HP ENVY PRO User Manual

Memory
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 qualications:
SODIMM 1.35 volt DDR3L-SDRAM SODIMMs
Compliance unbuered non-ECC PC4-17000 DDR4-2133 MHz-compliant
Pins industry-standard 260 pin containing the mandatory Joint Electronic Device Engineering Council
(JEDEC) specication
Support support CAS latency 11 DDR4 2133 MHz (11-11-11 timing)
Slots 2
Maximum Memory 8 GB
Supported 1 Gbit, 2 Gbit, and 4 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 SDRAMs are supported; SODIMMs constructed with x4 SDRAMS are not
supported.
HP oers 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 ex mode, depending
on how the SODIMMs are installed. Refer to the following table to identify the SODIMM channel locations.
Location System board label Channel
Lower Socket DIMM1 Channel A
Upper Socket DIMM2 Channel B
●
The system will operate in single channel mode if the SODIMM sockets are populated in one channel
only.
●
The system will operate in ex 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 ex 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.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
●
In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
To remove a memory module:
1. Prepare the computer for disassembly (see Preparing to disassemble the computer on page 17).
2. Remove the bezel (see Bezel on page 23).
