• Satellite A200 PSAFCA-01H00J upgraded to 4 GB of RAM but can see only 3 GB

  Hello

  * UPGRADE RAM PROBLEMS *.

  I just upgraded my laptop from 2 GB to 4 GB of RAM, * but cannot access the 3 GB *.
  I checked all the documents, and he indicates that the laptop should be expandable to 4 GB of RAM.

  Oddly enough, the site of [mytoshiba.com.au | http://mytoshiba.com.au] does not list my exact model under "abandoned" (as if it never existed!). Although there are a number of similar models according to [http://www.mytoshiba.com.au/web/resource/pdf/discontinued-models/notebooks/satellite/satellite_a200_psafca-01k00j.pdf]

  _OTHER WINDOWS7 64 BIT PROBLEMS_

  I also added a larger HARD drive (the original HARD drive wasn't @ ~ 19 months-) as well as a fresh install of Win7 Ultimate (64-bit).

  I have the Toshiba site and updated 64-bit drivers as much as possible, including the BIOS to Mw10M520.ROM using winphlash64 downloaded on the net, the included winphlash (32 bit) of toshiba did not work as I have already installed Win7 (64).

  Incidentally, I always have problems with "Toshiba Password Utility monitoring" and the software "Driver Bluetooth software" provided by Toshiba to [http://www.mytoshiba.com.au/support/notebooks/satellite/a200/psafca-01h00j/download] - in the absence of "* Win7 64 * ' drivers I used the ' * Vista 64 *" drivers. Is this a problem?

  Hello

  I have 2x512mb ram installed in my Sat L20 but system says I only have 894 MB of ram, this means that there is some kind of problem? Thanks for your help.

  If the video card uses system RAM to increase the VRAM, then it is normal.

  Run dxdiag and look in the graphics section.

• Re: Satellite A200-1IZ - can I install RAM 800 MHz?

  I have a Satellite A200-1IZ and I want to change my orginal RAM memory 2 x 1 GB 667 MHz DDR2 2x2gb 800 MHz DDR2. It will work properly with 800 MHz?
  Here's something on the processor and RAM:

  Intel Centrino Duo processor with Intel Core 2 Duo T7250 processor technology, card WLAN Intel Wireless WiFi Link 4965AGN and Intel PM965 Express chipset
  Clock speed: 2.0 GHz
  FSB: 800 MHz
  level 2: 2 MB cache
  Standard system memory: 2 048 (1 024 + 1 024) MB
  maximum extension: 4 096 MB
  technology: DDR2 RAM (667 MHz)

  Hello!

  Theoretically, you can use the 800 MHz modules because they are compatible downgrade. This means that the RAM is also able to run at 667 MHz. as much as I know that the chipset supports only up to 667 MHz speed and you won't see a performance gain and you can also buy some RAM to 667 MHz.

  In any case, I have good experience with RAM Kingston. I use the modules of this factory always for the upgrade of my notebooks.
  Maybe this information is useful for you

  Good bye

• Re: Can Satellite A200-14 - I switch the RAM to 4 GB?

  1. my laptop "Satellite A200-14" series has 2.048 MB RAM. How much does it cost to improve to 4,096 MB RAM?
  2. can you change the RAM yourself?

  Thank you
  Johannes

  Hello!

  I put t know how much it costs to upgrade to 4 GB of RAM. This according to the modules that you can buy and where buy you it.
  Upgrade the RAM, you need modules with DDR2 (667 MHZ) specification.

  And change the RAM is quite easy. Consult your user manual, you can find instructions and pictures how to do this. ;)

• Satellite A200-1HV: Wi - Fi connect WinXP manager does not see the WLAN

  Hello from the Russia, I'm really sorry for my English.

  1st. A200-1HV, bought with vista home premium. But I have too many problems to work on vista, and I write the new version of the BIOS (download from the Toshiba web site) to my laptop. (new version of BIOS = Bios for Win XP).

  After that, I install WinXP SP2 32 Bit. All good, but: after crash, Manager of Win XP WiFi standard do not work.
  But Intel PROSet / Wireless works, but for me, this tool are not good.

  I try to fix this myself, I manually remove the driver of wi - fi card, I manually give IP to my Wi - Fi, but unresolved problem = (Wi - Fi Manager standart WinXP can't see my home network wi - fi, * he don't see *!)

  But intel Proset wireles see and correctly connected to them.
  What should I do? I don't forget to set the switch Board-top of the laptop. I turned off the sound, but no result.

  Regards JIABP.

• Satellite A500 - 1 GR - upgrade memory RAM but 3 GB of usable system memory

  I have upgraded my laptop to 8 GB (2 * 4 GB) ram. A 64 bit version of Windows 7 shows that I have 8 GB of memory, but there are only 3 GB of usable system memory. How do I use the 8GB. My Bios version is 2.00. In the Bios, I have not found the option 'enable the memory remapping feature '.

  This option doesn't exist in the BIOS and everything is controlled automatically. The BIOS update will not change.
  As much as I know about laptops Toshiba you cannot force for laptop to use a set amount of RAM.

• Satellite A100 - 847 PSAA9E - 4 GB of ram, but it reads only 3 GB Win 64 bit

  I have the laptop A100-847-PSAA9E-0R101QAR and I have 4 GB of ram installed on it.
  Yesterday, I installed Win7 64-bit system but when I check the properties of the computer, I see only:

  Installed memory (Ram): 4 GB (3.00 GB usable)
  System type: 64-bit Operating System

  What should I do to use my full 4 GB of ram?

  Hello

  To be abele to use 4 GB of RAM, three components of the laptop should support the 4 GB.

  -OS Win
  -Chipset
  -BIOS

  If one of these parts would not support 4 GB of RAM then you will not be able to get full access 4 GB.

  You use Win 64 bit that s ok so now only the chipset or BIOS can cause this problem
  Check the chipset and the Intel page research if the chipset is 4 GB of RAM capable.
  If the chipset would be 4 GB RAM capable then the question is releated to the BIOS.

• Satellite L450-ez1541 - 4 GB of ram but 2.84 usable

  Hello...

  I just bought 2 GB of DDR2 ram to my laptop Toshiba L450-ez1541 and the system say that the maximum usable ram is 2.84 and I am using windows 7 32-bit

  y at - it all? explanation of what I see and how to increase it to 4 GB?

  Thank you

  > maximum usable ram is 2.84 and I am using windows 7 32 bit
  The 32 bit OS is limited to 3.2 GB RAM. It s no matter what Windows system is 32 bit all operating systems recognize only 3.2 GB. Therefore, you must switch to the 64-bit system if you want to use more than 3.2 GB of RAM.

  In addition, a portion of main memory is shared by the graphics card and so 2.84 GB can be used by the system.

  Hope I could clarify one point ;)

• Satellite A200 starts with the message "missing operating system".

  IM wondering if anyone can help... I have a Toshiba Satellite A200, who, at the start, just comes up with a black screen and the "system of missing operating" in the upper left corner.

  I looked for solutions on the net. Nothing is really done. I tried to start in safe mode using the F8 function key, but it did not work. I tried to boot from a vista recovery disk. That did not work. I tried to reinstall vista and it came just with the error 0 x 80070002. Im stuck and don't know how started it in safe mode so that I can transfer data and then reinstall vista (reimage) on this subject.

  Can you make suggestions?

  Hello

  Have you tried to get into the Bios and check if a hard drive is recognized? If not, the hard drive no longer works. If so, try to make another copy of Windows disk.

  Make sure you wireless switch on the side of the unit is on. Click Start-online panel-online network and sharing Center => manage networks wireless (on the left) click the little more beside the word 'Add' => select 'connect to a network that is in range of this computer' => you will see a list of networks that are in range so, select the one you want and enter the encryption key if it is a secure network

• HP 1000-1312tu had installed 6 GB of ram, but it shows only 929 usable

  my laptop running windows 7 ultimate x 32 .intel (r) Pentium (r) @2. 40 GHz I have 6 GB of ram installed and usable only 929. I already tried many things and I can't do bugs... Please help me

  Hi @minxfiles ,

  Welcome to the HP Forums!

  This is a good place to find answers and advice!

  You have the best experience in the HP forum, I would like to draw your attention to the Guide of the HP Forums Learn how Post and more

  I understand that you have 6 GB of ram and it is only readable 929 reading.

  Just to be sure you're correct DDR3 ram installation?

  Installing the chips of RAM, they must be of the type suitable and properly matched.  You can have 2 @2 for 4 GB of ram or 2@4 GB to 8 GB of ram. To have 6 GB of ram, you would need 1@6 GB to 6 GB of ram.

  If you have added a 4 GB of ram with the original 2 is it came with, it is very likely what is causing the problem.

  Good luck!

• Upgraded Satellite Pro A200 - 4 GB of Ram, but I have only 3 GB

  I have a satellite Pro A200 and I uppgraded from 2 to 4 GB of Ram.
  It was not a problem as long as I have didn't ' tt start Windows Vista.

  In the back when the memory is counting upp there are 4 GB (40XX something) but when I loggen into victory. There is only 3 GB left.

  Whence my A200 Sat stuck the other 1 GB?
  I have now that the graphics card takes upp to 250 MB, but there are still some 750 GB is not there?

  Is there anyone who can help me and solve this problem, I'm just 100% satisfied with my A200 but it buggs me that is missing 750MO I SEAP for.

  Hey Buddy

  For several years he s already known that the Windows 32 bit doesn t recognize all of the 4 GB due to the limitation of the 32 bit OS.
  I think you should visit the Microsoft good, old for details ;)

• Satellite L50D-C-18J - two modules of RAM but single track only

  Hi all

  A few days ago I got the Toshiba Satellite L50D-C-18J with A10 - 8700P AMD processor.

  Factory 1 with 8 GB (DDR3L 1600 MHz) memory module are installed. According to various tools (AIDA64, HWInfo64, CPU - Z), the memory will operate at 668 MHz, that is to say 1333 MHz mode.

  The free memory slot I have with another 8 GB DDR3L held at 1600 MHz (with the same memory timings, but other manufacturers). The Bank will continue to operate only in single channel mode and not in dual channel mode. The A10 CPU should support.

  I have installed the latest version of the BIOS.

  We have an idea of how I have the dual-channel mode and can set the frequency of the memory? In the BIOS, there is unfortunately almost no parameter or someone has the same laptop model and with it dual-channel mode is running?

  Thanks and greetings

  Mario

  Hello. Another manufacturer is not a problem.
  You should check the following:
  (1) make sure that the two RAM modules operating at 1.35v. Search the Internet, what should be the supply voltage of the RAM you have installed. If this does not work at 1.35v then that's the problem.
  (2) whether these RAM modules supports ECC. If one of your RAM supports ECC and the other is not, that's the problem.
