4GB DDR4 2400MHz UDIMM for HP OMEN

This 4GB DDR4 2400MHz CL17 UDIMM is designed for HP OMEN 880-021nl, 880-021ns, 880-022na, 880-022no and 880-022ns desktops. It operates at 1.2V as a non-ECC, unbuffered 288-pin module. The single-rank 1Rx8 configuration installs without tools in compatible systems.

Capacity and headroom

A single 4GB module adds modest capacity for everyday multitasking and office workloads. The DDR4 2400 speed with CL17 latency handles standard applications and web browsing comfortably. Systems requiring larger memory footprints for content creation or virtualisation will need additional modules to avoid running out of headroom.

Thermals, noise and power draw

Running at the JEDEC standard 1.2V keeps power draw low and eliminates the need for a heat spreader. The bare PCB operates silently with no moving parts, relying on case airflow for passive cooling. Backward compatibility with 2133MHz systems allows flexible deployment without increasing thermal output.

Questions about this item

Will the 288-pin DDR4 2400MHz module run correctly alongside my existing 2133MHz sticks in the HP OMEN 880?

Yes, the module is backward compatible with 2133MHz systems and will operate at the lower speed when mixed with slower memory.

How can I verify the 4GB stick is running at CL17 1.2V after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; it should report DDR4-2400, CL17 timings and 1.2V voltage.

Does the 2U4D41R804GB package include only the UDIMM or are tools and cables supplied?

Only the 4GB 288-pin unbuffered non-ECC UDIMM is included; no tools, cables or additional hardware are provided.
