    Same issue.

     

    System has 32GB but only see 2.7 GB in Synology.

    Found the error

    Fixed it by adding disable_mtrr_trim to the kernel options. Now I can utilize all available memory. This is probably a BIOS problem with my old GA-78LMT-USB3 FA Motherboard. There are no bios updates available.

    My server has 32GB RAM.

     

    In the TinyCore I can see all of them: 

    tc@box:~$ free -m
              total        used        free      shared  buff/cache   available
Mem:          31612         254       30195         603        1163       30255
Swap:          7875           0        7875


     

    But when in the synology I can see only 2GB instead of 32GB. 

    $ free -m
              total        used        free      shared  buff/cache   available

    Because of this I cannot run a VM. Synology says that it doesn't have enough memory.

    But in settings app of synology, I can see 32GB, but 29GB are marked as reserved.

    What am I doing wrong?

     

     

    Same issue.

     

    System has 32GB but only see 2.7 GB in Synology.
