Description
Disclaimer: Opening and examining cards and moving DIMMs will not void warranty when conforming with the instructions of this technical instruction.

Instead of correctly populating DIMMs in pairs starting from white DIMM slots furthermost from the CPU (DIMM 6 and 7), DIMM pairs were incorrectly populated in manufacturing starting from black DIMM slots closest to the CPU (DIMM 0 and 1).  Incorrectly populated DIMMs have not been verified to work stably by Engineering and should be avoided.

Steps to Follow
Affected part number: All x4600(M2) 8xDIMM CPU Book Configurations.
Serial Number range: Contact Sun support for more information.

Symptom:

Systems may experience intermittent power downs or panics when DIMMs are installed incorrectly.

Corrective Action:

Ensure all CPU Books have DIMMs populated in pairs starting from white DIMM pair furthermost from CPU.
