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.

    DEll Inspiron 660s, system shows 8GB, can this be increased?
    Thanks for your help.

  7. Miloš

    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.

    Hello dear techie
    I have an acer aspire 7736g with a factory fitted 4gb of Ram, and it slowed down a bit after windows 7 got upgraded to a windows 10 pro. Now matter where I go to research, the status is this…the Ram supported is a max of 4gb.
    I would like to salvage this machine because it still works and it has a big wide 17 inch screen for a laptop.

    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.

  32. 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,

  33. 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.

  44. 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?

    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?

  52. 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 ??

      Or do I need to upgrade the BIOS?? And how do I do it

  54. 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.

    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
