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:

but before you do this, I'd say to open a TAC case, if still under contract, to diagnose correctly that it is indeed a problem of bad memory/RAM.

  • problem with a block of memory in labview 2009

    Hi all

    I have "ERROR: MapLib:979 - LUT4 symbol" during the compilation process (lots of errors like this), and I discovered that the reason of my problem is block of MEMORY.

    To be sure that the problem is in this block, I did a very simple project in LabView 2009 (on FPGA Target PCI5640R) only with the use of this block you can see in the photo, as well as in file test_memory block.lvproj attached link: https://www.dropbox.com/sh/u87f1oihelmm4dq/Jo_6-bICSf

    I have a problem with compiling VI with this block, and I have so many errors like:

    ERROR: MapLib:979 - LUT4 symbol
    "window/Thatcher/n_00000036/nSCTL_00000013_00000014/n_000000A3/cOutLoc<0>1.
    (output = window/Thatcher/res000001ed_wi<2>) is the input signal
    "window/Thatcher/res0000020d_wo<1>" that will be deleted. See Section 5 of the
    Map a report file to find out why the input signal will become conveyors.

    or

    ERROR: MapLib:978 - LUT4 symbol
    "window/Thatcher/n_00000036/nSCTL_00000013_00000014/n_000000A3/cOutLoc<23>1.
    (output = window/Thatcher/res000001ed_wi<25>) is an equation that uses
    input pin I2, which no longer has a connected signal. Make sure that all the
    the pins used in the equation for this LUT are signals that are not cut
    (see Section 5 of the report file map for details on which signals were
    adjusted).

    Entire report, you can see in the file report.txt on the attached link.

    I would appreciate if someone could take a look at my problem with simple project and suggest me a solution.

    I'm really stuck with my biggest project which need to have this memory block.

    Hi all

    I find a sollution to my problem.

    In memory-properties-general-setting up, I changed the block to look up Table memory, and I compile memory.vi and run it successfully.

    I did change as you can see on the picture:

    Just, can you tell me is it all "bad properties" and limits the use of this type of memory (Look up Table) of the implementation?

  • [Labview FPGA]: block of memory use Xilinx HDL integration node

    Hello

    In my project, I would be developed my own VHDL module and integrated in my project of LV FPGA with a knot of integration.

    But for an evolution of my code, I wonder if it is possible to use in my own code VHDL, Xilinx library (as a block of memory).

    Thank you.

    You can use any Xilinx IP (or IP and others) in your external code. For example, if you generate a block of memory using block memory generator you can instantiate this IP in your own VHDL.

  • Write problems block the memory of the host

    Hi all

    I work with a sbRIO 9639 and followed what I thought to be the recommended procedure to write in the block of memory to the host computer via (see diagram attached host and FPGA implementation). However the operation of the aforementioned code does not actually change the memory and what is available is rather just the previous values (which are persistent).

    However, I am able to write to block the memory directly from the vi FPGA (one) and get the results that I would wait if I then run the host after writing the correct values. In fact, I can now see these values from the host using the read/write Protocol.

    Does anyone have an idea on the cause of this problem? I followed the implementation to write and read from the memory in the examples, but have not found any success.

    I can't possibly comment code NIs because I don't know who wrote, why and for what purpose.

    You can write to the control whenever you want, but if you don't actually read it yet (mark) then you're never going to see the new values.

    Polling station should be avoided on the host programs, but it is not inevitable and normal on FPGA.

    Put the entire program within another loop, and then try again.

  • 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.

  • Equium A60: Bad memory value appears

    My toshiba satellite A60 have only 448 MB of ram, it shoukd have 512 what can I do?

    Post edited by: tommaz

    Hello

    In my opinion, the lower value of the memory appears in the properties of the BONE because of the graphic card of 64 MB shared memory.
    This card use a part of the main memory and so you will get a different memory value.

    If you add the 64 MB to the 448MB you get 512 MB. So everything is ok with you memory modules.

  • 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.

  • Map of bad memory too bad vid

    I have an opportunity d530 cmt, p4 3 GHz, 1 GB of ram. I installed a mod pc2700u 512 MB memory, windows started normally as a first step, I guess that it's called the splash screen, but when the screen with user accounts came on, the screen was blurry and the color has changed. No red shows just blue and green. I uninstalled the mod memory, but the prob persists. Damage the internal video card or monitor? Any help is appreciated. Thank you.

    Hello:

    I put a 128 MB nVidia GeForce 6200 card in one of my friends, and also a card of 128 MB Radeon 9600 in another, I had.

    They must be AGP cards.

    You could probably go to 256 MB memory for these cards.

    You should be able to find those used, but tested and functional on eBay.

  • Bad memory

    Hello world

    I have a problem with the amount of memory that the collector is a report in some servers with Windows server 2003 IA64, the servers have 16 GB and 8 GB of ram, but reported the collector 1 052 670 MB. The problem is that in the consolidation report that systems appear as they are not candidates to codify.

    What do you suggest me me to check on the collector or systems to solve the problem?

    Thanks in advance,

    Hi everyone, I just remove the host from the inventory of capacity planning and add it again and it detects the correct amount of memory.

    Thank you all.

  • The State of health does not detect bad memory

    Hey everybody,

    I'm running 3.5 update 4 on a Dell 2950. The

    problem I have is that I get a defective DIMM message on the LED of the

    Server, but the parser memory under the health status is green and happy.

    Any ideas why this happens? I noticed on all of my boxes of the host

    You can not expand the section of memory under State of health; You can

    with all other sections. It could be related? Any thoughts?

    Thank you

    Kevin

    What is the code?  I had E2110 MBE (Bit error memory) which do not show in the State of health.  In the past, I used OpenManage on the ESX host.  The company I am now is not installed and I don't know if they will allow it or not.  My problem is that my mistakes were in equipment that located on our site of DR unmanned and we did not know the errors until we are to test!

    Kind regards...

  • Blue screen and bad RAM memory?

    My MBP 2011 early all just stopped working yesterday, it worked very well without any problem of performance for the last 5 years, and then suddenly a blue screen (of death) and it has problems starting.

    He will ring the Bell to start, display the bar loading and Apple, and then there will be a glitch on the big screen (horizontally) 1 inch above the Apple, after that, the fans speed up and all that I see a gray screen, not user interface.

    I zapped the PRAM/MSC and tried the unique memory sticks, I have no spare RAM on hand, but who will order soon.

    Tips to solve this problem?
