Performance Problem - Memory Management
Aug 22, 2009
I just installed windows 7 rtm 64bit and I really love it. But i got a performance problem under certain circumstances and hope u can help me
First, here is a list of my relevant hardware:
AMD X2 4200+ @2.7 GHz
3 GB DDR RAM
System drive: 2 x 250 GB (raid 0, about 90 MB/sec reading)
graphics: 9800gt
2 USB Flash drives dedicated to Ready Boost (2 GB and 512 MB)
Now let me describe my problem: I have to run 10 virtual machines on this PC. I use VMWare Server, each virtual machine is set to 128 MB RAM (lowest value possible, any lower values result in excessive swapping). All virtual machines are set up on another harddrive (200 GB, about 40 MB/sec reading), so they don't affect my system drive.
Performance is normally just fine in Win 7 (the virtual machines eat up very little CPU power). But when i use very demanding applications, e.g. Crysis, performance becomes a nightmare (framedrops, game is not playable). The LEDs for my flashdrives and my harddrive are flashing all the time. I guess all my Ram is used and win 7 swaps the data needed for crysis instead of swapping my virtual machines. Only way to play crysis is to stop my virtual machines (which is not acceptable).
In Win XP that wasn't such a big problem, there was some swapping for about 1 minute when i started crysis, then performance was just fine.
Any hints?

I've been using Windows 7 now since 6th of May, and love it! I haven't had any troubles except 2, but this topic is meant for only one.
I remembered an application called Everest, it lists all of your hardware and information about it, OS and stuff, really nice. It also has tab for sensors, where you can monitor temperature.
When i was looking around in Everest, I found out somehow 7gigs. of virtual memory is available, and most of the time somewhere around 2gig. is being used. That was kind of weird, because I have 4 gigs of RAM, and most of the time only 25% is used of it. So, why would Windows prefer use of the virtual memory over the use of physical memory? I found out virtual memory could be managed in "advanced system settings". because 2.5 gigs of virtual memory was used most of the time, I thought: why not just completely disable paging file.
So it's: computer --> right click properties --> advanced system settings --> advanced tab --> performance --> settings --> virtual memory --> change.
So finally comes the problem, I have successfully disabled the paging file, and it says "total paging size for all drives: 0 mb". But when I go to Everest, it still says I have 7 gigs of Virtual Memory available, and it uses 2 gigs. I want to make full use of my physical memory!

I'm new to this community and not the most computer savvy person, but I've been having this error for a while and it's starting to bug me. We recently got a new computer but as I start to use it, I'm noticing a lot of crashes and blue screen. Of the errors I've noted, the major one seems to be the "MEMORY_MANAGEMENT" blue screen. I'm currently running Windows 7 64-bit and I have about 16G of memory installed.I did some preliminary research and many topics suggested either pulling sticks out (which I do not know how to do), posting minidump file (attached), and running a memory test (I just ran it for 12+ hours and it still did not finish, but I need to use my computer).

After previously solving the BSOD error "a clock interrupt was not received on a secondary processor within the allocated time interval" by replacing the CPU, I have run into another BSOD. This time the error is "memory management". After doing some research I'm thinking this error is about some program conflicts or something similar (I'm hoping that is the case!), instead of a hardware problem. I have attached the last 3 minidumps I have.

I started to get random BSODs, usually after a few hours after turning on my PC. The only major change I made was a firmware upgrade to my Asus P8Z68-V Pro MB to the latest iteration: 3203 released Feb 21/12. Recently my website got hacked via ftp password breach but I ran a full system AV & Malware scan and results were clean.
Windows 7 64-bit (student upgrade version), approx 8 months old.

[code] I bought this computer at Microcenter, they manufacture them and sell them under the brand PowerSpec. Mine is the B633 Since I bought it, it had had multiple errors, as shown in the attached .zip. I want to know what I need to do to fix these errors.I have ran memtest and let it do 10 passes with 0 errors. I am running driver verifier right now and have had 2 BSOD that I have never seen before, one was Special Pool...? Most of the time it is Memory Management BSOD, however.

my computer has been receiving random BSODs throughout the day, especially when I am browsing the web. The message is usually "memory management." This computer is around 3 months old. The first 1 1/2 month, it did not experience this problem. However, from July and onwards, my computer would get BSOD; it would occur at least once a day.
According to BlueScreenView, the driver that is causing BSOD is "ntoskrnl.exe."

Hey guys, so I just built my new computer a week ago but recently I've been having lots and lots of blue screens. The most common blue screen is Memory_Management, I know because my computer just stays at the blue screen and doesn't shut off. I think thats a reason why im having driver blue screens and not being able to start my computer correctly, sometimes my computer can't find the appropriate Windows 7 files. I've right clicked manage on my computer and I don't seem to be missing any drivers. My DRAM voltage is on auto.

So I've been having random BSOD's for 10 day's now - They appear at complete random and I can't tell why, Each time they display 'Memory Management' - I can normally diagnose them and narrow it down, However I cannot seem to do so. Can an expert have a look at the dumps and see if they can work it out?

Recently I have been getting random BSOD some say Management, other say Non Default, Bad_Pool_Header, maybe some others but the BSOD is to fast for me to read exactly what it says. I been doing my research on how exactly I can even first look at this mini dumps found a program call (BlueScreenView) When look around i can see all id the dumps there but am seeing the the main culprit is a ntoskrnl.exe. Now I am guessing this Because it was shown alot. People have said to run memory checks, your ram sticks are going bad, restore your computer, but honestly I an clueless.
I would like to know
1) What are the step to find the problem
2) How to fix it
3) How to prevent it

Suddenly my computer could just black out, looks like it is turning itself off, but not completely. The fans is still running, but can't use the computer and the screen is black.And yesterday I got a BSOD also. Don't know if this Memory Management issue has something to do with my earlier blackouts, but I hope so. So that there is only 1 thing to fix ;-)Yesterday I ran Memtest86+ for 10 passes and 22 hours. And I got zero errors. See picture.

I am trying to use all the 4 GB of RAM that I have for my computer so I decided to "upgrade" to 64-bit. The only problem is that when I boot from the installation CD I get a memory management error. I know that my CPU is 64-bit capable as well as my video card. As for everything else I am not sure of. What is a way to fix this problem because I desperately need to upgrade to 64-bit.

Acer Aspire 4740G. 2 years old. Last 1-2 weeks constant BSOD as per title, and random freezing up, forcing restart. On restart, random issues pop-up e.g. "Windows explorer is not working", "Login services not working (causes me to be logged into a new profile, all settings, icons, wallpaper gone)". The system has run the Memory Diagnostics test. Extracting from the Event Viewer, the results are as follows:

i'm having issues with my Windows 7 Ultimate 64 bit PC. Every so often it will just BSOD on me. I've had a look at the errors and it mentions MEMORY_MANAGEMENT and ntoskrnl.exe, but i don't really know what i'm doing so i figured i'd get some REAL help. I've recently installed new graphic drivers, hoping that might help but it just crashed on me again.Windows was pre installed on the machine and the machine itself is only a year old.

i am having a problem with my memory getting tied up / used up and not being able to access it again until i reboot.
machine: dell xps studio 8100
os: win 7,
processor: i7 2.8
ram: 16gb (max it will take)
video: ati radeon 5700 (running 3 monitors)
versions: as far as i know i am running current versions of everything, including video drivers, flash, chrome, etc. (i've tried running chrome with both the build in version of flash and the system version -haven't seen a difference)
browser: i nearly exclusively run chrome / canary with auto-updates so am at the latest builds.what seems to cause me to use up / run out of memory is after i play videos (Internet, netflix, etc.), the memory seems to get used, but is not returned to the system, even if the browser is closed and re-opened.right now for example things are working fine; i rebooted my system a couple hours ago (but have not played any videos). i have adobe lightroom running, picasa, chrome and canary (currently 4 web browser windows open with 52 tabs open). task manager currently shows me using 8.20gb of ram, that seems pretty reasonable to me.
normally my system will keep running properly (if a program is closed, memory is freed up) right up until i start to play any videos (Internet, netflix, etc.) then it will start using up more memory. (of course i expect it to use more memory during playback) however, even if i restart the browser, the memory does not get freed back up. for example, just prior to the reboot, with everything closed, i was using right around 8gb of ram. once i rebooted, i was using 1.something gb of ram prior to opening any programs.however, once i start playing some videos, i never seem to be able to get my ram freed back up again unless i reboot the whole system. this is not just a problem with how much memory the system shows as being available, i frequently actually run out of memory. (task manager will show me as using around 15gb and then everything starts swapping out like crazy).

I find that if I run chkdsk and watch the memory usage in task manager it jumps by about 50MB every 2 seconds or so until it either finishes or hits around 3.2GB at which point my physical memory shows 99% used (I'm running 4GB), and the system of course slows to a crawl.f you just run a quick chkdsk on your boot drive you may not notice it, but try running something longer like chkdsk /r on a flash drive or chkdsk /f on a bigger internal drive (but not your OS drive as this would require a reboot) and watch the memory usage climb. I have duplicated this on both systems I have running Windows 7. My XP machine (checking the same USB flash drive) uses a much more normal amount of memory for chkdsk (20 - 30 MB).

Memory Usage Goes Up Gradually (Memory Leak)When I starting the Windows (in the first few hours) everything is normal But after 1 day or 2 (sooner or later) the amount of available memory gradually goes down and the physical memory usage increasing. This increasing, continues until the memory usage reaches near the 88% and at that point , there isn't any memory available to operate any software . Also when memory reaches that point, I can't access any drive in the HDD; because everytime I want to open any folder, the following error appears :c: is not accessible.Insufficient system resources exist to complete the requested service At this point, I even can't shutdown or restart Windows normally; I must restart windows manually by pressing the restart button.after restart, everything goes to normal again; but this problem appears again and again ...
my system :
------------------------
OS : Windows 7 x86
Cpu : Intel P4 3.0GH
Vga : nVidia 6600

RAM : 2GB DDR-400 Transcend
(I have these memories for 2 years)
Physical Memory: 2000 mb
Paging File: 2000 mb
Virtual Memory: 6000 mb
0- using some optimizing and freeing softwares like (Memory Booster Gold - RAM Saver Pro - CleanMem)
1- Scanning my computer with antivirus and antispywares
2- Changing antivirus software
3- Updating windows with all updates available via Windows Update
4- Updating drivers of all hardwares
5- Downloading and installing the following hotfixes that are related to memory leak : The memory of the nonpaged pool may leak when you enable IPsec on a computer that is running Windows Server 2008 R2 or Windows 7 A memory leak issue occurs in the Windows Management Instrumentation service on a computer that is running Windows Server 2008 R2 or Windows 7 FIX: A memory leak may occur when you use the Microsoft ActiveX Data Objects Library in Windows Vista, in Windows 7, in Windows Server 2008, or in Windows Server 2008 R2 A memory leak occurs when an ADO Recordset object calls the UpdateBatch method A nonpaged pool memory leak occurs when you use a WFP callout driver in Windows Vista, Windows 7, Windows Server 2008, or in Windows Server 2008 R2

I just built a new computer and started with 8GB of memory. A few weeks down the line I purchased another set of the same memory because it was on such a good deal and had great reviews (newegg). It also was working well for me, so I figured maybe more could be better.
I haven't noticed any decrease/increase in system performance except Alt-Tabbing has recently got slower. Also, Windows 7 was sitting tight on 1.3gb to 2gb of memory usage prior to the extra 8 (now 16) being added. Even when gaming, it went up to like 3gb. Now that I've added the extra it's going up to 4.5gb or better. Also, is it possible to speed up my alt-tabbing? It seems to have a good 3-4 second pause in it instead of being immediate like it was.
Computer specs:
Windows 7 HP 64-bit
gSkill 16gb 1866 memory (BIOS shows it at 1866, too)
Intel i5-2500k Sandy Bridge (OC'd 4.6 with factory Overclock presets)
ASRock z68 Extreme4 mobo
