4 x 16GB, 8 x 8GB, or 2 x 4 x 8GB sticks for 64GB for Ryzen 1920X/1950X build

4 x 16GB (one kit of 4 sticks).
8 x 8GB (one kit of 8 sticks ).
2 x 4 x 8GB (2 identical kits of 4 sticks).

Are 4, or 8 sticks, easier on the IMC of a 1920X or 1950X Threadripper ?
4 vs 8 sticks. 4 x dual rank, or 8 x single rank.
(I'm aware that IMCs in Threadrippers are quad channel.)

I currently actively using a i7-6850K X99 box for web dev and web design, and coding, and a 2950X X399 box as a local testlab (runs Linux KVM hypervisor with 9 VMs : Arch Linux, Win10, OS X 10 Hackintosh, Android-x86, and headless : 2 x Debian web server, MySQL DB server, DB2 DB server, MongoDB server, and some other very low traffic servers).

I want to replace the X99 box, with a X399 + Threadripper 1950X (because they are so damn cheap now, and because of the cheap Threadripper motherboards).
But the memory QVL list of the Asrock motherboard is not very helpful.
I only got two interesting kits of it : G.Skill Trident Z F4-3200C16Q-32GTZB, and Kingston HyperX Predator RGB HX432C16PB3AK4/32. Which both are 32GB kits, which means 2 x 4 x 8GB.
And of course there is the 4 x 16GB G.Skill Trident Z F4-3200C16Q-64GTZ kit, which is currently in use in my testlab.

So far I have the following for my new box :
AMD Ryzen Threadripper 1950X Boxed
ASRock X399 Phantom Gaming 6 / Gigabyte X399 AORUS PRO
NZXT Kraken X62
Akasa PWM fan splitter cable, 5 pwm fans on 1 mainboard (ak-cbfa03-45)
Plus the PSU, GPU, NVMe and SSD drives, etc from my X99 box.
