Question Help with memory selection for New 3900x build

[rschilling]

I am putting together a new build:
Ryzen 3900x cpu
MSI x570 Unify ATX Motherboard
MSI 2060 Ventus OC
Noctua NH-C14s cooler
Corsair SF600 power supply
Corsair MP600 NVME PCI-E 4.0 1TB boot drive
Sabrent (or other) NVME 3.0 2TB storage
Cerberus X case

DAILY USE: CAD, 3d rendering (cpu and gpu depending on program), photo editing

Memory questions:
Want 32 GB (don’t need that much now, just want to get it and be done)
Do I favor speed over timings? Timings over speed?
Will use XMP – Set and forget, no manual OC.
2x16 or 4x8?

Best I can find right now:
3600
G.SKILL Trident Z Neo (For AMD Ryzen) 3600 32GB (2 x 16GB)
F4-3600C16D-32GTZN
$295. 44mm high. Timings: 16-16-16-36

G.SKILL Ripjaws V 16GB (2 x 8GB)
F4-3600C16D-16GVK
$130 40mm Timings: 16-16-16-36 Buy 2 kits? Will they match?

3200
G.SKILL Ripjaws V 32GB (2 x 16GB) 3200
F4-3200C16D-32GVKA
$180 40mm Timings: 16-16-16-36

G.SKILL Ripjaws V 32GB (2 x 16GB) 3200
F4-3200C14D-32GVK
$230 40mm 14-14-14-34 or 4x8 $249

G.SKILL Flare X 32GB (2 x 16GB) 3200
F4-3200C14D-32GFX
$230 Height? 14-14-14-34

G.SKILL TridentZ RGB 32GB (2 x 16GB) 3200
F4-3200C14D-32GTZR
$291 44mm Timings: 14-14-14-34

Any insight will be helpful. Thank you.

The X570 Unify uses daisy chain topology, which is optimized for 2 dimms, so don't get 4x8GB.

The 2x16GB 3200 14-14-14-34 Ripjaws V seems pretty good, if you don't mind the looks.
The Trident Z Neo will without doubt do better, but the price is much higher.
If you ever do change your mind about setting XMP and forgetting, the 3200 14-14-14-34 may be able to hit 3600 C16 if you manual OC.

Thanks for your input and time. I may just get the Neo and be done with it.
