Running Ubuntu Server 11.04. I've got a new Dell Precision T7500 workstation loaded up with 12x8GB DIMMs and the BIOS shows 96GB but checking /proc/meminfo gives:
cat /proc/meminfo | grep MemTotal MemTotal: 82650584 kB
and free gives:
free -m total used free shared buffers cached Mem: 80713 5254 75459 0 89 3304 -/+ buffers/cache: 1860 78852 Swap: 95365 2 95363
The Win7 install that it came with showed 96GB with 80 GB usable, as well.
Does anybody know what's going on?
