_________________________________________________________________________________________________________ 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 0:02:44 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: FRACTAL-PC OS version: Windows 8 , 6.2, build: 9200 (x64) Hardware: ASUSTeK Computer INC., Crosshair IV Formula CPU: AuthenticAMD AMD Phenom(tm) II X6 1090T Processor Logical processors: 6 Processor groups: 1 RAM: 12286 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 3725 MHz Measured CPU speed: 18 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): 23934,047484 Average measured interrupt to process latency (µs): 12,188956 Highest measured interrupt to DPC latency (µs): 187,733357 Average measured interrupt to DPC latency (µs): 3,337555 _________________________________________________________________________________________________________ REPORTED ISRs _________________________________________________________________________________________________________ Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

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: backgroundtaskhost.exe Total number of hard pagefaults 95 Hard pagefault count of hardest hit process: 75 Highest hard pagefault resolution time (µs): 27757,680537 Total time spent in hard pagefaults (%): 0,004454 Number of processes hit: 2 _________________________________________________________________________________________________________ PER CPU DATA _________________________________________________________________________________________________________ CPU 0 Interrupt cycle time (s): 7,617868 CPU 0 ISR highest execution time (µs): 53,895302 CPU 0 ISR total execution time (s): 0,069559 CPU 0 ISR count: 10085 CPU 0 DPC highest execution time (µs): 454,919732 CPU 0 DPC total execution time (s): 1,976609 CPU 0 DPC count: 475177 _________________________________________________________________________________________________________ CPU 1 Interrupt cycle time (s): 2,363971 CPU 1 ISR highest execution time (µs): 8,360805 CPU 1 ISR total execution time (s): 0,000354 CPU 1 ISR count: 84 CPU 1 DPC highest execution time (µs): 72,395973 CPU 1 DPC total execution time (s): 0,095546 CPU 1 DPC count: 7352 _________________________________________________________________________________________________________ CPU 2 Interrupt cycle time (s): 2,375957 CPU 2 ISR highest execution time (µs): 0,0 CPU 2 ISR total execution time (s): 0,0 CPU 2 ISR count: 0 CPU 2 DPC highest execution time (µs): 135,119463 CPU 2 DPC total execution time (s): 0,100836 CPU 2 DPC count: 6185 _________________________________________________________________________________________________________ CPU 3 Interrupt cycle time (s): 1,573694 CPU 3 ISR highest execution time (µs): 0,0 CPU 3 ISR total execution time (s): 0,0 CPU 3 ISR count: 0 CPU 3 DPC highest execution time (µs): 66,845638 CPU 3 DPC total execution time (s): 0,025369 CPU 3 DPC count: 2198 _________________________________________________________________________________________________________ CPU 4 Interrupt cycle time (s): 1,146066 CPU 4 ISR highest execution time (µs): 0,0 CPU 4 ISR total execution time (s): 0,0 CPU 4 ISR count: 0 CPU 4 DPC highest execution time (µs): 70,141477 CPU 4 DPC total execution time (s): 0,006309 CPU 4 DPC count: 588 _________________________________________________________________________________________________________ CPU 5 Interrupt cycle time (s): 1,119657 CPU 5 ISR highest execution time (µs): 0,0 CPU 5 ISR total execution time (s): 0,0 CPU 5 ISR count: 0 CPU 5 DPC highest execution time (µs): 62,437852 CPU 5 DPC total execution time (s): 0,055310 CPU 5 DPC count: 3609 _________________________________________________________________________________________________________
