32GB Low Profile memory kit?

Hello guys I have a question. I know I might have asked this before but I think I should ask it in a clearer way.
On the ASUS P8Z68-V/GEN3 motherboard there are 4 memory slots. The board itself can hold up to 32GB of ram.
However, the heat sink used on the board is a Noctua NH-D14 (the big one) so the only way to use all 4 slots is to have low profile memory.
My question is the following:
Does a set of 32GB 1600MHZ or over Low Profile exist?
I have searched and I am yet to find anything like this.
I love Corsair but unfortunately their 32 GB kit is only in the high profile.
It has to be 4x8GB. The motherboard is dual channel so it does not matter if the memory is quad channel or not so long as it is the same memory it will work in 2x dual channel.
So what I would like to know is
Does a kit exist of
4x8GB 1600MHZ or higher
or sticks of 1x8GB 1600MHZ or higher

Remember it must be low profile otherwise it will not fix on the motherboard.

Thanks in advance!

G.SKILL Ripjaws X Series 32GB (4 x 8GB) DDR3 1600 F3-12800CL10Q-32GBXL - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

G.SKILL Ripjaws Z Series 32GB (4 x 8GB) DDR3 1600 F3-12800CL10Q-32GBZL - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

They'll both fit and are DDR3-1600, "Quad channel kit for Intel X79 LGA 2011" means zip - they'll both work; see -> http://noctua.at/main.php?show=compatibility_ram_gen&pr... then search Ripjaws X or Ripjaws Z.

Fantastic! Those will work.
What is the difference between the Z and X series? The only difference I can see the Z series is designed for LGA 2011 and XMP 1.3 Ready
Would the Z series work on a Z68 motherboard?
Is there any difference between the X and Z series at all?
Also one more question: Is it worth it getting faster memory? 1600+ MHZ memory? Are there any 32GB kits that are faster memory?
Would I see that much of a difference?

The board is a Asus P8Z68-V Pro/Gen 3 and the CPU is an Intel I7 2600+
(Sorry I wrote V Gen 3 it is a V pro I dont think it makes a difference though)

I haven't looked at all the JEDEC CAS Timings of both Kits, I just know the XMP. Both kits have identical ratings of DDR3-1600 10-10-10-30 @ 1.50v.

On a P67/Z68 LGA 1155 there very little benefits from >DDR3-1600. Yes there are DDR3-1866 but the cost is exponentially high (double) and IMO a total waste.

As it is, DDR3-1600 CAS 10 for 8GB/stick is very fast. My concerns with today's lithography is faster would generate more errors. There's a huge difference from R/W data on 2GB vs 4GB vs 8GB density IC's, think of it like a forest. On my servers DDR3-1333 8GB/stick ECC is as fast (today) as I care to go; faster garbage vs slightly slower error free.

Ok fair enough!
What is XMP is it something I would rather have on my memory over not have?
Considering everything else is the same should I get the X or Z series?
(Forgive me I just read what XMP is and it seems to be extreme memory profile for overclockers)
I guess this would be something that i can save in my motherboard that auto sets the ram to specific settings?

XMP is Intel's form of 'SPD' it has Frequency/CAS/Voltage information encoded on the RAM more less same as JEDEC, but limited to Intel platform only. I always set my RAM manually so I don't rely on SPD/XMP on the PC's I build. XMP is useless for overclockers, XMP encodes Rated only -- if I OC the RAM e.g. DDR3-1600 Rated to DDR3-1800 XMP would stop me.

On a single fully matched kit XMP works fine, except often on Gigabyte, and where XMP can mess things up is with multiple kits or other mix-matching of RAM.

Further, keep in mind if you simply stick in a set of DDR3-1600 under Auto aka Default it's going to run DDR3-1333. In the case of ASUS its pretty simple:

AI Overlcock Tuner -> XMP
DRAM OC Profile -> DDR3-1600MHz
Save and your done. :)

edit: BTW when you look at CPU-z you'll see your DDR3-1600 listed as 'DRAM Frequency = 800MHz' this is correct. DDR = Double Data Rate; data is being pushed on the top and bottom of the Sine wave or twice in one pass.

So I got my memory today and I am super excited to slap it in.
Just for fun though I am curious to know if G.Skill (or any other company for that matter) make a set of memory that fits the Noctua NH-D14 that is 4x8GB 2133MHZ
I checked G.Skill site and they only have 8x4GB @2133MHZ
