  1. System must be booted in MassCore mode
  2. Go in MT Security panel and note your current CPU configuration.
    Depending on your MassCore authorizations, the number of Cores might differ.
    If you don't have the MassCore SMP key ("SMP key not present" message),the number of Cores for MassCore will always be 1.
  3. Go in BIOS and disable HyperThreading (see motherboard configuration guide for details)
  4. Reboot the system, but with the standard Windows boot line (non Masscore)
  5. Go in Windows registry (regedit)
    Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\RTX64
  6. Values in DECIMAL
  7. "NumberofProcessorsEnabled" : divide the value by 2
  8. "NumberofRtssProcessorsRequest" divide the value by 2
    "NumberOfWinProcessorsRequest"= divide the value by 2


    Make sure you enter the value in decimal (not in Hexadecimal).
    See the table below for examples.
    "NumberofRtssProcessorsOnline"  : do not modify this value.


  9. On a ''N'' Core NON Hyperthreaded : ''N''-1
    On a ''N'' Core Hyperthreaded : ''N''-2
  1. Go in System Configuration (msconfig) > Boot tab
    Select the MassCore line, then click on Advanced options
    Set Numbers of processors to the same value as WinProcessorsRequest above.

    (i5-8400, i5-8500,....)
    6 Cores
    Hyperthreaded
    (i7-8700, i7-8700k,...)
    Number of Cores
    in non MassCore mode
