Virtual Memory And 12gb Of RAM
Dec 20, 2008
This is my first post in this forum, but I was just wondering if any of you had experience with virtual memory in Vista x64 and the page file when you have a large amount of RAM. I recently just build a machine which has 12gb of RAM. I am begginning to think that this was a waste of money, because no matter what I do, I cannot seem to get the ram useage to exceed 30 percent, or roughly 4gb of ram. I am a computer science major and completely understand how virtual memory works and what paging is; however, I was always taught that if the OS (Vista in this case) will only swap memory when the memory is full, but this has not been the case as I know that Vista is paging some of the memory onto the disk even though it has another 8gb of free memory to use.
I was just wondering what your thoughts were on disabling paging in Vista and if any of you have experience with doing so when you have a system with a large amount of memory. Also, I would love to hear anybody's explaination as to why Vista is paging the memory onto the HDD when in fact it's not neccessary in my case. Perhaps I do not understand it correctly? I am currently on a different computer, but tommorow I will disable the paging in Vista to see what kind of performance difference I experience, if any and post what I find.

I am running Vista 32bit with 4gigs of ram, AMD Phenom 9950, just put in an ATI 4870X2 with 8.11 drivers. I have two hard drives, one 250gb with the OS and FS9 and FSX on it and another 500gb with really nothing on it. I have my virtual memory set up as follows:
C: and D: drive set to system managed. Should I set the custom size and to what intial and max size?
Im leaning towards the 4870x2 card the cause of the memory leak not sure if it is a driver issue, might install the 5.8 version and see what happens. Also, plan on moving FS9 and FSX to the bigger drive.

I am trying to change the size of Virtual memory on my sisters laptop. It is running vista home and has only 1 gb of RAM. I click on where you change the virtual memory and click CUSTOM (on the C drive, which is only hard drive she has). And i set it to 2048 min and 2048 max. I Click set then ok. then ok again, and once again ok. Then it prompts me to Restart the computer, so I do. But after I restart and check to see if it worked, it still shows that the custom size wasn't added.

I noticed that my virtual memory is set to no pagefile? I've tried setting it to custom, system managed, etc. I always click the "set" button and it will show what I change it to if I set a custom size. When I reboot and go back to the settings, it is back to No Pagefile?

Running Vista Ultimate 64-bit on M6400 notebook with 16GB RAM.
With 16GB RAM does Vista really need any virtual memory?
My quad core, 16GB RAM notebook would be faster without hard drive access due to virtual memory.
Can I turm off virtual memory or set it to some very low value (possibly 0)?
My preference is to use the 16GB RAM and should that be insufficient then I decide which programs to close. I don't want Vista using 4GB, or 6GB RAM, etc., and continually writing/reading to HD which slows things down and does not make full use of the physical RAM present.

I am running Vista Business x64 on my notebook. It is a C2D 2.00GHz with 4GB RAM and a Geforce Go 7700. My question is, what would be the optimal size of the virtual memory (page file) that my system should use? I currently have min=max=4092MB. Should I lower it or raise it to be 1.5x or 2.0x my RAM? Or should I leave it as 1.0x my RAM like it is now?

I need to know if there is anyway to specifically set Vista to allow a program to see a certain Size for Virtual memory. oracle Products require Virtual Memory to be verified before they go through installation. The problem here is that Windows Vista Paging files are not seen as Virtual memory for some reason. The system I have is set with 4000 plus mb of Paging file but when the oracle check completes it shows 0 mb available. Going to a newer version of Oracle is not an option as this is a required product for a College Course. Going back to XP is not an option since no one ever wrote XP Drivers for this hardware. I've hausted all the resources from HP and Oracle and need to try this end of the problem now.

I currently have 4GB of RAM installed, of which in real terms, only 3.07GB is actually being used by my system.
I am wondering, given that my RAM is sitting at max. levels, if there are any reasons, advantages or benefits to be had in changing the Virtual Memory - Paging File Size for all Drives, from the current size of 3369MB to the recommended size of 4603MB, or more....say 4950MB??

How do you edit a virtual pc hard drive image so that you can add files onto. So that if you have say MS-DOS 7.1 running on virtual pc and want to add SIMCITY 2000 to its virtual hardrive. Then you could run SIMCITY 2000 from dos on windows vista. And once simcity 2000 is added to the virtual hardrive how do I execute SC2000.exe from dos or dos shell.

Am I correct in assuming that, for Windows ME to run in a Virtual PC 2007 window, the Windows ME virtual disk must be located inside a disk partition that is FAT32? On a test run, I tried to install WinME on a virtual disk in a folder that was in my normal Vista partition (NTFS), and it didn't get far. I tried placing the WinME virtual disk inside an FAT32 partition, and although I didn't finish the installation process, I got that far, with the WinME instalation screen having popped up and ready for installation. One other thing: Is it possible to place the WinME virtual disk inside a logical FAT32 partition? Or must it be a primary partition?

I have the following issue and hope that somebody can give me a hint about what might be going on! My system has two raid 1 arrays - one is running on XP Professional SP3 the other one is running on Vista x64 Ultimate SP1. When I start my virtual machines (either from the Virtual PC console or when double-clicking the *.vmc files) than everything is working fine on XP and the virtual machines are booting and running as expected. However, on Vista the following is happening (and I hope somebody has an idea):
1. Starting the Virtual machines from the console leads to an immediate reboot of my host machine (I can't even see any boot screen of the virtual machine - it is like clicking start in the VPC console -- > reboot of host).
Now I tried the following:.........

Memory DiagnosticsIf Vista detects a memory problem in your system such as a faulty RAM module, it will display a notification asking if you want Vista to try to diagnose the problem.Then again you may also recieve the sudden BSOD with the error MEMORY MANAGMENT at the top. You can manually run this tool anytime just typememory in the search box inside the start menu.This tool offers you two options: restarting immediately and checking for problems, or running next time you reboot your machine (the memory diagnostic tool must run at boot time).
Network DiagnosticsWindows Vista also allows you to check the connectivity of your network connection using the Network Diagnostics Framework: An infrastructure and a set of built-in and extensible components that attempts to automatically diagnose and correct network connectivity problems. The usual way to run this check is to open Network Center and click the Diagnose Internet Connection link on the left Vista will either identify ............

I had 4GB physical memoryon the PC. With Windows vista 32 bit, available memory is shown as 3.3GB. I asked and was told that only under 64 bit windows, will the available memory be 4GB. When I upgraded to windows 7, I chosed 64 bit, but the available memory shown in the system is still 3.3 GB. Why is this and is there a way to make the full 4GB available? It's possible that my video card is using RAM instead of its own RAM. If I install a video card with its own RAM, will the full 4GB be available?

I have a problem with Vista Ultimate x64 SP1, I always seem to lose all my free RAM within an hour regardless of system activity, even while idling. I have noticed an svchost.eve process runs each time I reboot which seems to bloat constantly although when I close it down it only frees up about 800MB, what's happening to the rest of my 8GB??? When I launch Task Manager it says I'm only using 10% Memory but free RAM sits at 0?!?!

When I upgraded to windows 7, I chosed 64 bit (I did clean install of course), but the available memory shown in the system is still 3.3 GB. This is show in both task manager under performance->Physical memory->total, and 'property of My Computer'->Installed memory (4GB/3.3 GB usable)........

I am fairly new to the forums, and VERY new to Vista x64. The machine is new, and I was trying out some apps and games, I was in Secondlife when I got an error messege saying I was out of memory and needed to free up memory. I shut down the app and restarted it. Runs but I watched Task manager and saw my free memory down to almost nothing after an hour or so. The cached seems very high.
I did alittle research and decided to set a second page file on my 1TB hard drive, (OS is on the other HHD's )( regulated by system for size ) I'm not really sure whats going on. Example of just task manager and this page openis attached. Again, any help would be great in getting the memory set up on here optimal.

I have 6gigs of DDR3 memory at 1600hz. Running on Vista 64bit and every now and again my memory performance just maxes out. The problem can occur around the time when I am installing something but I dont think its always this way. I have read forums where it could be the hardrives performing self diagnostics. I have all the latest patches for vista.

I'm running Vista 64 Home (SP1) Premium on a homebuilt machine w/8GB (4 X 2GB modules). Windows is reporting 8 GB of Installed Physical Memory but is reporting only 4 GB of Total Physical Memory. I first noticed this when, after installing a game, the game system specs said 3092 MB of RAM.
I have checked the BIOS and it recognizes 8 GB. Memory Remapping is Enabled. Under Memory Remapping is "PCI MMIO Allocation: 4GB to 3328 MB" (?). MSConfig Boot Options shows Max Memory is not checked and no value in the box below. I tried enabling it and using 8192 as the value, but it made no difference. DxDiag shows 8 GB installed RAM. how I can get windows to make available all 8 GB of RAM? (Motherboard is ASUS Maximus II Extreme w/Intel Q9550 processor running at Q9650 clock speed, memory running at 1127 MHz

I recently built a new computer and installed Vista Ultimate. I plan on installing XP Pro as a virtual OS. I'm new to this and was wondering how much HD space to allocate for this install. Do you allow space just for the OS or for added programs as well? Also, if I understand correctly, both OS's actually run at the same time. Does this create a problem with resources, or can you put one OS in down mode while using the other? I have a quad core Q6600 and 4 GB of RAM. Hard drive is WD 500 GB.

I just installed SP1 from technet recently, and decided to try my hand at virtualization for the first time today. Once Virtual PC 2007 is installed, my system BSoDs during every boot. The only way to gain access to windows is safe mode, or using the last known good state.
After using last known good state, VPC 2007 is installed, but won't work (as the drivers/services have been removed during install). I've uninstalled the remainder of VPC 2007 and rebooted; no problems. Tried again to installed VPC, and after reboot it once again BSoDs endlessly. So it stems the error is recreatable (at least on my machine).
