"This paper studied the incidence and characteristics of
DRAM errors in a large fleet of commodity servers. Our
study is based on data collected over more than 2 years and
covers DIMMs of multiple vendors, generations, technolo-
gies, and capacities. All DIMMs were equipped with error
correcting logic (ECC) to correct at least single bit errors"
from conclusion 1.
"The conclusion we draw is that error correcting codes are
crucial for reducing the large number of memory errors to
a manageable number of uncorrectable errors. In fact, we
found that platforms with more powerful error codes (chip-
kill versus SECDED) were able to reduce uncorrectable er-
ror rates by a factor of 4–10 over the less powerful codes."
