I have a Terramaster F6-424 and the vendor site says that the machine can support up to 32gb of RAM. I am running TrueNAS on it.

I have tried 4 different 32gb DDR5 sticks and the machine refuses to POST (or whatever the beep is when it turns on). The latest one I tried I chose specifically because it said it supported my exact machine, despite the price. I don't know if I'm just missing some specific spec on the memory that makes all 4 of the sticks I've tried incompatible with the F6-424, but at this point I'm doubting Terramaster's claim of supporting up to 32gb.

I wanted to post here and ask if anyone has succeeded in upgrading/replacing the RAM in a Terramaster NAS before I return this last one and try a 16gb stick.

Is there something I'm missing here? Does running TrueNAS instead of TOS matter? Has anyone had success with any specific RAM model with this setup?

What is the exact memory spec that is supported? It should be in the manual. The spec of the working and not working sticks would be helpful too.

If it beeps, does it beep a pattern, and is that also covered in the manual?

That's part of my frustration actually - I can't find a useful manual for this thing. Just marketing materials, basic setup guides, and specs of what comes with it. The Terramaster site says that it is only compatible with RAM that they sell, but I assume that is just because they want you to buy their stuff.

No beep on any of the 32gb sticks I've tried. When booting with the 8GB stick it comes with, I get one beep.
