DIMMs (ProDesk 400 and 480 models) The memory sockets on the system board can be populated with up to two 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 high-performing dual channel mode. (ProDesk 490 models) The memory sockets on the system board can be populated with up to four industrystandard 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 64-GB of memory configured in a high-performing dual channel mode. DDR4-SDRAM DIMMs For proper system operation, the DIMMs must be: ● industry-standard 288-pin ● unbuffered non-ECC PC4-17000 DDR4-2133 MHz-compliant ● 1.2 volt DDR4-SDRAM DIMMs The DIMMs must also: ● support CAS latency 15 DDR4 2133 MHz (15-15-15 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. Memory 27

Memory
Description
16-GB, PC4-17000
8-GB, PC4-17000
4-GB, PC4-17000
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR4-SDRAM)
dual inline memory modules (DIMMs).
DIMMs
(ProDesk 400 and 480 models) The memory sockets on the system board can be populated with up to two
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 high-performing dual channel mode.
(ProDesk 490 models) 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 64-GB of memory
configured
in a
high-performing dual channel mode.
DDR4-SDRAM DIMMs
For proper system operation, the DIMMs must be:
●
industry-standard 288-pin
●
unbuffered
non-ECC PC4-17000 DDR4-2133 MHz-compliant
●
1.2 volt DDR4-SDRAM DIMMs
The DIMMs must also:
●
support CAS latency 15 DDR4 2133 MHz (15-15-15 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.
