      Does pfsense 1.2.3-RC1 support more than 4 gb RAM? I install in a 6gb HP ML350 and only 4GB was detected by pfsense. How change it?

            I do not think it's good idea. You can install as many gigs as you wish but pfSense will not see more than 4 GB.

              32 bit OS's can only address a maximum of 4 gigs of memory.  I've got 4 gigs of memory installed on 1 pfSense box and it ignores the top 512 mbs (needed to re-address video and such).  System runs fine though.

              According to the following thread the 32 bit version apparently works better than the 64 bit version of FreeBSD.

                @TreeTopFlyer:

                32 bit OS's can only address a maximum of 4 gigs of memory.

                This is a common misconception. The way virtual memory works means it's quite logical and feasible to address a far larger memory area than the processor's native address space. You can get up to 64GB of RAM on most Intel CPUs since Pentium Pro.

                But I agree with the rest, I hardly see the point for pfSense. Pull the RAM and use it somewhere it'll do you go, or just pull it period and save a little bit of power.
