4GB DDR4 260-Pin SODIMM

This A-Tech module provides 4GB of DDR4 memory in a 260-pin SODIMM form factor. It operates at 2400MHz with a CAS latency of CL17 and a standard voltage of 1.20V. The unbuffered, non-ECC design targets laptop, notebook and all-in-one systems requiring a direct replacement for specific Samsung part numbers.

Suits owners of compatible laptops needing a 4GB

Buyers whose systems require ECC or registered memory should look elsewhere. Systems limited to slower DDR4 speeds or different pin counts cannot use this module. The single 4GB capacity may not meet the needs of users requiring higher total memory configurations.

DDR4 2400MHz CL17 specification

The decisive specification is the DDR4 2400MHz speed combined with CL17 latency at 1.20V. Verify that your laptop supports this exact speed, voltage and 260-pin SODIMM form factor before purchasing. Compatibility with Samsung M471A5244BB0-CRC and M471A5244CB0-CRC references is confirmed.

この商品に関する質問

Will this 260-pin DDR4 SODIMM fit my laptop's memory slot?

Yes, the module uses the standard 260-pin DDR4 SO-DIMM form factor used by most modern laptops and all-in-one PCs.

What is the correct way to seat the module so it locks in properly?

Align the notch with the slot key, insert at a slight angle, press down firmly until both side clips click into the notches on the module edges.

Does this 1.2V DDR4 module need any cooling or replacement over time?

No active cooling is required; DDR4 runs at 1.2V standard voltage and has no moving parts, so it typically lasts the lifetime of the laptop.
