Installed 3gb ram, but only 2gb usable?

I installed an additional GB of ram on my thnkpad T400, and after booting up, I right clicked computer in the start menu and went to properties. It says "3GB installed (2GB usable)". How do I make all 3 GB usuable? from what I understand 3 GB is the max on a 32 bit OS
EDIT: Now after going to system configuration>boot tab>advanced>i set the total memory to 3000MB, and now under properties on my computer it says "3GB installed (2.46 usable)

Not that it helps, but I've got some notes about this issue on my T400, and what sort of RAM I could make available. Note that I'm running Win 7 Pro 64 now, not Vista 64 as it says in the notes. You couldn't make me go back to Vista or any 32 bit OS if it was the last OS on earth

4G ram but only 2G usable

Hello,
I changed my OS from WIn8 to WIn7 Pro 32Bit. I notice today that under system it says that I have 4G of Ram but only 2G is usable!!
Is this due to my change of OS?
How do I get all of ram to work.
THanks

Operating System: Microsoft Windows 7 (32-bit)
That isn't due to change in O/S it is the version of O/S your using that determine your RAM usage. 64bit Windows will access more then 2gigs of RAM but 32bit Windows will only go far as 2 to 2.5gigs of RAM usage. If you want full 4gigs or more you will need to have Windows 7x64 to use the full 4gigs of Ram. Also your O/S listing alreadys tells that your 32bit will not use RAM above 2.5gigs.

Satellite A100-750 PSAAR, 4GB RAM installed, 3GB RAM usable

I've just upgraded the RAM of my Satellite A100-750 from 2x1GB to 2x2GB.
The BIOS recognizes 4GB of RAM
but then the BIOS output states "3GB system RAM passed".
My Windows 7 Pro 64bit OS says that there are 4GB RAM, but only 3GB are used.
How can I use all my 4GB RAM?
It shouldn't be an OS issue but maybe a BIOS one.
I've tried to update my BIOS (now System BIOS version 6.0),
but with no success.
Any suggestion?
Thank you very much in advance,
Carlo

Dear Andrej,
thank you for this link.
It seems that my BIOS doesn't support the memory remapping feature,
or at least I can't find it anywhere in the BIOS setup (any help?).
At this point my question is if Toshiba will deliver in the near future
a BIOS able to setup memory remapping for Satellite A100 series,
or if it is possible to enable this feature using the BIOS of another series.
Frankly it seems to me quite odd that Toshiba sells a laptop
certified to support 4GB of RAM and 64bit mode instruction set
but at the same time it doesn't provide a BIOS able to actually exploit 4GB of RAM.
How can I setup memory remapping on my laptop?
Thank you to everybody,
Carlo

PB 12" G4 supposed to have 512Mb RAM but only 384 ?

CPU Speed: 1.5 GHz

Ok those are the specs of my machine
It was bought June 05 and came with 10.3.
I then installed 10.4 and have updated to 10.4.4.
In October I was editing a large DVD file and my mac became really slow. I thought it was bc my HD was too full (which it was). so then I bought an ext HD and transferred heaps of data over..
But it was still really slow, the same as before.
I am pretty sure it came with 512mb ram and is supposed to. I don't remember what it said when I first bought it but I'm pretty sure it would've been 512.
I have not tampered with or opened the RAM slot.
I bought the PB from a reputable apple reseller here in Sydney so I doubt they would've done anything dodgy. I called them and they confirmed it should've had 512. They also told me if there are major probs it will take up to 4 weeks to fix.
Since I can't live without my computer for 4 weeks (!!) I thought I could figure it out by myself.
Any ideas?
thanks.

Hi Livia,
I had the same problem with my PowerBook. Suddenly 128MB of RAM disappeared and the computer became slow. I was sure I had 512MB of RAM.
You should check in the System Profiler under Diagnostics if there is an error.
In my case, System Profiler reported an error with the user-replaceable RAM. I installed another RAM (1gb stick) the computer only recognized half the RAM from the chip and System Profiler was still reporting an error.
Now I must to take the powerbook to the technical service because the problem is in the logic board, not with the RAM.

Computer recognizes 8GB of ram, but only uses 30% of it?

Windows 7 Ultimate x64
Intel Q9550
ATI radeon 5770
P5QPL-AM ASUS motherboard
OCZ 8GB (2x 4GB) Platinum series RAM. pc2-6400 DDR2, 240 pin, non ecc, unbuffered
I have installed 8GB ram into my computer. Both my BIOS and system properties state I can use all 8GB of it. However- even when I put my computer under huge strain, I've never seen it go higher that 30-31%. It idles on about %20, so that means when I put strain on it, it only ever goes up by %10! I have not set a limit in msconfig either.
It's frustrating me why my computer isn't using all my ram. If anybody has any suggestions, let me know!
Here's an example: I open photoshop with a huge canvas (A0), and went crazy with a large brush. I've allowed PS to use %75 of my memory. PS lags heavily, yet my ram will not budge higher than 30-31%. Here is a screenshot of it. The ram is the steady blue line.
I would be extremely thankful if anybody could share any thoughts/information. Thanks

Okay, now that we've established that Photoshop is using all the RAM you've given it (which can be a lot higher on an 8 GB Windows 7 system, by the way; as much as 90%+), let's discuss the root problem you're having:
function(){return A.apply(null,[this].concat($A(arguments)))}

You've been vaguely referring to a "lag" problem...
Reading between the lines, I believe what you're saying is that if you paint on a large canvas with a large brush, you're experiencing some delays and non-interactive activity. But no one here is a mind reader, nor are we sitting with you seeing what you're seeing.
Please take the time to specifically answer each of these questions:
Exactly what version of Photoshop are you running?
How many pixels in your "A0", and what is the bit depth?
What size brush (in pixels), and how hard (in %)?
What is the brush Spacing?
Is it one of the fancy new brushes?
Are you painting with a tablet or mouse?
How far behind does Photoshop get (a fraction of a second? seconds?)?
Do you see the same performance issue with OpenGL enabled or disabled in Edit - Preferences - Performance.
Have you updated your video driver to ATI's latest 11.2 release from the AMD web site?
A little more detail would help us help you.
FYI, I just created an A0 sized RGB image at 150 ppi (7020 x 4965 pixels), 8 bit depth, and painted perfectly interactively on it with a 500 pixel round brush with 1% hardness and 25% Spacing. However, there is a visible lag of up to about 1/2 second if I increase the brush size to 2500 pixels. This is on a VERY powerful workstation with ATI 5670 card.

I want to install an app but only for one user on my imac with Lion

I have 2 users on my mac. I would like to install some apps (iwork) but only for one user and not the other user. How can I do this?

Setup of iWork in your wife's account should only occur the once.
Updates can be performed through your account and are usually performed via Software Update.
Messages should not be popping up in your wife's account if all the iWork updates have been performed.
Go to Software Update and download and install all the iWork updates.
Unless you keep OSX up-to-date, messages will continue to come up when your wife logs into her account.

I have paid for Creative Cloud membership Photographers Plan but only 2gb storage is showing in my apps

Why is only 2gb Storage showing for my Creative Cloud account when I have paid for the Photography plan and should be entitled to 20gb?

The new Creative Cloud Photograph plan and Photoshop Photography Program are two different plans with different entitlements. The Photoshop Photography Program was a limited time offer and the Creative Cloud Photography plan is a permanent offering.
Why are the offerings in Creative Cloud Photography plan different from the Photoshop Photography Program? For example, the new plan has 2 GB of storage when PPP offered 20 GB. Also, the original PPP offering provided users with a Behance pro membership, which CCP does not.
Are you sure you do have the old program? Can you check on your order...

Installed 4GB ram, but comp only reading 3GB?

I just upgraded my 2.4ghz MBP from 2 to 4GB ram (Kingston DDR2-667 2x2GB cards). The computer reads all 4GB (in the system profiler), but when I open a program like AFTER EFFECTS, it's only using 3GB.
Any ideas why or how to fix the problem? Of course I got the extra ram specifically for programs like AFTER EFFECTS and FINAL CUT, so it'd be nice to know that i'm getting my money's worth!
thanks!

The computer reads all 4GB (in the system profiler)
So you DO have 4 GB RAM installed OK.
when I open a program like AFTER EFFECTS, it's only using 3GB.
Not all your RAM is available for an application to use; your video chip, for example, uses your system RAM.

Kernel Panic only after I install 16GiB RAM but it passed memtest and AHT

Kernel Panics occur after I installed the 16GiB RAM(Corsair Vengeance Laptop Memory Kit 16 GB (2x8 GB) DDR3 1600MHz CL10 PC3 12800 (CMSX16GX3M2A1600C10) in my MacBook Pro 17" 2011 early. It might appear in login window, or after using Safari for 2 or 3 hours. If I did't use the MBP overnight and just let it run, there would be strong possibility that kernel panic didn't occur. But on the next day when I went up and start using the computer, the kernel panic occur in half an hour.
I run the memtest for 12+ hours and Apple Hardware Test for 19+ hours, but no error was found. I tried OS X Lion 10.7.4 and OS X Mountain Lion 10.8 GM, and even a clean install of 10.7.4, but it still occur.
However, when I install one of the 16GiB a.k.a 8GiB, kernel panic never occur. I even tried one 8GiB with another my old 4GiB ram, and kernel panic didn't occur either.
I've tried to fix the problems for 2 weeks, and I did everything I can. So, can anyone tell me which part might be bad, Mac or RAM? Should I goto Genius Bar or ask Corsair for RMA?

My 8GiB RAM is also two 4GiB DDR3 1600MHz (SAMSUNG) and it was running very well.

If you have read my original reply to you post, I did mention that someimes it will work and sometimes it won't. Your Samsung might be rated at 1600MHz but the CL could be higher than your Corsair which is why it worked.
The memory Type you read in the link you provided is motherboard/logicboard depended. Your Logic board is rated at 1333MHz. So going 1600MHz will not benefit you since you're locked at 1333MHz.
good luck

I have 16gb of RAM, but only 10gb are usable?

Hello everyone,
     I have a Mid 2012 15" Macbook Pro running Yosemite. When I first got it, I upgraded to 16gb of 1600 MHz DDR3 RAM because I would be needing it for a lot of the programs I run. I have the 2.3 GHz i7 processor. Stock 500gb hard drive. No matter what I do it says that I have at max 10 gb available at a time. Here is what it says as of 5 minutes ago:
App Memory: 3.38 gb
File Cache: 1.8 gb
Wired:1.42 gb
Compressed: 10.23 mb
Used: 6.63 gb
Total: 16.00 gb
One thing That I knew was taking some was VMware fusion, for which I dedicated 2 gb to the virtual machine, but I recently deleted it and I didn't see any difference. I also have bootcamp installed, but that shouldn't make much of a difference. Any help would be greatly appreciated!

The output from this terminal command will tell you how much memory is recognized by your system, copy and paste the entirety including the comma apostrophe at the end :
system_profiler SPHardwareDataType SPMemoryDataType | perl -ne '
     $Memory       = $1 if /Memory:\s+(\d+\s+\S+)/;
     $Phase2       = 1 if /Memory:\s*$/;
     $MemSpeed     = $1 if $Phase2 && /Speed:\s+(\d+\s+\S+)/;
     $Type         = $1 if $Phase2 && /Type:\s+(.*)/;
     END { printf("%s\n%s x %s %s\n%s %s %s\n",
                  $SerialNumber,
                  $Processors, $Speed, $Name,
                  $Memory, $MemSpeed, $Type);
then hit the return key for the output.

Installed additional RAM but computer performance now worse

Can anybody please help? I have a T61 that came with 2Gb RAM (1GB + 1GB) and I recently purchased another 2GB chip. The problem is that after installation I had a total RAM of 3GB (1GB + 2GB), the Windows Experience Index score actually decreased! It went from 3.5 to 3.1!!
Also, under the category Memory (RAM), the score remained unchanged at 4.8!! Should this have at least increased? Also, I am not noticing any improvements in performance.
Is there something that I haven't done or is there anything I should do after the installation? And yes, I did refresh/update from index score.
Please don't tell me I need to buy a new notebook!!!
Thanks

Part of the problem is that with two differents sized DIMMs you lose the Dual Channel mode feature of the RAM, so the effective throughput of the RAM would be lowered compared to the two 1GB modules that operated in dual-channel.
If possible I would suggest 2 x 2G modules for a total of 4GB or if you can afford it 2 x 4G modules for a total of 8GB this will keep the dual channel mode active and the RAM performance optimal.

IMAC will work with 3GB RAM but won't boot with $GB RAM

I have a 20inch iMAC and it came with 1 GB RAM. I received 4 GB of RAM and did the upgrade. But I found that unless I had the original 1 GB RAM in either slot, the computer would turn on the fan, but never the screen and it would never boot. If I put the original 1 GB RAM in one slot and one of the new 2 GB RAM in another slot, it would come up and recognize 3 GB of RAM. I tried out both my 2 GB RAM and they both worked (to rule out bad RAM). But once I had both 2 GB RAM in the computer I run into trouble. This computer supports 4 GB of RAM according to the book and the new RAM says it is the right kind (Kingston 4 GB kit PC2-6400 for 800/667/533 MHz. I need the 667, so I should be good to go. Can you replace the original 1 GB or does that original RAM have something to allow the computer to boot? I have the latest MAC OS X updates....

Okay I did get around this and got my iMAC working. It cost me an extra $92 dollars, but it was still cheaper than buying the 4 GB from the APPLE store.
I exchanged my 800 MHZ backward compatible to 667 MHZ Kingston 4 GB kit for a PNY 4 GB kit that is meant for 667 MHZ and not just backward compatible.

I installed this and my computer came right up and says it has 4 GB of memory when I do the Apple->About this computer. It seems to work fine now.

16 Gig of RAM but only 3.2 gig showing as available in CS5

Hi,
This is my first post so I hope it is in the right place.
I have just received my new machine. It should be quite a monster. It is a top of the line i7 2600nCPU @ 3.4 GHz running Windows 7 64 bit with 16 gig of RAM and 3 drives. Drive 1 for windows and programmes; Drive 2 for data and Drive 3 (a crucial SSD) for the photoshop scratch disk. So it can access Open GL it has a Nvidia GeForce 570/PCI/SSE2 graphics card. It is a fresh install. There are no other programmes running.
After the instal the first thing I did was go to edit -> preferences->performance only to find that I only had only 3,255 MB of ram available. I would have thought that is way way low. I was expecting somthing more like 15,000 MB. Does this sound right and if not what is going on here?
Also, I plan to be working with HDR photography with up to 9 full res shots (captured Raw) with lots of adjustment layers. I have set cache levels to 4 and tile size to 128K. Does this sound about right?
Thanks for your help.

Hi Noel,
Thanks for that. Reinstalled and chose the right options this time. Now I have 14.6 gig of available RAM - much more like it. I have set ram to 90% (13200).. or do you suggest I stay within thier reccomended range of 8066-10560. Bear in mind that I have s fully dedicated high spec 128 gig SSD drrive sitting there as the nominated scratch disk.
Again thanks for your help.

Logic has an appetite for RAM - but only this week

Greetings.
I'm using the Mac Pro at work, so ignore my signature specifications.
This week Logic has completely swallowed my RAM, both on session with lots of tracks and plug-ins, and also on the light sessions where there would never usually be a problem.
A colleague installed the Sonic Birth plug-in last Friday. Could this have contributed to some weirdness?
Even without a session open, just the application running on its own, it's eating up 1.06 GB of real memory (according to Activity Monitor). This seems a trifle odd. I'm not running anything else out of the ordinary.
The Mac's specs;
2x 2.8 GHz Quad Core Intel Xeon
2 GB RAM
OSX 10.5.8
Logic 8
I am aware that 2 GB is not a lot of memory for a Mac Pro, however it's been running fine for the past 10 months so I don't believe that is the issue. If anyone can offer a suggestion, I'd be most grateful.

On my system both Logic 8 & 9 use less than 200MB real memory, even with my default project open, with no project open it's less. You're sure there's not something open in the background? Logic-8 does use about 1GB virtual memory, Logic-9 uses about 1.6GB virtual.
If you think the problem is Plugin related you can always move 3rd party plugins out of your components folder for testing.

I have installed Lightroom 5, but only have a licence number. Where do I put this number in order to register my softward.

The Lightroom was purchased through an organisation that is why I have a licence number. I have e-mailed the organisation, but of course they haven't got back to me yet.
I can open my software as it is asking me for a serial number which I don't seem to have as it wouldn't accept the codes on the box.
Help!!!

Hi Heather,
The license key or the serial number is one and the same thing. It is a 24 digit number which is required to activate your software.
In order to register your product, please visit the link below.
