Can satellite U400 - I switch to a quad core CPU?

Hello

I recently bought a Satellite U400, and I was wondering if I could move the CPU on a quad core processor.

* is it physically possible? that is, fit the plug? It seems that the Q9xxx and the T5750 share the same socket but maybe he ore other parameters to look for.
* How can I check if the motherboard supports the Q9xxx? I should probably need a BIOS upgrade: what is the difference between a win32 and win64 bios? I could guess that has something to do with the target OS, but should I assume that the "win64" adapts to any OS 64-bit-ready (i.e. linux, * bsd)?
* are there significant losses in the battery life?
Thanks in advance

> in any case, is there a way to check if the BIOS / motherboard supports a quad core CPU?
You will not find any information about the BIOS and CPU support on Toshiba pages.
The BIOS has been designed the U400 and CPU that is equipped with the U400 series.

I put t know which chipset your U400 is compatible but my U400 supports Intel GM965 chipset, and the Intel GM965 supports the same features as Intel PM965 chipset.
http://www.Intel.com/assets/PDF/datasheet/316273.PDF

The Intel PM965 chipset supports the processor Intel Core 2 Duo Mobile for Mobile Intel 965 express chipset family.
The Quad core CPU is not mentioned. So, it seems that these processors are not supported!

Cheers mate

    Hello

    This Quad Core CPU is an additional processor that is not always in use.
    It was designed in the order using the main processor in some of the media process.
    For example, the Quad Core CPU works during the encoding or decoding of certain video standards. If you want to change it the standard of the video, the Quad Core CPU helps you complete this quick procedure.

    In addition, it improves the quality of the video (not HD). So, theoretically, you can view the videos in HD quality.
    Of course, you won't get the same quality as a film that has been recorded in full HD, but the Quad Core helps you improve the 576i pictures.

  • Can games i run well with an a4 5000 quad core cpu AMD processor?

    Hello, I have an aser aspire laptop e1 - 522 and I want to use it for some games. If everything is fine, I'll be able to get a gaming pc but if I usually I want to know this: I have an amd a4 5000 apu quad core cpu and it has 512 MB memory syestem grphics. I have also 4 GB of ram at 800 mhz. If I move to 8 GB 1600 mhz ram I'll be able to... play cod 4, 5, and 2 setting ultra 720 p (1080 p maby) at 40 to 60 fps. also I want to be able to play transformers wfc and jib to medium to low 720 p at 40-50 fps. my laptop apu can do with ram upgrade?

    Thank you.

    Looks like your computer is more than capable of some great games. If you were to do something, my first upgrade would be to double your RAM 8 GB.

  • Unique use of VM CPU on the system dual quad core CPU

    My environment: two machines, a Dell 2950 with dual quad core CPU, running ESX 4.0 Advanced.

    Machine 1 to several virtual machines on it.

    Machine 2 has a virtual machine that hosts a .NET/IIS web application built by an external supplier. The web application is having performance issues (users requests take a long time to complete in some cases). I suspect, without having yet done an in-depth, analysis is that the web application is not well resolved/optimized/designed.

    The declared owner of hardware requirements is exactly how Machine 2 is - dual quad core CPU. However - There's the rub: I did not understand if a single virtual machine running on this computer can actually use all the resources, particularly CPU resources, on the machine. And my application provider takes that position - since we have not met the minimum hardware requirements for the application, which can be the cause of the poor performance, which means that the seller has no responsibility for the performance issue.

    I tried to understand/consider the Enterprise more than vSphere edition, because it seems possible that only this version of vSphere would allow me to assign all the hearts of all the processors from the server to the computer virtual one. However, this seems like overkill, and also, after some reading on the SMP of Enterprise Plus features, it seems, as using SMP can help in some cases and poorly in others.

    Right now I'm looking to remove vmware Machine 2 and just install the application on the machine, in order to eliminate the possibility that vmware restricts the application to all physical resources (CPU). But I thought I'd ask a glimpse of this group first.

    Any input appreciated.

    Thank you

    Each physical core (or "core" hyperthreading) is considered to be one vCPU. You will therefore 8 vCPUs in your system (assuming hyperthreading is not enabled). However, you can approve vCPU which means that you can run several virtual machines than available vCPUs. This is because you do not usually have the VMs that need all the power of the processor, and they can be used more efficiently with VMware planning the vCPUs.

  • Quad Core CPU - how is used by workstation?

    I just bought a new machine with a quad core CPU.

    I know that Workstation only supports a maximum of two hearts. What I don't know is: what does that mean? That means, that if I would have four virtual machines running...

    1. they all do they share only the first two nuclei of the four cores available?
      .

    2. or each of them uses a distinct nucleus? (or two hearts arbitrary if I would assign two to a virtual machine)

    Please enlighten me!

    No, my computer supports a maximum of two virtual processors. All physical hearts are deemed be a CPU for the guest operating system. So if your have four hearts in your application assigned to the guest host and two vCPU it there always uses two cores at one point of time.

  • Quad core CPU in x230T?

    I realize that even if it were possible, cooling would be the main problem. But I'm curious to know if, say, an i7-3612QM might work in the socket on the mobo. It is rated at 35W, just like the i5 - 3320 m currently installed in mine. Via Intel ARK, they should both work in the socket on motherboard of the x230T 988.

    All X series ThinkPad, compressed or not, have the welded CPU on the card and not recessed them. This has been the case since the time of X 20, nearly 15 years ago.

    So no, you can't swap the CPU unless you are in possession of re-balling appropriate as well as the skills to use it.

    In addition, BIOS support for a quad-core processor must exist, which I doubt is the case on X series.

  • Should I expect the 64-bit version of 32bitor for my Windows 7 Ultimate? I have a Quad Core CPU.

    32 bit 64 bit. Windows 7 Ultimate. Quad Core Samsung.

    In general, it is preferable to use the 64-bit version, unless there are some very special reasons of not (for example, a critical piece of hardware that offers only one driver 32-bit).   He runs the 32-bit software and also allow the possibility of using 64-bit programs.  The 64-bit version can support more RAM and provides a path for growth in the longer term.

  • SOS - NVidia Chipset, Vista 64-bit, Intel Quad core CPU & > 4 GB RAM questions

    Hello!
    One cannot explain the question about more than 4 GB of RAM, 64-bit Vista Ultimate, NVidia Chipset and Intel Core 2 Quad CPU.
    I have a MSI P6N SLI Motherboard (NVidia Nforce 650i SLI Chipset) with 6 GB of RAM DDR2 800, Core 2 Quad Q6600 CPU, 2 x GeForce 8600GT in SLI Mode.
    32 bit Vista ultimate works fine with my PC, but whenever I try to install a 64-bit windows vista Ultimate Edition, a BSOD with the STOP error message is displayed. Not much happens if the RAM is reduced to 3 GB. The most strange, when I tried to install Windows 7 in this same configuration, there was no this problem.

    Kind regards...

    Hello

    There is an error in timing known when installing Vista 64 bit on a system with all the ram slots 4 full on a card mother dual channel. It has nothing to do with the size of the total ram. The simple solution is to install x 64 with only the two bench 0 Visa slots filled, and then add the other two sticks back when the installation is complete.

  • Can satellite P300 - I switch from 32 to 64-bit Windows?

    Hello
    Soon I'll receive the CD with Windows 7 and the drivers for my laptop (P300-20 b). I warned for Toshiba Windows 7 Upgrade Option Program. And currently I have Vista 32 bit.
    Can I switch to Windows 7 64 bit of Vista 32? And another question, what is the optimal amount of RAM for 64-bit system? Currently I have 3 GB.

    Thanks for the reply!
    Kind regards
    Gregory.

    Hello Gregory

    Unfortunately, you can't switch from 32 to 64 bits. If you want to use the 64-bit operating system, you must do any new installation. Install Vista 64-bit using the recovery disc or HARD drive recovery option.
    After doing this update install Win7.

    Optimal RAM? You can use it with current 3 GB, but if possible you can upgrade RAM and more powerful laptop. ;)
    Laptop specifications that your PSPCCE can be upgraded up to 8 GB of RAM. Not bad.

  • Can satellite U400-112 - I retrieve C partition only?

    OK, so I want to recover my C partition only, and "Repair my computer" in the start menu does not work for some reason, I get an error saying: failed to load windows...

    I have the recovery DVDs, but if I use it, it says it will restore my entire hard drive... !
    Is there a method that will allow me to reset the C partition only to factory settings?

    PS. I still have the factory Windows running.

    Thank you for reading

    # You can grab the C partition only if you start the procedure of recovery disk using F8 and disturbances of my computer.

    When you use recovery DVD will be erased the entire HARD disk, partitions will be created, copied to the installation, and then the second partition recovery image will begin.

    After doing this you will have own OS preinstalled and F8 option works again. Don t do something with folder HDDRecovery on the second partition. Best thing you can do is put the file in invisible mode and you have not think there is. If a problem occurs, you can install OS again and again. Of course only the C partition is removed. All data saved on the second partition will always be there.

    For the moment, you have just one option back up all your important data to an external device and install the OS by using recovery DVDs.

    Good bye

  • Imitate the Quad Cores

    Hi all

    I hope I have explained this properly... we're all here:

    We were asked to bring a 2 pieces of software in our field who will sit to ESXi, but requires a QUAD Core processor each... If I allocate a vCPU to this distribution of stocks of high box will not imitate multi hearts it will be? This will allow only that he calls the time CPU. That Said if I can get a server with hyperthreading I could then put affinty cpu? and this would allow the software see 1 quad core cpu?

    I hope I explained this corretly

    Only closer image aping is assiging four vCPUs to VM - the ESX host sxhedules each vCPU core or Hyperthreaded if HT is enabled - which application is this > from my experience, I think you will find the application will be fine with a single vCPU.
