MagicAndre1981 Posted October 6, 2012 Author Share Posted October 6, 2012 ok, press Fn + F11to toogle the "Silent mode" does this make a difference? Link to comment Share on other sites More sharing options...
bruvau12 Posted October 6, 2012 Share Posted October 6, 2012 the silent mode makes no difference on or off. Will installing a different version of windows help with the problem? Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted October 6, 2012 Author Share Posted October 6, 2012 I thin think this is a hardware issue with your laptop.This site also mentions issues with the silent mode (look at the DPC checker tool picture) and CPU throttling:http://www.notebookcheck.com/Test-Update-Samsung-Serie-7-700Z3C-S01-Notebook.77437.0.htmlContact the Samsung support in this case.

3Seven Posted October 6, 2012 Share Posted October 6, 2012 this is ok. DPCs and interrupts are used by the system all the time so the values are ok.Are you sure? it wasn't there until recently, but i'll take your word for it. Thanks again for the help, it's appreciated.

Migun Posted October 10, 2012 Share Posted October 10, 2012 (edited) Hi Andre!First, I want to thank you for the tutorial, I am "banging my head" because of this problem.Whenever I use a torrent application (Utorrent, Tixati, etc) my computer freezes for 1 to 3 seconds from time to time.I have reinstalled Windows, removed the Anti virus, updated the network card (Realtek 8112L) driver among other things, nothing worked.I think the problem is in "tcpip.sys - function : TcpPeriodicTimeoutHandler"I uploaded the ETL (7z compressed )file to my dropbox folder and sent the link to you in a PM, if you have some time, I would be very grateful to you.Again, many thanks!edit: The Motheboard is a Asus P7P55D-E Edited October 10, 2012 by Migun Link to comment Share on other sites More sharing options...

I can see that the Rt64win7.sys is involved and this is the driver for your Realtek® 8112L Gigabit LAN controller. The driver version is from 2011 (7.046.0610.2011).

MagicAndre1981 Posted October 10, 2012 Author Share Posted October 10, 2012 the new driver fixed the large spikes:--------------------------DPC Info--------------------------Total = 21305 for module ndis.sysElapsed Time, > 0 usecs AND <= 1 usecs, 12695, or 59.59%Elapsed Time, > 1 usecs AND <= 2 usecs, 4188, or 19.66%Elapsed Time, > 2 usecs AND <= 4 usecs, 678, or 3.18%Elapsed Time, > 4 usecs AND <= 8 usecs, 759, or 3.56%Elapsed Time, > 8 usecs AND <= 16 usecs, 674, or 3.16%Elapsed Time, > 16 usecs AND <= 32 usecs, 876, or 4.11%Elapsed Time, > 32 usecs AND <= 64 usecs, 850, or 3.99%Elapsed Time, > 64 usecs AND <= 128 usecs, 499, or 2.34%Elapsed Time, > 128 usecs AND <= 256 usecs, 78, or 0.37%Elapsed Time, > 256 usecs AND <= 512 usecs, 1, or 0.00%Elapsed Time, > 512 usecs AND <= 1024 usecs, 7, or 0.03%Total, 21305Total = 3744 for module tcpip.sysElapsed Time, > 0 usecs AND <= 1 usecs, 1, or 0.03%Elapsed Time, > 1 usecs AND <= 2 usecs, 0, or 0.00%Elapsed Time, > 2 usecs AND <= 4 usecs, 1, or 0.03%Elapsed Time, > 4 usecs AND <= 8 usecs, 739, or 19.74%Elapsed Time, > 8 usecs AND <= 16 usecs, 2338, or 62.45%Elapsed Time, > 16 usecs AND <= 32 usecs, 426, or 11.38%Elapsed Time, > 32 usecs AND <= 64 usecs, 186, or 4.97%Elapsed Time, > 64 usecs AND <= 128 usecs, 47, or 1.26%Elapsed Time, > 128 usecs AND <= 256 usecs, 6, or 0.16%Total, 3744Does it also happen without "NetLimiter 3"?

Migun Posted October 10, 2012 Share Posted October 10, 2012 (edited) I will disable NetLimiter and test again.Thanks !edit: Some hours have passed, and nothing has happened, thanks for the Netlimiter tip Andre, you are trully magic !I just find it strange, Netlimiter just logs and limits the traffic.If it comes back (even with Netlimiter disabled) I will ask again for advice.Again, many thanks Andre !

MagicAndre1981 Posted October 11, 2012 Author Share Posted October 11, 2012 Some hours have passed, and nothing has happened, thanks for the Netlimiter tip Andre, you are trully magic !Again, many thanks Andre !the tool hooks into the network stack and such tools can cause issues. Nice to hear that it is fixed with the new driver and net limiter removed Link to comment Share on other sites More sharing options...
tuan Posted October 17, 2012 Share Posted October 17, 2012 hmm i don't have the option for 'summary table'? also, i don't think i have either the graph 'DPC CPU usage' or 'Interrupt CPU usage.' can someone help? Link to comment Share on other sites More sharing options...
