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.

Questions about this item

How do I install this 288-pin DDR4 DIMM and what step is often missed?

Align the notch on the module with the slot key, press down firmly until both side clips snap shut, then verify the system reports 2933 MHz in BIOS.

What maintenance or replacement will this 8GB DDR4 module need later?

No scheduled maintenance is required; replace only if memory diagnostics report errors or capacity becomes insufficient.

What limit appears first when this CL21 1.20V module runs under sustained load?

The CL21 latency at 2933 MHz sets the throughput ceiling before voltage or thermal constraints become factors.
