8GB memory not being seen in 64 bit ubuntu
 
I have 8GB installed in my machine. It sees it on boot and post shows 8192. I
have the 64bit kernel installed but ubuntu only recognizes 3.2GB.

Free:
free
total used free shared buffers cached
Mem: 3347076 1517968 1829108 0 25616 549916

uname -a
Linux takiyok 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64
GNU/Linux

System > Administer > System Monitor
Also reports:
Release 8.10 (intrepid)
Kernel Linux 2.6.27-11-generic

Memory: 3.2 GiB

Any help to enable the full 8gb would be appreciated

I have the same issue. It seems the motherboard doesn't support more
that 3.2 G and if not then i have been told that the rest of the
memory has been reseved by video memory which I have
nt seen any solution yet. I am using 3.2G only.. damn :(

Err, video might account for 256 to 512MB of missing memory, but there
is something very wrong when an 8GB is only reporting 3gb. Sorry I
can't offer good suggestions on where to look.. Bios settings?

Have you check your BIOS that states there are 8GB installed on your motherboard?
Could you specify your motherboard model and brand?As Rashkae stated video might account up to 1GB at top in certain cases but not 5GBs, so maybe you are running memory modules that aren't supported in your mainboard config or perhaps faulty ones.

Does it show if you boot something else like MS windows? If not maybe
the ram is not installed correctly. I have done that myself. I just
did not seat it all the way.
