In addition, the computer supports:
●
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMs
●
SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
Populating SODIMM sockets
The memory sockets on the system board can be populated with up to four 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 16 GB of memory.
There are four SODIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel A. Sockets DIMM3 and DIMM4 operate in memory channel B.
Figure 7-21 SODIMM socket locations
Table 7-1 SODIMM socket locations
Item Description Socket Color
1 DIMM1 socket, Channel A (populate first) black
2 DIMM2 socket, Channel A (populate third) white
3 DIMM3 socket, Channel B (populate second) black
4 DIMM4 socket, Channel B (populate fourth) white
NOTE: A SODIMM must occupy the black DIMM1 socket. Otherwise, the system will display
a POST error message indicating that a memory module is installed in the wrong socket
