You don't really want to go lower, your choices are minimal and likely very expensive.So 14 or lower latency or exactly 14?
Samsung b-die are usually 14-14-14-34 CL14.

As someone with non-samsung memory, I'd highly recommend spending the extra $50, I wish I did.
And yet my Asus Prime X370-Pro can't go above 2933 and 16-18-18-18 on my Hynix G.Skill RAMAs someone (Asus B350 Prime-Plus) with GSkill Hynix 3000-Mhz ram, and rated at 15-16-16-16 timings. I am happy with my ram running 14-15-15-15 @ 3066mhz settings. To each their own obviously.
My Team Vulcan DDR4-3000 16-18-18-38 1.350V 2x8GB kit, won't run / POST reliably above 2667, in my ASRock AB350M Pro4 board, even with UEFI 3.00 with AGESA 1.0.0.6a. Sigh.

Just a heads up, Gigabyte boards are having issues with Sound Blaster PCI-E sounds cards not getting detected on certain reboots. Can't be fixed via the BIOS it seems and requires RMA - probably a good idea to wait for new revisions from Gigabyte. Additionally, the soft brick issue root cause still has not been found.

What is the "soft brick" issue and which board(s) and UEFI version(s) does it affect?
I have not experienced this with either the Gigabyte X370 Gaming K7 or AB350 Gaming 3, and I have used initial BIOS up to 1.0.0.6 on those boards (though consider 1.0.0.6 UEFI update first "stable" UEFI)
Here's a quick guide for Ryzen people wanting to try this on their computer but don't want to install Linux (but have Windows running)
BIOS Setup: (may not have to do this for people with stable rigs)
Load Defaults (save and reboot)
Load XMP Profile 1
Enable SVM (Virtualization)
Disable CSM
Save and reboot.
Couple of Pre-Requisites:
1) 16 GB USB Drive
2) Download RUFUS Tool for Windows
3) Download artful-desktop-amd64.iso *OR* ubuntu-17.04-desktop-amd64.iso
Note: daily builds of Artful Aardvark comes with Kernel 4.11, while Zesty Zapus comes with Kernel 4.10.
4) Burn ISO image using RUFUS Tool onto USB Drive
5) Download AOMEI Partition Assistant Standard (Free)
6) Run the Partition Assistant program and resize the FAT32 partition on the USB DRIVE to 4 Gigabytes, then apply the changes
7) Add a second partition with a file system type of "Unformatted" to the USB DRIVE, size it at 8 Gigabytes, then apply the changes.
Actual Procedure:
1) Plug in USB Drive
2) Boot to UEFI
3) In the UEFI screen, select Exit Tab -> Boot Override -> UEFI : USB Drive
4) In the GRUB screen, make sure "Try Ubuntu without installing" is highlighted, hit ''e" key.
5) Change the section with the words "quiet splash" to "nomodeset" then hit "F10" (note, only change those two words, only needs to be performed on GTX 1080, or 1080TI+).
6) It should take you to the ubuntu desktop
7) Turn off screen saver
Artful Ardvark (17.10):
System Settings -> Power -> Power Saving [Section] -> Blank screen = Never, then hit the [x] icon to close the window.
Zesty Zapus (17.04):
Navigate [Gear Icon] -> System Settings -> "Brightness & Lock" -> "Turn screen off when inactive for: " = Never, then hit [x] icon to close window
8) Right click on desktop and select "Open Terrminal"
9) In terminal, type "sudo su -"
10) It should log you in as root and change your working directory to /root
11) Type "free" - if it's showing you have 8 Gigs of SWAP then ignore SECTIONS 12 -> 15
12) Type "lsblk" to get a list of drives and partitions available in the system
13) Locate the block device alias for your USB DRIVE (in my system - it was /dev/sdb)
14) Type "mkswap /dev/sd?2" - replace the question mark with the correct device alias letter
15) Type "swapon /dev/sd?2" - replace the question mark with the correct device alias letter, this will use the secondary partition on the USB DRIVE as system swap space
15) type "wget http://funks.ddns.net:8080/tools/ryzen/testRyzenGCC.sh"
16) type "chmod 700 testRyzenGCC.sh"
17) type "./testRyzenGCC.sh" to startup the GCC 7.1.0 build loop which will download the pre-reqs
18) If the build loop crashes or stops, then you got something funky going on with your system
Note: may be a good idea to open up another terminal and run "top" to see what's going on while GCC is compiling. Bad practice to run things as as root but this is a live usb. My setup needed the "nomodeset" setting otherwise the GUI doesn't come up.
I see a video comparing single channel vs. dual channel, not single rank vs. dual rank.another note on dual ranked RAM is that they are faster than single ranked RAM. especially with ryzen: https://www.youtube.com/watch?v=u827fdCOCao (anywhere between 5%-15% performance when the GPU is not being bottlenecked)

oops. sorry, grabed the wrong link.

according to them, a 3200 MH SR is approx equal to a 2666/2800 MHz DR, depending on what game/application you are running
It also looks like guaranteed B-die RAM is even more overpriced than normal DDR4,
But isn't that $50 better spent going up a processor tier (or gpu tier) instead?Samsung b-die are the chips used on the DIMMs. They're highly compatible with Ryzen systems and basically guaranteed to have no problems hitting the desired rating for the memory. Considering how well Ryzen scales with memory speed, you want at least 3200 b-die CL14. As someone with non-samsung memory, I'd highly recommend spending the extra $50, I wish I did.
