From LatencyMon:
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 or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem
appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:01:15 (h🇲🇲ss) on all processors.

Computer name: STUDIO
OS version: Windows 10, 10.0, version 2009, build: 19042 (x64)
Hardware: Z390 AORUS PRO, Gigabyte Technology Co., Ltd.
CPU: GenuineIntel Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz
Logical processors: 12
Processor groups: 1
RAM: 32700 MB total
_
CPU SPEED

Reported CPU speed: 3696 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): 2050,50
Average measured interrupt to process latency (µs): 3,870344
Highest measured interrupt to DPC latency (µs): 2045,80
Average measured interrupt to DPC latency (µs): 1,612681

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.

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.
