Upgrading memory on the PXI-8105 controllers and PXI-8106

Hello

I've recently upgraded the memory of three PXIs; one with a PXI-8105 controller and two with the PXI-8106 controllers.  Both the 8105 and 8105 can have a maximum of 4 GB (2x2gb) DDR2-677 (PC2-5300) (see links below).  However, on the three systems, both the BIOS and the o/s only see 3.3 GB.  No idea why this might be the case?

I tried to Flash the BIOS (v1.4 on the two PXIs), but without success.

We use COTS memory (i.e. not purchased NOR) but I would be badly pushed to believe it is the cause of the problem.

Thank you.

I don't know about the BIOS reports less than 4 GB. Here's a blog post that best describes what I wanted.

  • How to determine the amount of memory on the PXI-5124

    Can I determine the amount of memory on the PXI-5124 visually? I don't see a reference as 778757-02 on the map.

    Hello axiomtest,

    There are two stickers on the back of the card (including one with a barcode) and the other without.  The part number is that without the bar code and from there, you can search your memory option on our Web site.  If there is no sticker on the card, which looks like yours have been removed, then use this example of community in LabVIEW to determine the size of your card.

  • On the PXI-8106 serial port connection problem

    Currently, I am trying to connect to the serial port on the PXI-8106 via RS232 module. However, when I try to run the Test VI opened for COM1 MAX (PXI Remote) running on a PC, I received an error like below:

    Returns the status code: 0xBFFF00A8

    Name of the State: VI_ERROR_NPERMISSION

    Access to the resource or the remote machine is denied. This is due to the lack of sufficient privileges for the current user or the machine.

    Right now I'm just a just loopback test to ensure that the interface for device is working before you start my labview code. I'm not sure what the problem is exactly, if it has to do with the PXI or PC. Could you please suggest a few solutions to this topic?

    Thank you.

    I managed to understand. It did not work on the right platform.

  • Upgrading memory on the NB550D - 11 d - 4 GB of RAM are possible

    To anyone who thinks of a memory upgrade on the NB550D:

    The NB550D supports up to 4 GB of memory, not only 2 GB as mentioned by Toshiba in their specifications.
    Upgrade memory to 2 GB is _only limited_ by the pre installed Windows 7 Starter OS, and not by the netbook itself.

    I use Linux Mint 11 Katya, 64-bit and my system works perfectly well with a 4 GB ram module. If you want to use the full support for 4 GB ram, get rid of the Win 7 Starter operating system.

    Specifications for more memory ram volume are DDR3 1333 MHz PC3-10600 SO-Dimm. I chose a 4 GB of Corsair module, because of the guarantee of 30 years of offers from Corsair.

    It took me a while to find this out hope, that this will be a help to all those who are just as secure as I was how to upgrade memory NB550D. Good luck. (o).

    Thanks for the comments

    Also it of important to mention than the 32-bit systems (not serious if its Linux or Windows) would recognize only 3.2 GB since it is a limitation of 32-bit
    So to use all of the 4 GB RAM 64-bit system is required.

  • Upgrade memory on the Satellite Pro A200

    Have two cell phones of #PSAE1E - 00T002EN Satellite Pro A200 and wanted to know if I can pass the 2 x 1 GB memory 2 x 2 GB?

    If I understand correctly what ask you, you want to upgrade memory of 4 GB laptops.

    Well, I think that it s is not possible.
    The Satellite Pro A200 supports maximum 2 GB of RAM (2 x 1 GB), then you will not be able to use 2 x 2 GB modules.

  • Upgrade memory to the Qosmio F20 problem

    I just bought a Laptop Qosmio F20; It has 512 MB RAM DDR2 pc4200 533 MHz in standard. When I added an another 512 MB of ram the laptop turns on but the screen is blank, when I installed them separately, they work very well sound when I pair their place is happening, they are of the same manufacturer (Samsung) and the same type & speed.

    Please could someone help me with this, because I am intrigued. This laptop does support 1 GB memory 2 x.

    Hello

    The laptop supports without a doubt memory 2 x 512 MB sticks.
    You can upgrade the memory for max 2 GB (2 x 1024 MB)

    As far as I know Toshiba recommend using these modules:
    512 MB DDR2-400/533 (PA3412U - 1 M 51)
    1 GB OF DDR2 400/533 (PA3411U-1M1G)

    About you, problems with memory, it seems that both modules are not compatible I know that sounds very strange because you use the same modules (as you say).

    I recommend to replace the new module and you should check if the laptop runs correctly with other new module

  • Upgrade memory on the Satellite L300

    I bought a L300 satellite in August 08 in Australia. It came with a single module of memory 1 GB which is now inadequate.
    I got 2 x 2 GB modules but cannot make it work with the two climbs. Reports of the mounted but 4 GB Vista BIOS restarts the first time then blue screens. Ubuntu Linux crashes after loading of HAL.

    If only one module mounted it works OK and it does not matter which module is used.

    Any info on this would be most appreciated.

    There is not some special info that you can get here.
    With RAM upgrade is important to use the 100% compatible modules and also the high quality products of Toshiba or Kingston.

    Many people have reported on the same problems using certain products without name at low cost.
    2 GB compatible RAM has PA3513U-1M2G part number.

  • Question about upgrading memory on the Satellite L20-181

    Hello

    The recommended minimum is memory for Windwows XP 256 MB and I don't understand how the company could get far notebook sale with integrated graphics with 256 MB shared system memory.

    In any case, I want to improve my Toshiba and my intention is to buy 512 MB more memory, such as http://www.orcalogic.co.uk/asp/prodtype.asp?prodtype=20049&ft=m&st=3

    Will it work properly with 768 MB or I will only buy the same pair: 256 + 256, 512 + 512?

    Thank you very much.

    Hello

    First of all, you are not right. Windows XP also works with the low value of the memory.
    But of course it depends on memory so the OS applications will run more rapid or slower.

    However, the fact is that you can upgrade the memory on your laptop and it doesn't mater if the modules have the same value of memory or not.
    In this case, the laptop came with 256 MB and you can install detox the second module of 512 MB memory.

    PS: I recommend installing the 512 MB in the first slot and the 256 MB in the second Bank.

    Hello

    There are several ways to know which module memory is compatible and supported.
    You can use a diagnosis too like Everest, you check the user's manual or from Toshiba Web site for details or you will contact the service in your country for support modules.

    I'll try to answer the question: the Satellite A50 should support PC2700 DDR - RAM as the following:
    PC2700 256 MB (PA3311U - 1 M 25)
    PC2700 512 MB (PA3312U - 1 M 51)
    1024MO PC2700 (PA3313U-1M1G)

    Now it s your choice. You can also google for offers
    By the way: visit the Toshiba site Options & accessories. You will find compatible parts

  • Upgrading memory on the Satellite L500D - 13 c

    Hello!

    I own a laptop Satellite L500D - 13 c and I am considering upgrading memory 2 x 2 GB 2 x 4 GB RAM. According to a specific model list on the accessories compatible with the 4 GB of PC2 DDR2 (800 MHz) memory, item # PA3670U-1M4G, is recommended by Toshiba.

    What I want to know is if this module specific memory (with article # PA3670U-1M4G) is the only compatible module for my laptop or if I could get and buy bars of memory corresponding (and hopefully cheaper) with the same specifications (800 mhz, etc.) without damaging my PC?

    TI would appreciate some advice on this.

    See you soon!

    Hello

    You can also buy another module of memory with the same specifications. Fact is that some modules at low cost and without name can be initially responsible for compatibility issues. It may happen starting cell phone s display will be remains black.

    Therefore I recommend you to use high quality modules and Kingston is one of the best manufacturers of memory modules.

    I understand that you want to save your money but you buy it now and it should work properly.

  • Memory of the PXI - 6562 Max per channel

    I have two questions.

    I have a PXI - 6562 and a data set is 256 MB (32 MB). I want to send the data in this dataset on a single axis of I/O serial. basically, I would like to spend my little of a set of data at the same time on both edges of the clock on an axis of IO. I don't like on the other IO pins. Is this possible with the PXI-6562 or all bits in each octet in the memory of the card corresponds to a specific channel.

    If I can't send my data in series then I will accept that to encode every bit in my data set in the form of byte with a bit of data and the other zeros. This means that, for a set of data from 256 MB, I would need 8 times more memory 2048b. I understand that there are a total of 2 GB of RAM on the PXI-6562. Is this all addressable RAM in series? I can write the data of all the 2 GB of RAM for say 8 i/o ports?

    gtg811q

    With the PXI-6562 even if you want to only output a channel you must always write in a format of U8. So, as you describe you that a single bit, worries you, and you will need to set to 0 for the rest. This means that all data that you generate will be the value of 256 MB of data, because the smallest unit you can write with the HSDIO driver is the U8.

    Now in regards to moving data on the two edges of both sides of the sample clock, this is called Double flow of data and is available with our devices OR 656 X and 6547 and 6548 devices. We have a developer area which details the DDR option more.

    Advanced features of NOR-HSDIO: Double data rate

    http://zone.NI.com/DevZone/CDA/tut/p/ID/6718

    In reference to the memory of the generation, the width of the data to the memory of the generation is not configurable by the user. This means that if you have the 128 MB / channel option your total memory available per channel is 512 Mbit/channel. Because the width of the generation of data is set to 1 byte, and you get 4 times the memory per channel mode DDR with the 6562. The KB below explains the behavior. Look under the section 'Generation '.

    Width of HSDIO and allowance data memory:

    http://digital.NI.com/public.nsf/allkb/E5170A54988EF81A8625725A006103BB?OpenDocument

    So, in summary, the total of 2 GB memory won't be available for a single channel, but you have a total of 256 MB/channel available for each channel. Since you are really interested in only one channel you will be able to write data from 256 MB to you. As you would put all your data on the memory of the card you have to the flow of the disc on your generator HSDIO card. To do this, we have some examples:

    NOR-HSDIO Stream from disk (generation) using Win32 IO file:

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/5270

    However, there will be a bottle neck on your PXI backplane data, because the basket max transfer rate will be around 100-110 MB/s you will not be able to cope with your generation session. Since you will write in U8s each sample is 1 byte, which means that the best you can hope to stream would be around 100 MHz or more.

    We have not the cards LVDS SMU (PXI Expresss) which would allow you to have a superior data through-put, but if you do not necessarily need the LVDS, we have other options. I'm guessing you need LVDS or you would not the 6562.

    The other option is to write you data in parallel in the 8-bit generation DDR and then use an external serializer for an 8 to 1, then you would be able to use all of the available memory and you would probably be able to fit all your data on the memory of the card and you do not have to stream from the disc. This external serializer allows you to put your first data point on channel 0, second data point on channel 1 and one until you loop around back and have your second sample generated between the way 0 be your 8th overall your waveform data point.

    I hope this helps and let me know if you have follow-up questions. Thank you!

  • Dear gurus: help with options for upgrading memory on the DV7-1235dx

    I recently bought a used DV7-1235dx and that you want to update the 8 GB RAM, but I'm having a hard time figuring exactly what memory modules are the best for this problem (in a sense general - I don't want to say the brand, well that thoughts on that are welcome, too). I have Windows 7 64 bit. Can someone point me in the right direction?

    Hello:

    I suggest that you run the tool free to advise on the Crucial.com memory and it will tell you what memory you need to buy for your PC:

    http://www.crucial.com/?CPE=pd_msn_us & ef_id=k7hN@oYZUgUAAMO8:20110616224741:s

    From what I could find on my own, I think you would need to PC2-6400 for your machine, but leave the scanner tool do its thing to confirm.

    I've always bought Crucial memory, but for a 4 GB chip, it's quite expensive.

    So, I found that the Patriot memory is a lot cheaper and it works great! I put the chip 2 x 4 GB Patriot in my HP Elitebook 6930p and chips Patriot 2 x 4 GB in HP Elitebook son 6910p.

    I just bought a brand new HP Elite 8200 CMT. It came with 4 GB memory ddr3. I bought a chip of Patriot 4 GB and it works fine. Because the chip worked, I just ordered two other max out this new box.

    Here is the link to the place, I had my Patriot laptop memory if the crucial scanner confirms that this is what you need. You can also read all the comments of consumers who bought the memory.

  • Problems upgrade memory on the Satellite L30-134

    I just bought 2 x 1 GB memory for my L30-134 PC4200 and installed that they work fine in the BIOS, see and read as they should do, but when windows starts up it will crash with the two modules are installed, don't ever get to the screen with the loading bar crossing and then I get the blue screen.

    I forgot to take note of the error code, I'm afraid... (Silly I know). If I remove one of the modules and module installation original 512 with just 1 the 1 GB ones that it works perfectly. BIOS has been updated to the latest version 3.10, and again, I get the same problem...
    because everything looks good go in the BIOS I think that its more likely to be a software problem (windows) any maybe some damage data in the registry or maybe a virus... anyone have any ideas?

    In addition, the laptop is actually my step son and he really wants to have the CPU improved Celeron 410 to one that is a little faster. When we look at first in this we was told that several processors are compatible (although not really worth the hassle of installation) they were cel m 450 2 GHz, dual core t2060 and t2080 pent, as well as the core duo t2250, so he bought the t2250 and it wouldn't surprise, or should I say it power on with no display and the stopcock and just epeated cycle. So didn't take is not a genius to establish it was not compat...

    I know the t2080 are used in of the L30 and 1.73 533 FSB with 1 MB L2 cache-65nm and do walk. The t2250 is identical apart from the L2 cache is 2 MB and deepening varies from c to MB depends on when you bought it... because oe it already has the CPU it will sell and use the money to purchase one that will work. If anyone has any info that could help to ensure that it doesn't end up going round in circles I would really appreciate it...

    Oh and just to make laugh you all he was member of staff line Toshiba tech that had told him that the CPU would not work and that the L30 managed to take 2 x 1 GB memory and not once mentioned that there may be problems with two updates...
    Issues such as neither soddin work... lmao
