To rotate the drive cage down, reverse this step. Memory modules (DIMMs) To remove the memory modules, use this information and procedures. For a list of available memory modules, see Computer major components on page 6. The memory sockets on the system board are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 128 GB of memory configured in a high-performing dual-channel mode. For proper system operation, the DIMMs must adhere to the following specifications: ● Industry-standard 288-pin ● 1.2 volt DDR4-SDRAM memory modules ● DDR4-3200 SDRAM UDIMM ● Mandatory JEDEC SPD information The computer supports the following setups: ● 8 Gbit, and 16 Gbit non-ECC or ECC memory technologies ● Single-sided and double-sided memory modules ● Memory modules constructed with ×8 and ×16 DDR devices; memory modules constructed with ×4 SDRAM are not supported NOTE: Memory modules support data transfer rates up to 3200 MT/s. Actual data rate is determined by system configuration. NOTE: When more than one memory slot is populated, symmetric configurations are required for two DIMMs per channel. A mix of different data transfer rates or memory rank mix within the same channel is not allowed. NOTE: The system does not operate properly if you install unsupported memory modules. There are four memory 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. 24 Chapter 4 Removal and replacement procedures

.
The memory sockets on the system board are populated with at least one preinstalled memory module. To
achieve the maximum memory support, you can populate the system board with up to 128 GB of memory
configured in a high-performing dual-channel mode.
For proper system operation, the DIMMs must adhere to the following specifications:
●
Industry-standard 288-pin
●
1.2 volt DDR4-SDRAM memory modules
●
DDR4-3200 SDRAM UDIMM
●
Mandatory JEDEC SPD information
The computer supports the following setups:
●
8 Gbit, and 16 Gbit non-ECC or ECC memory technologies
●
Single-sided and double-sided memory modules
●
Memory modules constructed with ×8 and ×16 DDR devices; memory modules constructed with ×4
SDRAM are not supported
NOTE:
Memory modules support data transfer rates up to 3200 MT/s. Actual data rate is determined by
system configuration.
NOTE:
When more than one memory slot is populated, symmetric configurations are required for two
DIMMs per channel. A mix of different data transfer rates or memory rank mix within the same channel is not
allowed.
NOTE:
The system does not operate properly if you install unsupported memory modules.
There are four memory 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.
