Picking Ram

QVL list mean that the RAM sticks XMP profile will be reconized by the motherboard and set the XMP profile to the ''optimal'' rated frequency and timings as adverted by the sticks manufacturers, it doesn't mean it won't work nor can't do better then what your sticks are advertised to run. Grab anything rated at a decent speed with good timings, both kits you are refering to with knowing what chip they actually use are the same, but one of them can run at high frequency, but as worst timing. Basically if you bench those two sticks they will probably have the same latency, write and read speed.

 

If you don't want to mess with the timings and frequency get RAM on the QVL, but thats not 100% sure they will run at rated speed out of the box....

What i would do personally, is get the best i can afford and watch youtube tutorial to set frequency and timings manually. Then try to overclock the sticks as much as you can, but you have to buy some decent stuff at first other then that you won't have much overclocking headroom.

Cheap stuff usually have Hynix A chips on them and these don't like fast frequencies, tight timings and don't scale with voltage

A good cheap kit is the Crucial Ballistix Sport LT 3000-3200mhz, you can push them to 3200mhz CL14 and those a usually bad kits..... good kits can run 3600 CL14-15

Which is most important? Memory timing or frequency?

 

Im gonne use a ryzen 3700x cpu. And at the moment i am considering these 2 sticks (2*16gb)

 

3200MHZ & CL16

3600MHZ & CL18

it's usually about the ratio of frequency to timing. in this case, they are the same thing. try to look for your motherboard's QVL and see if any of the modules are on the official supported list, that's usually more important.

If it ain't overclocked it ain't good...

If your going to use a 3700x get 3600Mhz expecally if you dont feel like doing any OC on the RAM. This will allow a 1:1 optimal ratio for the infinity fabric. If you feel conformable OC the 3200 to 3600 you will probably end up with close to the same timings as the 3600Mhz kit.

MCLK and FCLK can be adjusted to anything, you can run anything from 1333 to 4800mhz if your IMC can handle it.
