I just installed Ubuntu Server 11.10 64bit and when I execute free -m it only shows a total of 24094.
This is a fairly new build and I was able to see all 32GB on Solaris 11.
total used free shared buffers cached
Mem: 24094 582 23511 0 11 195
-/+ buffers/cache: 375 23718
Swap: 24571 0 24571
I am running a Gigabyte 990FXA-UD5 mobo with the AMD 8150 Black Edition proc.
Any input is appreciated.
** Update **
dmidecode is showing the DIMM in the first slot as only 4096 MB
