1. Replace DIMM nn, where nn is the DIMM number.
2. System board.
1. Isolate the failing DIMM.
a. Replace a DIMM in bank with a known good DIMM.
b. Rerun memory diagnostic for the failing bank.
c. If test fails, mark replaced DIMM as good DIMM.
d. If test passes, mark replaced DIMM as bad DIMM.
e. If DIMM tested is bad, replace the bad DIMM.
f. If DIMM tested is good, do not replace it.
2. Repeat steps 1a through 1f with other DIMMs in the failing bank
until the error is corrected.
3. If error is not corrected, replace system board.
