DPC latency problems

matecono · Nov 30, 2014

Hi!

I'm just having problems with the latency on my windows 8.1 enterprise..

here is my xperf https://www.dropbox.com/s/devas93nyy9i6yb/CPU.etl?dl=0

I tried everything but I can't solve this..

Thanks and sorry for my english, is not my native language:thumbsup2:

Hello,

Below is the CPU usage of one of the CPU cores on your computer (activity on the remaining 3 cores is pretty similar):

My suggestion is to try the following:

Use Task Manager to kill CCC.exe process (AMD Catalyst Control Center).
See if the issue disappears:
If it does:
Remove Catalyst Control Center application completely or try re-installing it.
If it does not:
Navigate to your BIOS and disable Extended C-States (it should be something called C3-State, Extended C-States, Power Manager or something similar).

Let us know the results.

it doesn't works.. I try to disable extended C-states but I can't find that option

I will try again to kill the CCC.exe

Could you make a few photos of your BIOS screens?

here they are!

thanks again!

Thanks.

There really doesn't seem to be a setting related to this.

Could you please generate a new XPERF trace using the command below, making CCC.exe is NOT running and you're experiencing audio problems:

Code:

xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER+IDLE_STATES -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular

Thanks.

Would you mind doing the following?

Open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.

Type the following command:

Code:

VERIFIER /QUERY & VERIFIER /QUERYSETTINGS

Paste the command output here.

Thanks. That's what I've expected.

Let's do the following:

Open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
Type the following command:
Code:
```
VERIFIER /RESET
```
Reboot the computer
Check if the issues still persist and, in case they do, generate a new trace.

Could you generate a new XPERF trace (making sure the issues persist during the capture)?

Sorry for delay getting back to you.

Could you please try installing the latest driver for your audio card from this page (you will need "64bits Vista, Windows7, Windows8, Windows8.1 Driver only (Executable file)").
