Sure, just remember that there is no guarantee what works for one set of components will work for another - even if all things are identical. AKA the silicon lottery.
The ram kit I am using is the Bdie variant of the NEO 3600 CL 16, not the Hynix CJR. So that's something to check. The 3900X I'm using seems to handle the 1900 IF OK. (Tested with 4 different kits of Ram and on two different motherboards.) It's not guaranteed the Infinity Fabric can be clocked to 1900 - That's another possibility for not being able to achieve the same settings.
This is working for my system (Image attached was saved when I setup my system.):
I am using the values from the recommended column where ever there is an option to choose. With a couple exceptions - my DRAM Voltage is 1.4 not 1.42, and tRRDS is 4 not 3. And, one more thing on cLDO VDDG - I used that same value for both cLDO VDDG IOD and cLDO VDDG CCD.
Inside the Master UEFI - be sure to be careful when entering these values in - the ordering of the settings is not the same (you can't just take the settings from the calculator and start entering them into the bios/UEFI going straight down the list one for one). Also, where ever there is a setting in the UEFI that the DRAM calculator did not cover I left it at Auto.
I don't recommend just blanket using my timings - I suggest you calculate a custom set based off your ram kit.
Get/install Thaiphoon burner - read your dimms, click report scroll to bottom and click Show settings in nanoseconds. Now export that report as complete HTML - save it somewhere.
Get/Install Ryzen DRAM calculator (latest version is 1.7.0 as I post) set it up for your memory and ranks CPU/Chipset etc. Then click import XMP point it to the HTML report of your ram you created with Thaiphoon burner. now click Calculate Fast or SAFE - Try the settings out.
