4GB DDR3L 1866MHz SODIMM for Laptop Upgrade

This 4GB DDR3L module runs at 1866MHz with CL13 latency and 1.35V operation. It uses the 204-pin SO-DIMM form factor and is unbuffered non-ECC memory. The stick is designed as a direct replacement for compatible laptop and all-in-one systems.

Suits owners of Hynix HMT451S6AFR8A-RD compatible

This module matches the Hynix HMT451S6AFR8A-RD, HMT451S6BFR8A-RD and HMT451S6DFR8A-RD part numbers for straightforward upgrades. Builders needing ECC error correction or registered buffering should look elsewhere because this stick is non-ECC and unbuffered. Systems requiring a different pin count or voltage will not accept this memory.

1.35V DDR3L low-voltage specification decides fit

The 1.35V DDR3L rating is the single specification that determines whether this module works in a given machine. Standard 1.5V DDR3 slots may not support the lower voltage and DDR3L-only systems cannot use standard DDR3 modules. Verify the laptop's memory voltage requirement before ordering.

Questions about this item

Will the 1866 MHz DDR3L speed hold under sustained heavy workloads without downclocking?

The module is rated for DDR3L 1866 (PC3L-14900) operation at 1.35 V; sustained use at that speed depends on the laptop's memory controller and thermal design.

How much heat does the 1.35 V CL13 SODIMM generate during all-day operation?

At 1.35 V the DDR3L module runs cooler than standard 1.5 V DDR3, producing modest heat that typical laptop cooling handles without extra airflow.

Does my laptop need a 204-pin DDR3L slot and 1.35 V support to use this 4 GB stick?

Yes — the module is a 204-pin DDR3L SODIMM requiring a compatible DDR3L slot and 1.35 V operation; verify your system specs before installing.
