Hi All,

I've just installed Proxmox for the first time.

I am having an issue with datacenter only displaying half of the ram I have installed, I have checked the Bios which is showing correctly, I've even changed the ram out.

I'm not using any storage, are there any suggestions?

Thank you in advance.

Hi,
please try to check if your system correctly detects your RAM modules.
dmidecode --type 17 should give you some information.

your provided output shows 4x 4GB Memory modules.
My counter-question would be:
  • Are you expecting more?
  • What should be in there?
  • What does your BIOS show?

Looking through the summary half of my ram is showing as swap which I do not want, I only have 4 containers and 3 VM's. I've tried removing swap but it doesn't then go back into normal ram.

Any suggestions

Please post the output of free -h.
Do you use some ram based swap device? Please post also the output of swapon --show.
You can disable all swap by running swapoff -a. This will however not remove the swap partition.
Are we really talking about the ram or are you referring to the storage memory?
It seems strange to me that you would have half of your ram reserved as swap device, especially since you stated this is a fresh install.
