4GB DDR3L SODIMM for laptop upgrades

This 4GB DDR3L module runs at 1333MHz with CL9 latency and 1.35V operation. It fits 204-pin SODIMM slots in compatible laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design targets everyday computing workloads. Buyers who need higher capacity or faster speeds should verify their platform limits before ordering.

Direct Micron replacement with tested reliability

The module replaces Micron MT8KTF51264HZ-1G4 and MT8KTF51264HZ-1G4E1 part numbers. Each unit undergoes quality assurance testing for dependable performance. The DDR3L voltage reduces power draw compared to standard DDR3. No bundled software or accessories are included with this memory-only package.

Simple slot installation with compatibility checks

Installation requires inserting the SODIMM into an available 204-pin slot at the correct angle until it clicks. The low-profile form factor fits most laptop memory bays. Systems that only support 1.5V DDR3 or require ECC registered modules will not work with this part.

Questions about this item

Will the 204-pin DDR3L module need any firmware updates or re-seating over time?

The module is a non-ECC, unbuffered DDR3L SODIMM that installs once; no firmware or routine re-seating is required.

What limit appears first when the 1333 MHz CL9 stick runs sustained workloads?

The memory controller’s 1333 MHz ceiling and CL9 latency set the bandwidth ceiling before thermal throttling becomes a factor.

How much heat and power does the 1.35 V 4 GB module produce during all-day use?

At 1.35 V the DDR3L module draws minimal power and runs cool enough for passive laptop cooling.
