I stopped buying ThinkPads when they messed with screen sizes (a long while they did not have anything 16:10 at 1920×1200 or better) and keyboards (no 6-row keyboard for me).
So below is the (at least partial) list of ThinkPads I own(ed) and features they so I can find back information on them in case of need.
Note I had the X201 despite the smaller screen size, as it was an excellent travel companion.

Below are the maximum memory configurations for the Thinkpad models I own.
Note these re only 7-row keyboard configurations, the 6-row keyboards were always “meh”.
I used this command to get the CPU information:
wmic cpu get name
As mentioned in PC3-8500 or PC3-10600:
As PC3-10600 is getting increasingly difficult to acquire, PC3-12800 can be used instead. Using PC3-12800 may or may not increase the performance of your model, as some models may underclock it to their respective original DRAM speeds.

You might think it would fit two 8GB modules and be upgradable to 16GB, but the chipset prevents it. Some of the W510 models seem to accept 8GB modules though:
So T510 only supports 8 GB RAM, potentially due to CPU limitation.
The first generation iCore i5 and i7 duo core did not support more than 8 GB of RAM

I actually still have 16GB in my version, see: ThinkPad W701: Win7 Ultimate x64 suddenly only saw 8GB RAM of 16GB (via: [H]ard|Forum).
Searching back my blog history, I did note that 32GB should fit: ThinkPad W701 with 32GB of memory via: forum.thinkpads.com • Newer 8G memory sticks in a W700, W701, W500, W510 ?

Some seem to differ however, and got 16GB to work, but others don’t, as only the lower 8GB are accessible:
I might upgrade the W701, order 4*8GB modules, test some in the X201, then order more if it works.
Just in case I want to ever get a smaller Thinkpad with 7-row keyboard that allows 32-gigabytes of memory, the state as of 2019 is pretty accurate as no 7-row keyboards were manufacturerd after that (not even the horrendously expensive T25, which was a 2017 model [Wayback]/Archive.is] My ThinkPad T25 review : thinkpad):

Whereas Windows 7 was really fast, Windows 8.1 on my ThinkPad W701 is very slow in an erratic way.
Need to check out this:
Windows 8.1 proves to be extremely slow on their computers, with Microsoft yet to address the problem with a workaround or a patch.
According to some posts on Microsoft’s Community forums, this is mostly happening on Lenovo laptops and the fastest way to deal with performance issues is to uninstall the “Intel Dynamic Platform and Thermal Framework” from the device manager.
In addition, you need to access the BIOS menu and in the “Configuration” screen, make sure you disable the DPIF option to turn it off completely until Microsoft comes up with a fully-working fix.

Earlier this week, I posted abut ThinkPad W701: Win7 Ultimate x64 suddenly only saw 8GB RAM of 16GB (via: [H]ard|Forum).
One of the search results in my query indicated it would be possible to put 32GB in it.
That’s nice, as the official Lenovo ThinkPad W701 specs and Lenovo ThinkPad W701 2500 Overview & Specs – Laptops – CNET Reviews indicate it should max out with 16GB.
This Google search returns lots of results indicating people actually run it with 32GB RAM using 4x8GB memory modules:

This recently happened to me, but not sure when it started:
My ThinkPad W701 had 16GB of RAM, and everything worked fine for about 2 years, but now the BIOS and Windows only saw 8GB of it.
The odd thing: SpeedFan would see 4 memory modules of 4 gigabyte each for a total of 16 gigabyte.
This solution helped:
the easiest (and most embarrassing) fix worked – just took out the new RAM sticks and re-seated them into different sockets instantly fixed the problem.
