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.

Satellite A100-906 - BIOS see 4GB RAM but OS only 3GB

The [manual|http://eu.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=EU&PRODUCT_ID=1 20569&DISC_MODEL=1] says that the laptop supports 4 gigabytes of memory and the BIOS displays them, but the operating system (x86_64) sees only 3 gigabytes.
~$ cat /proc/meminfo
MemTotal: 3093996 kB
~$ uname -a

What me do?
Thanks.

No, I do not use Windows.
I tested with different versions of the Linux operating system and Unix (opensolaris, openindiana).

Yes, even the technical documentation on the chipset is confirmed, but nevertheless, 1 gigabyte had disappeared. : (

Satellite L300-145 - BSOD appears if I install 4GB RAM

Hi all
i have this Satellite L300-145 PSLB0E-03601LPT and I want to install 4GB RAM but when I install 4GB on SO boot BSOD appears.
I try to change with other brand memorys with equal modules, I try to install Windows 7 64bit, Linux 9.10 64bit and it the same things. I try also to update BIOS but it the same.
I think it is Remap memory feature on bios but doesnt have that option.
So what i need to do?
My laptop have now 3GB
CPU: T2390 1,86Ghz 533Mhz
CHIPSET: GM965
RAM:2GB DDR2 533Mhz
HDD:Hitachi 200GB
After upgrade
CPU: T8300 2.4Ghz 800Mhz
RAM: 2GB DDR2 667Mhz
HDD: Seagate 7200.4 250GB
I realy need 4GB

Im sorry i confuse with other chipset.
But if i can get 800Mhz and 3GB 667Mhz Dualchannel its very good.
But i dont understand the BSOD.
This is my test:
1) I install 3 difrent 2GB modules and i get the same BSOD on boot OS, but i can enter on bios and i can see on memory info. 4096MB.
2) I try to instal 3GB and laptop boot well but i find one problem if i put Bank0:1GB and Bank1:2GB laptop boot ok but if i swap i get the same error BSOD.
I think one slot cannot address 2048MB of size.
If i install only 2GB on that slot i get the same BSOD.
I have 3 tips of ram
2GB 533Mhz 667Mhz and 800Mhz with difrent brands and chips.
why i this BSOD only appears on boot OS and i can enter on bios without a problem?
Sry for my poor english
Best regards

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM... I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM? Is there any way to get more VRAM to play games on steam?

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
Dylan

The only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.
Ciao.

I installed LR 4.2 so I could tether Canon 1 DX, but camera only reads BUSY. Any suggestions?

Hi,
Make sure you have installed the release version of Lightroom 4.2 @ www.adobe.com rather the Release Candidate; which is not final GM version.
You can download LR 4.2 release from following link.
Windows:

Mac:

Same problem has been reported on http://feedback.photoshop.com/photoshop_family/topics/canon_eos_1dx_will_not_tether
and installing the release version of LR has resolved the issue.
Please let me in case still facing same issue.

I have 4Gb RAM, but it recognise only 3.46

Hello! I have bought a Lenovo G50-45 laptop which consits of 4 gb RAM. I installed Windows 8.1 (type 64 bit) , but it still writes that i can use 3.46 gb from 4 gb. What can be the problem? Any solution? Thanks to your help!

Thank you so much! So I still have 4gb, just it shows me less. But for example if I want to install a game (which needs 4gb Ram) will it start or not? I mean my 3,46 instead of 4 won't influence the game? Thanks!

Can I install 4GB RAM in my Satellite A100-033?

I have a Satellite A100-033 (PSAANE-03J02GEN). The manual says that it will support only 2GB RAM maximum. Does anyone know if it will in fact support 4GB? I have installed 2x1GB instead of the supplied 2x512MB, and am tempted to install 2x1GB? Will this work, or is there some restriction in the motherboard or BIOS which means that the larger RAM won't be recognised? Can anyone help?

Thanks. I agree that the fact that my laptop's specification says "2GB maximum RAM" is a bad sign, but I have found in the past that specifications aren't always completely accurate, which is why I enquired.
My processor is a 1.6GHz Intel T2060. A check on my laptop (by the program "Belarc Advisor") says that my motherboard is an Intel Capell Valley (NAPA) CRB, and that my BIOS is a Phoenix 6.00 07/12/2007. Is there any way whereby I can find out if this combination will in fact recognise 4GB of RAM?
I know that 4GB only yields a little over 3GB usable RAM, but I would still like to increase the amount of RAM which I have, if this is possible, but obviously I don't want to spend money on 2BG chips which then don't work in my laptop.
Any suggestions gratefully received!

770T-C45 Maiboard - blue screen error when installing 4GB RAM

Greetings,
I bought the MSI 770T-C45 mainboard to replace my older mainboard (ASUS M2N32 SLI Vista Premium). The problem is that the MSI board resulting blue screen when i install 4GB of RAM. First i thought maybe because of the BIOS. The same problem occur after i flashed the BIOS with the latest version using MSI Live Update. Here are my current PC information:
AMD Athlon II X2 X245 - 2900MHz (overclock to 3487MHz)
MSI 770T-C45
1Gb OCZ Gold PC6400 (3 sticks)
PowerColor ATI HD4870 1Gb Stalker Edition
Hitachi SATA2 250Gb
Vista x86 SP2
CoolerMaster extreme power 550Watts
I wanted to use Vista x64, but since my board can only support 3GB of RAM, so i use vista x86 instead.
Could anyone give me some suggestions? It is a waste to not fully use all the DIMM slots.

unfortunately the problem occur before the OC.. i just did the OC yesterday..

Can I install 4GB RAM in an Satellite A200-1VP?

Bought an A200-1VP a couple of weeks ago and think it could benefit from a bit more RAM. I am aware that under vista 32bit I won??t be able to access all 4GB but whatever I could gain would be a bonus (3.5Gb?) can 4GB be installed in my notebook without any problems?
And just out of curiosity is the processor upgradable? Highly doubt id end up doing it but would be nice to know?
Hope anyone can help
Thanks
kharm

Hi
You can install 4Gb on that machine it may only recognise around 3.5gb due to system resource requirements,
It takes 2 x 2gb 667MHZ SODIMMS

Problems with Installing 4GB RAM on mid 2007 iMac

I ordered 2 X 2GB sticks of PC2-5300 DDR2 SODIMM RAM for my Boss's mid 2007 iMac from Crucial.com. Well they arrived a few days later and today I have been trying to install them for a few hours now without any luck. I have installed new RAM about 5-6 times without any problems before on different MacBooks and iMacs. After this install I plugged back into the wall and hit the power button, the iMac made a little noise (internal noise) then nothing, just a blank screen. I thought maybe the RAM was bad so I inserted 2 other chips (we ordered 4 X 2GB to upgrade 2 iMacs) and still no luck. After making sure the iMac would boot with the old RAM (which it did), I tried installing 1 X 1GB with 1 X 2GB and it booted up perfectly. I did this with all four 2 GB RAM chips to make sure they all worked and they did. Each time I successfully booted, I went to the system profiler to make sure it recognized 3GB of RAM and it did. So my question is why is this mid 2007 Aluminum iMac not working with 4GB of RAM, but it works perfectly with 3GB? Thanks in advance, sorry for the long question.

+It seems to me that it is not just a problem with the RAM but with the imacs themselves.+
How does this make any sense when one considers that Apple successfully specified, produced, sold and delivered all three iMac (mid 2007) models with an optional 4GB of RAM pre-installed?
In addition, Apple has, without issue, sold large quantities of that same RAM online and over-the-counter for customer upgrades. Much of all that 2GB, and the latest 4GB RAM, as usual, has been manufactured by Micron, the publicly owned U.S. manufacturing company parent of the Crucial direct sales division. The same type of RAM was also being provided to Apple by other manufacturers.
I received my two orders of upgrade RAM from Micron/Crucial even before I had purchased my 24-inch iMac, and it's worked great ever since I installed it. I also installed the second half of that order into my current MacBook, purchased a month after the iMac, and it's also been working great ever since. These are certainly superior Apple products.
Obviously there has been a change in RAM manufacturing design at Micron, probably due to their change-over to the costly, challenging high-tech 50nm and 40nm manufacturing technologies, and it is nothing more than Micron's problem.

My test instrument is outputting a 5 line string but labview only read until the carriage return. how can I get it to read the whole string?

I have a labview sub-VI reading the string being outputted by a pH meter. The meter outputs a 5 line string and labview is only reading up to each lines carriage return, there-by giving me 5 separate strings is there anyway to rectify this and have the 5 line read as one string?

Yes, LabVIEW will automatically update. What happens is that the old serial functions still exist in 7.1 and above but the code (the block diagram) has been modified to use VISA functions. Older versions of LabVIEW are fully supported in this manner. The only way you can avoid the automatic update is to have the old serial functions in an llb and your top level VI refer to these. Having any VI that was part of vi.lib in an llb is a very bad idea and the way to fix things is to remove any VIs in the llb that are part of the LabVIEW distribution.
I don't remember how the old serial config worked and what the new version does with the VISA Configure Serial Port. Your program should only have a single serial config and you might just be able to directly replace that with the VISA configure Serial Port.

After installing VLC (64bit), my MBP only reads CDs and ejects DVDs. Uninstalling VLC did not fix the problem. What do I do?

I have recently installed VLC media player (64bit), played a movie file on a DVD+RW for 30 seconds, then decided to stop the movie. I poped the DVD out, and a minute later I reinserted the same DVD, it was ejected after 10 second. Now when ever I insert the DVD in my MBP it gets ejected. It reads my CDs but does not read my DVD. Uninstalling VLC did not fix it. I am not even sure at this if VLC caused the problem. What do I do?

Have you rebooted since uninstalling VLC?

Why won't my macbook pro accept both 4gb Ram, It will only use a 4gb and a 2gb?

I have a mid 2009 2.6 Ghz 15" macbook pro, and recently purchased two samsund ddr3 4gb 1600hz 204 pin RAM. I removed my two 2gb standard Ram from my macbook pro, and inserted the two 4gb Ram. When I turned the computer one it began using its 3 beep sequence as if the Ram fail, so I removed one 4gb Ram and reinserted a 2gb Ram and the computer started. It said I had total 6 gb ram. I am wonderind why It won't accept both of the 4gb Ram.

Exactly what Kappy and Stedman1 states.
The RAM you purchased is way out of specs for what you need.
Go and return or exchange them for either a set of Crucial, Corsair, Mushkin or Kingston (non value) RAM.
