Looking at the dmicode output it seems that we have 8GB memory. May be I am reading the output wrong (it is attached). How much memory is supported by 32-bit RHEL3 smp kernel btw? thanks Nilesh On 4/27/07, Herta Van den Eynde <herta.vandeneynde@xxxxxxxxx> wrote:
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.
