Populating DIMM Sockets There are two DIMM sockets on the system board. The sockets are labeled DIMM1 and DIMM2. Figure 6-10 DIMM Socket Locations Item 1 2 Description DIMM1 socket (populate first) DIMM2 socket Socket Color Black Black Installing DIMMs CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board. If you see an LED light on the system board, voltage is still present. The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other. Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. 1. Prepare the computer for disassembly (Preparation for Disassembly on page 34). 2.
