Recycle faulty RAM sticks in your Linux box
I’ve built a Linux box from my spare parts bin, but unfortunately two out of the three 128MB RAM sticks I have are faulty. Fortunately, an enterprising Linux hacker by the name of Rick van Rein has built a kernel patch which allows Linux users to mark faulty areas of RAM so that they are never accessed, similar to the way that bad sectors on hard drives can be marked unusable. You can read more at the BadRAM site.
Unfortunately, enabling BadRAM support requires recompiling the kernel, which is a daunting procedure for non-technical users. However, Ubuntu users might find this thread helpful.
