that i have a error in the RAM my question is : is there a way
to stop the system from using that block of memory that gone bad

question add comment  2 Answers  The only real solution is to
replace it. If it is under warranty (as it should be), you
should be able to replace it for almost free (may need to pay
shipping), by getting an RMA from the manufacturer of it. You'll
have to contact their support and do that.  Or you can use the
opportunity to upgrade to better quality, faster, or more RAM,
if your system isn't maxed out already in that respect.
share|improve this answer add comment  I know grub has
configuration options for bad ram, take a look at
/etc/default/grub. However you might want to consult grubs
documentation as this might only apply on grub, and not on the
booting kernel.  share|improve this answer add com
