Reasons why the maximum we quote for your system often exceeds the stated maximum of the manufacturer.

The more observant of our customers are very quick to tell us that our stated maximum configuration of their systems doesn’t match the manufacturer’s specified maximum configuration and ask whether we haven’t made a mistake. Our simple answer is NO! We have deliberately increased them. In the following article, we’ll explain how we come to our figures.

Device data meticulously stored since 1998

In order to be able to make an informed statement on the maximum memory capacity of a system, we have maintained an extensive system database, going all the way back to 1998. This contains detailed technical information on the systems available at any given time. Details of every component – from BIOS, CPU, memory socket, graphic board to chipset – are analysed. It is possible for us, even years later, to determine which memory module fits which system.

Why there’s room for more…

The reasons why it is often possible to install far more memory than the original manufacturer intended can be attributed to the following factors:

  • The density of the DRAM components, i.e. the number of bits that can be stored in a given space has dramatically increased. Today, memory offers capacities that would have been unthinkable or unaffordable, even a relatively short time ago. Unfortunately manufacturer’s specifications rarely take future, high density memory components into consideration.
  • Current BIOS versions are updated to take changes in the individual system components into consideration, in order for BIOS to fulfil its duties as the system’s control centre. The most current DRAM generations are supported, allowing them to be integrated into older systems.
  • Artificial limitations can also be unknowingly set by the manufacturer, through introducing errors or by putting too great a focus on other technical details. Limitations can also be deliberate, created by the manufacturer as a marketing strategy, to differentiate various models in the marketplace or, perhaps, because the larger memory modules were not available in large quantities. It is also possible that the pre-installed operating system is unable to address the maximum amount of installable memory. In such cases the system manufacturer may reduce the maximum installable memory, rather than replace the operating system with one, which can cope with a larger memory.

Using our know-how to gain more speed

Few system manufacturers continue to maintain data on their older systems. The manufacturer’s system specifications reflect the upgradability of system components, available at the time of the system release.
Thanks to the meticulously maintained data in the CompuRAM database, we are able to monitor the upward trend of the maximum installable memory and remove some of the limitations set by the manufacturers – to the benefit of our customers.

Customer comments on maximum upgrade:

The "plus" of more RAM than the manufacturer of my NAS says works. So you can assume that the people from Compuram know what they write 😉
The statement of CompuRam that instead of specification in my laptop of 8GB even 16GB would work was correct. Respect ...
...According to the manufacturer, my laptop from Sony can only handle 8GB Ram, but it can handle the 16GB supplied without any problems. I am very satisfied

  4. CJ

    I have a Sony Vaio VGN-SZ120P from 2006 running Windows 10
    Manufacturer says 2GB is max DDR2
    It has 2 slots that can run in duo mode if matched
    Can I run more? That would be amazing

    Also have a Net book 2010 Gateway LT2802u with Windows 10
    with one slot Max 2GB Manufacturer Max
    Can I run more? Double amazing

    I stripped Windows 10 down to the bare minimum, disable WIN Defender
    Combo of several hacks, Ready Boost
    Run Firefox in mobile view with adblocker
    To get usable operating speed
    More RAM would be fantabulous!!

  17. chris brennan

    hi guys – can my dell inspiron 15R N5110 i7 windows 10 pro Bios A11 use your 16gb kit?

    1. CompuRAM Redaktion

      All DELL Inspiron 15R N5110 can use this 16GB-Kit.
      There is never a reason to use an old BIOS if the manufacturer offers a bugfixed and updated version.
      This principle is independent of our upgrades.

    good day sir i just bought 8gb ram but i still not putting it to my acer travelmate b117 already,is it compatible,can i?
    since it has 2gb ram only installed inside,

  20. Tommy

    I have a Toshiba Satellite Pro L450 which came with 2 X 1GB RAM cards installed. I’d like to max out this RAM.
    2GB and (I believe) 4GB cards are available. I’m sure the laptop will accept 2 X 2GB cards. Will it also accept and utilize 2 X 4GB cards, yielding a total of 8GB ??

    I can’t find a straight answer and it appears that Toshiba has been bought out by DynaPro, which offers NO telephone support. (frown)

    Any good response is greatly appreciated.

  21. Dan D


    HP advice that the maximum RAM for HP 470 G7 should be 16 GB. I wonder if it´s possible to gain the amount of RAM over that limit? What should the max RAM it be?

    I have an acer aspire one happy 2 with 2GB DDR 3 ram. Can it be upgraded to 4 gb?


  23. Lester

    Hello CompuRAM,

    My mom has Acer Aspire 5734z-4725 and the manufactured max ram it can have is 4 GB. Since I already have 1 GB in 1 slot, can I add another 4 GB PC3 10600s (same spec, diff GB) on another slot? Will it encounter issue since it already exceeded 5 gb? Also, if I will install Win10 (currently in Win7), can I exceed 4 GB max limit since 4 GB in Win10 will not be enough.

    Thanks in advance,

    Some sources claim that max. possible RAM for this laptop is 3GB while other sources say that max RAM is 4GB.
    Can you confirm which one is true?

  25. Sean Low

    Hi CompuRAM,
    I have an old Lenovo Ideapad U300s which I would like to fix up by adding more RAM. Currently, it has 4GB and Lenovo states that the maximum is 4GB. Can I put in a 8GB RAM or is it limited to 4GB? It only has one slot. Thanks for the advice.

  26. Luis Eduardo

    Hi, I have a Dell Vostro v130 that dell insist in inform that the maximum amount of RAM is 4GB but intel Processor U380M and Intel Chipset HM57 are both compatible with 8Gb of RAM but everytime that i try to upgrade RAM i receive an Blue Screen error on windows…the BIOS recognize the 8GB RAM at 800Mhz.
    I´ve already tried to upgrade using 1 module PC3-10600 and PC312800 and both show me the same error!!
    I need some help because nowadays 4Gb is too low to run W10!!!


    1. CompuRAM Redaktion

      Hello Luis,
      sorry to say this, but your assumption that 8GB will work in your system is not right.
      Dell Vostro V130 only accept 4GB RAM, because only one RAM slot is available.
      You are right, Processor and Chipset would able to adress more RAM, but not more than 4GB per module. So stop wasting your time with further experiments.
      Best regards from CompuRAM

      1. Luis Eduardo

        Many thanks for your quicly answer…
        i forgot that 8Gb could be 2x4Gb :(…. why dell did this???? there is room to another slot memory…
        I upgraded it with a SSD driver and 8Gb of RAM will be perfect to run W10 and keep this machine still working “well” for regular user as my mom! 🙂
        But ok…the SSD itself gave some performance gain…

        Thank you again!

  27. Mark

    I have a PC with this motherboard: Pegatron IPMEL-AE REV 1.02 and I found on the web, that there is maximum RAM size 4GB, which I am using right now. But I would like to upgrade it, so my question is if it could handle e.g. 8GB?
    Please help me.
    Thank you


    Hello I have a Toshiba Qosmio X770-107 and I want to upgrade it’s memory from 8GB to 16GB, I made a research and I’m totally confused, because some say that 8GB is the maximum and others that you can have 16GB (CPU recognized and work properly with all this 16GB). I saw that you offer a 16GB kit for Qosmio and i want to ask if you guarantee that this kit will work for my Qosmio X770-107, and if yes, which is suitable:
    the 1333 kit or the 1600 kit or it doesn’t matter because works with both.
    Thanks in advance.

        Thank you. I am in the USA. I notice your site has many languages and methods of payment. I assume selling and shipping to the USA is not an issue.

        Also my concern with upgrading past the manufacturers recommendation is the if the system will not recognize more than the stated limit. I did read your article. However it is technically possible that the motherboard design does not allow for addressing memory above the stated limit. If the upgrade does not work. What is the warranty and return policy.

        I plan on purchasing, and then running exhaustive system tests for the first 24 hours.

        Thank you very much for your quick reply and assistance.

      2. CompuRAM Redaktion

        I’m sorry, usually we only ship within the EU.

      1. Luke Donnelly

        Is that 1x 16GB or 2x 16GB (total of 32GB) for the Inspiron 5000? I’m guessing the same will go for the Inspiron 14 5000 2-in-1 too, right?

  40. Nigel Sharp

    I have an HP Elitebook mobile workstation 8740w, with quad core. The manual says the max RAM is 16 GB, and I have 4x4GB cards in it now. Could I actually replace one pair of these cards with a pair of 8GB cards and upgrade it to 24GB? If so, would I put the 8GB cards in the 2 main slots or in the 2 auxilliary slots, leaving a pair of 4GB cards in the other slots – or would either of these configurations work OK?

    I’ve been using an older Fujitsu Esprimo V5505 with 2GB RAM. Your website is the only that states that it can take 8GB of RAM, of course if a 64bit OS is installed. Is this laptop the case described in the article (that is, for whatever of above mentioned reasons, it does actually support 8GB instead of 4GB specified by the manufacturer)?

    1. CompuRAM Redaktion

      Hello Milos,
      the system can be equipped with up to 8GB RAM. You can find the right modules for your system here.

      In our blog post “Maximise the maximum” (above) you will find detailed information why sometimes higher capacities than specified by the manufacturer are possible.

    I have DELL G5 5587 with i7-8750H CPU. The Dell says that the maximum RAM for this model is 32GB . I saw in your shop 64GB RAM (2×32) sticks that can be bought for upgrading of some DELL laptops that are the sam generation like mine, but they supports 64GB of ram with only 2 SO-DIMMs. Tell me please, can I upgrade my G5 with 64GB of RAM (2x32GB)?

    Thank you

    My Lenovo ideacentre B300 is using 2GB+2GB ram with 64bit OS. Will it support 4GB+2GB or 4GB+4GB or 8GB?

  74. Max

    Hi I have an Acer Extensa 5630 Laptop. Using the CPU-Z software I am able to see that there is a DDR2 ram. It is PC2-5300 type. However under your search for RAM upgrade it is suggesting PC2-6400 type. I have currently 4 GB RAM (2 x 2GB) installed. Please let me know if the system would be capable of using 8GB if installed?

    1. CompuRAM Redaktion

      Hi Max,
      we recommend you use our own tool RAMinator to analyse your PC. It will directly lead you to the compatible modules for your system within the CompuRAM web shop.
      For your system, there is a maximum of 8GB RAM possible with CompuRAM upgrades.
      Best regards from CompuRAM

    Hi I need your help,
    I have Toshiba Qosmio X500-110 model and the manufacturer stated that the maximum expandability: 8,192 MB The current Ram that I have is 6GB (6,144 (4,096 + 2,048) MB) and the specifications are the followings:
    Samsung 2 Gb (1066MHz) 8500s SODIMM 1.5V
    Samsung 4 Gb (1066MHz) 8500s SODIMM 1.5V
    The processer specifications are :
    Type : Intel® Core™ i7-720QM Processor
    clock speed : 1.60 / 2.80 Turbo GHz
    Front Side Bus : 1333 MHz
    3rd level cache : 6 MB

    Please help me to upgrade it to 16gb if that possible or recommend for me what I can select.

  76. Michael Sonder

    I have an Acer Aspire 6935G with 4GB (2x2GB) 1066 MHz memory installed, as per manufacturer’s specs.

    How on earth did you manage to make it work with 8GB 1333 MHz memory?
    Which specific memory did you use to achieve this?
    Do you have any proof to back your claim?
    Like screenshots from CPU-Z.

    I find it impossible to believe it’s true (although I sincerely hope it is), since in all the forums I’ve checked, max memory anyone achieved to make it work was 6 GB 1066 MHz.

    1. CompuRAM Redaktion

      Hi Michael,

      we can assure you that 8GB will work in your system if you use CompuRAM upgrades.
      As explained in the article above, the maximum RAM information given by the manufacturers is often outdated – however, we consistently update these numbers.
      Regarding the clockspeed, it is always the maximum possible operation mode of a module that is indicated. Please read this blog article for further insights.

      Best regards,

  77. Justin Schelin

    VERY interesting and thanks for all your hard work! I have the same HP Z400 gen.2 (6 DIMM) as another noted in a previous comment/question… in maxing the max RAM to 48Gb, does the system require a BIOS update. If yes, is it a BIOS written/provided by Compuram through purchase of your modules? I have (HP max=24Gb)modules in my eBay cart- ALMOST checked out and decided, thankfully, to research further:} YOU ROCK!!

    1. CompuRAM Redaktion

      Hi Justin,

      it is recommended to update your BIOS to the latest version before upgrading your RAM. These are provided by the system manufacturers.

      Best regards from CompuRAM

  88. WM Mak

    According to QNAP, the maximum supported memory for QNAP NAS TS-253B is 8GB (2 x 4GB).

    If I upgrade it to 16GB (2 x 8GB), can both the hardware and operating system really make use of the memory in excess of 8GB?

    I mean the system may report 16GB was installed, but it may not be able to use the additional memory in excess of 8GB?

  89. JF

    Does Dell E7270’s bios automatically supports newer 2800mhz or 3000mhz sodimms?

    Hello, I have read that my laptop a SONY VAIO VPCF13Z1E/B can utilize 16GB although the manufacturer states 8GB ram max. Since I would like to purchase the kit, I need to be sure that this is possible. Have you tested it on the the specific laptop? I live in Greece, in case that the kit is not installable how can I get a refund?

    Hello Sir How much maximum a ThinkCentre Edge 71 1577 RAM can support?

  96. Fred

    HI, I have a vaio vgn-bx397xp.

    It already works with 2gb RAM 2 gb 2Rx8 PC2-4200S DDR2 533MHz SODIMM.
    But it is not working with both of those memories.

    I would like to know if 4 Gb is really reachable (since on your website you sell 2×2 Gb for this computer), and if it is needed to modify something (hack or any procedure on the bios ?) and if yes, could you give me the exact procedure. Thanks !

      1. Fred

        Yes, I read, but it’s not an OS problem, it’s a BOOT problem (BIOS ?).
        The computer stucks with black screen when putting 2 memories inside. But when using one of them (both works) no problem.

      2. Fred

        Even 2 years after, I’m still waiting for your answer. Won’t buy until I’m sure your memories are working since for me it didn’t worked as I explained (each 2 gb memory is working fine if only one is used). See my previous answer. Thanks.

    1. Piyush Goel

      My laptop is x250 can I upgrade It to 16 GB RAM without any issues ??

  97. Hiren Patel

    Hi is 8GB Module support to IBM Server System x3200 M3 -[7328I6S]- ???

  98. Andrew Burnham

    so just to be sure before I buy this…. you are saying that the dell inspiron 7559 I7 with the nvidia 960m is upgradable to 32 gigs correct? I do a lot of video rendering and a lot of digital art through intensive software suites and am willing to take the plunge into the 32 gig realm ONLY IF it will definitely work in this laptop. Please advise. Thank you.

  99. Rui Vieira

    I’m confused by this phrase on the manual for my supermicro H8QME-2: “Maximum memory: 128 GB DDR2-667/533/400 registered ECC SDRAM (256 GB for 8-way configuration). In a dual-CPU configuration, memory support is halved.”
    I have 4 processor installed. What is the maximum memory allowed? 128GB or 256GB?

    1. Tom Bauer Post author

      we double checked this issue. Maximum memory allowed are 128GB with 4-CPU-configuration. Unfortunatly our configurator showed 32 Slots, instead 16 Slots. With 16 Slots you can reach 128GB – build with 16 pcs 8GB modules.
      many regards
      Tom Bauer

      1. Rui Vieira

        Just one more thing: what exactly is this “256 GB for 8-way configuration”?

      2. Tom Bauer Post author

        8-core configuration is 4 pcs AMD with Dual Core CPU Opteron 8200 series.
        Theoretically can be addressed with this configuration 256GB RAM. Unfortunately, the necessary 16GB DIMM were never developed.
        Since this board has only 16 DIMM slots there are only 128GB maximum RAM.
        many regards
        Tom Bauer
