This Dell DM4700 came with 2-256 mb strips, some time ago I added 2-1 gb strips for a total of 2.5 gb. This morning I replaced the 256 mb strips with 2-2 gb for a total of 6. The bios setup screen shows 6 gb but apparently Linux is only using half that amount, not much of an improvement!: [bobg@box6 ~]$ free -m total used free shared buffers cached Mem: 3022 719 2303 0 31 265 -/+ buffers/cache: 422 2600 Swap: 4575 0 4575 This is an up to date F-15 32 bit configured as I want it.

If so perhaps I could upgrade the present install to 64 and keep my configuration or do I have to bite the bullet and do a new install.
