Solution 3. Check Graphics card

“DPC Watchdog Violation” may also appear when your graphics card is modified, too much overclock/underclock setting, driver problem or it is faulty. This error can be fixed by the graphics card situation. However, faulty graphics can only be solved by removing it to the system and send it for warranty. Graphics card unit has 2 to 3 yrs warranty.

  1. If you modify the graphics card BIOS, make sure it is comfortable with the tweak. This is common to a moded AMD graphics card that mines cryptocurrency. Mostly, this is due to incorrect memory timing, too much memory overclock and too much under-volt. To fix this reflash the original BIOS, then tweak it again.
  2. If you are using an overclocking tool, set the setting to default and look for the comfort zone of the video card. Also, make sure the fan in the overclocking tool is set to manual, that would not let the temperature over 85-degree Celsius at max load.  However, if you are into crypto mining make sure the temperature stays below 70 -degree Celsius at max load. Again, in crypto mining, too much memory overclock, under-volt and power limit may also cause the error.
  3.  Make sure your power supply unit (PSU) could handle the max load of the graphics. In crypto mining, power supply unit (PSU) may also cause the “DPC Watchdog Violation.” It is due to PSU is faulty, overheating and too much current running on the PSU SATA and PCI-E cable. PSU SATA cable should only support at least two GPU riser, while for PCI-E cable should only support at least two graphics card. Avoid using extender cable, it is commonly caused by burns.
  4. Setting the PCI-E lane to different Gen in the BIOS may also fix the problem.
  5. If the issue persists, reinstall the driver using the latest driver.
  6. However, if reinstalling the driver failed. A hardware could be faulty, it could be the PCI-E slot of the motherboard or the graphics card. For a crypto miner, it is possible that the graphics card PCI-E risers could be faulty. Also, check for burns in your power supply unit (PSU) and graphics card PCI-E risers.
