Available memory on Raspberry Pi 2 (missing 240 MB)

Question

I just installed Raspbian (2015-01-31) on my brand new Raspberry Pi 2 with 1GB memory.

But I'm puzzled when I run top I only get: KiB Mem: 762384 total.

I've tried to set gpu_mem=16 in config.txt but the result is the same.

Can anyone tell me why I cannot use the total of 1024 MB ram?

If you do a sudo rpi-update that will probably give you back the missing memory.

The current arrangement is a temporary fix to allow sonic pi (and possibly unknown other software) to work properly.

You were perfectly right. I was using the kernel with the sonic pi fix. After the rpi-update i had all my memory available. Thank you for your answer.
