Hi, thanks Strike, not sure if i understnd the output though. I've got to boxes, one with 64M that gives the following reading:

free -mt
total used free shared buffers cached
Mem: 249 131 118 0 63 30
-/+ buffers/cache: 37 212
Swap: 188 0 188
Total: 438 131 306

And one with 256 which gives:

free -mt
total used free shared buffers cached
Mem: 241 234 7 0 50 156
-/+ buffers/cache: 28 213
Swap: 1027 0 1027
Total: 1269 234 1034

Looks to me from the top row that the first box has more ram than the second and neither are reporting correctly. How am I supposed to read this?

Looks like both boxes have about the same amount of RAM to me ... the first number in the first row is the number of MB of RAM you have (about, give or take some room for the kernel).

You can also do cat /proc/meminfo which gives you the information in a nice formatted list.
