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 specifications
For proper system operation, the memory modules must meet the following qualifications:
