New AMD build can't decide on RAM...

I'm in the process of building a new AMD system but cannot decide on which RAM to purchase!

Its going to be paired with a X570 ROG Dark Hero MB and a (for now) Ryzen 5600x CPU.

I've picked out the below so far:

1) G.SKILL TridentZ RGB Series 32GB (2 x 16GB) DDR4 3200Mhz DIMM (F4-3200C16D-32GTZR)
2) Corsair Vengeance RGB PRO White 32GB 3200MHz DDR4 Memory Kit (CMW32GX4M2E3200C16W)

Both are rated at the same speed and CAS (CL16) but with a slight difference in timings with the G.Skill being slightly more expensive.

Any issues with the above in regards to compatibility as neither are on my MB's QVL list?

I've read that AMD is much more picky with RAM than Intel systems so want to make the right choice.
I'm not bothered at the moment about overclocking as the PC will mainly be for work but some gaming too so I'm more interested in a stable system first and foremost.

So is either the above sets OK or am I best to look at something else?

Thanks in advance!
 
Ryzen is a bit less finicky than it used to be, but for best compatibility, aim for 'b-die' RAM.
Generally, at 3200MHz this will be cl14, and cl16 at 3600MHz.
3200/c16 kits have been known to cause some issues. The b-die kits tend to just work more reliably.

Edit: not much to choose from at present, and prices seem ridiculous... Of the two kits you list, either SHOULD work OK. Given the lack of reasonably priced options, I should wait for someone else to chime in...

Thanks a lot DoneADougalOnSofa.

I've looked for 3600Mhz memory at CL16 but couldn't find any, all 3600Mhz kits I found seem to be rated at CL18 at the moment. I was under the impression that the CAS rating was more important than the speed which is why I picked the above 3200Mhz kits but I'm no expert as you can probably tell!

Is 3600Mhz at CL18 ok to go for, again compatibility and stability is my main concern?
 
To be fair, I think the situation is better now than it used to be. When the first two Ryzen generations launched, it was a bit of a nightmare for many- myself included. The c16 stuff just didn't work. C14 did, that was how it was.
BIOS and AGESA updates have made things much, much better, so my experiences are a couple of years out of date now!
Plenty of folks using same mobo/chip you've got, I'm sure someone will pop up with a recommendation soon.
 
The b-die seems to have shot up in price.
I paid 99.99 for my second kit (from 16 to 32GB), 180 for the first.
Seems it's back up to silly money again, which I guess indicates demand... The 'slower' kits are half the price!
 
Generally, the timings. For 3200, if it's CL14 (and more expensive) then it's almost certainly b-die. That usually scales to CL16 for 3600MHz kits.
Other makes include Hynix and Micron, and these tend to be 16 for 3200 and 18 at 3600.
I think Micron stuff behaves itself, many of the issues were with the Hynix based kits. But as I say, things are a bit better now...
 
Well I'm going to go for this kit: Corsair CMW32GX4M4C3600C18W

Its 4*8gb (ideally wanted 2*16gb dimms) Samsung memory but it's on the MB QVL list which is the main thing although its more expensive :(.
Just have to wait for it to come in to stock now!
