[W520]: who is running 32 GB of ram?

Who is 32 GB of RAM running in their W520? Can you please post the brand and model # of the RAM used?

I tried to RAM Kingston, Crucial, Corsair, and own internal Lenovo (Samsung) 8 GB of supported modules in my W520. The W520 has problems starting when "Integrated graphics" is selected (and OS of Optimus detection is disabled). It starts very well in dedicated graphic mode and Optimus. I have the latest version of the BIOS. The problem exists on Windows 7, Windows 8 and every flavor of Linux.

The problem is that as soon as the graphics subsystem is initialized in Windows or Linux, the CPU gets attached to 100% usage, the system is extremely slow and CPU fans operate at full breath. I tested the RAM and the processor in the system of another manufacturer and all is well. I believe that the BIOS has a problem (which would be supported by a lot of people having this problem) or my specific motherboard is defective. I want to see if I'm the only one to have this problem so any help would be appreciated.

This post is a continuation of a problem, I spoke in this thread: http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-Intel-HD-3000-iGPU-broken/td-p/821371

  • Satellite Pro C50-A-1E4 running unstable with new RAM modules

    I have the above machine and that you have upgraded the RAM (up to 8 GB) a long while ago. Normally I have upgraded the BIOS if there is a new version.

    However, for some so that my machine was unstable, and this is due to the RAM running at the XMP1866 of the machine (933 MHz) instead of the rated CPU 1600 (800 MHz). I have attached a screengrab of Piriform Speccy to report.

    There is no 1.40 BIOS UEFI framework to adjust the RAM timing and so BIOS supports data SPD incorrectly for CPU ID.

    I'm unable to locate earlier BIOS to check if this pattern is repeated, but it took more than a year to display fault so that the machine is out of warranty. If I put small sticks of RAM 1600 system seems stable.

    However, I bought the RAM to use. Now I am unable to test if RAM is faulty because she will not pass Memtest (blocking or crash on) but I'm not sure if instability of the system is defective cause of system being OC because of the BIOS or RAM.

    The question that he is perfectly for about a year before displaying the errors. BIOS should correctly detect the speed of JEDEC standard data in the EEPROM. He does not. I often ran "overspec' memory in other PC without encountering this behavior. It is only troubleshooting that made me aware of this gap.

    RAM is Crucial Ballistix 8 GB-1866 BLS8G3N18AES4CEU.16FE

    If I put small sticks of RAM 1600 system seems stable.

    I doubt that it is a BIOS problem...
    First of all, you can not use any module of RAM... you must use a fully compatible modules and as you probably know, not all commercially available RAM modules are fully compatible.

    As far as I know if upgrading RAM that Toshiba recommends the use of these modules.

    4 GB DDR3 - 1600 PA5037U-1M4G
    8 GB DDR3-1600 PA5037U-1M8G

    The specifications are:
    Memory speed: 1600 Mhz PC3-12800
    Capacity: 8GB
    Pins: 204 SODIMM
    Type of RAM: DDR3 SODIMM
    Rank: Rank double
    Latency (CL) CASES: CL11
    Voltage: 1.5V

    I recommend you use the modules that meet exactly the same specifications.

  • Satellite Pro 4600: sometimes applications stop running with the new RAM

    Hi all

    I was wondering if anyone out there can shed some light on my problem. I've recently upgraded for an extra 256 MB on my Satellite Pro 4600. The laptop showed the increase in RAM. Since the installation, for some reason any after running for awhile applications (this varies between 10 minutes to a few hours like laptop start up), applications stop running. I can not open new applications. When I restart, I can run the applications in my laptop as usual again.

    I received my offtek RAM. Manufacturer part number is the same as specified in the manual of my laptop.

    Please someone has an idea?

    Mocha

    Hello

    Please check the number of PA of the 256 MB chip, the number of PA is properly PA3005U - 1 M 12.

  • Anyone WHO is running 2 monitors from lightning on a Mac Mini (Windows 7)?

    Did someone drive actually two screens Thunderbolt out of a Mac Mini (late 2014, complete the form below) in bootcamp with Windows 7?  Apple says you can do (see below), I couldn't, and I'm pretty technically competent.  Windows 7 in Bootcamp runs absolutely perfectly, I used all the latest drivers and drivers from Bootcamp OK/set of tools for my machine (Apple publishes sets of specific tools for each machine).  Windows just absolutely does not see the second monitor Thunderbolt, I went through each option of control panel in Windows 7.  To do this, of course, works very well under OS X.  I am currently using Parallels to work around the problem, but the decline in performance is much too tight, and I need to run Windows directly in the training camp with two monitors.  Help, please.

    Are the two monitors of TB Garland or connect directly to the Mini?

  • I have a pavilion a6863w and currently runs 7 GB of RAM. My computer will handle 16 GB max.

    Ctdmsims Hello, here is a link for your system specs. The specifications show that the system supports 4 X 4 GB memory modules. However, these 4 GB modules should most likely be installed at the same time and not mixed with other memories.

    HP systems generally wanted to work, or work well if, with the mixed memory modules.

    I searched for some 4 GB modules that are compatible with your system, I was unable to locate anything.

    If you managed to locate a module of 4 GB, it would almost certainly not compatible with existing memory in your system.

    Just some thoughts.

  • How to create a banner size mouseover who starts running only at the end (in Adobe Edge animate)

    A banner general practice is to have the entire banner be clickable as well that trigger the mouseover and mouseout/mouseouthandler().

    In flash, you would do an invisible button that captured the events, and then looks like an internal chronology of a chart of the CTA to play and which would scale upward.  I would also (in the main scenario where all the basic animation) a fade in opacity to the top of the CTA at the end Flash would allow me to set the rollover and rollout on the last image, so no features a rolling code would execute while the button was in invisible state.

    Along the busy, I know how a symbol, with an internal chronology which can evolve the assets. I know how to use the action of another layer to speak to this chronology of symbols and to play and to reverse the trend.

    But I can't understand how the mouseover and mouseout/mouseouthandler() code to run ONLY when the banner has played through the main timeline animation.

    Thank you.

    make a layer/button which is at the top with a transparent png of the size of your project. First frame of the main timeline, the value to display last image off the coast, it appears on the value.

  • Months "Pavilion DV7 notebook" running VERY slow

    Had this laptop for the summer holidays, maybe there are 8-10 or more weeks and have had no problems with it so far.

    My laptop is so slow that I have something like 'my documents' loading can take 5 minutes and then hang. I write this from my phone my computer now runs so slowly that google chrome loading isn't really worth a try.

    My characteristics are (and it took me about 10 minutes to load).

    -5.4 windows experience index
    -Processor intel core i5 - 240 M @ 2.50 GHz processor
    -6 GB of RAM
    -64-bit operating system
    -windows 7 Home premium

    The task manager says I have my uses CPU is around what it would be before the problem (at least I think that's normal) but I am using 1.67 GB of memory, when nothing does not load, is - it normal I never really watched who before today.

    I did a 'system restore' who got running again for 30 minutes before it further deteriorated.

    I defragmented my drives.

    I deleted temporary files and run "cc cleaner".

    Pressing f10 at startup I got to perform a free hard drive scan (I think that's what it was called) - the result of this test was: "full hard drive 1 (305)"-I guess it's bad.
    On the same page, there was also a "memory test", going on the computer.

    I did a virus scan anti by using "avira".

    Any help you can give me would be welcome. I am a child of 15 years and it took me something like 30 weeks of my paper round of savings to buy this laptop. My mom and dad will kill me, so if I can fix it before I have to tell them, that would allow me to save a lot of grief.

    Sorry if this is the wrong section.

    Hello

    305 error code is a complete failure of the (Full) drive self test failed and would indicate that hard is defective and must be replaced.  This is also consistent with the problem of slow performance.  It is just the failure of a component and could happen to anyone.

    Your laptop must be under warranty, contact HP and arrange for the replaced disk - you can check your warranty status here.

    If you live in the United States, contact HP here.

    If you are in another part of the world, begin here.

  • HP ProBook 6550 portable PC b: Re: RAM laptop HP ProBook 6550 b Upgrade issues.

    Info on my ProBook 6550 b HP PC:

    2 x 1 GB RAM (1.86 GB usable)

    System type: 64 - bit operating system.

    Windows Pro 10.

    Query: I bought 2 x 4 GB RAM DDR3 1333 MHz 204-pin SODIMM Unbuffered of CCL Computers Ltd. After searching for the correct specifications on here to upgrade my RAM.

    I installed this new RAM carefully and booted up my laptop, only to be greeted by a blank screen / black.  I have re-installed the new RAM and rebooted my laptop, leading to the same result.

    I contacted CCL Computers Ltd, who recommended that I return the RAM to them for testing. However, they also mentioned that I should contact the constructor (HP) and ask them - your "QVL" (list of qualified suppliers) for successfully piloted ~ known RAM.

    So, with the above in mind, can you recommend a tested / experienced 4 GB of RAM running on my laptop, please?

    Already mentioned somewhere on one of these forum pages for "Corsair DDR3 4 GB of RAM of the laptop (CMSO4GX3M1A1600C11)"

    I'm also upgrading my laptop to SSD HARD drive.  I visited your forum pages and read that an SSD with a capacity of 250 GB is the optimum size.  Can anyone offer any known SSD fact / correctly upgraded for a laptop of my setup, please?   (See the top of this message to my HP ProBook specifications.)

    Looked at your comments and recommendations will be highly appreciated.

    Thanks a lot waiting for your answer.

  • Random BSOD W520

    Hello!

    Not long ago, I bought thinkpad W520

    I7 2760QM, 16 GB of RAM, 160 GB Intel SSD, wireless advanced, reader of fingerprints and bluetooth.

    After the installation of the system recovery partition I started getting the BSOD.

    Don't reinstall operating system, making the clean install of Win7 with latest drivers on the web gave no results.

    Reasons for bsod as written are different all the time: IRQL..., PAGE FAULT IN... and so on.

    I searched through this forum, it seems that similar problems wo people had problems with RAM.

    Then I ran 5 cycles of windows RAM checking tool and full memtest86 +, which both reported no errors.

    I tried to use the driver verifier, but he can't find any faulty driver and reports anything from the core of windows up to antivirus.

    Finally, I want to mention that BSOD happen more often when running on the battery. In addition, BSOD occur usually just after windows has loaded. It can happen up to 3 - 4 times trying to start, but then it may not show up for a day.

    Yes, I have 3 years warranty but I'm away from the country where I bought this phone and really need this job to the machine.

    Can anyone help? I can post dumps memory on the crash, if necessary minidumps.

    Thanks in advance.

    Writing to tell you that the problem was really with RAM

    I got 16 GB installed the same Samsung RAM. There are two faulty RAM sticks under the keyboard. Maybe it's motherboard problems, but have not yet tested. The remove solved BSOD problem.

  • Can I run time after effects CC & CC 2014 on the same machine?

    I've recently updated AfterEffects CC-AE CC 2014. I use Cinema4D lite extensively, but I am unable to use the new Cinema4Dlite R16 with AE CC 2014. My question is:

    I'd be able to run both versions of AE and Cineware on the same machine?

    And if yes, why I can't use C4Dlite in CC 2014? (C4D lite is open, but I'm unable to select one of the buttons or anything in the menus).

    I recently worked with a client who was running CS6, and I found that to make a compatible with CS6 AE CC 2014 file, I needed to export from 2014, then export again CC, hence the need to run both.

    I really appreciate help or solutions that anyone can offer to this.

    I use Windows 8.1

    And my machine features:

  • All of a sudden can only run a virtual machine on a workstation to 12G, used to be able to run at least three

    After years of use of my computer, I have a problem suddenly as the likes of which I've never seen elsewhere.  On a machine that was able to run three virtual computers, I now get error messages when I try to run more than one.

    The message I get is displayed as an attachment.  It indicates only 1192 MB is available for the second virtual machine, I try to run.  See error message when you try to run a second virtual machine.png

    The preferences that I set myself for VMWare Workstation show until 9210 MB should be available for virtual machines.  See the preferences.png workstation.

    Who is running when I try to launch a second is set to use 2 GB.  See machine running virtual preferences.png

    Resource monitor shows also that it should be 5376 available MB.

    I'm puzzled.  What could happen?  How can I solve this?

    I am running 8.0.1 build-528992.

    find your config.ini file
    Win7: C:\ProgramData\VMware\VMware Workstation\config.ini
    XP and 2003: C:\Documents and Settings\All Users\Application Data\VMware\VMware Workstation\config.ini

    and change or add these 2 lines
    prefvmx.useRecommendedLockedMemSize = "FALSE".
    prefvmx.minVmMemPct = '0 '.

    These settings should allow you to assign 12 GB of RAM or more for your virtual machines
    If this is not the case - I would switch to 7.1.4

  • Can I add more than 4 GB of RAM for my 37 s Inspiron from Dell?

    I am running Windows Vista Home 64 bit. My computer is now about four years old, but I don't have the money to drop on a brand new computer. However, I found a graphics card that must adapt to the inside and the race (it was recommended to the user who is running a system like mine on another post on the forum). Now, I just need a RAM upgrade, because I do not think that 4 GB enough for me anymore. Once I update the graphics that I intend using this PC mainly for gaming. I did my research and I think that if I upgrade the graphics and RAM, I should be able to do what I want to do with this computer. Ideally, I would switch to 8 GB of RAM, but I'll settle for 6 GB. I just need to know if it is possible to operate this computer with more than 4 GB of RAM, because I've not heard elsewhere.

    It is not a model 37 s, but if you mean the 537 s, the maxium of RAM is 4 GB. http://www.crucial.com/store/listparts.aspx?model=Inspiron%20537s&cat=RAM
