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.
Memory module specications
For proper system operation, the memory modules must meet the following qualications:
Table
3-2 Memory components and specications
Component Specication
Memory modules 1.2 volt DDR4-SDRAM memory modules
Compliance Unbuered non-ECC DDR4-2667 MHZ–compliant
Pins Industry-standard 260 pins containing the mandatory Joint Electronic Device
Engineering Council (JEDEC) specication
Support Support CAS latency DDR4 2667 MHz (15–15–15 timing)
Slots 2
Maximum Memory 16 GB per memory slot, 32 GB total
Supported 4 Gbit and 8 Gbit 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.
