    Win 8.1


    Hello, I've had a similar issue, just fixed it, a driver memory leak.
    Out of 32 GB, 30 GB were In Use in Task Manager or Resource Monitor, but apps were using much less.
    Using RamMap I saw that 22GB were in Nonpaged Pool.
    Using Driver Verifier I saw an unsigned driver, applecharger.sys and my issue was caused by it.
    It was installed by ON/OFF tool ver. 2 from Gigabyte mainboard, AppCenter.
    See here:
    page fault in nonpaged area (applecharger.sys) error - Microsoft Community

    After uninstalling On/Off all returned to normal, 8GB In Use

    Oh, i actually solved my problem with memory leak. It was a fault of ESET Smart Security. I was just trying to eliminate everything somehow affecting in/out traffic, obviously uninstalling firewall seemed an option as good as any other. So, I uninstalled it and even before restarting PC i've noticed, that Non-paged pool have stopped to grow.

    Everyone, thanks for all the advices, be aware of the ESET behaviour on Win8. You'd probably want to change it, at least until it's fixed.

    A quick and easy fix you should try first.....


    I recently purchased ASUS CG8480 ROG gaming PC with 16 MB of RAM. Shortly after installing Win 8.1 upgrade I realized I had a memory leak issue. I sifting through countless forum pages, reset browsers, disabled ndu.sys -downloaded the windows development kit to get Poolmon.exe yet the problem either remained or I created an entirely new problem. I have included a link to the website for the free open source Driver Pack Solution Software which found and updated 15 drivers on my system in about 5 minutes
    DriverPack Solution >> Best Drivers installation Software restarted and voila, no more memory leak!

    I am in no way affiliated with this software nor is this a cloaked malware advert, I just wanted to save someone else the headache that I experienced. I used the 14th edition (couldn't find it on the website) of the software which supports the April 2014 and earlier update of Win 8.1

    My PC is now purring along using 23% of RAM and has been running for over 24 hrs and I have my sanity back

    Windows Network Data Usage Monitoring Driver - Windows 8 Service

    This service provides network data usage monitoring functionality.
    This service exists in Windows 8 only.
    Startup Type

    Windows 8 edition without SP
    Core Automatic
    Professional Automatic
    Enterprise Automatic
    Default Properties

    Display name: Windows Network Data Usage Monitoring Driver
    Service name: Ndu
    Type: kernel
    Path: %WinDir%\system32\drivers\Ndu.sys
    Error control: normal

    Default Behavior

    The Windows Network Data Usage Monitoring Driver service is a kernel mode driver. If the Windows Network Data Usage Monitoring Driver fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the Ndu service has failed to start.

    To Fix Memory Leaks on Non-Paged-Pool:
    Changed the registry value instead of using Autoruns:

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu

    Change the Start value to 4 (for disable).

    After a lot of months looking for solutions i finally found mine and i hope others can fix their problems with this.

    Thanks everyone for their help.
    i've been having a huge issue and i think this may have solved it for me..my memory after doing this dropped from 80% (while only on desktop or limited in chrome) to 15% (with same usage)..hopefully this is the fix and i don't have to deal with this anymore! thanks so much.

Since these tags in and of themselves aren't called by the OS to this level, something running on the machine is likely hammering the network stack. Also, since I don't see any indication of which process, it's likely going through typical OS binaries (like wininet.dll or winhttp.sys) to make it's network calls. I can see you have quite a bit of networking software on the box - mDNS, probably from iTunes or other Apple software, No-IP, a torrent client, and something called the Qualcomm Atheros Killer Network Monitor (remember one of the tags was the network monitoring one?). That last one is a major suspect, as is the torrent client. I would recommend disabling ALL of these applications, especially the Qualcomm software and the torrent client, and reboot and monitor. If the problem persists, get more data - otherwise, re-enable things one at a time until the problem comes back.

    Given the tags and binaries called out by the trace, I'd wager it's either the Qualcomm software directly, or it's behavior with the torrent client running, that's causing this. However, anyone can guess, and I prefer data. Let's see what happens with the recommendations I made.
    Thanks a lot cluberti! I was having this same problem, read through the thread, disabled the Qualcomm Atheros Killer Service and set it to "manual", restarted, and it's fixed!!

    Hi everyone. After reading through this and it leading me to the exact problem with the Qualcomm driver I thought I would post.

    The leak with the driver comes with the bandwidth control (or at least for me it did). Simply open your killer network manager from the system tray, click network and untick enable bandwidth control and restart your computer. I monitored an increase in the non-paged pool of about 1mb every 3 seconds while downloading a game when bandwidth control was on and after turning it off and restarting it hasn't increased.

    Hello. I have never posted on this forum but I just registered a username to say THANK YOU VERY MUCH Spellbound, this fixed it for me. For some reason I noticed my RAM usage was high. Did some research and found this forum thread. Went to last page, saw your post, unchecked Bandwith Control on the Killer Network Manager, it dropped from 61% usage (9GB non-paged memory) to 14% (122MB non-paged memory).

    Again, thank you so much

    hello,

    i also seem to have the memory leak problem. i have 6gb ram and at this moment it is using 55% of it while i'm onlying using chrome.

    My drivers are up to date.
    I did a complete new installation of windows on sunday.
    I tried to change te Ndu settings: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu
    I checked out the box that says my pc can turnoff the wifi to save power.
    I ran Rammap and it looks like i don't have a high non-pagedpool.
    I can't finf the intellimem.exe file, so i don't think it's on my pc.

    I can not find the problem and the sollution, is there any other thing i can try to solve this? It's getting really annoying at this time, cause when i'm playing games, the pc is shutting down the games because according to the pc the memory is too low.
