Product Image Ramjet now offers the ability to upgrade the new aluminum MacBook and the black bezel MacBook Pro to 6GB via one 4GB SO-DIMM module (US$599) and one 2GB module ($75) to reach the system maximum of 6GB.

According to the company the modules are fully compatible with the latest Apple firmware, and are SPD configured for the MacBook and MacBook Pro.

The newest MacBook and MacBook Pro with the black bezel surrounding the monitor, require DDR3-1066 memory (also called PC3-8500).

Ramjet uses a non-stacked module for the 2GB and 4GB module for the MacBook. The cheaper stacked IC variety of 2GB and 4GB SO-DIMM run hotter and draw more power, which hurts performance and decreases battery life.

Although the 4 gigger is a little expensive, if you need the RAM, you need the RAM. The Ramjet 4GB modules are shipping now and come with a lifetime warranty.

  • The problem is that at least 2GB ....

    ... will be substantially slowwer. DDR memory alternates devices when storing data to allow for address lines to stabilize. There is no second memory location for half of the $GB device.

  • Dell E series laptop can run 8GB already

    Only 6GB and no Upgrades on CPU...

    • oh come on.

      have you EVER upgraded the CPU in a laptop? please.
      lostarchitect
      • yes

        yep, I have....

        But the MacBook line is so much better right now, I don't really
        give a crap about upgradable CPUs or GPUs

        • Yes,

          My M1330 was upgraded from t5250 to t8100. No BIOS needed, and 4GB ram that is much cheaper than Mac modules. I have Linux and Windows 2008 64. I donot have shell extra momey for another laptop.

  • Can you confirm...

    ...that the 6GB limit only applies when running OSX and that if you're running Vista it'll recognise 8GB?

    • If its a hardware limitation it won't matter.

      My Dell laptop I got almost 2 years ago can only handle 2 GB sadly. At least that is what I've been told.
      logicearth@...
  • Well...

    ..that chipset should handle 8GB so I'm not sure why the limit is 6GB.

    Any comments?

  • RE: 6GB of RAM possible in new MacBook and MBP

    Yes, in my PowerBook 1400 which had the CPU in daughtercard which can swapped out for slight faster version of the same CPU.

    However this is very uncommon since the sockets for this is relatively large and takes limited space in a laptop.

  • Well there are several things here.

    Yes you have an chipset that can handle 8GB of RAM but the manufacture, in this case Apple, can limit this by either firmware, special chipset version, or operating system.
    I can't tell what is the limiting mechanism so one can attempt (and void an warranty) to bypass this limitation. If is special chipset version then you have no choice, except to replace the CPU or other part that is limiting this in the hardware. If it is firmware then you can attempt to bypass this by using a hack. I sincerely doubt it is in the OS but not impossible but least like, but most easy to bypass with voiding warranty.

    • So, since as far as I'm aware...

      ...Vista 64 will recognise and support 8GB using that chipset does that means the fault is with OSX or the mainboard drivers?

      • Might be a heat issue.

        Ever grab onto a memory dimm off a system thats been
        running? Sucker gets HOT. Now I wonder if denser chip sets
        tend to get hotter still? Those systems are pretty tight and I
        suspect heat is an issue for everything involved.

  • This article is VERY WRONG!

    I ordered the very first 17" unibody MBP in Mar.2009, and it came with a (then very expensive GBP1200!) option to have 8GB (2x4GB) on the custom builds.

    While I didn't shell-out for one then, a friend with similar machine did, and he got the *FULL* 8GB of memory out of them then. Just as I get out of mine NOW with third party (18 months later just GBP80!) 2x4GB RAM modules.

    So this article is completely wrong and misleading.
