Satellite L40 - 13G has 667 memory but works at 533

Satellite L40 - 13G have original built in 2 x 512 667 of memory but memory works only at 533, why is this?

I flashed the latest 2.20 bios of the Toshiba site.
I did an upgrade on this model by changing its processor,
Original image was celeron M 440 and now is core 2 duo T5600,

The chipset on this model is 945GM and it supports core2 duo processor.

Now main FSB is 667 for the cpu but memory works only at 533 dual Chanel
and it's strange because the memory is 667?

BIOS doesn't have a Setup for memory clock.

Thanks for the help!

Hello

If you have read your question, you will get a response.

Your machine comes with a Celeron M, which has a FSB of 133 Mhz. This means that the whole machine has been designed (including the BIOS!) to work with that CPU and JUST with this CPU regardless what the chipset is capable of. This means that no matter what CPU and memory you´ve installed in your machine, the FSB will collaborate in the FSB 133 Mhz (533 Mhz), but your Coreduo needs another front bus.
And because the BIOS is programmed to put the FSB 533 won´t never be able to do your mem running at 667 Mhz. Maybe if you can reprogram your bios.

Welcome them

    P.S. sorry - but my English is not very well ;-)

    In my opinion, it takes a bit. Toshiba has begun to support of Windows XP Home for new preinstalled Vista laptops but obviously your Satellite L40 is still not on the list. I'm afraid you have to wait his turn.

  • Satellite L40-143 (PSL40E-04E00LGR) - memory upgrade

    I want to upgrade the memory of my laptop: Satellite L40 - 143 Modell Nr.: PSL40E-04E00LGR

    I can find my phone on the support site and the following information for the memory (which is consistent with the information I have):

    Standard: 1,024 (512 + 512) MB
    Max Erweiterbarkeit: 2.048 MB
    Technology: DDR2 RAM (667 MHz)

    I understand I can go to a maximum of 2 GB. I have two questions:

    1. question:
    By clicking on: 'Zubehör' I get the suggestion to buy the next memory:

    1024 MB (1 GB) memory PC2 - 4300 DDR2 (533 MHz) PA3411U-2M1G
    512 MB memory PC2 - 4300 DDR2 (533 MHz) PA3412S - 2M 51

    It is however 533 MhZ DDR2 PC4300, in my manual and on the technical page details it says PC 5300 at 667 MHZ, well? What is the good memory to buy?

    2. question:
    I now have 512 + 512 MB in the notebook. Can I buy a single module 2 GB instead of the two modules of 1 GB?

    Thanks for the replies!

    Hello

    In your case, I would like to buy RAM with the specifications of the user manual. In the worst cases it runs only on 533 MHz but I tried a little with Google and it seems that the laptop is using 667 MHz modules.
    Moreover, I can recommend high-quality Kingston memory.

    Regarding your last question, you can only buy two 1 GB modules. It is the maximum capacity for each RAM module.

  • Satellite L40 - 13G - need a more powerful battery

    Hello! No, my current battery is PA3591U-1BRS. I need a battery that can give me more than 2 hours of work. Can you advice something?

    Thank you!

    Hello

    I know that the battery (Li-ion, 4 cells, high rate, 2000mAh) PA3591U-1BRS, which is compatible with the Satellite L40.

    If you need a stronger one that you take the appearance on the values of mAh. The higher mAh value means a longer battery life and better performance.

    But unfortunately, I found only the PA3591U-1BRS a compatible framework.

  • Satellite L40 - Sleed and standby does not work correctly

    I have a portable Satellite L40 and it worked correctly until now. I turn and after I have put on standby (stand-by) mode; When I want to use my system, so to get that back to normal (I press the turn power button to exit the mode "standby" button), Windows Vista 32-bit restarts - it is not back to the moment I left it before the "sleep mode".

    Therefore, restarting Windows Vista 32-bit, and the screen "Windows has been disabled incorrect" appears instead to return to the configuration of the system that let him before sleep / standby mode.

    What can I do to fix this and make "sleep" mode works correctly?

    Hello!

    In your case, I'd do a BIOS update. You can search for updates on the Toshiba site
    http://EU.computers.Toshiba-Europe.com

    You should also look into the mangment of power. Here, you configure what happened when you close the screen, press the power button and so far.

  • Satellite L40 PSL48E FN keys do not work

    I have a laptop Toshiba Satellite L40 PSL48E, and it works perfectly, except that the FN + no matter what key does not work.

    I've been option on this forum, and I found the solution, which is: download the common Module and the Hotkey Utility.
    However, this only seems to work for Windows XP and I have Vista Ultimate, so this won't work.

    Also, I discovered that FN + F11 seems to work, and I searched on that one too, but it was something like:

    «So, go to "Run" (i.e. run an application) and run msconfig.exe or simply search for msconfig.exe.»

    After the opening of this program, you will have a few tabs and a tab should be as 'start-up', it should be the filename TCrdMain.exe and a checkbox before that. Uncheck the box, and you disable this cardmanager.
    "

    Well, I went to msconfig.exe, but TCrdMain.exe was not on the list...

    Someone knows how to fix this?

    Thanks, Koen.

  • Re: What is Satellite L40-15B has supported audio CD?

    Hello.

    I use linux on my Toshiba Satellite L40-15 b and there is no sound from an audio CD.
    I spoke with the ALSA community and all the settings of the software seems to be ok. So I have here, I would like to question the material.

    On this Toshiba - cdrom is connected to the sound card?
    It plays audio CDs under Windows? He plays games that use audio cd, said Total Annihilation, under Windows? (unfortunately impossible to verify myself that Windows is long gone from my laptop)

    Would be happy to get an answer, so that I can know for sure if this is a problem with the ALSA Linux drivers or with the hardware of the laptop.

    Andrei.

    Of course, you can listen to the CD on this Satellite L40.
    You can use it as a CD player.

    But you need to start the Windows OS. Without running OS you will not be able to listen to the audio CD

    Hello

    Satellite L40 is equipped with a sound card high definition and this means that you need to install SP3 first, then the audio driver.
    SP3 contains two patches from Microsoft you need for this sound card.

    So remove the audio driver installed, install SP3 and then reinstall the audio driver.

    Isn t easier to remove that software of the parts that you don't need and to clean the registry with CCleaner to do a full clean install?

    > Since then, however, work 7 special keys (play / pause, cut...) no more. How can I solve this problem?
    The Toshiba VAP (value added package) must be installed to get the buttons working again
    Have you tried that?
