OWC 8GB DDR4 2400MHz SODIMM for HP Pavilion

This OWC module is an 8GB DDR4 2400MHz CL17 SODIMM built to JEDEC PC4-19200 specifications. It operates at 1.2V in a 260-pin unbuffered non-ECC layout. The part number is 2S4D42R808GB and it is validated for five HP Pavilion all-in-one model numbers.

Suited for owners of the listed HP Pavilion models

It fits the HP Pavilion 27-r039, 27-r040nz, 27-r050ns, 27-r051ns and 27-r055na. Buyers with any other system should verify compatibility before purchase. The module is backwards compatible with 2133MHz operation. It is not suited for systems requiring ECC or registered memory.

8GB capacity and DDR4 2400MHz speed

The single specification that decides fit is the 8GB capacity running at DDR4 2400MHz with CL17 timing in a 260-pin SODIMM form factor. If your HP Pavilion model matches the validated list and needs this exact speed and capacity, the module will work.

Questions about this item

How do I install the 260-pin DDR4 SODIMM in my HP Pavilion 27-r039?

Power off the system and disconnect the power cord. Remove the access panel, align the notch on the module with the slot key, insert the module until the contacts are fully seated, then press down until the side clips lock automatically.

What maintenance or replacement will this 8GB CL17 module need later?

No scheduled maintenance is required for this non-ECC unbuffered DDR4 module. Replacement is only necessary if a memory error appears or if you upgrade to a higher capacity supported by the HP Pavilion 27-r040nz platform.

What limit appears first under sustained use with this 1.2V 2400MHz memory?

The 260-pin SODIMM has no heat spreader, so thermal throttling of the memory controller can occur before the CL17 latency becomes a bottleneck during prolonged heavy workloads on the HP Pavilion 27-r050ns.
