OWC 4GB DDR3L 1600 SODIMM

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It fits laptops, all-in-one systems and NAS devices that accept 204-pin SO-DIMM memory. The non-ECC, unbuffered design matches standard consumer platforms.

Sustained load behaviour

JEDEC-standard timings and low-voltage DDR3L operation keep power draw steady during extended workloads. The module maintains rated 1600MHz throughput without thermal throttling because it has no heat spreader to trap heat in tight chassis.

Installation notes

The 204-pin edge connector slots directly into compatible SO-DIMM sockets with a simple press until the retention clips click. The main risk is buying DDR3L for a system that only supports 1.5V DDR3, or vice versa, because the key notch position differs between voltage variants.

Questions about this item

How much power does this 1.35 V DDR3L module draw when the laptop runs all day?

It operates at 1.35 V, the standard DDR3L voltage, so power draw stays low during continuous use.

What must my laptop already have for this 204-pin SODIMM to fit and work?

A free 204-pin DDR3 SODIMM slot that accepts 1.35 V unbuffered non-ECC memory.

Will this CL11 1600 MHz stick run stably beside the original memory already in my system?

Yes — it meets JEDEC DDR3L 1600 CL11 specs, so the memory controller will match timings automatically.
