Hi Self Hosting Lemmings!

I'm looking to upgrade the RAM in my 3-node proxmox cluster and could use some advice. I have 3 HP ProDesk 600 G3 Mini PCs that claim to support up to 32GB of RAM. However, I would really like to upgrade to 2x32GB for 64GB total.

Is it possible to run with more RAM than the recommended amount? If so, are there any problems I might run into? Any insight is greatly appreciated, thanks!

I would get one 2x32 kit somewhere you can return it (or even 1x32 if you are worried) and try it out, sometimes it does work but sometimes it won’t POST. Like the other person said, it might work but there really isn’t a way to know for sure other than that. I have run into situations with systems like that where that was just the largest available at release date for them to test and validate and larger DIMMs work fine so it’s probably worth testing in my opinion.

I am curious myself, let me know if you do test it, those look like cool machines for small clusters.
