Laptop use only 4GB RAM of physical 8GB in 64bit Windows 7

In my laptop HP630 had 4GB of RAM. I have installed additional 4GB. But the Bios shows 4GB of memory instead of 8, and Windows 7 x64 - also shows the memory capacity 4 GB (3.86 available). However, the program CPU-Z displays properly connected the card in the first and second slot, and the total volume of 8192 Megabytes.
How to make Windows to use all the memory?
update: 28.04.2012
The new board was defective, the store replaced under warranty, and are now defined all 8 GB
problem solved

Hi,
your MBP has a +"NVIDIA GeForce 320M graphics processor with 256MB of DDR3 SDRAM shared with main memory"+
http://support.apple.com/kb/SP583
That's why you don't get the full 4GB but 3.74GB.

the snow leopard limitation has not been withdrawn, and the Mac OS Lion restriction will be removed? or not?

Kernel for i686 which uses all 4GB RAM?

I've got i686 (x86) version of Arch installed. How can I make it use all my 4GB RAM? It just sees 3,3GB now. I know it's possible to use more than 4GB on 32-bit with some tweaks etc (I'm using 8GB on RHEL i386 servers at work), but how do I make it so in Arch?

True Ibertus but not apparent from the post.
An added observation is that the added PAE requires ram for addressing so the full 4GB is not accessible, about 3.5GB is useable. Thusly, the added 1GB is actually only a half GB and requires the 64g highmem mod to the kernel..required for every new upgrade.

Itunes shows only 4gb free for my 8gb touch

My 4th generation ipod touch 8 gb shows only 4gb as total size in itunes. I had recently restored the os to 4.3.3, I also uninstalled all apple products as mentioned in the complete uninstallation guide but the issue still persists. I suspect its the 64 bit itunes issue. For once I could play few songs that were loaded by the service center guys(I had left the device for diagonistics, they say its all right) but after that itunes could never read my ipod. All backup sessions failed. I'm also in doubt about the hardware(ipod) itself.
I cannot buy a mac just to sync my ipod, please anyone suggest something that I can and should do. I'm really bugged up. All contents in the ipod is lost now and even the downloaded apps donot show up in itunes as I had done all possible sort of cleanup.
Dell XPS, windows 7 home premium 64 bit.

With the iPod connected to your computer. go to the Summary pane for your iPod and list the storage used for the different categories. The "other" should be less than 0.25 GB but can be very large and to reduce it you need to restore your iPod to factory defaults/new iPod.

Anyone using 8 GB RAM on 13" MBP (2010) and Windows 7 64 bit in Boot Camp?

I am wondering whether the upgrade price of $300+ is worth it and if performance will be a big boost. I am also interested in the performance of VMWare Fusion while running WIndows 7 64-bit (with 8GB RAM).
thanks!

The issue may be related to the iMac 2013 only having USB 3.0 ports and that windows 7 does not come with drivers for it. Try the following (borrowed from answer on Mac Rumors Forums http://forums.macrumors.com/showthread.php?t=1659481):
<quote>
If you run into issues with keyboard and mouse not working (due to USB 3.0 and Win 7 incompatibility), you need to run your Win 7 partition (and Win 7 installation disk/partition) in legacy mode. (I found this information at:http://twocanoes.com/winclone/support#faq123 - see "Method using Terminal"). Here you will be setting the legacy on the installation volume of win 7, not bootcamp partition (yet). After running the diskutil list find the volume with installer of Win 7, and then run the command (substituting the disk1s2 below with the information you find through diskutil on your computer:
sudo /usr/sbin/bless --device /dev/disk1s2 --setBoot --nextonly --legacy
Enter administrative password when prompted. Next, select Restart from the Apple menu. Do not hold the Option key while restarting.
You should have mouse/keyboard working. Begin the Windows 7 installation. Upon first restart right after the installer completes, boot into Mac and set the legacy mode for the BootCamp partition (but this time without the --nextonly flag), so you can use keyboard/mouse to complete the installation and thereafter until the USB 3.0 drivers are installed).

Laptop using too much RAM

I've had this problem for ages now and I want to know why.
These are the stats from my Activity Monitor:
Free: 170mb
Wired: 927mb
Active: 2.02gb
Inactive: 947mb
Used: 3.85gb
VM size: 258.16gb
Page ins: 47.91gb
Page outs: 7.4gb
Swap used: 3.95gb
Correct me if i'm wrong but doesn't this mean the system is desperate for memory and could be using up to 3.85gb + 3.95gb = almost 8gb (used + swap)?
After like a week my laptop is nonstop beach balling the ram available runs to 0mb and the system stall, more evidence pointing to the lack of RAM.
But heres the problem, when I add up the real and virtual ram of all processes I get the following totals:
Total real = 2.83 GB (system claims this to be as high as 8gb from above)
Total virtual = 7.74 GB (system claims this to be over 250gb)
I've had multiple apple engineers on it and none of them have any idea. This was an upgraded system from leopard to snow leopard. I've tried reinstalling the system and copying my home folder back over and only installing the software I need, doesn't make any difference.
Theres a gushing memory leak somewhere and I want to find it. Any suggestions?

No, what it means is that you don't understand the data. Your computer has 4 GBs of RAM installed. At the moment you used AM to provide the statistics your computer had 170 MBs of Free and 947 MBs of Inactive RAM or a total of 1,170 MBs of Available RAM. The balance of the 3.85 GBs of RAM is in use. 927 MBs is in use by the OS - Wired - and 2.02 GBs is Active meaning it is in use by the running applications you are using.
If your computer has a swap file in use of 3.95 GBs, then it means you are trying to use too many applications concurrently for the amount of RAM you have installed. This will result in severe slowdown accompanied by excessive thrashing of the hard drive. Simple solutions: 1. Run fewer applications concurrently; or, 2. Install more RAM.
The information on Virtual RAM is irrelevant and has meaning only for programmers. It has nothing to do with actual memory use by programs.
I doubt any Apple engineers have looked at this or they could have told you what I've said above. If you spoke to engineers without a clue, then I doubt they know anything about Macs and probably work for another company, not Apple. For more about memory usage in OS X see the following:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.

Portege M400 - unable to use full 4Gb RAM

I've installed two KTT667D2/2G modules on my laptop (Portege M400-103, part. no. PPM40E-012018G3) - making total 4Gb. However, both original Windows XP Tablet and Ubuntu 9.04 are unable to see all the 4Gb - they see 3.2Gb only.
The BIOS shows the amount correctly - 4096 Mb.
I've also tried to fix the issue by updating BIOS to the last version (3.80, 30/05/08), but both OS's (Windows and Ubuntu) still see 3.2Gb only.
Any ideas? Thanks.

But that's ridiculous! Why the specs tell me [maximum expandability : 4,096 MB |http://eu.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=EU&BV_UseBVCook ie=yes&PRODUCT_ID=114027] if the installed CPU doesn't support 64 bit? I see "4096 Mb", I go and buy these 4Gb and I can't use it all. So I wasted my money just because they didn't bother to state 3.2Gb instead of 4Gb (being aware of the 32 bit CPU limitation) !

Does the iPhone 4S (or any iOS devices) use only partial ram when doing intense things such as playing a really graphical intense game?

I heard that when using the iPhone 4S, the user can only access 200mb instead of the full 512 mb, is this true?

Any update will cause problems for a few users. And those users will rush here and post "the sky is falling" stories about their experience. The 99.99% of people who have no problems after an update won't bother to post here; indeed, most of them don't even know ASC exists. FWIW, I had no problems with iOS 7 on my 4S. Your problem is most likely not related to iOS 6, but you should probably update anyway.

Bridge memory leak/using too much ram

I just built a new PC tower for business use and installed PS, ID, LR, and BR CC trials. I already have all of these (CS5) on my personal laptop, all work fine. Bridge on the new tower has been using WAY too much ram/caching too much and crashing everything. I'd changed cache preferences, purged the cache several times, and within days it is back at it again. PC specs: 8 core AMD processor, 16GB ram, 2x 3TB HDD
This is being used to show photos, edit, burn and print at events. I cannot keep closing bridge every half hour to keep my computer running. Right now bridge is NOT keeping 100% previews in cache, exporting cache to folders, cache size is about 25,000. If bridge is going to crash every half hour on a machine with 16GB of ram, while CS5 ran fine on my laptop with only 4GB something is seriously wrong. At this point I don't know if I should actually subscribe to CC or just move my CS5 to this new computer.

I have tried to analize better what happens. In the dashboard I only have a calendar, a calculator, a clock and one postit (but there is nothing writen on it). If I use something in the dashboard, for example, the calculator, and I do some multiplications, after a couple of minutes the use of memory of the dashboard starts to increase. I closed any other program and in some minutes I have sen how it increased until I stopped the process when it was using more than 2GB! (you can see it in the picture). It's very strange! (Thank you very much for your help!)

Which one to buy Macbook Air 13' 4gb or Macbook Pro 8gb for Computer Science Course

I'm starting university in July and I'm considering purchasing a rMacBook Pro 13" or a MacBook Air 13" to use during my study. I just can't decide which to go for.
The problem with Macbook air is that it is available in only 4gb RAM in India(no option for 8GB yet ) so for 8gb of RAM i have no other option but to go for the much expensive rMBP which costs arnd 600$ more than the MBA here after the student discount.
I will be mostly be using it for coursework, development purpose and movies, not into gaming that much. Wont be using it for photo-editing or video editing purpose, so the doubt that 4gb of RAM would be enough for the next 3+ years. Maximum usage would be running a linux or Win VM and IDE running in it along with maybe an IDE running on the OSX too. Thats the max usage i could think of.
MBA costs arnd 1060$ and rMBP 1685$. So is the rMBP 8gb worth it for my usage as it is expensive or the MBA would be sufficient enough to last me arnd 3 years according to my usage.

Should the recent or (whenever next) future models have the same limits and inaccessible upgrade design, while highly engineered and nice to look at, as the late 2013; that will turn some to look into finding new-old-stock older models that have removable battery (not glued in) and replaceable or upgradeable RAM where they didn't solder in the chips.
http://www.macrumors.com/2013/10/25/teardowns-of-late-2013-retina-macbook-pros-r eveal-no-improvements-in-accessibility/
You may have to consider an earlier model if you can locate one, that has access to upgrade RAM chips as you see a need develop for greater capacity for specific use; and one that does not have a glued in battery. The ability to upgrade the hard disk drive or have an SSD replaced without major issue or high costs, is another factor to an end-user and one who may not be able to afford to buy anything this costly every year as needs or situations change, or as issues develop in use and demands on the unit present shortcomings for some users.
Subtle hardware change can occur in an existing model line, but we'd have no way of knowing it here, and main media or news releases would be the main source of information; short of knowing someone at a retail store or the online store when you may get a rare opportunity to pre-order a new computer, after news of its pending arrival has hit the streets. By then, the specs are already set in metal, plastic, and retail price.
If there were a source for restored or renewed products of a few years ago, at good discount, with some kind of warranty or guaranty that had a local service on the ground there, I'd suspect that'd be a consideration. In the US, there are several companies who repair and sell repaired computers, in their web site, and get some from lease returns that they can refurbish; these are independent companies such as powermax, wegenermedia, and others who advertise in a limited circle of market.
I wonder if there are any options to order from another country or region Apple Store online where they may offer more inventory; but have no insight or answers to that kind of thinking. We're user-to-user volunteers and sometimes the information is missing to any of us here, that a retail product expert would know.
Wish I could be of more help, but I don't see how at this point.
Good luck & happy computing!

10gR2, Win2003, 32Bit, Oracle see only 2GByte RAM from 4GByte in Machine

Hello,
i have done a default installation on Win 2003 with 10gR2 32Bit
on a Maschine with 4GByte RAM.
i try to grow up the SGA configuration over 2GByte (e.g. 2,5GByte for SGA_MAX_SIZE) but Oracle don't start, not enougth Memory.
Configuration below 2GByte works.
In the System-Information of Windows, it says it have 4GByte RAM
In DatabaseControl a the Host-Information Oracle give the Information that the host only 2GByte RAM have installed:

Have anyone a idea?

Hi Jens,
the same here.
seems, that is the restiction of w2k3 where you could only adress 2gb memory on 32bit OS. (without any options like /PAE or /3GB)

Control Panel shows only 4GB of RAM but product specs say I should have 8GB

My HP Pavilion Elite HPE-250f desktop is supposed to have 8GB of RAM factory installed, but the control panel only shows 4GB. When I run diagnostics with the Support Assistant software it says everything is working fine but also shows only 4GB of RAM. I've had the computer for several months now and the warranty recently expired. In the past I noticed it said 4GB and thought I must have purchased a computer with only 4GB, but it always seemed odd to me. I looked up the specs online and it says the HPE-250f has 8GB, and it also says 8GB on the box it came in. I have not made any modifications to the computer, and have never opened the cabinet. I am hesitant to open the cabinet, but don't feel I should have to pay a lot of money to figure this out.

Hi,
Shut down the PC. Tap away at f10 as soon as you start the PC to enter the Bios Menu - on the first page, you should be able to see the ammount of physical ram installed.

A700: 8gb of memory installed, only 4gb are being used

The a700 that I purchased from lenovo.com was the top model (40244JU) in the a700 series and came with 8gb of memory installed. The os system screen properly shows the 8gb of memory installed. The bios screen shows only 4gb of memory installed, thus only 4gb are being used by the computer. Please tell me how to update the bios since there do not seem to be any bios updates for the a700 on lenovo.com.
Thank you.

You can leave the existing RAM in their current slots and add compatible modules in the empty slots. For best performance, add two of teh same size. Our 2010 iMac 21" shipped with 4GB RAM---two 2GB modules in two of the four slots. I added two 2GB modules to the empty slots and now have 8 GB RAM.
Be sure to order RAM from a trusted Mac-savvy RAM vendor. Some vendors thing a Mac is a hamburger. For over a decade I've bought all our Mac RAM (and we have 18 Macs in teh family!) from one vendor:

The link is to the proper RAM for your Mac.
Crucial.com is also a trusted vendor.
