_________________________________________________________________________________________________________
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. Also one or more ISR 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 0:02:20 (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3515 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): 18445.219945
Average measured interrupt to process latency (µs): 6.119495

Highest measured interrupt to DPC latency (µs): 1395.202658
Average measured interrupt to DPC latency (µs): 2.111052

_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

ISR count (execution time >=4000 µs): 0

_________________________________________________________________________________________________________
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.

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.

Process with highest pagefault count: svchost.exe

Total number of hard pagefaults 2044
Hard pagefault count of hardest hit process: 1428
Highest hard pagefault resolution time (µs): 442434.587482
Total time spent in hard pagefaults (%): 3.001105
Number of processes hit: 15

I'm a complete noob with PC's and was hoping someone can make sense of this and know how to fix it. In my BIOS all my CPU settings are on AUTO (stock default) I hope it can get fixed I just bought this and it's unplayable due to the constant throttling.

I also took a SS of my CPUID HWMonitor

If there's any more information you want about anything, screenshots etc just let me know and I'll post them. Thanks everyone

Download Speecy and check out your system with it.

spooky2th :

Hi spooky, thanks for the reply. I downloaded the program and I'm looking at all my system specs however I'm not too great with PC's and I'm unable to judge what causes the throttling by looking at my specs - Do you want me to screenshot any of the info and relay it back to you, I'm sure you'd have a much better understanding.

In Windows Control Panel > Power Saving Options > Power Plans, set the High Performance Plan >
In the BIOS: Check and Disable if necessary; The AMD C1E Support, AMD Cool & Quiet, CPU Smart Fan Control

spooky2th · Dec 30, 2015

I was interested in the CPU temperature and maybe the chipset temp too. If system is over heating, you might want to add a fan or two.

cbristow1 · Dec 30, 2015

Thanks for the reply again spooky - Here is an IMGUR of the temps: http://imgur.com/a/h5l4P

Chicano :

Thanks for the reply - I have down the power saving options. I'm not sure how to access them BIOs settings, I'm going to go have a try now. Will get back to you.

spooky2th · Dec 30, 2015

Those temps look OK. Nothing to worry about. You don't go into bios for those settings above. If you don't know how to get into "control panel," do a local search at the bottom left of the screen for it.

spooky2th · Dec 30, 2015

If you have any of the Gigabyte utilities installed, uninstall them and see. They are not needed and sometimes conflict with other programs.

Chicano · Dec 30, 2015

If the previous suggestions don't make a difference, Install HWiNFO > Run the Sensors, and upload an image of the Results sheet that includes the present CPU clock speed and voltage per core, general temperatures and other informative information.

Ah I made a typo. What I meant to put was that I have already changed my power setting to high performance and I will do the bios settings in a few minutes I'm currently running windows updates. Then I'll try uninstalling the gigabyte utilities - thanks again for the answers I'll update you shortly when I've done what you've recommended

cbristow1 · Dec 30, 2015

I'll do that also chicano - currently got 67 windows updates to do. :/

spooky2th · Dec 30, 2015

Were you having any problems before you tried the LatencyMon, app? If not, you might not have anything to worry about.

cbristow1 · Dec 30, 2015

I realised there was some problem with my system when I was trying to play csgo. I had very consistent fps at around the 250~ mark. It would be smooth however every 5-10 seconds it's has a stutter where I drop fps suddenly for about half a second to a second. After research I learned it's down to cpu throttling giving sudden fps drops consistently making it unplayable. Then I downloaded the latency app and it confirmed I had cpu throttle. Also when i got the fps spikes on csgo it would cut the sound and so on. http://youtu.be/EM4CaWHGsyQ here is a video showing the exact problem I got every 5-10 seconds. At the 12/13 second mark what he experienced is what I'm getting quite often.

spooky2th · Dec 30, 2015

I bet there's an app that is taking up your system's resources. Look in your system reports, error/problem reports and more. Event logs.

cbristow1 · Dec 30, 2015

I always close all my processes which are taking up anything over 10,000 memory in task manager before starting csgo and so on. I tried restarting my whole PC them loading csgo straight away so nothing is open which could be using my memory

spooky2th · Dec 30, 2015

Have you done a malware scan lately? Get the free malwarebytes and scan your comp. Don't need to try the free month of the paid for version as it will slow down your system too. Set the scan to look for rootkits too. Quarantine all it finds.

cbristow1 · Dec 30, 2015

The PC is brand new, It arrived yesterday and I installed windows and so on earlier today.

Here is the sensor info I got from HWiNFO
