Ok the ICs (actual memory chips) are a bit worst than mine but it doesn't matter all that much. Major factor about RAM OC for Ryzen is the UMC (Unified Memory Controller) of the CPU and I bet yours is better than mine cause R9 3900X is a higher quality chip overall than R5 3600.
As i thought the modules are 1 ranked (says so the "Memory Module" -> "Organization" on Thaiphoon) meaning that all 8GB is on 1 side of the modules like most 8GB sticks.
First you need to get a starting point for your DRAM performance and how is it now. You can run "AIDA64 cache and memory benchmark".
First raw is the important about mem read/write/copy bandwidth (higher) and latency the most out of all (lower)

Your bandwidth could end up higher than mine and latency lower due to higher threads and speed of your CPU.
Be aware that AIDA64 is a paid benchmark. If you dont want to pay for it then you can run the individual 4 tests for memory read/write/copy/latency like this...

You can find the first pic memory/cache benchmark right above the Start button in Tools drop down menu.
Run them 1 or 2 times each and save the numbers.
When you get the current performance you can proceed with DRAMcalculator like this

You dont have to set all the settings provided here but just those in blue squares for start. All else in
auto and
XMP disabled. All these settings are in the
Tweaker page of your BIOS. Set the mem multi to 36 and timings in the
Advanced Memory Settings. Be aware that the timings order is different in BIOS.
The 1.35 recommendation for mem voltage is really for high end/quality B-dies and ours are not... Mine works with 1.4V (DRAM voltage CH A/B) for these kind of settings. Max recommended safe 24/7 mem voltage especially for b-dies is 1.45V and some users do even 1.5V with active cooling upon modules.
Under
AMD CBS and
XFR Enhancement (settings page) in BIOS you will find the IF speed (
FCLK set it to
1800MHz)
You also need to be sure about the matching speeds of DRAM and UMC so set the
UCLK DIV1 MODE to:
UCLK==MEMCLK
Also you can set the
SoC/Uncore OC Mode to
Enable. This disables the power savings of the SOC/IO die and can help with IF/UMC OC (can raise the avg power consumption of SOC/IO by a few watts, but nothing really important)
Feel free to ask further questions and/or clarifications. Once all set (double checked) and before save and exit I suggest to save this profile preferably to a usb stick.
When you manage to boot and get in windows first thing is to open RM and see that you have the correct settings.

Run AIDA64 again and see what you have gained. You can run other benchmarks before and after, like 3d marks, superposition, blender or anything you like. Higher mem speed and lower latency is not benefit CB scores all that much but you can run them too...
EDIT: some typos and...
The 3rd page of RyzenDRAMcalc contains a memory benchmark/stability test (last about 2~3 min) and it is a good show about the overall stability of the memory subsystem as a whole. If you finish it without errors there is a good chance that your system is stable by 99% if not 100%. Just click RUN as is, and dont do anything else. The test will start after 5~10sec.
And definately do some real (AAA) gaming too for at least ~2 hours sessions.
