- CONCLUSION
- _________________________________________________________________________________________________________
- 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 problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
- LatencyMon has been analyzing your system for 0:30:52 (h:mm:ss) on all processors.

- CPU SPEED
- _________________________________________________________________________________________________________
- Reported CPU speed (WMI): 4201 MHz
- Reported CPU speed (registry): 420 MHz
- 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.

- MEASURED INTERRUPT TO USER PROCESS LATENCIES
- _________________________________________________________________________________________________________
- 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.
- Highest measured interrupt to process latency (µs): 23282.40
- Average measured interrupt to process latency (µs): 9.013998
- Highest measured interrupt to DPC latency (µs): 23277.90
- Average measured interrupt to DPC latency (µs): 2.930317
- _________________________________________________________________________________________________________

- ISR count (execution time <250 µs): 3355584
- ISR count (execution time 250-500 µs): 0
- ISR count (execution time 500-1000 µs): 0
- ISR count (execution time 1000-2000 µs): 0
- ISR count (execution time 2000-4000 µs): 0
- ISR count (execution time >=4000 µs): 0
- _________________________________________________________________________________________________________
- REPORTED DPCs
- _________________________________________________________________________________________________________
- 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.
- Highest DPC routine execution time (µs): 623.880

- DPC count (execution time >=4000 µs): 0
- _________________________________________________________________________________________________________
- REPORTED HARD PAGEFAULTS
- _________________________________________________________________________________________________________
- 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.
- 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.
- Process with highest pagefault count: nvcontainer.exe
- Total number of hard pagefaults 47926
- Hard pagefault count of hardest hit process: 20247
- Number of processes hit: 187
