5. If the system fails to post remove the last DIMM installed and set aside, continue from the last DIMM slot and install another stick. (repeat with any other failed DIMMs)

6. If multiple sticks fail in the same DIMM slot install a confirmed working DIMM and verify if the slot is bad. (Make note of defective slot using DIMM guide DIMM_D1, etc.)
