Do 3200 Mhz 64GB DDR4 kits currently exist that work with AMD RYZEN 1800X & Asrock Fatal1ty X370 Pro Gaming at Rated Speed?

[NewRigTime]

The title says what I am looking for, but I want to be more specific with how I got here as well. First of all, do NOT reply to this thread with any Intel-related info as I am dead-set on RYZEN now. I have done hours of research on this subject, and have come to the conclusion that the best memory I can get right now is the following:

Memory: G.Skill TridentZ 64 GB 3200 Mhz CAS 14 (F4-3200C14Q-64GTZ)
Purchase Link: https://www.amazon.com/G-SKILL-TridentZ-3200MHz-PC4-25600-F4-3200C14Q-64GTZ/dp/B01AQIQFUE/ref=sr_1_1?ie=UTF8&qid=1492984448&sr=8-1&keywords=g.skill+tridentZ+64gb+3200Mhz+dual+channel

I already know that I will need about 64 GB of memory for what i am doing - I use over 36 GB on DDR2 modules right now and looking to expand that capacity for 24/7 operation (this PC will NEVER be off for more than an hour or 2 at a time).

I want the 3200 Mhz capability so I can both run a massive number of programs in virtual machines that are memory hogs, as well as possibly play some gaming for a few hours per day on this same PC as well. The gaming aspect will require higher memory speeds to get this performance.

Am I taking a gamble of ever hitting the rated 3200 Mhz speed with this memory? Does anyone know if F4-3200C14Q-64GTZ is Samsung B-DIE, which seems to be very important with RYZEN? I know that AMD is planning a May update with motherboard manufacturers to address some DDR4 issues, but I don't know if this memory is ever going to exceed 2133 Mhz ever... I am fully aware that there are NO 64 GB MEM KITS available on the Asrock QVL list shown here:

http://www.asrock.com/mb/AMD/Fatal1ty%20X370%20Professional%20Gaming/index.asp?cat=Memory#Memory

My alternative is G.Skill Flare X 64 GB modules at the 3200 Mhz rated speed that I cannot seem to find for sale anywhere online. I know they exist (or will exist), because the offering appears on the G.Skill website here:

https://www.gskill.com/en/press/view/g-skill-announces-flare-x-series-and-fortis-series-ddr4-memory-for-amd-ryzen

Honestly I like Corsair better as a company over G.Skill, but it seems like G.Skill is the only option when it comes to RYZEN with 64 GB of DDR4 right now for optimal performance. Am I wrong?

Final Note: My CPU cooler will be a Noctua NH-D15 in a Silverstone FT-02 case. It will be an interesting build for 24/7 performance with lots of airflow. I may need to re-position the second fan to the other side of the cooler depending on the RAM height, because the case only has so much clearance and the second fan would not be able to stick out much. I will have to use just 1 fan on the cooler as a worst-case scenario.

Bump...Looking to order RAM soon so just looking for any info to run with. I may go with a not-on-QVL-List 64 GB set of G.Skill TridentZ rated at 3200 MHz if i don't hear anything..

Update 03-14-2017: AMD said that they have internally observed good results from 2933, 3200, and 3500 MT/s rates with 16GB kits based on Samsung “B-die” memory chips. Potential kits include:
Geil EVO X – GEX416GB3200C16DC [16-16-16-36 @ 1.35v]
G.Skill Trident Z RGB Series- F4-3200C16D-16GTZR [16-18-18-36 @ 1.35v] ($189.99 shipped)
Corsair CMK16GX4M2B3200C16 VERSION 5.39 [16-18-18-36 @ 1.35v] ($129.99 shipped)
G.SKILL Flare X Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 is considered the best atm.
Timing 14-14-14-34
Cas Latency 14
Voltage 1.35V

Quite often it's hard to get the high speed ram (like 3200) to actually work in its rated range without having some OC on the cpu, a small bump in vram voltage etc. Has more to do with the MC controller not being strong enough to handle the excessive speeds, than any failure on the part of the ram. Any ram listed on the mobo acceptance with (oc) next to it is a good indicator that further steps might need to be taken to get it to work at rated speed.

Well an AMD update is supposed to come out this month, not sure exactly when that will happen or if it will address anything for 64 gb ram users

Yes, but 16 GB kits do not help me hit 64 GB which i Need. I was already aware of this information.

I'm in the same boat as you and replying mainly because I'm hoping someone posts a solution. As best as I can figure if you can find DDR4-3200MHZ G.Skill RAM with a latency of CL14-14-14-34 it is probably your best bet, and may be Samsung B-Die

That's the best I've come up with which leaves me with the top two choices here
http://www.gskill.com/en/finder?cat=31&series=0&prop_6=Dual+Channel+Kit&prop_4=0&prop_14=DDR4&prop_2=64GB+%2816GBx4%29&prop_3=3200MHz

Otherwise, I could play it safe and get the G.Skill Flare X 64GB (4 x 16GB) DDR4-2400 but I don't want to settle for that slow of RAM

I'm tempted to go with the Trident or Ripjaws and hope that eventually the Microcode or BIOs updates will eventually make it compatible.
Sorry I can't be more helpful, good luck

I actually did buy the 2400 MHz Flare X 16 gb sticks, with the intention of selling them later on. I kind of want to look at Vega when it releases, but right now I built with just a Radeon HD 4850 (old as fuk!) video card i had on-hand. Computer is running, but i do not know for sure yet if it is stable. The compatibility issues with the other 3200 mhz 16 gb sticks could go beyond not being able to raise the speed up to 3200 mhz, so i decided not to take a chance with it.

 

[IanLlanas]

If you do any stress tests I'd be interested to know whether that RAM is stable or not. Right now I think I'm going to wait till the next update this May and see if G.SKill updates their compatible RAM to something I want. I hate waiting though.

Everything I've seen so far has been limited to 2600MHz.

"We noticed that no motherboards offer a memory strap beyond 3200MHz and asked AMD if this was a limitation of the processor architecture and we were told that it is just a limit in the base UEFI code and that it is not a limitation of the memory controller design or the overall Zen architecture. So, right now the memory strap limitation is on AMD’s side and that the DDR4-3200 is the highest memory strap you can get today. AMD is discussing changing that, but right now it is just a talking point. Official Ryzen DDR4 memory support is listed above. The dual channel/dual tank/4 DIMM support of just 1866 MHz just goes to show how far AMD needs to come. Singe Rank Memory is memory with chips on only one side of the stick of memory, although we have seen some exceptions of the years."

"Best performance with Samsung B-die is achieved at 145 MHz REFCLK with 2400 DRAM ratio (3480 MHz) at 11-10-10-10-22 timings. Alternatively 135 MHz REFCLK with 2666 DRAM ratio and 11-11-11-11-22 timings. This depends on the CPU/MB/DRAM capability."

I bought two 2800MHz Trident Kits (F4-2800C14D-32GTZ) for 4x16GB on your same mobo and it refuses to run over 2400. I wasn't shocked by this given the specs every actually show that once you populate all 4 RAM slots you max at 2400, though I had hoped the board would still honor the overclock.

From what I've heard, with 2 sticks only you've got good odds of at least hitting 2666 consistently and higher in many cases. I read one time of a guy apparently getting super lucky at 2900 with 64GB.

I'm hanging on to the hope that future BIOS updates will crack the RAM clocking mystery, as is typically the case with this type of thing. For now its a total crapshoot. Even if you order identical RAM to someone who has successfully clocked it to 3200, you might get sticks with a different die and not succeed.

*BUMP*

I have more or less exactly the same requirement.

That is I need a stable machine w. 64GB RAM running at 3200 Mhz, thinking of the same CPU and mobo (well, Taichi maybe) as above.

I could care less about OC solutions, because they will inevitably compromise stability and disrupt long jobs.

My build is sadly on hold until I get some answers more information towards OP's goal gratefully received.
