Memory
Description
16-GB
8-GB
4-GB
The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM)
dual inline memory modules (DIMMs).
DIMMs
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 congured in a high-performing
dual channel mode.
DDR4-SDRAM DIMMs
For proper system operation, the DIMMs must be:
●
industry-standard 288-pin
●
unbuered non-ECC PC4-21300 DDR4-2666 MHz-compliant
●
1.2 volt DDR4-SDRAM DIMMs
The DIMMs must also:
●
support CAS latency 16 DDR4 2666 MHz (16-16-16 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 two DIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates in memory channel
A.
The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory congurations will result in inferior graphics
performance.
