I have not tested the x99 classified in almost 2 years now, but I trust Corsair Dominator ram. I bought a 2400mhz kit, and it has a 2400 mhz xmp as well as a 2666mhz xmp profile. That made it very easy to set it and forget it.

These are in my X99 Classy build
 
G.SKILL Ripjaws 4 Series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Desktop Memory Model F4-3000C15Q-16GRR

In general, with most of our boards from X79 Dark and newer, I recommend G Skill.  I had had consistently good luck with their memory, fast, reliable, and with the exception of their HIGH end kits, are pretty inexpensive.  Also if you stay around 2666 then you will not need to worry about the memories XMP profile overclocking your CPU via BCLK either.

3200 MHz doesn't require OCing the CPU or BCLK on the X99 Classified, yet 2800, 3000, and anything higher (to the best of my knowledge) than 3200 will.

I have 32Gb of this http://www.evga.com/Products/Product.aspx?pn=16G-D4-2800-MR and yes you have to bump up your BCLK to run them at their rated speed. Has not been an issue for my cpu. Actually need less multiplier for your cpu oc with a bumped up BCLK. Of course Micro Center only and much cheaper then what EVGA has them listed at. http://www.microcenter.com/product/456796/16GB_DDR4-2800_(PC4-22400)_CL16_Desktop_Memory_Kit_(Four_x_4GB_Memory_Modules)
 

Old quote is...old, but since we're necro'ing the thread (which technically isn't against the TOS, btw), I'll answer it.

Thank you Sajin. Looks like the 16gb is showing dual channel though. But I do like those...

Website must be wrong as dual channel kits come in pairs. You get four dimms with the 16GB kit.

Kind of curious about this, as Gskill site shows Dual channel as well. What do you think? http://www.gskill.com/en/product/f4-3000c15q-16gvr

Looks like their site is wrong also. I'm running this kit and it shows it's quad channel. Notice the capacity between both kits are 4GBx4.

My assumption is because those kits (or, at least, the ones notfordman linked from the g.skill website) were developed for the Z170 platform, and it's just a matched kit of the normal dual-channel memory for the Z170's.  If you look at the QVL, they only list Z170 boards.  On the flip side, the last set Sajin linked, the QVL is only for Gigabyte X99 boards, which would, presumably, be labeled for Quad-channel compatibility.  In other words, promoting the memory as dual-channel or quad-channel does not necessarily depend on the number of sticks in the kit.
 
For practical purposes, however, it should only matter the platform/CPU and how many sticks you have when it comes to whether you run sticks in dual-channel or quad-channel.

I think GSkill Trident Z are newer and maybe better modules than in CORSAIR Dominator Platinum.
My recommendation, this kit is QVL for Rampage V Edition 10th
 
F4-3200C14Q-32GTZ  14-14-14
 
This is QVL for EVGA X99 and Rampage series as well
 
F4-3200C14Q-32GTZSW 14-14-14
 
Both for Broadwell-EX.
But 70% of IMC not support so fast memory.
And Broadwell-EX and Haswell-EX.
 
 
I think something... 16GB is enough for gaming PC for now?
I suppose 32GB is overkill.
