    Guys with memory problems add this to the grub.cfg

    disable_mtrr_trim

    Example: 
      

    
set common_args_3617='disable_mtrr_trim syno_hdd_powerup_seq=0 HddHotplug=0 syno_hw_version=DS3617xs vender_format_version=2 console=ttyS0,115200n8 withefi elevator=elevator quiet syno_port_thaw=1'

    Now I got:

                       total        used        free
    Mem:          16034         260       15458           3         315       15560
    Swap:         11665           0       11665


    /proc/mtrr is editable even from a command shell: you can disable register records and/or write new values there this seems to be a Bios bug.
    Adding disable_mtrr_trim disables it without losing any performance as far as I know.

     

    Thank you for this great tip ! It's now working fine on my baremetal N54L !

     

    However I suspect that DSM would be able to use the amount of RAM reserved for graphic card purposes (specified in the BIOS) which could lead to some issues ?

    It may be safer to buy a dedicated graphic card ? :(

    More about C1E :

     

    Quote

    C1E is a power management state that allows the processor to reduce power beyond just the cores. With C1E, the processor power can be reduced by lowering the memory controller clock speed and halting the HyperTransport™ technology links. This new feature was extremely important for our 12-core processors with the increase in memory channel support as well as the increase in HyperTransport™ technology links within the design.

     

    Quote

    The C1 enhanced state (C1E) is a stop-grant state supported by the processor. The C1E state is characterized by the following properties:

    • All cores are in the halt (C1) state.
    • The ACPI-defined P_LVL3 register has been accessed.
    • The chipset has issued a STPCLK assertion message with the appropriate SMAF for C1E entry. Note that [The ACPI Power State Control Registers] F3x[84:80] specify the processor clocking and voltage behavior in response to the C1E SMAF.
    • The processor has issued a STOP_GRANT message to the chipset.

    General requirements for C1E:

    • The ACPI-defined C2 and C3 states must not be declared to the operating system.
    • C1E should only be enabled when the platform is in ACPI power management mode.

    +7 for AMD support

    I think there is still plenty of people having the older HP Gen7 with AMD as it is small and fast enough for NAS.

    Using ESXI is possible, but I need to sacrifice one disk for VM Datastore instead of using it for data.

     

    +8 for AMD Support

    I've got 2 Gen7 at home
