MSI installer service causing high DPC spikes. Automatic updates breaking any transcoding process RRS feed

  • General discussion

  • I have been logging DPC latencies during all MSI based installations incuding updates from Windows update and the result is allways the same any MSI instance will cause a DPC spike up to 100.000 micro-seconds resulting in a sound/video cut with any transcoding process runing at once. I have tried fresh installs without any software of both Windows 7 64-bit and 32-bit in different computers with very different hadware configurations and the result is allways the same automatic updates and other MSI based installations will cause cuts in any media streaming/transcoding being played at once. Is there any upcoming update for this ?? Is it a known issue??

  • Hi FJTORSOL,

    What's the model of your motherboard? Update the BIOS to the latest one.

    Also update sound and graphic card driver. Then check if the issue persists.

    If it doesn't work, please provide us with the detailed information of your computer configuration.

    Regards,

    Miya

  • No it's no just a motherbouard or a computer it's every computer that uses Windows 7 64-bit and 32-bit. It's not just a faulty Gigabyte motherboard or any networking device it's just how MSI installer service is implemented in the system and the way it access the information to validate an installation before starting. Anyway I have tested systems with Intel processors an chipsets (from a P4 to a Core i7) an AMD system with a NVIDIA motherboard the Intel models include laptops and desktops where curiously XP (32-bit) never showed such bug.

  • Windows 7 is not accepting suggestions or bug reports...

  • And the problem continues with Windows 8. It is difficult to understand where all the engineering efforts go when removing features and simplifying an operating system does not reduce the increasing number of performance glitches...

  • install the WPT and run a xperf trace to capture the DPC usage:
