Re: [gentoo-user] RAM upgrade, kernel and swap

Ahh, but it won't last...

$ free
                          total       used       free     shared   
buffers     cached
Mem:       2059824    2044512      15312          0      37636      50868
-/+ buffers/cache:      1956008     103816
Swap:      4289308    1229024    3060284

Now this I can live with...

$ free
                        total       used       free     shared   
buffers     cached
Mem:       3629832    3499156   130676         0      56644    3070796
-/+ buffers/cache:      371716    3258116
Swap:            0          0          0

Unfortunately that machine is 32bit and thus only supports ~3.6GB of the
4GB of RAM. :-(
