Apakah mesinnya 32bit?

Klo benar...silahkan install kernel pae untuk bisa menggunakan seluruh
memory yang ada (hingga 64GB), karena 32 bit punya keterbatasan memory
support hanya sampai 4GB.

*"kernel-PAE* (x86-only): Contains a kernel with support for 64GB of memory
on x86 systems through Physical Address Extensions (PAE). Only x86 CPUs that
support PAE can run this kernel. This kernel is provided because x86 systems
can't address more than 4GB of memory without PAE extensions."
