Hey, I have an Optiplex 7010 which I am solely using with Proxmox for VMs. It came with 4GB memory and I have bought two 8GB sticks from Corsair (this is the specific model).

I've installed and it told me it needed to check the memory as it had been changed. I said yes, and it run. OK, however, it only recognises each stick as having 4GB (i.e. half the size). Now I know this model supports up to 16GB, but even looking at the BIOS or my Proxmox install, it only shows as having 8Gb installed.

I thought it could be an old BIOS so I upgraded it to the latest version but it didn't change the amount of memory it shows. I've read through a lot of other posts here where people report the same issues but nothing seems to work for me, so wondering if any of you can help?

Thanks in advance
