Ubuntu 9.04 shows only 988 MB Memory

[Nuxer]

My Ubuntu 9.04 64bit version only shows 988 MB Memory out of 1024. Where is the remaining 36 MB Memory?

Probably bad RAM, or BIOS setting, or shared video RAM ?

----------

BTW for me too it shows only 3.7 GB out of 4 GB real

Ubuntu 8.10 shows 1023 MB memory on this machine. I have a dedicated Nvidia graphics card, so no matter of shared memory. Bios shows full 1024 MB memory.

check in a terminal to verify : " cat /proc/meminfo".BTW ,Are you still on 32-bit Ubuntu Linux?
