Hello please help me ?

My machine has 128 MB of RAM. However, Linux only sees 64 MB of it. What is going on, and how can I fix it?



Thanks for the your time!

What command are you using to determine that?
dmesg | grep memory ?

On most systems, the reason is that the BIOS has a limit of how much memory it will tell the operating system is present in the machine, even though the motherboard can have more.
Common limits seen with this problem are 16M, 32M, 64M, and 128M. To get around this, we need to explicitly specify the amount of memory to the kernel at boot time via the mem=<actual_memory_goes_here> flag.

you can get more information from this link . this will help you to resolve your problem

if you have 2 64MB dimms then one of them could be completely broken, ie, enough so the motherboard doesnt even know its there. does the bios boot screen show 128 MB of ram?

how many RAM in your computer.

if you are using the two rams and both the rams are at different sizes and frequencies than only one ram is shown in the computer as the the highest one.

may be one of the ram has been damaged.
