4 out of 5 eggsOn the High-end Memory-spectrum - this is 80-85th%ile (GOOD)

Pros: 1) QuadChannel support;
2) 64GB set of memory;
3) Good XMP support;
4) Strong performance;
5) Used in multiple builds, reseated 50-60 times during build-up/tear-downs/troubleshooting/etc and no issues so far (did I just jinx myself???); and,
6) Price is reasonable for a 64GB set (yes, I see people squawking about price but come really, see what you are getting for this amount of $).

Cons: 1) difficulty of using supplied cooling/fans;
2) difficult time identifying 'support-status' in various motherboards QVL documentation

Other Thoughts: I like this memory, I do.
My only complaints are the fan/cooling 'solution' and the status of 'this' memory kit on various QVL mobo vendor documentation.
If the fans were put in as a 'bonus add-on' then I would not have subtracted an egg but they were a heavily marketed feature and (as you can read in the reviews) many people have issues fitting them in real-world builds.
Also, I would suggest that G.Skill work with motherboard vendors to update QVL documentation. For instance, I own the RIVE mobo and I can find 'G.SKILL F3-19200CL9D-4GBPIS(XMP) 4G ( 2x 2G )' but nothing for the 64GB kit while it is obviously supported given the existence of 'How to Enable X.M.P on Rampage IV Extreme' instructions floating around.
I mean, this only hurts G.Skill sales - how hard is it to get ASUS to update their docs that they will support the QuadChannel 64GB set of G.SKill sticks we are all reviewing?
All complaining aside, YES I would buy this memory again and I think G.SKill did a very good job of it.
Regarding the fan/cooling solution - if it is obvious that the fans won't work for the majority of users then either don't include them or throw them in as a bonus and don't represent them as a major selling point in the marketing materials. Look how many people had issues with them and gave less than ideal reviews for really awesome memory only because of brackets of the fans not fitting in various users build.

One more thing:

@Devon C. - can you please share your timings/config that you are using to run 2666Mhz???
Would really appreciate that... thanks.

Manufacturer Response:

Dear Customer

Thank you for your G.Skill purchase and review. Glad to hear you like this memory kit and it is working well in your system. 64GB of DDR3-2400 is definitely the most extreme RAM on the market for the X79 platform. It is for power users that are looking for the extreme processing power. In fact, only select few X79 motherboards can support such performance. For compatibility information, always visit the G.Skill website or send a quick email to the support department. Here you can find the QML for this RAM:

With this memory kit, you will have a super computer better than most high end servers. For any further questions or concerns, please feel free to contact us directly.

Thank you

Quality and customer service are our top priorities.

5 out of 5 eggsAmazing. Simply amazing.

Pros: - Easily handles 2666 Mhz without getting too hot when utilizing the provided fans.
- Really low latency, surpassed all other models i've tested in a benchmark

Cons: - None to date.

Other Thoughts: Although I think it could have been a bit more low profile, overall this is an outstanding product. The packaging was top notch and the memory handles overclocking really well.

5 out of 5 eggsExcellent Memory Set

Pros: 64 Gig, G.Skill

Cons: Unable to use the fan kits, Price

Other Thoughts: I love this memory set. It works great on the EVGA x79 dark. With the X79 Dark, you will not be ale to use the supplied fans if you have a large heat sink installed. I'm not too worried about heat from the memory, since my Noctura heat sink has multiple fans that move air over the memory. I can't fault Newegg or G.Skill for that though, so I didn't knock an egg off. This kit is expensive. Do your research first and save yourself a few bucks by going with the fanless kit.

5 out of 5 eggsUpdate: G.SKILL F3-19200CL10Q2-64GBZHD

Pros: This is an update to my previous review. I decided to give the system one more try.
First what I did is to re-flash the mobo's BIOS. I have Asus P9X79 Pro flashed with BIOS 4607.

Second (and I feel this is important) I've reset the BIOS, then took the motherboard's battery off and left it for 5 minutes, then installed it back.

Third, I've re-seated all 8 memory modules randomly on different slots.

Computer booted up showing all 65535 MB DDR3 1333 memory. I went and changed the memory profile to XMP1. F10, rebooted the computer and hooray!!! all 65535 MB DDR3 2400 memory are listed!

I've been running Memtest 4.20+ for almost 10 hours so far with 0 errors, so it is safe to assume that there is no problem with memory not being recognized in full capacity on 2400MHz anymore. Still not sure what helped, but I feel it was a combination of factors. Another good thing I noticed is that even after 10 hours of Memtest, 2400MHz @ 1.65V, the memory is running cool without active cooling that came with it.

Cons: NewEgg is not allowing to edit previous reviews as the big "A" bookstore web site does so I cannot edit my previous two-egg review.

Other Thoughts: Although the memory works just fine now, I had a rough time on the beginning and based on information I saw online there are other users with same problem as well. Do your homework, make sure your motherboard is compatible with this memory (and vice-versa), and try the approach above. It may work!

2 out of 5 eggsG.SKILL F3-19200CL10Q2-64GBZHD

Pros: 8x 8GB DDR3 2400MHz
Recognized by Asus P9X79 Pro
Runs cool even without supplied fans (but you should have sufficient airflow in the case).
Compact radiators that doesn't interfere with Hyper 212+

Cons: No matter I did I cannot get all 64GB work on 2400MHz using any of both XMP profiles - only 49152MB showed up. Updated motherboard BIOS to the latest version, re-seated memory several times, tested it in series to ensure modules are good - no luck. Very expensive - almost 700 even after coupon code.

Other Thoughts: Other users around are complaining about the same issue with this memory, just google and see yourself. I regret not doing my homework prior to purchase.

Manufacturer Response:

Dear Customer

We can surely help you with this problem. Many users are complaining about the same issue because they are using incompatible hardware. Simply because a motherboard supports 64GB and DDR3-2400, does NOT automatically imply it can support 64GB @ DDR3-2400. In addition, not all CPUs can support this RAM either. Only Intel K and X series CPUs are capable. As you know, this is no ordinary RAM, this is an extreme high capacity memory that pushes the maximum limits. If you refer to the Qualified Motherboards List, only the ASUS Rampage IV (Black and Extreme), X79 Deluxe, and MSI X79A-GD45 Plus motherboards are fully guaranteed for this memory kit. With one of these motherboards and a capable CPU, enable XMP and everything will run at full speed. With all other motherboards such as the P9X79 Pro, you can enable XMP, set the DRAM Frequency to DDR3-2133, and see how that works. If stable, then tweak voltages and such to see if you can stabilize DDR3-2400. This RAM at DDR3-2133 is still better than any other RAM on the market, so you will definitely get the maximum performance out of your system either way. Should you have any further questions or concerns, please feel free to contact us directly.

Thank you

5 out of 5 eggsAwesome!

Pros: Placed this kit in my Asus Rampage 4 Black Edition, i7 4930k.
Fast, Blazing..It does read the full 64gb at 2133 mhz. 1.65v.

Cons: I was able to use the full 2400 mhz. But my board only recgonized 50gb of the 64gb.. When I brought it down to 2133mhz it read the full 64gb..

Other Thoughts: Overall im happy. After reading nightmare posts on RMA of 64 gb kits..As far as reading the full 64gb at 2400 mhz... I am not the only one with this issue.

5 out of 5 eggsGreat RAM !

Pros: Using all 8 sticks in Windows 8.1 on Sabertooth x79

on fresh install windows would not install with all sticks in the mobo so only used 1 during install

Getting full spec speed on the set , Since i'll never use all 64gb i opted to use 16gb as a Ram Disk to load all my Adobe apps and 3ds Max. Read/Write on RamDisk is insanely fast !

Cons: None

5 out of 5 eggsWorks great on RIVE

Pros: Works great on my RIVE at 2400 MHz. Stable out of the box at this speed with minimal tweaking.

Cons: The included cooling fans (GSKILL) are impossible to mount on the RIVE. No room for the mounting clips on the sides.

5 out of 5 eggsWorks Great with the ASUS Rampage IV Extreme Motherboard

Pros: This G.SKILL memory has been working flawlessly on my Rampage IV Extreme motherboard since I installed it one month ago (June 2013). This memory was installed to increase the amount of memory on my existing system, which I built in November 2012.

The memory was easy to install. I followed the instructions that G.SKILL has posted on their website (google search: G.SKILL "How to Enable X.M.P on Rampage IV Extreme") . The glitches I ran into were typical hardware install issues that were easy to solve. Before installing the memory I upgraded the motherboard to the latest BIOS, version 4102. After removing the previous memory, I installed the new DIMMs in the 8 available slots on the Rampage motherboard. The memory height is short enough so that it fit under the Noctua NH-D14 SE2011 fan that overhangs most of the memory slots. On my first power-up, 48GB of memory was detected and the DIMM Post screen in the BIOS setup indicated that no memory was being detected in 2 of the memory slots. I powered down the computer, and reseated the 2 DIMMs in those slots and on the second power-up all 64GB of memory was detected. Next, I checked the auto-detected X.M.P. memory settings in the BIOS setup screens and saw that they were incorrect. I cleared the CMOS settings using the button provided by ASUS for that purpose and on the third boot the memory detected as DDR3-2400 at 10-12-12-31-2T.

I restored the CMOS settings to overclock my Intel Core i7-3960X to 4600Mhz and then booted into both operating systems on my dual-boot machine (Windows 7 Pro and Windows 8 Pro). All of my applications software were stable, but I could not get the system to validate under the IntelBurnTest software. I dialed back my memory setting in the BIOS to DDR3-2133 and this time some long runs of IntelBurnTest indicted that the system was completely stable. That is memory setting I kept and I am satisfied with a dramatic improvement is system performance.

Cons: The installation instructions provided by the manufacturer G.SKILL with the product are minimal, although G.SKILL does have an active and well-supported forum for customer support.

Other Thoughts: The purpose of this memory upgrade was to increase the performance of Matlab. I added this memory and a NVIDIA Tesla K20, following the recommendations on the Nvidia website for a 2nd generation Nvidia Maximus workstation configuration.

System Configuration:
ASUS Rampage IV Extreme, BIOS 4102
G.SKILL Ripjaws Z Series 64GB (8 x 8GB)
Intel Core i7-3960X, overclocked at 4600 Mhz
Noctua NH-D14 SE2011, air cooling

5 out of 5 eggsExtremely impressed with this memory

Pros: I'm a support engineer and need to boot clusters of virtual machines to simulate customer environments. I'm usually running 10 or more VMs at a time plus databases. I needed a ton of memory and a big processor with lots of cores - Core i7 3930K Sandy Bridge. I decided to max out a Sabertooth X79 and go with the Qualified Vendor List recommended kit ASUS recommended. This was the only memory that went to 64GB on that list. I've overclocked to 4.2 GHz stable, and 2358Mz on the FSB. I'm getting 7.32 MPTS and 73.5 GB/s on SiSoftware benchmarks! To quote Dave Chappelle as Samuel Jackson, MMM MMM ____!

Those Blue LED fans on top of the memory sure do look purty.

Also running Corsair H110 liquid cooler in a Corsair Obsidian 650 case

Cons: The price of course. $699 is hard to swallow. But I now have 64GB of DDR3 2400 goodness. I remember paying $400 for 16MB of memory in the early 90s as a poor college student. Upill in the snow both ways and we liked it!

The fan clips seem cheap and bendable and bump into the VCore heatsinks for the Sabertooth X79. I almost worry about them sliding off and falling down in my case, but I bent them in slightly so they are tighter. Some sort of adjustable screw mount on the top of the DIMMs would be more ideal.

Other Thoughts: BBQPWNT! Crysis 3 runs like a dream!
