  7. CONCLUSION
  8. _________________________________________________________________________________________________________
  9. Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
  10. LatencyMon has been analyzing your system for 0:04:10 (h:mm:ss) on all processors.

  30. Reported CPU speed (WMI): 3801 MHz
  31. Reported CPU speed (registry): 380 MHz
  32.  
  33. Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

  37. MEASURED INTERRUPT TO USER PROCESS LATENCIES
  38. _________________________________________________________________________________________________________
  39. The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
  40.  
  41. Highest measured interrupt to process latency (µs): 122351.20
  42. Average measured interrupt to process latency (µs): 4112.605884

  49. REPORTED ISRs
  50. _________________________________________________________________________________________________________

  70. REPORTED DPCs
  71. _________________________________________________________________________________________________________
  72. DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.
  73.  
  74. Highest DPC routine execution time (µs): 147346.640
  75. Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 576.88 , NVIDIA Corporation

  90. _________________________________________________________________________________________________________
  91. REPORTED HARD PAGEFAULTS
  92. _________________________________________________________________________________________________________
  93. Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
  94.  
  95. NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
  96.  
  97. Process with highest pagefault count: system
  98.  
  99. Total number of hard pagefaults 5900
  100. Hard pagefault count of hardest hit process: 1372
