram compatible?
'Vengeance® Pro Series — 16GB (2 x 8GB) DDR3 DRAM 2400MHz C11 Memory Kit (CMY16GX3M2A2400C11R)'

Also, I can get the following two for virtually the same price, 2400Mhz is slightly cheaper but didn't want to get a higher speed ram if it may cause some instability.

Vengeance® Pro Series — 16GB (2 x 8GB) DDR3 DRAM 2400MHz C11 Memory Kit (CMY16GX3M2A2400C11R)

Vengeance® Pro Series — 16GB (2 x 8GB) DDR3 DRAM 1866MHz C9 Memory Kit (CMY16GX3M2A1866C9R)

Would really appreciate any advice.

The 2400 sticks will be fine, it may require a slight OC of the CPU to run at 2400 (very slight maybe 4.2 at most). Think you'll be happier with the 2400 for the extra bandwidth

Thank you, what if I want to underclock the ram to 1866mhz or 1600mhz with cl9. Is this possible?

Yes, and can tighten the timing to get near same performance, if any problems give me a holler (or a PM )

Thank you so much!!

In this link http://www.corsair.com/en-gb/vengeance-pro-series-16gb-2-x-8gb-ddr3-dram-1866mhz-c9-memory-kit-cmy16gx3m2a1866c9r under the technical specs is says the timings for their 1866mhz is 9-10-9-27 with a voltage of 1.5v.

Is this the settings I need to use?

That would be a good starter, then could try 9-9-9-25/6 and maybe tighter
