Ram for Asus P9X79 WS & i7 3030k G.Skill responds!

Question

Many of us have had difficulty finding high density ram kits that would be compatible with our planed systems.  I have included below my correspondence with the G.Skill Tech Support Team in hopes that it will shed some light on this issue:
Dear Sir:
Will the following Ram kits work with an Asus P9X79 WS LGA 2011 motherboard and Intel i7 3930k processor and Windows 7 Pro 64bit operating system?
G.SKILL Ripjaws Z Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL10Q-32GBZL
DDR3 1866 (PC3 14900)
Timing 10-11-10-30
Cas Latency 10
Voltage 1.5V
G.SKILL Ripjaws Z Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-2133C11Q-32GZL
DDR3 2133 (PC3 17000)
Timing 11-11-11-31
Cas Latency 11
Voltage 1.5V
Are there any other ram kits that you believe would be more compatible?
What about this ram kit:?
G.SKILL Ripjaws Z Series 64GB (8 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL11Q2-64GBZLD
DDR3 2133 (PC3 17000)
Timing 11-11-11-31
Cas Latency 11
Voltage 1.5V
I am planning on overclocking.  The computer will be used for video editing with Adobe Premiere Pro CS6. 
Will the faster ram kits, (2133 speed), provide a significant improvement?
Thank you much for any advice you can provide me with,
Wylin
Dear Customer Those are perfect kits for your motherboard and CPU. DDR3-2133 has a greater bandwidth, but it is necessary to overclock the CPU to fully take advantage. Thank you

Dear Wylin Tjoelker,
Your setup can go up to 2133MHz for DDR3 memory kits. However, since your purpose is for Premiere, a full 64GB would be a priority over frequency increase to 2133MHz. In other words, it is better to not run out of memory, than render a few seconds faster.
Regarding the differences between 1866MHz and 2133MHz, we would have to say not much. On artificial benchmarks, going from 1866MHz to 2133MHz result in about 3-5% performance increase. In real world scenarios, this would translate to only a few seconds difference of rendering.
We would recommend you to look into our 64GB at 1600MHz (F3-12800CL10Q2-64GBZL) if you’re looking to maximize your memory capacity while saving a little bit of cash. However, if price is not a problem, then you can consider our 64GB at 2133MHz (F3-17000CL11Q2-64GBZLD).
If you are considering 32GB, then any of our 1866MHz would be a good choice. 2133MHz’s performance increase may not justify the price increase.
Please do feel free to contact us again if you have any further questions. Thank you for choosing G.Skill!

Dear Tech Support Team,
Thank you much for your very complete and helpful response!
I searched for the more affordable 64GB kit "our 64GB at 1600MHz (F3-12800CL10Q2-64GBZL) " but have not been able to find it.  New Egg shows it as being "Discontinued" and out of stock.  Is it going to be replaced by a new model kit of 64GB 1600 or 1866MHz ?
If not then I will go with the 32GB 1866MHz kit: F3-14900CL10Q-32GBZL
Thanks so much and all the best to you,
Wylin Tjoelker
Dear Wylin Tjoelker,
We asked around for you. It seems like all our F3-12800CL10Q2-64GBZL memory kits in stock have all been sold out, ordered by various retailers around the world, and would require some time to manufacture a fresh stock of the memory kits. At this time, we are unsure when Newegg would have a fresh stock for the F3-12800CL10Q2-64GBZL memory kit.
If you are pressed for time, then 1866Mhz 32GB memory kit would probably be the best for you right now. Otherwise, there will be a temporary delay for an unknown period of time for the 64GB 1600MHz memory kit.
We apologize for the inconvenience. Thank you for your understanding and support.
Best Regards

Dear G.Skill Tech Support Team,
Thanks so much again for the complete and helpful information!
You guys are Fantastic!
All the best to you,

I also contacted Asus chat and asked the same questions.  They referred to their ram compatibility list that was released about the time they first started marketing their motherboard and that does not seem to have been updated to include current 32GB or 64GB kits.  They also recommended that I check the ram manufacturer's compatibility lists.  So they did not provide any info that I didn't already have.
An article on the Corsair website about memory compatability and whether one should fill just four of the motherboard's slots or fill all eight of them was also quite well written and very helpful:

One added benefit to the G.Skill Z series ram kits is that their heatsinks are short enough to fit underneath the very effective and quiet Noctua NH-D14 SE2011 cpu cooler.
Hope the above info helps.
All the best to you,

Wylin,
Have a look at Planning & Building a New System where I use the 64 GB 2133 kit and take a look at the Benchmark Results pages as well.
