A-Tech 16GB DDR4 2666 CL19 Desktop Memory

This module is a 16GB DDR4 2666 DIMM rated at CL19 and 1.2V. It uses an unbuffered non-ECC design with a major-brand chipset and no heat spreader. The 288-pin form factor fits standard desktop memory slots. It is built as a compatible replacement for HP part 934255-800.

Suitable for HP systems requiring the 934255-800

Buyers with desktops that accept DDR4 2666 unbuffered DIMMs and need a single 16GB module will find this a direct match. Systems that require ECC, registered memory, lower latency than CL19, or a different voltage should look at other modules. Always verify the motherboard manual for supported densities and speeds before ordering.

Steady throughput at rated JEDEC settings

The module operates at the standard 1.2V DDR4 voltage with CL19 timings, so sustained workloads run within the JEDEC envelope without extra cooling. Unbuffered topology keeps signal paths short for consistent latency during long sessions. No heat spreader means the chips rely on case airflow, which is typical for this density and speed class.

Preguntas sobre este artículo

What motherboard slot does the 288-pin DIMM require to install this 16GB module?

It fits a standard desktop DDR4 DIMM socket with 288 pins; the board must support DDR4 memory at 1.2V.

Will the CL19 timing match my existing DDR4 sticks if I keep them?

The module runs at CL19; if other installed DDR4 modules have different timings the system will use the slowest common settings across all slots.

How can I confirm the 2666 MHz speed is active after installing the 934255-800 part?

Check the memory frequency in BIOS or a system-information tool such as CPU-Z; it should report 2666 MT/s (PC4-21300) for the new module.
