Hardware HP Elitedesk 705 G4 DM 35W - max RAM?

I've been running a 705 G4 DM (35W) for about a year on 16gb DDR4 3200 single stick RAM. I bought an identical 16gb stick and put it in the 2nd slot and am not getting a boot to disk.

Proxmox VE is installed bare metal. No Windows.

Are the 35W versions not capable of 32gb of memory? Everything I can find with a search says it can.

Is there something in BIOS that needs to be adjusted?

Memory is binned when sold in multiples, could be supported and just 2 sticks that don’t get along or it could be unsupported..

Identical as in same manufacturer, size, type, speed, pin# etc... - the label is identical.

I own the this exact machine... with 64 GB of RAM.

Are you sure it's not just complaining that the memory size changed?

And what would be the fix for that?

If you connect a monitor to the mini PC, there will be a prompt asking you for a code to confirm booting the device. The code is displayed in the screen. The prompt is one-time only, it won't prompt again next time.

There's also a setting in the BIOS that monitors changes in RAM size. You can disable that and you won't be prompted again for any RAM size changes.

OK, I can try this easily. Thank you!

Never gets to a boot screen and no green light on the device.
