Hi Nickleldome,
Thank you for helping with this. I did what you asked and I ran LatencyMon for 30 mins with Cubase open. ISR and DCP stayed low as far as I could tell but I did hit 2707 Hard Page Faults.
2 other things I noticed was LatencyMon recognised my machine as Windows 8 even though it has been upgraded to Windows 10 which was odd. It didn’t measure the CPU speed correctly either, C-State and Speedstep are both disabled and Turbo is enabled in the BIOS.
My results are below -
CONCLUSION
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:30:00 (h:mm:ss) on all processors.
SYSTEM INFORMATION
Computer name: MUSIC
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: All Series, ASUS, ASUSTeK COMPUTER INC., Z97-A
CPU: GenuineIntel Intel(R) Core™ i7-4790K CPU @ 4.00GHz
Logical processors: 8
Processor groups: 1
RAM: 24517 MB total
CPU SPEED
Reported CPU speed: 3998 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): 54.815812
Average measured interrupt to process latency (µs): 2.263825
Highest measured interrupt to DPC latency (µs): 53.278921
Average measured interrupt to DPC latency (µs): 0.994895

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.
