Memory

Description
16-GB
8-GB
4-GB
The computer comes with small outline dual inline memory modules (SODIMMs).
The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM.
For proper system operation, the SODIMMs must meet the following qualifications:
SODIMM

Slots

Note
HP offers upgrade memory for this computer and advises that the consumer purchase it to avoid
compatibility issues with unsupported third-party memory.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the SODIMMs are installed. Refer to the following table to identify the SODIMM channel locations.
Location
Lower Socket
Upper Socket
● The system will operate in single channel mode if the SODIMM sockets are populated in one channel
only.
● The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not equal to
the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated with the least
amount of memory describes the total amount of memory assigned to dual channel and the remainder
is assigned to single channel. If one channel will have more memory than the other, the larger amount
should be assigned to channel A.
