Targeted upgrade kit

This 16 GB kit contains two 8 GB DDR3L SODIMM modules validated for HP Pavilion All-In-One 20-B410Z, 20-B420T and 21-H010 systems. The 204-pin unbuffered sticks run at 1.35 V with CL11 timing and carry a major-brand chipset. Computer Memory Solutions guarantees compatibility with the listed models and backs the kit with a limited lifetime warranty.

Capacity and headroom

The paired modules fill both memory sockets and reach the platform maximum of 16 GB, eliminating the need to mix densities. DDR3L 1600 (PC3L 12800) speed matches the factory specification, so the system operates at its rated bandwidth without downclocking. Builders whose All-In-One already contains 16 GB or who require ECC registered memory will not benefit from this kit.

What the bundle changes

The two-stick package enables dual-channel operation on the two-slot motherboard, doubling theoretical throughput versus a single module. No heat spreader is included, keeping the low-profile form factor compatible with the slim All-In-One chassis. The lifetime exchange or repair warranty from Computer Memory Solutions covers manufacturing defects for the usable life of the modules.

Questions about this item

Will the 16GB kit (2×8GB) at 1.35V work in my HP Pavilion All-In-One 20-B410Z alongside any original modules I keep?

The kit is validated for the 20-B410Z, 20-B420T and 21-H010. Each module is DDR3L 1600 (PC3L 12800), CL11, 1.35V unbuffered SODIMM, matching the factory voltage so mixing with original DDR3L sticks is supported.

How can I verify the memory is running at DDR3L 1600 CL11 after installation?

Open Task Manager or BIOS and confirm the speed reads 1600 MHz with timings 11-11-11 at 1.35V; CPU-Z will also show 2Rx8 organisation and PC3L-12800 rating.

What exactly ships in the box and is anything else required?

The package contains two 8GB 204-pin DDR3L SODIMM modules — nothing else is needed for the upgrade.
