Re: Physical memory present on a machine



Hi Nilesh,

The Red Hat AS3 smp kernel which you are running is quite capable of
seeing 8 GB memory if it's there.  Looks to me you only have 4.

If dmidecode looks too intimidating, try "dmidecode -t memory | grep
Size" and add up the sizes.

Kind regards,

Herta
