OWC 8GB DDR4 2666MHz CL19 UDIMM

This OWC memory module adds 8GB of DDR4 capacity at 2666MHz with CL19 timing. It is built for HP OMEN X desktops including the 900-250ng, 900-251ng, 900-280nz, 900-284nz and 900-290 models. The 1.2V unbuffered non-ECC design fits standard 288-pin desktop slots. Builders needing ECC error correction or registered modules should look elsewhere.

JEDEC and RoHS compliant specification

The module meets JEDEC standard specifications and is RoHS compliant, ensuring a warranty-safe upgrade that follows industry rules. Backward compatibility lets it run at 2133MHz or 2400MHz if the system requires a lower speed. No extra software, heat spreaders or accessories are bundled with this stick.

Simple DIY installation in most cases

Installation is a straightforward DIY task on compatible HP OMEN X systems; align the notch and press until the clips lock. The most common issue is mixing speeds, causing the system to downclock all memory to the slowest module. Systems that require registered or ECC memory will not accept this unbuffered non-ECC stick.

Questions about this item

Will the 288-pin DDR4 module need any maintenance or replacement during its service life?

The module is a solid-state component with no moving parts and no heat spreader, so it requires no routine maintenance and is designed to last the lifetime of the system under normal use.

What limit appears first when the CL19 2666MHz memory runs under sustained load?

The primary limit is the CL19 latency timing at 2666MHz; the module will not exceed this rated speed or tighten latency without manual overclocking, which is not supported by the HP OMEN X platform.

How much heat and power does the 1.2V 8GB UDIMM produce when running all day?

Operating at 1.2V without a heat spreader, the module draws minimal power and generates low heat, staying within standard JEDEC thermal limits for continuous desktop operation.
