Capacity and Form Factor

This A-Tech module delivers 48GB of DDR5 memory in a 262-pin SODIMM package. It operates at 5600MHz with a CAS latency of 40 and runs at the standard 1.1V. The stick is unbuffered, carries ECC, and uses a dual-rank 2Rx8 organisation.

Compatibility Fit

The module suits micro-servers, mobile workstations and NAS units that explicitly support DDR5 ECC unbuffered SODIMMs. Systems limited to non-ECC memory, registered DIMMs, or earlier DDR generations cannot use this part. Buyers who need registered error correction or a different pin count should look elsewhere.

Deciding Specification

The single detail that determines fit is the ECC unbuffered SODIMM interface combined with the 2Rx8 rank structure. Only platforms qualified for that exact combination will recognise and stabilise the 48GB capacity at 5600MHz.

Questions about this item

Does the 262-pin DDR5 SO-DIMM fit my microserver's memory slot?

The module uses the standard 262-pin DDR5 SO-DIMM form factor, so it fits any slot built for DDR5 ECC unbuffered SO-DIMMs; verify your system manual for slot type and maximum capacity per slot.

What is the correct way to seat the module, and what step do installers often miss?

Align the notch with the slot key, press firmly until both side clips click shut, then confirm the system detects 48 GB at 5600 MT/s in BIOS; the step often missed is fully engaging both retention clips.

When should the 48 GB ECC module be replaced or checked for errors?

Run a memory diagnostic if you see corrected ECC errors in system logs, random reboots, or data corruption; otherwise the module is rated for continuous operation at 1.1 V with no scheduled replacement interval.
