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!
Try it and see what happens. Often the maximum on prebuilts isn’t the maximum that the hardware will support. My last laptop claimed 32gb maximum ram but works fine with 8+32gb. Just be aware that it might not work and have an option to return or sell the ram on if it doesn’t.
Edit: frequently on older hardware the memory controller can’t address more than a stated maximum amount of memory. This hasn’t really been an issue for a while, but like others mentioned you might not be able to see or use memory beyond that limit. Or the machine will just fail to POST. Always test unsupported memory configurations overnight (at least) with something like memtest86 before trusting them with any important data.
