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

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, that's the exact RAM that I've been trying to remember the name of.

I don't know if you guys have noticed this or not but the entirety of the Prime K sequence ends up repeating itself after about 8 hours with most CPU's.

Yes indeed. Its just a power virus 😛

Some kits benefit greatly from tuning ProcODT.

For anyone, like me, who didn't know what ProcODT (Processor On-Die Termination) is, here is a link that should explain it: https://www.bit-tech.net/hardware/memory/2008/02/08/the_secrets_of_pc_memory_part_3/8

Great link! Thanks! :cool:

I updated to latest bios 1401 and had great sucess!!
I manage to boot all 32 GB at 3200 Mhz at cas latency 14 from the get go just by using DOCP.
System seemed pretty stable and passed most stress test but not the Google stressapp test that found right from the start and error.
I tried playing with ProcODT a bit trying everyting from 50 to 80 Ohms but either did not boot or made system more unstable.
Just changing command rate from 1T to 2T allawed me to pass 8888 seconds of Google stressapp test.
Good job AMD and asus!

so far the best ive managed is 3466mhz divider @16 16 16 36 57(reads 81 in cpuz) 1T
1800x @ 4.025 with 1.395v set in bios. gives me around 1.375v in windows. using p-states to oc. I'm having a lot of success with these Samsung b-die ic's. i take my hat off to those of you figuring out the other ic's.
