T400 2764-CTO memory updgrade

Hello

I intend to upgrade RAM on my T400 as I am running Win 7 64 bit

Currently, I have 3 GB of Ram and I'm planinng to add 4 GB of Ram such as:

4 GB PC3-8500 DDR3-1066 SODIMM of Low-halogen (the plan is to remove 1 ram and swap with 4 GB of ram, so in total I've got about 6 or so...)

My problem is that I don't know what kind of RAM there currently that is 1066 MHz or 1333 MHz. Also, I do not know how DIMMS have my laptop?

Is there a way I can find this information for my laptop without opeining the back of the machine?

Appreciate any help.

CPU - Z will show you the kind of DIMM:
http://www.CPUID.com/softwares/CPU-z.html

The T400 will use either 1066 MHz or 1333 MHz DIMM to 1066 MHz anyway.

Here is the disassembly instructions:

Basically, it's the four screws of the Palm, and the palm rest detaches to expose the DIMM slots under the touchpad.

  • HP Pavilion p7-1400z CTO memory

    IS DDR31866MHz compatiable?

    Hello

    That's what the card mother sheet States.

    Everything is not always as it seems at first glance.

    You also get to see that in theconfigurable HP desktop options, optional modules of memory configurations are limited to DDR3 PC3-12800?

    This brings me to committed an error on the safe side and suggest only using modules of memory configurations and capabilities that HP has tested and marketed for the desktop PC.

    Armed with this information, you can make a wise decision on what to buy and minimize your financial risks and potential problems. The potential problem is that unless you use what is recommended by HP and manufacturers of memory important, your PC cannot boot into Windows.

    Be aware that the card mother Jasmine is not the amateur vareity.

    The HP InSyde BIOS, you cannot set the primary and secondary memory timings and voltages of different buses to optimize the operation of the memory module.

  • Pavilion17t-gOOO CTO: memory upgrade

    I want to add more RAM and I did on previous laptops.  Is the new ram available for this model and makes him?

    This laptop has no separate RAM compartment which is what I'm familiar with so I don't know what the process would be to install the new ram.  Take off the entire back seems daunting.  Can anyone help?

    Yes this does not change my opinion at all. You can add a 4 GB module for 8 total, but you could install 2 x 8 to 16 total.

    I'm trying to do a clean install on win7 64 on my t400 (2764-CTO) ent

    I burned my drive to a .iso directly from my microsoft partner portal.  When I boot the disk, it starts and starts to copy the files.  After that, I get a small windows with a black background splash screen.  After that, all I get is a mouse with a black background.  I can move the mouse, but my Setup seems to stop there.  I do not see the occasional hard disk activity, but I can get out my drive and have no complaints, so it seems to stop the disc at this point.

    I tried to create a new cd and I have the same problem.  If I run the disk then that in my current configuration of windows, he opens the settings and will begin the upgrade to win7.  I quit because I want a clean install.

    has anyone experience this problem?

    I have re-uploaded the file image .iso last night and will try to burn a new disc from tonight and see where I get with it.  If this does not work, I will try to boot from usb, but I really prefer to do just from a dvd.  also, I tried - r and + r media with the same results.

    Lytton, welcome to the forum,

    Simply remove the hard drive and the liquidator FRU number located on the sticker. Removal instructions

  • Battery ThinkPad Advanced Mini Dock (250410U) display will not extend

    I have a T400 (2764 CTO with a Radeon HD 3400), an Acer 23 "monitor and an advanced Mini Dock (part 250410U, model 2504). I am trying to expand the display of the T400 to the Acer monitor via a VGA cable. When I plug the monitor directly into the laptop, the screen extends. However, when I dock the T400 and connect the monitor to the Mini Dock, I can't get a signal on the screen. Any thoughts? Thank you.

  • The T9600 CPU specifications

    Hello

    I am looking to buy a processor spare parts for my T400 - 7417CTO, and I saw that Intel is the list of different codes spec for this processor (SLG9F, SLB47). Does anyone know what spec will work in T400?

    My system also came with a P8400, which has a lower TDP - 25 W as oppose to 35 W for the T9600. I am wandering if the heat sink / cooling set would be different.

    Any sugestions apreciated,

    Thank you

    Cosmin

    cosma12,

    We have a ThinkPad T400 2764-CTO, 12/08 production.  It has an Intel C2D T9600 (2.8 GHz, 6 MB L2 cache, 1066 MHz FSB, 35W) with 6 Stepping, Rev C-0 (reported by CPU - Z).  It is a very nice CPU - currently, we would probably have spec a C2D T9900 (3.06 GHZ; otherwise similar, but can't stand is not the "Turbo Boost").

    Not sure if you are clear, but the most recent T9600, revision E-0, is probably what you want.  The links attached will explain the change to Intel, originally dated 06/08/08.

    Just to be clear for the benefit of third parties, review/stepping CPU level may be specified or confirmed during the purchase of the ThinkPads (or for that matter, any computer laptop; not sure about people as reference Dell/Alienware or Falcon-NW). The average sales representative would know what you're talking about...

    Lenovo would likely produce systems based on inventories FIFO (first in, first out). now, it should be version E-0 the T9600 expedition.  Less reputable sellers could in fact older CPU steppings/revisions so inferior to dock source would result.  Assuming an earlier version had no obvious bug, how would be 99.9% of customers really know what is on board?

    I hope this helps.

  • How can you tell that your T400 has installed a DDR3 memory card?

    Hello world

    I got my T400 off ebay last week, and I do not know if my T400 has installed because I had this T400 (2767bk1) DDR3 memory for $800 and it seems new, but in an open package. I'm here to ask for your help, maybe there is a software that can perform a test to determine the type of installed memory card. Please let me know if there is a solution, thank you.

    the T400 can accept as DDR3 modules.   no other module does physically fit in the slot.

  • T400 own install problem for the graphics card hybrid

    I did a clean install on the T400 and installed all the drivers that are essential under the SWTools folder, but I see a problem with the card ATI will not work correctly.

    After installation from the folder videos and restarted the laptop. There is a sign next to the 'ATI Mobility Radeon HD 3400 Series' in Device Manager

    Under device status, I see the following error message

    "This device does not work properly because Windows cannot load the drivers required for this device. (Code 31)

    Has anyone seen this error? I tried to reinstall the driver again, but that does not solve the problem.

  • Could not find the owners booklet, T400

    I received my new laptop of T400 7417-cto, ordered from the factory a few days ago.   The only type of information describing the duties and the keyboard is considerably abridged two-sided page that comes with the computer.  I find no CD disc with information as a lot of products come with and don't have nothing found on the Lenovo site, even to support research... and find anything in this laptop, including research in the areas of ThinkVantage and Q score.

    I feel like a pretty stupid novice at this point on a FEW things... I do not even know what the three buttons just in front of the fingerpad of.

    Except for the inconvenience of not knowing how to deal with things like buttons and how to get an output series,... just half a dozen things... that is certainly a large notebook...

    I would appreciate your responses to me at: [email protected].
