Hola buenas a todos.
Llevo un par de dias intentando optimizar el pc en tema de drivers y tal y necesitaria una mano con ciertos temas de lo que no tengo mucha idea .

He hecho varios analisis con LatencyMon y (aunque el que voy a poner es de 3 minutos, los de varias horas dan los mismo tiempos de latencia aunq el numero de hard pagefaults aumenta drasticamente ) tengo ciertos problemas con el hard pagefault resolution time, con la latencia del nucleo 0 del procesador y con el measured kernel timern latency.

Mi placa soporta la ultima generacion de intel pero es bastante baratilla, es posible que haga algo de cuello de botella pero no creo que sea taaanto como para disparar las escalas de latencia no?

Os dejo un copia y pega de las Stats

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.

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.

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 0:51:27 (h:mm:ss) on all processors.

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.

Average measured interrupt to process latency (µs): 2,557049
