HP-Compatible 16GB DDR4 DIMM

This A-Tech module replaces HP part numbers 933278-001, L21496-001, L26007-001 and L40876-800 in desktop systems. It provides 16GB of DDR4 memory running at 2666MHz with CL19 latency. The unbuffered, non-ECC design targets standard desktop workloads.

Fits Standard DDR4 Desktop Slots

The 288-pin DIMM installs in any desktop motherboard that accepts DDR4 2666MHz unbuffered memory at 1.20V. No heat spreader is fitted, so the module occupies minimal vertical space inside the chassis. A single 16GB stick leaves additional slots free for future expansion.

Steady Throughput at 2666MHz

Rated at PC4-21300, the module maintains its specified frequency and CL19 timing during extended sessions. The 1.20V operation keeps power draw consistent with the DDR4 standard. Quality assurance testing validates reliability for sustained multitasking and heavier workloads.

Perguntas sobre este artigo

Will the CL19 latency become a bottleneck during long rendering sessions?

The module runs at CL19 latency at 2666 MHz; sustained workloads stay within that timing as long as the system remains stable.

Does the stick run hot or draw extra power when the desktop is on all day?

It operates at the standard 1.2 V DDR4 voltage with no heat spreader, so power draw and thermals stay at baseline DDR4 levels.

My motherboard has 288-pin DDR4 slots — is that the only requirement for this module to work?

Yes, the module is a 288-pin DDR4 DIMM at 1.2 V, non-ECC and unbuffered, matching the standard desktop slot specification.
