Ubuntu – Exclude bad ram bytes


I have 5 bytes (or bits, don't know) of bad Ram. How can I exclude these bytes so my Ubuntu 11.10 don't use them. My PC randomly freez, and when I ran memtest it reported 5 errors.

The only solution that I know of is BadMem (by Rick van Rein), who is able to block bad memory sectors in Linux.

It works by instructing the kernel to lock those memory addresses you specified. This effectively stops Linux from ever addressing those addresses when allocating (and deallocating) memory.

You can read all about at the BadMEM-HOWTO page!
