Formula VII and Corsair memory

[GGHOOST]

Hi everyone

I am soon going to but parts for my gamer pc.

I was on corsair's website and used the memory finder.

I do not have the formula VII on the list, but when i choose Formula VI, it do not show the Vengeance Pro memory.

Are they not compatible ? I was going to buy 16 GB kit 2400 Mhz i red. :confused:

And What is best:

2400 Mhz with CL11 or 1600 Mhz with CL9 ?

I am using Corsair Vengeance PRO 16GB 2400MHZ DDR3 (2x8GB) - CMY16GX3M2A2400C11 in my M7F.

Works perfectly.

Whatever memory you buy just make sure to buy one single kit of whatever size you want/need.

Vengeance pro will work fine.

G.Skill Trident X is great on those boards too and there are some fast kits.

Yeah, choosing a frequency is sometimes complicated a bit by the timings of the RAM. There is a formula that can help you in deciding if one kit is faster than the other when the timings are taken into account.

(CAS/frequency) x 2000 gives you a number in nanoseconds for comparing speeds.

Say you see a 1600 kit at 7-8-7-20 and a 1866 kit at 9-10-9-28 which is faster?
Well 7/1600 x 2000 = 8.75 nanoseconds; 9/1866 x 2000 = 9.646 so the 1600 kit actually looks quicker.

If these numbers are close or the same choose the higher frequency it will be more efficient.

In your case the 2400 C11 gives 9.17ns and the 1600 C9 gives 11.25...the 2400 kit is much quicker.

This even faster http://www.newegg.com/Product/Product.aspx?Item=N82E16820231589 😄

What do you mean by single kit? 1x16GB instead of 2x8GB? :confused:

For example: A single 16GB (2x8GB) kit instead of two 8GB (2x4GB) kits.

Okay, i was already going to buy 2x8GB 😉
