Memory Description 8-GB, PC3-12800 4-GB, PC3-12800 2-GB, PC3-12800 Spare part number 689375-001 671613-001 671612-001 The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 32-GB of memory configured in a highperforming dual channel mode. DDR3-SDRAM DIMMs For proper system operation, the DDR3-SDRAM DIMMs must be: ● industry-standard 240-pin ● unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant ● 1.35 volt or 1.5 volt DDR3/DDR3L-SDRAM DIMMs The DDR3-SDRAM DIMMs must also: ● support CAS latency 11 DDR3 1600 MHz (11-11-11 timing) ● contain the mandatory JEDEC SPD information In addition, the computer supports: ● 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies ● single-sided and double-sided DIMMs ● DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported NOTE: The system will not operate properly if you install unsupported DIMMs. Populating DIMM sockets There are four DIMM 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 B. Sockets DIMM3 and DIMM4 operate in memory channel A. 100 Chapter 6 Removal and replacement procedures: Small Form Factor (SFF)
