  • Ram limit on OSX??

    Hey Guys..

    I just read this on the recording forum

    Correct me if I'm wrong but XP can only allocate 2 g of memory to any app so more than that may not help you much depending on the software you are trying to run. I found this out after putting 4 g in mine.



    Is there any limit in MacOsx??


    Regards.

    From the Memory Manager Guide:

    In Mac OS X, each process has its own sparse 32-bit or 64-bit virtual address space. For 32-bit processes, each process has an address space that can grow dynamically up to a limit of four gigabytes. For 64-bit processes, the address space can grow dynamically up to a limit of approximately 18 exabytes.


    An exabyte is 2 to the 60th, or 1,152,921,504,606,846,976 bytes.

      Ah.. So basically the 32bit users with 32 bit os's get 4gb's and the 64bit users get more than they ever need?

      Thx!

        I think the practical limit is much less than that. I can't recall the thread, but there was some discussion from Logic users that they couldn't get LP7.1 under Tiger to utilize more than 3GB or so...

          This is going to be a little speculative since I do not know exactly how Logic reservers memory.

          Your hardware in most cases will limit the amount of RAMyour computer can use.

          It is true that the amount of memory a 64bit processor can address is 18 exabytes. However, my G5 will only allow 8GB but the new G5 will take 16GB.

          Now, if Logic runs like most other OS X apps memory is dynamically assigned to the application based on need. The more plugins you use, the more RAM Logic will eat.

          What Symbiotic says may be a limit with the application, I am not sure. However, OS X really depends on what your hardware will allow.

          I currenlt have 3GB installed and do not often max it out, but it has happened once or twice.

            Thanks for all the information then.

              Mispellings and all. I know it is a lot of RAM, but I am a huge multitasker. I generally keep open tons of apps.
