  • Boosts multitasking with 4 GB DDR3L 1600 SODIMM
  • Low 1.35 V DDR3L cuts power draw and heat
  • CL11 latency keeps data flowing at PC3L-12800 speed
  • 204-pin SO-DIMM fits standard laptop slots
  • Direct replacement for Hynix HMT351S6CFR8A-PB and HMT351S6EFR8A-PB

Direct laptop upgrade

This 4 GB DDR3L SODIMM module operates at 1600 MHz with CL11 latency and runs at 1.35 V. It is built for laptop, notebook and all-in-one systems that accept 204-pin unbuffered non-ECC memory.

Fits standard DDR3L slots

The stick installs directly into any 204-pin SO-DIMM socket wired for DDR3L 1.35 V operation. It frees a second slot for a matching module when the platform supports dual-channel configurations.

Replaces Hynix HMT351S6 parts

This module serves as a compatible equivalent for Hynix HMT351S6CFR8A-PB and HMT351S6EFR8A-PB. The upgrade is worthwhile when the system currently runs less than 4 GB or uses slower DDR3 speeds.

Questions about this item

What CAS latency does this DDR3L 1600 SODIMM run at under sustained load?

The module is specified at CL11, so that is the latency you will see once the memory has warmed up.

How much power and heat does a 1.35 V DDR3L stick add when the laptop runs all day?

At 1.35 V the module draws less power than standard 1.5 V DDR3, keeping extra heat low during continuous use.

Which slot and chipset must my laptop already have for this 204-pin DDR3L SODIMM to work?

Your system needs a DDR3L-compatible 204-pin SO-DIMM slot and a memory controller that supports 1.35 V operation.
