Installing Additional Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) small outline dual inline memory modules (SODIMMs). SODIMMs The memory sockets on the system board can be populated with up to two industry-standard SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum memory support, you can populate the system board with up to 8-GB of memory.
Populating SODIMM Sockets There are two SODIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM3. The DIMM1 socket operates in memory channel A. The DIMM3 socket operates in memory channel B. Figure 2-10 SODIMM Socket Locations Table 2-1 SODIMM Socket Locations Item Description Socket Color 1 SODIMM1 socket, Channel A Black 2 SODIMM3 socket, Channel B White NOTE: A SODIMM must occupy the black DIMM1 socket.
Installing SODIMMs CAUTION: You must disconnect the power cord 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. The memory module sockets have gold-plated metal contacts.
