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
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

Specification
Memory modules
1.2 volt DDR4-SDRAM memory modules
Compliance
Unbuffered
non-ECC DDR4-2666 MHZ–compliant
Pins
Industry-standard 260 pins containing the mandatory Joint Electronic Device
Engineering Council (JEDEC)

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.
HP
offers
upgrade memory for this computer and advises that the consumer purchase it to avoid
compatibility issues with unsupported third-party memory.
Populating memory modules
Refer to the following table to identify the memory module channel locations.
Location
System board label
Channel
Lower Socket
SODIMM1
Channel B
Upper Socket
SODIMM3
Channel A
The system will automatically operate in single channel mode, dual channel mode, or
flex
mode, depending
on how the memory modules are installed.
●
The system will operate in single channel mode if the memory module slots are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
memory module in Channel A is equal to the memory capacity of the memory module in Channel B.
●
The system will operate in
flex
mode if the memory capacity of the memory module in Channel A is not
equal to the memory capacity of the memory module 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
