Single-Module 48GB DDR5 Upgrade

This 48GB DDR5 5600MHz SO-DIMM delivers a full capacity upgrade in one 262-pin module. It operates at the standard 1.10V DDR5 voltage with CL40 latency and is unbuffered non-ECC. The module is a compatible replacement for IBM-Lenovo part numbers 4X71M23191 and 5M31K03110.

Laptop Owners Needing Maximum Single-Slot Capacity

The 48GB density suits users whose system supports a single high-capacity module or who want to leave a second slot free. Buyers whose laptop only accepts lower-density modules per slot, or who require ECC or registered memory, should look at a different specification.

48GB Single-Module Density

The decisive specification is the 48GB capacity on one SO-DIMM. System documentation must confirm that the platform accepts a 48GB unbuffered non-ECC DDR5 5600 module in a single slot before purchase.

Soalan tentang produk ini

Will the 262-pin DDR5 SO-DIMM fit my laptop's memory slot?

Yes, this module uses the standard 262-pin DDR5 SO-DIMM form factor used by current laptops.

What is the correct way to seat the module so it does not show errors?

Insert the stick at a slight angle until the gold contacts disappear, then press down firmly until both side clips click into the notches.

Does the 48GB stick need any firmware updates or battery replacements over time?

No, the DRAM has no battery or firmware; it only needs occasional dust removal from the contacts if the laptop is opened for service.
