Capacity and compatibility

This 4GB DDR3L SODIMM module runs at 1866MHz with CL13 latency and 1.35V operation. It targets owners of laptops, notebooks or all-in-one systems that accept 204-pin unbuffered non-ECC memory and need a straightforward capacity increase.

Installation and system impact

The stick fits a single 204-pin SO-DIMM slot and requires a platform that supports DDR3L 1.35V signalling. Adding it frees the existing memory controller from paging pressure, allowing more applications to stay resident without swapping to storage.

Sustained workload behaviour

Rated for PC3L-14900 bandwidth, the module maintains its 1866MHz data rate during extended multitasking or background processing. The low-voltage design keeps thermal output modest, so throttling is unlikely during long sessions. Systems limited to lower DDR3 speeds or 1.5V-only slots will not be compatible.

Highlights

Questions about this item

Will the CL13 latency at 1866MHz become a bottleneck during long rendering sessions?

The module runs at CL13 with a 1866MHz data rate, so latency is fixed by the JEDEC DDR3L specification for this speed grade.

How much heat does the 1.35V DDR3L module generate under continuous load?

At 1.35V the DDR3L SODIMM draws less power than standard 1.5V DDR3, producing minimal heat that typical laptop cooling handles without extra airflow.

My laptop has a 204-pin DDR3 slot — is that the only requirement for this module to work?

Yes, the stick is a 204-pin DDR3L SODIMM rated at 1.35V, non-ECC and unbuffered, matching the slot and voltage your system provides.
