T530 The bad memory

My T530 (i7-3720QM, 2.6 GHz, 4 GB) is 18 months old. Lately, some programs acted weird (region of a window will be unclear). Lenovo Solutions HW audit found nothing wrong. I decided to run Memtest86 + (v5.01) to check the memory and it has detected an error (TST:6, failing address: 0002fc7c5dc - Mo 764,4, good: 00000004, ADB: 00002004, ErrBits:00002000) after each pass. It seems that this error is in the lower part of the 4 GB on the MB. Before I start taking the unit apart, I was wondering if the 4 GB memory module is usable field or the RAM is welded directly to the MB and therefore, should be replaced by a repair shop. Thank you.

Hi Z, thanks much for the info re: HMM instructions to access the memory lower bar (address). Very much appreciated.

  • Increase the video memory of the A40-211

    Hi all

    I have the Satellite A40-211. The Intel chipset also supports all of the graphical stuff, so he needs a little more memory RAM as video memory. This is possible up to a maximum of 64 MB. The problem is that the chipset is now using a maximum of 16 MB of video memory, but I want to expand this to 64 MB.

    Where can I find the settings for this in Windows XP Home Edition?

    Thanks for all the help!

    Bart

    Hi, it s not possible to increase the video memory yourself!

    Let me tell you that your laptop is a dynamic memory management

    Your computer system reserved graphic only as much memory as it needs to accomplish all tasks running on your A40.

    .. dynamic video sharing .This is not bad, as I think!

    More info on your graphics chip basic find on pages of Intel.

  • 1.6 GHz 1.8 GHz vs. benefits of the turbo memory? a/b/g/n vs a/b/g

    Three questions really...

    Is there a significant difference in performance between processors clocked at 1.6 GHz and 1.8 GHz? If so, how is this affecting production of heat/energy.

    What is the advantage of the hd turbo memory cache and it interacts badly with vista?

    Is a comopatible n-network card as the Intel Wireless WiFi Link 4965AGN has significantly lower energy consumption that thinkpad atheros card? (I read this on another forum) Otherwise, I decide that I really have need compatibility n-network because few of these networks exist.

    The difference in speed is minimal between the two processors of the same generation, i.e. Core Duo or Core 2 Duo. The turbo memory benefits are realized only when you do not have a lot of ram for Vista, that is 1 gig or something. If you install 3 GB of ram (market now good enough right) the gain in speed is minimal with Turbo memory is minimal, while your 3 concert can still run under XP not the same for the Intel turbo memory. You can also get half of the allocation of memory Intel turbo using the functionality of Windows Readyboost in Vista, obtained using a fast SD card or a USB key. Wireless cards with doubled the speed of the g version N function, if you much sharing of large files wireless then of course it is useful, but if just use you it for surfing the net so I think 54 Mbps is fast enough.

    Looks like your cable is going bad. The data connection is different from the connection of load, so you can always load but have a data problem. Software cannot fix a broken wire.

    Run Memtest86 +: your computer passes this test?

    Memtest86 + is running from a floppy or CD and should eliminate or confirm if your one or more of your sticks of memory are bad or the values of the SPD in the BIOS are correct.

    Let it run for as long as you can: 2,4,6,8 or several hours (at least 3 full passes), if no errors at that time then your ram is OK.

  • block bad memory no. 2851

    I had some strange crashes recently on a no. 2851.

    When you check the crash logs, I found that the crash was due to a wrong address (supported or fetch statement) an exception.

    The exception occurs at the same address every time.

    Is there a way to isolate this block of memory for active memory / mark as unusable so the system tries to read?

    The memory module on the 2851 replaceable or is welded in the Mo?

    Hello

    No, you cannot isolate/disable the memory block and refrain the router to use it.

    the memory stick is replaceable on its expansion DIMM location:

    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now click on
    Driver update (this can do nothing as MS is far behind the certification of drivers) - then right

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as

  • Dell Inspiron 660 bad memory

    Dell Inspiron 660 has a slot of bad memory. It has two slots 4 GB in each slot, 8GB total. Only 4 GB show. I removed the ram and switched around and tried one in each location. My side slot on the left does not. Is this a common problem? It is expensive to replace the mother board? All the other fixes for this? I can put a 8 GB in a slot should I buy one?

    Thanks for all the answers to my questions frustrated! Debra

    II BIOS sees only 4 GB and any crack each RAM module is in it, then it looks like a motherboard failure.

    According to the specifications, 660 modules only supports 2 and 4 GB of RAM with a max of 8 GB total installed. So none is not a module of 8 GB.

    Several Inspiron 660 cards mothers available here and on the next pages of this site. And I guess there is always the eBay group own Dell spare parts.

    Only you can decide how much you want to spend fixing it. And always ask if a replacement motherboard is new, used, refurbished and warranty.

  • Setting the shared memory size linux

    Hello
    I'm a bit confused on the parameters of the kernel, can you please share your views on this one please.
    Shared for the tt in the linux kernel memory is calculated as follows:
    Shared mem = perm size size temp + journal + fresh size generals 7 MB

    but when I look at the linux sysctl.conf, I saw that there is a great value for sharing memory setting (default) as ~ 68 GB, then I think that I should not override/decrease this value. What is your opinion? Setting the value default (68 GB) helps my DB behave badly? Or by assigning the value calculated as in the equation makes them much faster?

    # Control the maximum shared segment size, in bytes
    kernel.shmmax = 68719476736
    kernel.SEM = 250 32000 100 100

    # Control the maximum number of shared memory pages segments
    kernel.shmall = 4294967296

    Thank you very much.

    The shmmax kernel parameter simply sets a limit on the maximum size of a shared memory segment individual. It has no direct effect on performance. In general, it should be set large enough to allow the largest shared memory segment you need to create but smaller then the amount of physical memory in the machine. Shmall parameter sets a limit of large system on the total amount of shared memory (all active segments added) can be allocated. It must be also, in General, lower then the [physical memory on the computer.

    If one is defined on more memory in the machine is not an immediate problem. However, in this case, it is possible to create shared memory that is larger than the physical memory of the system (as far as adequate swap space is configured), and if this happens then the overall performance of the system will be affected, probably seriously.

    Thus, work on what you need and set accordingly.

    I asked supplier what is the reason and that this was their response:

    "Memory is less, on vm servers, because there is an overpass (128-200 MB), which is deducted from the total memory, if you need more RAM you ask accordingly."

    This explanation does not seem right, because I think General cool knowledge happens on the hypervisor and comments should receive all the memory configured, if there are no limits set by resource management policies.

    They sent me a screenshot of VMclient which shows

    Use of the memory of the host: 855 MB

    Memory usage comments: 471 MB

    Is there a bad configuration on their side, or am I missing something here?

    There may be a missunderstanding. When you assign 1024Mo to the guest who is the amount of memory the burst enables the OS. Point.

    "Memory of the Virtual Machine.

    Each virtual machine consumes memory based on its configured size, more the additional memory overhead for virtualization.

    Configured size.

    The configured size is a building maintained by the virtualization for the VM layer. This is the amount of memory that is presented to the guest operating system, but it is independent of the amount of physical RAM that is allocated to the virtual machine, which depends on the resource (shares, booking, limit) parameters explained below.

    For example, consider a virtual machine with a configured size of 1 GB. When the guest operating system starts, he believes that it is running on a machine with 1 GB of physical memory. The actual amount of memory physical host allocated to the virtual machine depends on its resource settings memory and memory on the host ESX Server contention. In some cases, the virtual machine may charge the full 1 GB. In other cases, he could receive a small stipend. Whatever the actual distribution, the guest operating system continues to behave as if it is running on a machine with 1 GB of physical memory dedicated. "
