CAUTION: The memory module sockets have gold metal contacts. When upgrading the
memory, it is important to use memory modules with gold metal contacts to prevent corrosion
and/or oxidation resulting from having incompatible metals in contact with each other.

cards. Before beginning these procedures, ensure that you are discharged of static electricity by
briefly touching a grounded metal object. Refer to
