Hallo ich habe gerade erst Windows 10 neu aufgesetzt und habe nun mit LatencyMon die DPC Latenzzeiten überprüft. Könnte mir jemand sagen ob die soweit ok sind? Was etwas seltsam ist das LatencyMon Windows 10 als Windows 8 erkennt. Und bei der CPU Frequenz nur 1mz erkannt. Obwohl die CPU auf 4,3hz übertaktet ist und alle c-states ausgeschaltet sind. Core temp zeigt aber soweit alles normal an. Ist das einfach nur ein Fehler in LatencyMon ? Sind die DPC Werte ok?

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3503 MHz
Measured CPU speed: 1 MHz (approx.)
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.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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): 115.744327
Average measured interrupt to process latency (µs): 1.761449
Highest measured interrupt to DPC latency (µs): 114.575192
Average measured interrupt to DPC latency (µs): 0.570369

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.
Process with highest pagefault count: svchost.exe
Total number of hard pagefaults 20013
Hard pagefault count of hardest hit process: 12969
Highest hard pagefault resolution time (µs): 1031780.852698
Total time spent in hard pagefaults (%): 0.410085
Number of processes hit: 14
