    Question GRUB_BADRAM , Ubuntu 12.04

    I've used memtest to find a bad byte of ram (12 digit hex address around 8100 th MB). I then added that address to /etc/default/grub 's GRUB_BADRAM section. I've uncommented GRUB_BADRAM and then run update-grub. It updated /boot/grub/grub.cfg and I can see the badram entry there. But it doesn't seem to take effect, my box still crashes due to the bad ram byte.

    I've noted GRUB_BADRAM examples are all 8 hex digits but memtest reported the problem using 12 hex digits. How many digits should I use for GRUB_BADRAM ? Any other ideas of what am I doing wrong?

    Thanks

    Why don't you get another stick of ram?

    Well, I don't mind loosing 1 byte out of 8GB

    replacing the RAM is the plan B, but badram seems to offer a better alternative that buying and replacing hardware.

    Anyone, knows any more details?

    this is the entry at /boot/grub/grub.cfg :

    badram 0x00002089d2698

    it doesn't work though.
