Librem 13v1 is Broadwell, not Skylake 
Ohh. Thanks for correcting me.
A friend just tested the Samsung with a Librem 15v3, and it also works. The CPU is i7-7500U (kabylake).

I just bought the Mushkin for my Librem13v2. I’ll report back when I receive it.
we’ve been testing 32GB modules on both the 13v4/15v4 and will be announcing it as an upgrade option shortly
edit: looks like we already have

The Samsung 32GB RAM is working well with my Librem 15v3.

I just put one of these in my v4 and it works great.
Unwisely, I had ordered the bare-bones memory configuration, which was 8GB of 2100 MHz Kingston RAM. Often on boot, there would be some sort of timing glitch and the hard drive wouldn’t always get decrypted. That seems to have gone away with the 2666MHz RAM.
Reviving this thread.
I just bought the same Samsung module (32gb, 2666MHz, M471A4G43MB1) for my Librem 13v2 and it won’t boot with the dimm installed.
Now before I’ll try and return it I’d be interested if anyone has an idea why that would be. Librem is updated to the latest coreboot image. I didn’t test the memory itself for lack of a second DDR4 laptop, but I’ll try to get my hands on one.
Not seated correctly?
Otherwise, I don’t know whether anyone above reported that 32GB module works with a v2 so maybe report the exact CPU model number here. There are reports above that the v3 and v4 work with 32GB RAM.
Installed it twice to make sure seating was good (there’s only one ways to insert it anyway). The 13v2 runs on an i5-6200U Skylake.
I guess it is frequency mismatch. But mainboard should be able to slow down RAM frequency itself, isn’t it?
DDR4-2133, LPDDR3-1866, DDR3L-1600
I don’t think so - otherwise all the Librem versions would have the same problem? Look up the later CPUs and they show the same types of RAM.
How long have you waited on boot?
I can now only speak for a non-Librem, non-core boot computer I have upgrade to 32GB ram. But my experience says that it has to check the ram on First boot after installation, which for 32GB can take a minut or so.
But I also endes up discard the First 16GB block I bougth. Which I still believe just didnt work.

surely you meant i7-6500U right?
I just wanted to chime in as well: I put the Samsung ram linked above in and it fired right up, after about a 20 second pause on first boot.
I have a Librem 13 v2.

I’ve tested that module here on a few 13v2’s here as well, no issues.
It’s important to remember that the Librems will take about 20s to boot whenever the RAM config changes, or whenever the firmware is updated, as the firmware has to perform RAM training to identify the proper RAM timings/config for the currently installed modules. This data is then cached and reused on subsequent boots until the config changes or the cached data is cleared.

My 13v2 has an i5-6200U - the same configuration that was tested e.g. in this review.
I gave up after about 10 minutes.
But I was now able to try out the module on a different machine with an i5-7260u, where it also won’t boot. Suspecting it’s faulty I’ll try to return it and try another one.
Was any one of those sporting an i5? Because so far everyone else here seems to have had success only with i7s.

the one I tested on was an i7-6500U, but I also have an i5-6200U I can test later today

Just tested on a 13v2 i5-6200U non-TPM model, no issues booting the 32GB Samsung DDR4 module
