Huh? The size of RAM is the amount you have plugged into the motherboard.

Do you mean over-clocking the RAM speed? That's usually done through your motherboard's BIOS.

Normally the kernel will detect the amount of memory installed but if you want to specify less memory then you can pass a kernel option in the bootloader or at the boot prompt i.e.
mem=128M

If the operating system is not detecting the full amount of memory (>=1gb) then you might need to recompile the kernel to include high mem support.

Post the distribution / version of linux you are running?

This contains information on the ramdisk settings. not exactly sure what you want to do with it.
