    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

    "NumberOfWinProcessorsRequest"= divide the value by 2

    Make sure you enter the value in decimal (not in Hexadecimal).
