If memtest86+ is consistently reporting a few addresses, then you can
use the badram kernel patch:

http://rick.vanrein.org/linux/badram/

I had some very slight stability issues with my machine after I build
it, and memtest86+ reported one memory failure after I ran it for a
while. The problem turned out to be that my BIOS was, for some reason,
setting the memory timing (CAS/RAS/etc. -- I don't remember which) more
aggressively than the values at which the RAM was specced to operate.
So, if memtest86+ seems to be reporting random, sporadic failures, you
might try checking and increasing your memory timings.
