4 GB DDR3 SODIMM for laptop upgrades

This 4 GB DDR3 SODIMM module runs at 1600 MHz with CL11 timing and 1.5 V operation. It uses a 204‑pin unbuffered, non‑ECC design built with major‑brand chips. The single‑stick kit suits notebooks or small‑form‑factor systems that accept DDR3 SO‑DIMM memory.

Low‑voltage DDR3 runs cool and quiet

Operating at 1.5 V keeps power draw modest and heat output low in everyday workloads. The unbuffered layout adds no extra circuitry that would increase thermal load. No active cooling is required, so the module stays silent inside thin‑and‑light chassis.

Replaces a single DDR3 stick or adds 4 GB capacity

Swapping out a slower or smaller DDR3 module restores full 1600 MHz speed when paired with a matching stick. The upgrade is worthwhile when the system currently runs below 1600 MHz or has an empty SO‑DIMM slot. Buyers needing more than 4 GB per slot or a different voltage should look elsewhere.

Questions about this item

How do I install this 204-pin SODIMM and what step do people often miss?

Align the notch with the slot key, insert at an angle, then press down until both side clips click; the step often missed is pushing firmly enough to engage both clips fully.

Will this 4GB DDR3 module need any maintenance or replacement later?

No routine maintenance is required; if a fault appears, the manufacturer provides a limited lifetime exchange or repair against manufacturing defects.

What limit appears first when this CL11 1.5V kit runs under sustained load?

The 1600 MHz speed ceiling and CL11 latency are the first bottlenecks; all installed memory will run at the slowest module or CPU capability.
