4GB DDR4 2133MHz SODIMM for Lenovo

This A-Tech module delivers four gigabytes of DDR4 memory at 2133MHz with CL15 latency and 1.20V operation. The 260-pin SO-DIMM form factor fits compatible laptop and all-in-one systems. Major-brand chips and factory testing provide reliable performance for everyday workloads.

Suitable for compatible Lenovo laptops needing 4GB

Owners of systems that accept a single 260-pin DDR4 2133MHz SO-DIMM can use this module to restore or increase memory capacity. Builders who need ECC error correction, registered buffering, higher frequencies, lower latencies or larger individual modules should look at other parts.

260-pin DDR4 SO-DIMM form factor decides fit

The physical 260-pin DDR4 SO-DIMM interface determines whether this module installs in a given notebook or all-in-one. Systems requiring a different pin count, DDR generation, ECC support or registered design will not accept this part.

Questions about this item

Will the 260-pin DDR4 SODIMM need any cleaning or replacement parts during its service life?

No, the 260-pin DDR4 SODIMM has no moving parts and requires no routine cleaning or component replacement under normal operation.

What limit appears first when the 4 GB CL15 module runs at 2133 MHz continuously?

The 4 GB capacity is the first bottleneck, capping multitasking headroom before the CL15 latency or 2133 MHz speed become limiting factors.

How much heat and power does the 1.2 V DDR4 stick produce during all-day use?

At the standard 1.2 V DDR4 voltage the module draws minimal power and generates little heat, staying well within typical laptop thermal envelopes.
