Best chance to get 3200 Mhz ram or more with 4X8 GB kit

[SexyTerrorisT]

Hello to fellow rog enthusiasts.

For TL;DR (Too long ; Don't read) jump to last paragraph. Thanks in advance

Seeing how ram bandwidth really drives performance on some games and other latency sensitive application i was thinking what would be the optimal decision to make regarding ram purchase.

I have currently ordered a Gskill F4-3200C14Q-32GTZR ram which as its name suggest is a 4X8 GB RGB kit from gskill rated for 3200 Mhz for intel platform.
I know AMD does not support officially support that kind of speed for 4 dimm single ranked modules but a lot seem to have managed to reach those speed with various BIOS by overclocking.

Demand for kits at 3200 Mhz has been very high and its very hard to find them is stock. I am considering dropping the ram i currently have ordered and getting higher rated kits at 3600 Mhz or even 3866 Mhz (for intel platforms) which are in stock

Instead of waiting for the F4-3200C14Q-32GTZR
https://www.gskill.com/en/product/f4-3200c14q-32gtzr

to arrive I am specifically eyeing the following (yea i am in love with the looks for this line of RBG) since those even though more expensive are in stock:
- F4-3600C17Q-32GTZR
https://www.gskill.com/en/product/f4-3600c17q-32gtzr
- F4-3600C16Q-32GTZR
https://www.gskill.com/en/product/f4-3600c16q-32gtzr
- F4-3866C18Q-32GTZR
https://www.gskill.com/en/product/f4-3866c18q-32gtzr

From what i gathered all those kits must be Samsung B die chips inside. Best memory manufacturinng process or ram atm. Is that assumption correct? Any chance any of those have the undredly hynix ones?

I know getting above 3200 mhz is pretty much a wet dream now and probably in the near future with a Ryzen 7 1800X and a 370X chipset but my train of thought is that the next iteration of ryzen should also run on the crosshair VI hero and most likely will be made on a better and more mature manufacturing process. This process then should support better speeds.

Some reading of the crosshair VI hero overclocking thread of overclock.net i found some intresting data.
http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread

Both the ram i ordered F4-3200C14Q-32GTZR and the F4-3866C18Q-32GTZR have managed to get 3200 Mhz stable with 32 GB.
The F4-3866C18Q-32GTZR has managed to do so with slight higher voltage. Then again this might be due to varition of the IC in memory controller

DIMM Part number DRAM IC DRAM Configuration BCLK Frequency DRAM Ratio DRAM Frequency Timings Voltage CPU SOC Voltage BIOS version
F4-3200C14Q-32GTZR Samsung B 4x8GB 100 3200 3200 MHz 18-16-16-38-75-2T 1.35 1.1 Bios:0083
F4-3866C18Q-32GTZR Samsung B 4x8GB 100 3200 3200 MHz 18-16-16-38-2T 1.4 1.15 0902

My understanding is the 3866 Mhz kits since is better ic ram can run at 3200 14-14-14-36-2T but the F4-3200C14Q-32GTZR most likely wont be able to reach 3866 at the more loose timing of 18-19-19-39-2N unless you are really lucky. Ryzen 7 seems to care more about speed than timings.

Should i get the more expensive but faster in stock F4-3866C18Q-32GTZR kit or wait for the out of stock F4-3200C14Q-32GTZR but cheaper kit to increases chances of getting 3200Mhz with 32GB(regarless platform considered)? Maybe the F4-3600C17Q-32GTZR or F4-3600C16Q-32GTZR.

Thanks in advance.

Nice. Have you run GeekBench on it?
I'd be interested in seeing how close to identical a 1700 at 3.7 with 3200 memory is to a stock 1800x with the same memory.
Your timings are better than what I can manage currently. Might even score better than mine.

You running just 2 sticks of RAM?

Sure, I never ran this before but here you go, seems comparable to other similar set ups, how does it look to you?

Yes I'm running 2x8 of the Gskill Flare X. Will eventually get 2 more but just wanted to make sure this kit had any issues.

[BaneSilvermoon]

Ah, I've got 4 sticks. The extra RAM might make a difference in Geekbench scores.

I finished building and testing my system. I decided to wait for F4-3200C14Q-32GTZR. Even though I intended to build a watercooling system i bought a CPU air cooler to first test the hardware on. Artic Freezer 13 CO. It has clearance issues with ram so could only test 2x8 initially.

Bios 1107
2x8GB @ 3200 Mhz 14-14-14-34-1T BLCK 100 worked immediately.
4x8GB would not work @ 3200 Mhz 14-14-14-34-1T
I did manage to make it work @ 3200 Mhz 16-14-14-34-1T with 120 BLCK and 2666 strap however this gimped the performance of my M2 960pro at 2 GB/s instead of 3GB
i finally settled for the setting i had found beforehand @ 3200 Mhz 18-16-16-38-1T although @ 3200 Mhz 18-14-14-38-1T seems good too.



Did various stress testing and a lot of gaming at 4 Ghz with 1.44V on CPU with no issues.
The only stress test i could not pass was intelbrun test v2.54 in extreme mode. (right click the start button)
I can't even pass the exterme test with maximum ram even at stock( cpu@3.6 and ram @1866/2133)! Can anyone else give it a try and tell me if they can pass 10 iteration of extreme mode? I usually end up with a black screen.

The DDR4 3200 ram speed isn't a pipe dream on Ryzen, but you're looking at the wrong G-Skill ram.
You want G-Skill Flare X ram which is specifically made for AM4 & Ryzen.

I am aware of this ram. Not a fan of the design and I does not have fancy RGB lighting but costs as much 😉

Notice how there is no 4X8 GB Flare X kit rated @ 3200 Mhz
http://gskill.com/en/finder?cat=31&prop_2=32GB+%288GBx4%29&prop_3=0&prop_4=0&prop_1=0&series=2954

Gskill did not manufacture a new ram chip form AMD; they use the finest Samsung B die ram. Maybe a chip they would rate for higher speeds on Intel platforms.
The dual version of the RGB kit i ordered is listed on Asus QVL as runnig at 3200 Mhz.

Both 2x8 GB kits ( RGB and Flare X) have 14-14-14-36 timmings. What gskill does not say is command rate on Flare X

Seen anybody run 2 3200 Mhz 2X8 GB Flare X kits out of the box without an timmings or voltages adjustement whatsoever? If so your point might be valid but have not seen anybody so far. I really need the 32 GB as a big data dev. I would go 64 GB if speeds were not so low..

This chap has managed 3200 Mhz with 64 GB
http://valid.x86.fr/yb5uxm
And this one just shy of 3000 Mhz

Hello

It is doubtful you will see this with any real stability. Most of the claims being made for memory stability should be taken with a grain of salt. CPU-Z validations and Cinebench results do not indicate memory stability. Although AMD still has quite a bit of work to do on this platform a lot of the posted issues can be traced to memory instability from incorrect user setups.

Hello

I agree think most times it does indeed need to be taken with a grain of salt. Maybe the next AMD update will let it push the envelope a bit. Stability is quite relative for many overclockers but there are some industry standards for that depending on the need.
