Targeted HP Envy 27 upgrade

This 4GB DDR4 SODIMM is built specifically for HP Envy 27 all-in-one models including the 27-b105nl, 27-b107na, 27-b109na, 27-b110 and 27-b110nb. It provides a direct, warranty-safe memory increase for owners of those systems who need more capacity for everyday multitasking. The module arrives new and ready to install without configuration changes.

Steady throughput at JEDEC limits

Rated at 2133MHz with CL15 latency and 1.2V operation, the module delivers consistent bandwidth during extended workloads rather than only in short bursts. Unbuffered, non-ECC construction and 1Rx8 organisation keep signal timing stable across long sessions. JEDEC compliance ensures the memory sustains its rated speed without relying on overclocking headroom that the platform cannot use.

DDR4 SODIMM ceiling for this platform

The 260-pin DDR4 interface tops out at the PC4-17000 data rate on these Envy 27 systems, so this module reaches the practical ceiling the chipset and firmware allow. Builders who need more storage or a second graphics card cannot address those needs with memory alone. The single 4GB rank also means total capacity is limited by the number of slots the mainboard provides.

Questions about this item

Does the 1.2V DDR4 module run cool inside an HP Envy 27 all-in-one all day?

The SODIMM operates at the standard 1.2 V DDR4 voltage and has no heat spreader, so it draws minimal power and stays cool during continuous use.

What must the HP Envy 27 already have to accept this 260-pin SODIMM?

The system needs a free DDR4 SO-DIMM slot that supports 2133 MHz PC4-17000 non-ECC unbuffered memory.

Will this CL15 2133 MHz stick work alongside the original memory in an Envy 27-b110?

Yes, it matches the factory speed, latency and voltage, so it will run in dual-channel with the existing module.
