Total Memory Available 3.3GB With 4GB Physical Memory Under Windows 7 64 Bit
Nov 29, 2009
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?

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'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

Hi all, I've just upgraded from 4GB to 8GB of RAM. When I look in system information its says the following:
Installed Physical Memory (RAM) 8.00 GB
Total Physical Memory 4.00 GB
Available Physical Memory 3.16 GB
I'm basicaly wondering why its says that I have 8GB installed but only 4GB - 'Total Physical Memory'? In Task manager - Performance, it says that I have 8GB of physical memory so it is being used.

As you can see this is a 64-bit OS. I'm getting these contradictions in Vista and not Windows 7 on the same machine. A picture is worth a thousand words so ... below are 6 snips, the top 3 are Vista and the bottom 3 are Windows 7 for comparison.

This is with Vista SP1 installed. I added 2GB RAM making the total installed RAM size to be 4GB. My problem is that although BIOS recognize the RAM size to be 4GB and the Properties/System shows also 4GB, but both of the System Information/System Tools and Performance/Task Manager show 2GB. How can I check to see if 4GB is being made available for the system to utilize?

I'm trying to settle a debate with someone about how Windows (32bit)
allocates memory. In short, my opponent seems to think that ALL applications
will be swapped in and out of the SAME 2 GB of *physical* memory. I suggested
that this was nonsense and instead the OS will use whatever physical memory
it has available. Thus, in theory, if you have a 4 GB system with no swap
file, you could run three applications that take 1 GB assuming that the OS is
consuming no more than 1 GB. Can I get an engineer at Microsoft to confirm
that this is how it works and if so, can I get a link that outlines that
architecture?

I have an HP Desktop Pavilion m8150n, Intel Core 2 Quad Q6600, Windows Vista Ultimate (32), 4GB RAM, 640GB hard drive, NVIDIA GeForce 8400GS. I have upgrade Vista with sp1. I have been having some problems with my pc hesitating when I'm clicking on things in a game. I have just recently upgraded my memory from 3 to 4GB, thinking this would solve my problem. It hasn't. When I go into the Task Manager, it shows Physical Memory (MB) Total 3581, Cached 2730 and only 56 Free. Is this my problem? I have a long list of processes and services running and I'm sure I don't need all of this running at the same time. This could also be causing my problem, but not sure. I have shut down some of these processes, but I'm not sure which ones I actually need to run the computer. This problem is extremely frustrating. I have 211GB free on my hard drive and the box is checked for Index drive for faster searching. I would be happy to provide any other information.

We see lots of messages on many forums related to people wondering why their system does not show their full 4,0 GO. I have 4 GO on both my desktop and laptop. It showed 3,325 GO on the desktop before I upgraded to SP1 RC. Now it shows 4,0. Same thing happenned when I upgraded to 4 GO to my laptop. Since SP1 RC was already installed, it showed 4 GO right off he bat. I guess it only shows the total memory but still cannot use it since the physical limitations are still there. Or are they? Of course I am using Vista Business on both systems, x32 version .

ive always ran XP but i heard from a friend that XP could only read up to 4gig of ram. So not wanting the ram to go to waste ive gone out and bought Vista Home Premium 32bit because he said vista could handle the ram.
After installation ive discovered that my installed physical memory is only 4GB Originally i thought maybe all the drivers have to be installed so i did that but still no difference. Then i googled it and ended up on vista forums, from what ive read 32bit can only handle up to 4gb but the 64bit can handle...well it didnt say a figure but just said "all of your ram".
Just wanted some clarification as to what i am reading is entirely true. And whether its worth going out and buying the 64bit edition. Also if i did go buy the 64 bit edition is it easily enough to just install it over the top of my current 32 bit?

for a coupla months now but it finally got to me last night, my Vista 32bit PC is hogging my physical memory on bootup---seems like forever. my light on front is constantly on. i ran through a lot of tests last night to see whats up. i did see major spikes in my resources moniter. but i could not see or find what was useing it up. my physical memory showed 65% usage. i managed to do some windows updates and reboot which helped. i also ran chkdsk for my C hard drive.(i have 3 hard drives total). since it rebooted without me there, i assume the C hard drive may be ok.

I just want to know how to optimize vista,I run very few programs except Zone Alarm Pro and Symantec antivirus. But in the task manager, there are 80 running processes, and 50%+ physical memory,the CPU usage is usually 15%-50%. Is there any professional software to optimize vista PS, friends told me vista is crappy and xp is better, but I have no other choices cuz the OS is from the HP.

I just added 1 GB of memory to my computer bringing my memory up to 1280 according to Vista and after I restarted the computer and everything loaded I noticed that the Task Manager is showing a different amount of available memory then what the system information is showing. Task Manager was showing that I only had 15 MB of memory free I knew that something was wrong so I went to the system information in the system tools menu and it showed I had 800 MB of memory available.

My system is a Vista Ultimate 64-bit with 12 Gb installed physical memory,
however, on the system summary under system information it only shows 3.99 Gb of TOTAL Physical memory.
Why is vista not able to recognize the full 12 Gb ? I thought the 64-bit OS was supposed to recognize up to 128 Gb. Any ideas???
My motherboard is an ASUS P6T Deluxe Intel X58, CPU= Intel Core i7 Extreme 965(4x 3.2 GHz;8MB L3 Cache).

I have purchased a new computer with Intel Dual Core 1.6 GHz, 256 MB Nvidia card, 1 GB RAM, 250 GB SATA HDD. My rating index is shown as 3.0 even though I have updated it several times. Also, available physical memory is also shown just above 300 MB. Is anything needs to be updated, I am unable to understand what is going wrong here.

I have Windows Vista Home Premium 32bit and the problem I'm having is my computer is not using its full Memory, like, It came with 3gigs, and I upgraded it to 4.50 gigs and it says I still have 1.56 remaining. Now I've heard people say have I remaped it...But I dont know how. Apparently I can use my extra 1.56 thats...Not being used since I upgraded it...I thought it was automatic. I'm just looking for a answer so I can use my extra RAM.(I have looked at a hotfix and when I go to download it, it says a server error or whatever and I can't download it.)

0x00000123 stop error physical memory dump. I searched it on google and to avail a few people fixed it by over-clocking, I'm not sure if they over-clock their memory or CPU though, also I don't like over-clock, anyone wanna help me figure this out? I can give any information needed. I'm also concerned about my CPU's voltage:
it's reading 1.27 right now which seems high concidering people with the Q6600 have around 1.27 X_X. Also what settings in the BIOS goes with RAM and CPU over-clocking? like I said though XP runs fine, Vista does do this.

Recently had reason to return my PC to the store because it would not post. After weeks the store said it was a RAM failure. I had 4 GB of Ram installed. Eventually I got my PC returned and they had put 5 MB of RAM in .... The problem is my PC can only see 2 GB of physical memory. I have now got three 1 GB and one 2 GB of ram installed. My PC is preforming worse than ever. I am stating to think my PC can only see or should i say use the 2 GB bar for some reason. I have even tried to change the system config but it will only allow me to select 2048 mb.

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 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?!?!

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 am using an Acer Aspire 5290G laptop running Windows Vista Home Premium. The laptop has 2GB RAM but I have been getting Low Memory warnings after which I have had to reload Windows. At the time the only not automatic applications running are Norton Internet Security, Messenger, iTunes and iPlayer from the British Broadcasting Corporation (BBC).
I've tried increasing the virtual memory size to min 4096Mb, max 6144Mb so I'm hoping the problem will go away but it would be useful to know whether this is some kind of known fault or if it is just that Vista is so demanding! I had been running a similar or greater load quite happily under XP Pro on another laptop with only 512Mb RAM. The only intentional difference is that this laptop is running Norton Internet Security whereas the old one was running F-Secure. If the problem persists, is it worth me adding more physical RAM and/or trying a further increase in virtual memory?

I m trying to install AVG, and I was receiving installer issues. I approached other Tech sites and was told to use a program, basically now I cannot install any program, and I receive the error concerning windows installer... "The Windows Installer could not be accessed" I attempted re-install the installer on the Microsoft website, but it gave me the "Not enough memory to process this action"
I've spent countless hours troubleshooting and yeah... I'm just tired of it. Preferably I'd restore to a previous system restore point, but I get the memory error with that... so yeah, no luck with anything.
