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 On 27/04/07, J.Reykdal <redhat@xxxxxxxxxx> wrote:
