4 GB DDR3L SODIMM for Laptop Upgrades

This 4 GB DDR3L SODIMM module runs at 1333 MHz with CL9 latency and operates at 1.35 V. It uses the 204-pin SO-DIMM form factor and is unbuffered, non-ECC memory designed for laptop, notebook and all-in-one systems. The module is a compatible replacement for Samsung M471B5273BH1-YH9, M471B5273CH0-YH9 and M471B5273DH0-YH9 parts.

Suits owners of DDR3L platforms needing a single 4

Buyers whose systems only accept 1.5 V DDR3 modules or require ECC or registered memory should look elsewhere. Laptops limited to speeds below 1333 MHz or with no free SODIMM slot cannot use this upgrade. Anyone needing more than 4 GB per slot must choose a different capacity.

Voltage is the deciding specification

This module runs at 1.35 V, which identifies it as DDR3L low-voltage memory. A system that only supports standard 1.5 V DDR3 will not operate correctly with this part. Verify the laptop's supported memory voltage before purchase to ensure compatibility.

Questions about this item

How do I install this 204-pin DDR3L SODIMM in my laptop?

Power off the laptop, remove the battery if accessible, open the memory compartment, align the notch on the module with the slot key, insert firmly at an angle, then press down until the side clips lock.

What maintenance or replacement will this 4GB DDR3L 1333 module need later?

No routine maintenance is required; keep the laptop vents clear of dust to maintain airflow, and replace the module only if memory errors appear or capacity becomes insufficient.

What limit appears first under sustained use with this 1.35V CL9 memory?

The 1333 MHz speed and CL9 latency set the bandwidth ceiling; sustained workloads will hit that throughput limit before voltage or thermal constraints become factors.
