    What is the max RAM Linux will manage, please?

    Locked

    by boxfiddler ·

    I’m looking at some ASUS boards that max out at 8G. I want to run Ubuntu 7.1, with Vista and Office 07 in a VM. If I max out an 8G board, I can easily give the VM 4 which Vista seems to like.

    So, can Ubuntu manage that much RAM?

    Feel free to give me heck if this is a goofy question. 😀

      64Bit?

      I think if you go 64Bit CPU you can use the 8GB. However, my understanding is 4GB is your max on a 32Bit platform. It’s been a while since I was involved in hardware/ servers though. 🙂
      Did you try the trusty Google?

        Hard to get an answer to the second question in newbie terms.

        Thanks. Hmmm… I do have a copy of 64 bit some flavor or another Linux.

          Is your proc 64 bit?
          May help with the OS. 😉

          Edited to add: I believe if you have 64bit Ubuntu it can handle 32GB of RAM with PAE. I am pretty sure 32 bit has the same 4GB limitation as 32 bit Vista.

          Probably go 64 bit, but just starting the research. Finally. I’ve been talking about it for several months.

          Not looking forward to the Vista bit.

          Go with the 64 bit

          32 bit will only handle 4 GB, 2^32 = 4 294 967 296.

          Hence 4GB is the maxium amout of memory able to be addressed.

      something to think about for linux capabilities:
      Supercomputers have a linux option for operating system, with ram in excess of Terabytes, cpus into the hundreds.

      there isn’t any combination of ram / cpu for home systems that will exceed what Linux can handle.
