To determine the failing DIMM, match the lowest five bits of the failing address in which
the bad data is received to the failing DIMM using the table below.
Failing Address
Lowest Five Bits
0
8
10
18
In the example, the lowest five bits (represented by the last or rightmost character in the
address) in the failing address is 8 (a11848). Therefore, the failing DIMM is DIMM 1.
