Raspberry Pi "B model" missing memory

Former Member
Former Member over 13 years ago

I just got my Raspberry Pi Model B 2 days ago and it seems a bit sluggish but continued to play with the board, was able to load debian. I was playing in the terminal loading updates and new packages and was looking to see my free space, I have a 32GB Class 4 SanDisk, and also looked at my memory and the system is only registering a total 128mb ram (free -m and cat /proc/meminfo). Has anyone else run into this issue?

    Ed,

      The ram is shared between the CPU and the GPU, so you probably

    have 128MB allocated to each.  This is controlled by the start.elf file

    which is loaded at boot time.  There should be 3 different start.elf files

    available in /boot, with different amounts of CPU ram.  Copy the one

    you want to /boot/start.elf.

      The most ram you can allocate to the CPU is 224MB, but you can't

    play 1080p video with that allocation.

      Dom has said he expects to allow the allocation to be dynamically

    resized, which would be much more convenient.  Latest news on that

    is here:

    which refers to Dom's March 12 comment in this thread:
