Targeted DDR3L upgrade for HP All-In-One

This 4 GB module is built for HP All-In-One models 18-5010, 18-5021, 18-5110 and 18-5202La. It suits owners who need a straightforward capacity increase on supported platforms.

204-pin SO-DIMM fits two available slots

The stick uses the 204-pin SO-DIMM form factor and runs at 1.35 V with CL11 timing. Two sockets are present in the chassis, so this single module leaves the second slot open for a future addition.

Replaces or adds to factory DDR3L memory

It matches the system DDR3L 1600 specification and lifts total memory toward the 16 GB maximum. Buyers who need ECC, registered modules or a different voltage should look elsewhere.

Questions about this item

Will the 1.35V DDR3L voltage limit stability during sustained heavy workloads?

The module runs at the standard 1.35V DDR3L voltage with CL11 11-11-11 timings, matching the HP All-in-One 18-5010 and 18-5110 specifications for continuous operation.

How much heat and noise does the unbuffered 4GB stick produce when running all day?

With no heat spreader and a low 1.35V unbuffered design, the 1Rx8 module generates minimal heat and zero noise during extended use in compatible HP All-in-One 18-5021 systems.

Which specific HP All-in-One models must I already own for this 204-pin SO-DIMM to work?

This CM5126412800SOSRL module is guaranteed compatible with HP All-in-One 18-5010, 18-5021, 18-5110 and 18-5202La systems that accept 204-pin DDR3L 1600 memory.
