  2. nothing  suspect,

    As it crash I was monitoring  ram, processor  and nothing special

    I use a macpro 2008 with 14g of ram and it works fine under windows7

    1. You’re segfaulting at random points. Run prime95 for a few hours to check if the system is really stable.

      You said you’re running Windows. Is this a virtual machine or via bootcamp?

  3. real machine

    I choose on startup wether it’s windows or mac osx

    I will try prime95

    Thanks by the way for your time

  4. ran the torture test for 17hours, no problem

    tried again to run DisplayCal. crashed the same …

    it seems  DC do not like the cocktail mix hard mac & soft windows

    was able to calibrate with i1

    HCFR works fine

    Thanks anyway

    1. Well, there’s something wrong with the system, either hardware, or software (drivers probably). Just run it natively under macOS.
