again .. that's not what i said ..
the point i've been tring to say .. one MUST figure out "exactly"
where the bad data or errors or crashes are coming from
it will usually be bad ("cheap") parts or operator error
or simple "slapped" together boxes

that's what i was saying... but you do a better job
even if one uses ecc... ecc can only fix certain errors,
and non-correctable errors are flagged and not fixed
( burst errors are hard to fix )
and people that use ecc memory ... usually have higher-end motherboards
and more memory in the system vs the $50 motherboard+cpu combo (disasters)
from fries ( a local pc store )
