achie
ve the maximum memory support, you can populate the system board with up to 128 GB of memory
congured in a high-performing dual-channel mode.
For proper system operation, the DIMMs must adhere to the following specications:
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:
512 Mbit, 1 Gbit, 2 Gbit, and 4 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
SDR
AM are not supported
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.
