Purpose-built upgrade

This 4 GB DDR4 SODIMM is engineered for HP Pavilion 27-a027c, 27-a030, 27-a030qe, 27-a031 and 27-a040se all-in-one desktops. It targets owners of those specific models who need a straightforward capacity increase without compatibility guesswork.

Slot-level fit

The module uses the standard 260-pin DDR4 SO-DIMM form factor and runs at 1.2 V, matching the voltage and keying of the factory-installed memory. It occupies a single slot, leaves any second slot free for future expansion, and requires no BIOS changes or additional cooling.

Steady-state behaviour

Rated at 2133 MHz with CL15 latency, the stick delivers consistent throughput during extended multitasking sessions because it operates within JEDEC limits and produces minimal extra heat. The absence of a heat spreader is unproblematic in the Pavilion chassis, where airflow is designed for low-profile modules.

Questions about this item

Will the CL15 latency limit throughput during long editing sessions?

CL15 is the rated CAS latency for this DDR4 2133 module; it runs at the JEDEC standard timing and does not impose an additional bottleneck beyond the memory controller's own limits.

Does the stick run hot or draw extra power after hours of continuous load?

The module operates at the standard 1.2 V with no heat spreader; power draw and thermals stay within normal DDR4 SODIMM limits for all-day use.

Which HP Pavilion all-in-one models accept this 260-pin SODIMM?

Tested compatible with HP Pavilion 27-a027c, 27-a030, 27-a030qe, 27-a031 and 27-a040se.
