A-Tech 8GB DDR4 2933MHz CL21 desktop RAM L89419-001

HP-compatible 8 GB DDR4 module

This 8 GB DDR4 DIMM is a direct replacement for HP part L89419-001 and suits desktop owners who need a simple capacity increase. It runs at 2933 MHz with CL21 latency and standard 1.2 V operation. The unbuffered, non-ECC design matches typical consumer motherboards. One 288-pin module provides the full 8 GB in a single slot.

Thermals and power in daily use

Without a heat spreader the module relies on case airflow, which is sufficient at the low 1.2 V voltage. Power draw stays modest during typical desktop workloads such as office applications and web browsing. The standard JEDEC voltage avoids extra strain on the memory controller. Acoustic impact is negligible because the stick has no moving parts.

Build and connector notes

The green PCB uses major-brand chips and carries the 288-pin DDR4 keying, so it seats firmly in any compatible desktop slot. Absence of a heat spreader keeps the profile low for tight spaces near large CPU coolers. The 262-pin DIMM form factor mentioned in supplier data refers to the SO-DIMM standard; this module is the 288-pin desktop DIMM. Lifetime warranty and US-based support are offered by the manufacturer.
