Upgrade memory (4157) ThinkStation S20

Hi, I'm trying to upgrade memory on my S20. I found this document of 2009 (http://www-01.ibm.com/common/ssi/rep_ca/4/872/ENUSAG09-0134/ENUSAG09-0134.PDF) saying that S20 supports up to 48 GB. I bought 6 * 8GB ECC UDIMM and they work very well, but 48GB wasn't enough to maintain my heavy simulation data. S20 does support 96GB? According to the program dmidecode (Linux utility), my computer supports up to 192 GB, but max memory also depends on the motherboard, BIOS, etc. The official max memory may still be 48 GB, but in terms of architecture, he would support 96 GB or more?

Single 16 GB ECC UDIMM seems very rare, but I found this (http://www.memoryamerica.com/00d4964-00d4966.html) product at a reasonable price. 6 of these modules of memory would work with S20? Or maybe, it is still a good time to invest nearly $600 on DDR3 memory for a machine at age 7?

Thank you.


Welcome to the forum

Looking at the number of IBM FRU in this list, the memory that you have accessed is a RDIMMS, not an ECC UDIMM. RDIMMs do not work in the S20. Unfortunately, you are limited to 6 x 8 GB UDIMM depending on availability of the size. Even if the series E5-1600 processors support more than 300 GB, I'm not aware of a real 16 GB DDR3 ECC UDIMM in the wild.

Given the cost, I recommend personally put that money toward a new system or even a refurb of the Lenovo decision-making. http://outlet.lenovo.com/outlet_us/workstations/#facet-1=1, 2,3,4. Major drawbacks only in a system is that you are limited to what is available and they come with a 1 year warranty. Retail systems have a term of 3 years and can be extended to 4 or 5.

Assuming that you land in a P500/700/900 or later version, you can find 6 or 8 x 16 GB DDR4 memory for about $350 ~ 600 depending on where you look. The smallest series P (P310/320/410) have 4 total DIMM connectors and limit your options.

  • ThinkStation s20 starting problems

    Hello to one who reads this,

    Thanks for the time to stop talking and to read my question.


    I was using my thinkstation s20 for a year now and have not had any problems for a long time. I updated to Windows 10 and upgraded to a Gtx 1080. The thinkstation took all without problem and both of these improvements/changes have made about 6 months before this Post. Yesterday I suddenly started having problems with the performance of the machines.

    The system crashed while I was doing some points of reference. I rebooted the system, and everything was going well until it finally crashed again. Today, I started the machines and nothing works. It is stuck at the start screen and I can't see is the lenovo thinkstation Logo on my screen. Sometimes, but very rarely the product of the system, but all he said then is that no operating system is found. Some odd things also came to my attention: when I started the PC before Fans would turn quickly and then slowly down to a normal speed (Im almost certain that those who were Fans of the Gpu only). Second, the events began occurring after I have updated to the latest drivers for the Gpu

    Thank you for taking the time to read

    Any help is appreciated

So I just reinstall Windows from a disk to a new hard disk, I always had on an old pc and put it in the machines. If everything is working again now. Thanks again for your quick response!

  • Upgrade memory on an all in a single LX830

    I may upgrade the 4 GB provided to meet the requirements of the program. Additional memory needs to be installed in pairs? The existing 4 GB occupies a dwelling, can I mount 8 GB in another location or it will be incompatible?

    Well, mainly upgrade memory depends on the support of the chipset/CPU.

    Not quite sure what computer Toshiba LX830 do you have exactly but as far as I know the L830 all in one units would support up to 16 GB of RAM.

    A property used by a 4 GB RAM module and housing is free.
    This is why it must be able to use another additional module of 8 GB RAM.

    But of course, another module of 8 GB RAM should be compatible with the current 4 GB of RAM.
    Otherwise, you will get some compatibility issues

  • Upgrade memory on NB300-108

    Looking to upgrade the RAM to 2 GB on my NB300-108

    Have you looked at the website of Toshiba and the cost, but there seems to be a plethora of alternative sites with upgrades memory compatible when I put in the part number.

    Would like to receive experiences in the forum about alternatives etc.

    Thank you


    The laptop supports DDR2 800 MHz SO-DIMM or PC2-5300 (DDR2 667 Mhz) modules.
    These modules are provided by different companies.
    There are good quality modules and less quality modules

    Of course, you can choose and buy the cheapest, but in this case, you use the risk of compatibility problems.

    I made good experiences with RAM from Kingston. These are of good quality and not too expensive modules

  • 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.

  • Question about upgrading memory Satellite M55-S1001

    can you please recommend what to do? I want to make my satellite m55-s1001 run faster please let me know, what do you recommend: 512 MB or 1 GB of memory? I'm not familiar with updates so please help!


    First of all, if you want to go for fastest laptop, you should start with simple things.
    Try to defragment the disk, turn off the background process is not necessary, etc.
    Upgrade memory will the powerful laptop and of course a lot more quickly.

    To my knowledge the Satellite M55 should support the bars of memory 2 x 1024MB, and I also recommend the use of 1024MB instead of 512 MB module.

    Hi Ben

    Maybe you used the memory modules bad.
    As far as I know that you can upgrade memory for max 192 MB
    The 64 MB has been installed in an internal memory and cannot be deleted.

    I found these compatible modules:
    PA3003U - 1 M 03 32 MB
    PS3004U - 1 M 06 64 MB
    PS3005U - 1 M 12 128 MB

    It is rather urgent and would like a quick answer.

    Thanks in advance

    Hi mate.

    As far as I know your laptop supports two memory locations.
    They must be placed at the bottom of the unit.
    If you n t know how to change this then I recommend consulted the user manual!
    The manual can be downloaded from the Toshiba European page.
    I think that the laptop can be upgraded to 2 GB of RAM. So, you can use 1 GB of RAM in one slot.

    PS: you must use the RAM DDR2 PC2-4200 memory - 200pin modules

  • HP ENVY Sleekbook 4-1000en: upgrading memory on ENVY 4-1000en


    Since I have some basic computer knowledge, but I want to be sure before you go for it, I need your advice.

    I have a HP ENVY Sleekbook 4-1000en and I have recently upgraded to HDD and the OS.

    I think the upgrade of RAM have, as far as I know that you need 2 memories of the same type, so I guess I can't buy an another 4 GB right?

    Do I need 2 x 4 GB of DDR3 memory, of the same type to make it work? For example they would work very well

    http://www.corsair.com/en/vengeance-8gb-high-performance-sodimm-memory-upgrade-kit-cmsx8gx3m2a1600c9 ?

    Finally the upgrade memory requires any other configuration after plugin in? Is a format for example?

    Thanks for your time.


    The following link shows the specifications of your computer:


    It has 4 GB of RAM now. The question is 4 GB in a dwelling or in the two slots (2 + 2).

    b in the case of a home, you can just buy another 4GB with SAME part/characteristics of the EXISTING RAM and install in the second slot.

    (b) if in 2 slots (IE 2 + 2), then throw them both and buy 2 new sticks 4 GB each. Agin use even care.

    You don't need to format RAM. Moreover, we have only to format HDD/SSD but not RAM. And Yes, push in the two slots must be same same specs even marks to be able to get all the benefits.

    Kind regards.

  • Satellite Pro 2100 - upgrade - upgrade memory RAM

    Hello together!

    For your information:

    Upgrade memory today to 2 Toshiba Satellite Pro 2100 (1.9 GH, 256 MB DDR - RAM initially), both up to 1 GB, all fine and no problems.

    Wanted to just end rumors "only 512 MB all together" or even less.

    If you are looking for, don't forget to think of the specifications:

    DDR-266 (PC2100)
    200 PINS
    2.5 CL

    concerning the frequency of the RAM, building shape etc.



    P.S.: Don't think that a debate is necessary, thread could be closed...

    According to the specifications of the computer laptop Satellite Pro has two memory slots and can be upgraded up to 1 GB. It is very useful to have confirmation on the RAM upgrade for this model of laptop old but still good.

    Good day.

  • Portege 3500 - upgrade memory

    Necessary upgrade memory for a p3500. 'Expert' advised two sticks of 512 MB PC133, but on opening the rear of the location that a laptop computer and on the insertion of the new RAM it gives an error code beep. Is there than a single slot? and if so what maximum capacity and what type of RAM will it take?

    Hi Jeffrey,.

    As far as I know the 3500 Series provided with a removable module of RAM of 128 MB, 256 MB or 512 MB depending on what model and specifications you purchased. There is one other remaining slot for expansion purposes.

    The total support for the 3500 Series RAM is 2 GB and the type of RAM should be SODIMM PC133 144 pins.

    It is important that you match the RAM modules that your RAM module existing (one removable) is of the same type you new RAM module. Of course, you can always delete the original from the RAM and insert two new modules of RAM instead.

    Please check the following URL for more information on the available RAM module type.



  • upgrade memory in a Portege 3410ct

    I tried installing memory of 128 MB PA3034u 3410ct, but on commissioning a message comes up saying that the ACPI BIOS is not fully compliant with the ACPI specification.
    I downloaded the latest BIOS setings but makes no difference. Will not start just yet. Clues as to correct the problem, other that not upgrading memory.


    This problem may occur if you add the memory (RAM) to the computer when it is in hibernation.

    When the computer comes out of hibernation mode and load the file Hiberfil.sys, Microsoft Windows detects the change in the State of the memory, and then you receive the error message.

    To resolve this issue, restart your computer.

    If the problem persists, start the computer by using an emergency boot disk, and then delete the Hiberfil.sys file.

    Good bye

  • Firefox 4 beta too slow / crashing after upgrade memory?


    my beta firefox started crashing my whole system yesterday and only noticeable change I did was upgrade memory of 3 to 4 GB of RAM...

    I tested my system widely and it works very well until firefox is started, after that, the system started crashing and takes forever to be reactive. I uninstalled and reinstalled firefox, tried running without addons, I tried to close all the tabs and all Eske I remembered... still no luck.

    I am desperate because I really wanted to keep this beta on my computer, and cuz is a new facility, I can not install firefox 3.6 on side by side, I only have an option 'upgrade' on the installation wizard...

    What can I do to fix this?

    Thanks in advance!

    The steps to troubleshoot and diagnose problems of Firefox would say you always try in questions to troubleshoot Firefox in Safe Mode of course some additional software may conflict, it is even more likely if you are using a beta version of firefox and probably the beta or alpha some of the addons or plugins.
