kasma Posted July 3, 2014 Share Posted July 3, 2014 (edited) Hey there, i am suffering from DPC drop outs, latency spikes.I tried to solve the problem, disabled not neccesarry hardware like wlan, etc.updated all the drivers. It kinda works when disabling the acpi.sys with process hacker but i still get drop outs from time to time.what makes it almost impossible to use the laptop for live music performances.I tried to log the data with xperf, but somehow i cant find the DPC CPU usage table..maybe i did something wrong.i also run the DPC latency mon wich results are that the laptop is not suitable for playing realtime audio.Its a samsung ativ 9 plus and i kinda get frustrated especially for the high price it was. i hope u can help me thanks a lot https://dl.dropboxusercontent.com/u/25112028/DPC_Interrupt_ACPI_BatteryController_Disabled.rarhttps://dl.dropboxusercontent.com/u/25112028/DPC_Interrupt_ACPI.SYS_supsended.rar https://dl.dropboxusercontent.com/u/25112028/1.jpghttps://dl.dropboxusercontent.com/u/25112028/2.jpg Edited July 3, 2014 by kasma Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted July 3, 2014 Author Share Posted July 3, 2014 you've sued the wrong SDK/WPT version. Make sure you use the 8.1 WPT if you use Windows 8.1 Link to comment Share on other sites More sharing options...
kasma Posted July 3, 2014 Share Posted July 3, 2014 Thanks, i installed the 8.1 SDK this time,it does look different but i couldnt manage to find the right graphs https://dl.dropboxusercontent.com/u/25112028/DPC_Interrupt_ACPI_Battery_disabled.rarhttps://dl.dropboxusercontent.com/u/25112028/DPC_Interrupt_ACPIBatteryDisabled_Processhacker_ACPI_suspended.rar Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted July 4, 2014 Author Share Posted July 4, 2014 the new WPA.exe tool sucks completely. Suspended is better (only ACPI.sy spikes between 128 usecs AND <= 256 usecs). With the battery disabled it is still over 1024. I can't really debug this from the ETL. You must disable devices until you find out which one causes it Link to comment Share on other sites More sharing options...
doveman Posted July 17, 2014 Share Posted July 17, 2014 Just made the move from AMD to Intel and it looks like I've got the same old problem with the network components of Windows causing latency problems. Not sure how to make a trace though, as I know I mustn't have LatencyMon running whilst I do that but without it I can't tell when it's spiked and I should stop the trace. In these screenshots, it spiked after about two minutes but I've restarted it and now it's been running for three and only hit 417us (which is still too high for my liking but LM says it's OK).

Andunemir Posted July 18, 2014 Share Posted July 18, 2014 Hi,I'm coming back with the usual combination of high DPC/sound stuttering in Windows 7 x64.It happened to me before and I managed to pin it down to AVG issues before. Uninstalled it and everything ran smoothly until a few days ago. I know I did some updates with my antispyware software and also with the Microsoft Anti-Malware but doing rounds of disabling stuff I haven't managed to correct the problem so any help would be most welcome.I've run xperf as I was told when I found the AVG issue and this is the file with the result: CPUI have a Toshiba Satellite with these specs:OS: Windows 7, x64Processor: Intel i7-3610QM @ 2.30GHzRAM: 16GBSound: Onboard RealtekVideo: NVIDIA GeForce GT 630MCheers!

Andunemir Posted July 18, 2014 Share Posted July 18, 2014 I can't download the file. I get a captcha with no text which I should enter That's weird, it works for me in all my internet browsers, logged in or not. Give it another try and let me know... Will try other site if it doesn't work. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted July 18, 2014 Author Share Posted July 18, 2014 compress the file as 7z/RAR amd upload it somewhere please, please. I doesn't work for me. Link to comment Share on other sites More sharing options...
doveman Posted July 20, 2014 Share Posted July 20, 2014 It seems quite clear from LatencyMon that the network components are causing the high latency. ndis.sys - 1.23ms NETIO.sys - 0.56ms, tcpip.sys - 0.33ms. The next highest is storport.sys - 0.20ms I don't know if it will capture anything, as I wasn't running LatencyMon at the same time so couldn't see what was happening but I left the trace running for three minutes before capturing it, so maybe it will show something helpful if you'd be good enough to take a look. https://drive.google.com/file/d/0B1fDI89phEESSC1rZzlBMnFUeUE/edit?usp=sharing Link to comment Share on other sites More sharing options...

You also have NDIS.sys DPC spikes. Also update /remove Panda (NNSHttp.sys). Edited July 20, 2014 by MagicAndre1981 Link to comment Share on other sites More sharing options...
doveman Posted July 20, 2014 Share Posted July 20, 2014 look for a driver update of the driver e1d64x64.sys (Intel network card driver) Thanks but I appear to already have the latest v12.11.96.1 dated 14/3/2014, which I got from the Asus website but is also contained in this under PRO1000/Winx64/NDIS64 https://downloadcenter.intel.com/detail_desc.aspx?agr=Y&DwnldID=21642 Link to comment Share on other sites More sharing options...
