I have tried every configuration possible: swapping sticks, single stick in 1st port, than in 2nd port, than the same with the other stick. All failed.
The instability you are encountering is still puzzling for me. Typically, my experience for these situations is bad/marginal Signal Integrity on the DDR modules, leading to instability. However, I find it hard to believe that Crucials would exhibit such behavior. It's still possible, as I have worked with physical DDR chips from the big 3x of Samsung, Micron, and Hynix. On another note, DDR4 requires higher refresh rates to errors, and, as these are non-ECC, I have to wonder if you are occasionally hitting some issues. In any case, I have to wonder if QNAP has marginal SI with the way they've laid out the PCB perhaps for the DDR.

I don't have any sticks at the moment. At first I was thinking to buy 2x8GB set, but than I read here that @larienz had luck with 2x16GB set, but 2400MHz version. What would be the best option in your opinion?
My tendency is to think that using anything >16GB is overkill for this processor. In reality, for my use-cases, even 8GB is mostly tenable. However, if you run enough VMs that just all need to be loaded but don't hog CPU, then it makes sense to consider more RAM.
For fun though, I bought 2x16GB Samsung's (2x M471A2K43CB1-CRC) to test out, as they were cheaper. Good thus far, but still testing. I am getting another set of Crucials later, after they get cheaper hopefully. In the meantime, I might try some Timetec or Teamgroup's later, as they're also cheaper. I'll get back to you on my findings.

@hopeandnotexpect, unfortunatelly using dmesg in investigation didn't end up with any new clue. I attached log & metrics (5 min before connection was lost). Maybe there's something I'm missing, so I would be great if you could look at it.
It's a long shot, but now I have put 1 module (16GB) from 32GB set + the one I originally got with qnap (4GB), so we'll see...
Sure, I would be more than happy to look at the dmesg to see if I can find anything. Did you send anything to me already? I don't see an attachment or PM.

I ordered this off Amazon. Been up with zero issues since Feb 14, 2022
Crucial 16GB Single DDR4 2666 MT/s (PC4-21300) DR X8 SODIMM 260-Pin Memory - CT16G4SFD8266
Except for file storage and Twonkey media server the TS-653D is not doing anything more at the moment.
Awesome to see the success. I personally would have bought the 2400Mhz and 2x8GB to get dual-channel, but what you have is more than reasonable. Be sure to test it for a week at least to ensure it is good. =)

Two weeks ago I bought my TS-453D-4G. One memory slot was free, so I stumbled upon Your post () here. I went ahead and bought the KVR26S19D8/16, since here in Croatia, at the moment Crucial is more expensive than Kingston. Anyway, I can confirm that it boots up and recognizes the module properly, it works. 4+16 RAM, more than enough for my needs
And the NAS seems snappier than before, but that's just the first impression maybe
Will have to see if it continues to work normally for a week or two, but for now it seems stable
Haha... Funny enough, Kingston has been more expensive as of late in the US (not usually the case). I am buying Crucials, Samsung, Timetec, or Teamgroup memory right now instead.
It'll be snappier for the first 8GB because of dual-channel. The leftover 12GB will still be advantageous just due to the shear amount of memory. Still very good though. And, yes, that's a great memory module to use/buy. Nice job! Looking forward to another update with long-term testing.
