ga-970a-ud3 rev 1.2 DPC latency

[devor]

Hello everyone I have a problem with my computer I hope you can help me because I'm out of ideas.

motherboard
gigabyte ga-970a-ud3 rev 1.2
cpu
phenom ii x3 720 be stock settings
hard disk
ssd 250 gb Samsung evo
power supply
corsair 650 w
ram
2x4gb ddr3
video card
ati 7770 hd 1gb vram
os windows 7 ultimate 64 bit genuine with service pack and amd video drivers installed from website

during the utilization of this machine I have noticed for a while that it is "microstuttering" for example I drag a window around the screen and it's not smooth or I'm watching a video with vlc media player or mpv media player or in chrome or firefox in youtube and it is not smooth and pleasant to watch. also sometimes (but not always) the audio crackle and pop. this problem happens randomly as it can happen after 15 or 67 or whatever minutes and manifest for short or long period of time.
The temperatures are always cool both on cpu and gpu and hard drive they are maxing at 40 ° Celsius.
I have researched for weeks what the cause of this would be and I have read about dpc latency software which monitor the system during utilization to see how it performs and I have noticed huge spikes regarding process ataport.sys

please see following link for clarity

I have tried many things based on general suggestion read from google ectetera such as :
1) installed any bios version available on the motherboard webpage, including latest beta and non beta
2) installed windows 7 with ide setting in bios and not loading any driver
3) installed windows 7 with ahci setting in bios and not loading any driver
4) installed windows 7 with ide setting in bios and loading the driver available in the motherboard support site
5) installed windows 7 with ahci setting in bios and loading the driver available in the motherboard support site
6) installed chipset drivers from motherboard support site after windows installation was completed
6.1) allowing windows update to install whatever it thinks is necessary for this system
6.2) blocking completely windows update to install nothing and not touching the drivers
7) tried another power supply
swapped the cable that connects the ssd (i have 3 pairs of cables)
9) tried connecting the ssd in every sata port available
10) installed chipset drivers from Gigabyte website
11) installed chipset drivers from AMD website
12) tried a mechanical drive
13) disconnecting my dvd player and leaving only the ssd as only drive in the system
14) disabling every usb ports or network integrated card from device manager as suggested by dpc latency software developers to see if this solves the spikes, unfortunately, it does not.

i would also like to point out that the ssd software is not working fully (i cannot enable rapid mode) but benchmarking the drive gives good speeds please see imgur link

please let me know if you have any suggestion thank you very much and happy holidays everyone

what tells the error log? excessive entries?

Additionally,  what about trying an updated graphics driver?

First of all thanks guys for checking this thread I really appreciate.

during the last couple of days I have as usual been tinkering with this machine to try and fix it by mixing and matching various drivers from different eras and trying a program called process lasso which, according to the developer should benefit any system and I thought, hey maybe this could improve the situation.
this program adds a new power plan option to the system called "Bitsum highest performance" and in theory should remove my doubt I had about different power plans but I have to say I see not very much improvement.
Im also using the latest graphic driver you posted and downloaded the extra chipset driver and run the setup.exe.
I also have "splitted" my hard drive cable from the dvd burner so they now have their own cable connected to sata ports and power supply, while before I was using a single cable.
I have forgot as you pointed in your reply to post the log (sorry) so here it is a new one been running for a while.

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  0:58:09  (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.

Highest measured interrupt to process latency (µs):   25457.880780
Average measured interrupt to process latency (µs):   3.785217

Highest measured interrupt to DPC latency (µs):       5233.390243

 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:                 iexplore.exe

Total number of hard pagefaults                       820
Hard pagefault count of hardest hit process:          210

I was talking about the windows error log (event viewer) and see where it lists many errors of same type.

[devor]

there are no errors in event viewer

found some updates apparently newer than what my system installed I'm gonna try them

there are no errors in event viewer..

You are sure your win7 error log looks like this at least for the last hour?

yes there are no errors

You installed the current audio driver?

version 10.1200

if no joy I think it's time for a new mobo... since you already clean installed win7?!

[shadowsports]

Does DXDIAG yield anything?

[devor]

To my surprise I've managed to find that Virtualbox was the culprit . Searching around i've read that a lot of people had same issues as me with dpc graphs very similar (although developers closed bugs regarding this as fixed) and now I'm using VMware Player and ... everything is working good again no more broken animations or sound skipping.

Thanks for chiming in during this painful days really appreciated your suggestions and support

Thumbs up to that.  The 970 was a great series in its day.  Dated now.  It still works, but maybe he'll consider an upgrade come the new year.
