DIMM modules have 288 pins
I count...
- 64 Address pins
- 64 Data pins
That adds up to 128
288 - 128 = 160
What are those extra 160 pins used for ?
I can imagine, +Volts, Ground, and perhaps clock signals, and perhaps a few other tricks of the trade that I've never heard of before.
But, 160 of them ? Duh.
Searching on the internet, I found this gang called JEDEC, as well as a zillion other firms.
I have so far been unable to find a clear, concise, and simple description of what the pins are for.
Interesting Observation: I was unable to find the expansion of the acronym "JEDEC" on their own website. They don't even say what their name is. Duh. Perhaps when I get $6,500.00 they will tell me.

The complete list is here: DDR4 SDRAM R[^] - pinouts start on page 5.
You'll notice that there are a lot of VSS and VDD pins: these can be thought of as power and ground respectively, and there are probably a lot of 'em because the traces leading to them are so thin and the voltages so low - but that's just a guess.

I would speculate, the remaing pins are 'ground' to seperate noise.
But only speculation 
[Edit]
Or more likely differentially signal lines
[Edit01] ChatGPT, take care..
Yes, this is indeed related to differential signals. In DDR4 memory modules, many signals are transmitted as differential signals. This means that the information is not transmitted as single voltages (as with unidirectional signals), but rather as the difference between two voltages.
Differential signal transmission offers several advantages, including better noise rejection and higher immunity to electromagnetic interference (EMI). This type of signal transmission is particularly important at high data transfer rates, as is the case with DDR4 memory modules.
Therefore, many of the additional pins on a DDR4 DIMM module are reserved for differential signal pairs to ensure reliable and fast data transmission. The ground lines we mentioned earlier also play an important role in providing a stable reference for these differential signals.

JEDEC is something like "Joint Electron Devices Engineering Council", a very old industry standards body.

no driver updates for Artesia M200 ... using VLC equalizer working. but sound murky.
better player than VLC ? possible interaction with Logitech g431 software ?

I'm not sure what you're asking for exactly.
But, I did have problems with "murky sound" a good while ago, when I had my old SoundBlaster X-Fi (USB) hooked up in such a way that it went through a USB2 connection rather than USB3.
Changing connections so I knew (for sure) it was going through USB3 fixed the problem. Which makes very little sense, since the device itself predates USB3. I rather strongly suspect this is because it went through a long chain of hub going through hub going through hub, and USB2 perhaps couldn't carry the amount of data from all devices that were all competing for bandwidth.
In other words: Try hooking up your G431 headset so it goes through a shorter USB3 path...?

Maybe a year ago I tried to compile my graphics library for MSVC and got a zillion errors in my template declarations. Or at least that's what I remember.
I couldn't figure out why, and even ranted here about MSVC not following the standards, but was corrected on that - apparently they do but the way they interpret them is/was maddening.
I figured it wasn't a huge deal since the library is IoT/embedded and that toolchain is GCC or Clang 95% of the time, or at the very least satisfying the 80% rule in terms of usage scenarios.
Today because it was 3am and I was for want of something better to do, I decided to try my hand at making my large library MSVC compliant.
Fired up a project, CMake, made a fetch_deps bat to pull in my dependencies and I got a few errors, and a handful of warnings.
The errors I fixed in several minutes and had nothing to do with my templates unlike before. This is a far cry from what I ran into last time.
Now it works, and I don't want to ask too many questions. I think maybe they fixed some things in the latest compiler, or if not fixed, at least more sanely interpreted the C++ spec.

It was a clever clue, and the first time I looked at it I was totally blank.
