      Look in /var/log/dmesg.boot, in the first few lines it prints the amount of memory detected/available/etc.

          What do you see if you run this at the command line:

          sysctl hw.physmem

              Hmm, odd.
              So you originally said you had 2GB but it looks like you have 3GB now, did you add more?

                  Facing the same issue system is showing
                  hw.physmem: 3587276800

                  but still getting the same error. I do upgraded RAM FROM 2GB TO 4GB.

                  any help is highly appreciated.

                    In your case it's highly likely the BIOS is reserving part of your 4GB for something else….
                    If you have a motherboard based graphics card, the BIOS often will share 512MB for graphics.

                    With pfSense, you can safely reduce this in the BIOS to the minimum allowed as the console is text only (no graphics required).

                      Had this same issue. Turns out my solution was to install the 64-bit version. IDK why that made the difference but it did!

                        2gb of DDR1? 64bit system? That must be a really old server .
