  1. high DPC from Usbport.sys 1.0 and 2.0


    I've been getting a lot of "DCP count" when I connect my mouse to a either a 3.0 or a 2.0 USB port. I ran latencymon and everything comes back really good except a driver called Usbport.sys, it has the highest execution times, DPC count, and ISR count. When I unplug my mouse (razer deathadder 2013) everything is perfect. I've tried every port on my PC, installing windows both 10 and 7, installing bios drivers, and chipset drivers and bought a new mouse. Here are my latencymon stats: https://justpaste.it/47o2t

    If anyone has any suggestions or solutions I'd be really grateful! THANKS!

    High DPC/ ISR Latency

    Hello community,

    So by way of background, for a while now I have experienced issues regarding audio crackles and pops. This primarily occurs when using Cubase 9.5 but also exists outside of the software too, occasionally. After searching for solutions, I came across LatencyMon
    and decided to start testing (the results of which can be found below). I should add that when trying it for the past few days, I have noticed that the 'Highest measured interrupt to process latency' changes between HDAudBus.sys and Wdf01000.sys.

    Steps I have taken so far:

    1) The first thing I did was simply to plug out all of the USB devices that were inserted in my computer one by one. One potentially notable piece of information is that I switched audio interface very recently - from the Focusrite 2i2 to the Audient iD4.
    However, I experienced these issues with my last audio interface too. This step produced no differences.

    2) I then, through device manager, disabled a huge variety of drivers one by one to see if there was a particular driver causing the issue. This primarily included network, audio and USB drivers. This step produced no differences.

    3) Following this I downloaded Driver Booster and tried to update all outdated drives, of which there were many. This step produced no differences.

    Pretty sure there were a few other minor things I have tried too such as disabling WiFi, antivirus and more. All produced no result.

    More than happy to provide more details if necessary. Any help is greatly appreciated.

    High DPC latency (especially ndis.sys and tpip.sys)


    I've had a problem with DPC latency for several months (craks/pops/random dropouts when listening to music/sound). I recently found out about LatencyMon and let it run for about 15 minutes. The result is pasted below. I'd appreciate if you could suggest what to do next.
    Am I correct in understanding that the latency caused by ndis.sys and tpip.sys happens because I'm using a WiFi network?

    Thanks in advance for your help.

    LatencyMon result:






    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. 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.

    high DPC from Usbport.sys 1.0 and 2.0

    Intel Updates Core 2 Quad Q9550 to E-0 Stepping

    We continue our Monday news list with another Intel story that brings to our attention information concerning the company and more specificly its 2.83GHz Core 2 Quad Q9550 chips that will move from the current C-1 to the newer E-0 stepping. The updated chips will start selling on August 22nd, featuring the following changes:
    • New SSpec and MM numbers for the converting products
    • CPUID will change from 0x10677 to 0x1067A
    • Package change to Halide free package
    Apart from that, the new stepping CPUs will not include any other changes. Of course, like most new stepping parts a BIOS update will be needed.
