Removing and installing memory

The memory slots on the system board can be populated with up to two industry-standard small outline dual

inline memory modules (SODIMMs). These memory slots are populated with at least one preinstalled memory

module. A metal shield protects the memory modules.

Memory module specications

For proper system operation, the memory modules must meet the following qualications:

Component Specication

Memory modules 1.2 volt DDR4-SDRAM memory modules

Compliance Unbuered non-ECC DDR4-2666 MHz SODIMM compliant

Pins Industry-standard 260 pins containing the mandatory Joint Electronic Device

Engineering Council (JEDEC) specication

Support Support CAS latency 19 DDR4 2666 MHz (19-19-19 timing)

Slots 2

Maximum Memory 16 GB per memory slot, 32 GB total

Supported 8 Gbit (base) non-ECC memory technologies single-sided and double-sided SODIMMs

Note The system will not operate properly if you install unsupported SODIMM

memory. SODIMMs constructed with x8 and x16 DDR devices are supported; memory

modules constructed with x4 SDRAM are not supported.
