32GB DDR5 4800 ECC SODIMM for Microservers

This 32GB DDR5 4800 CL40 ECC SODIMM operates at 1.10V and uses a 262-pin unbuffered design. It is built as a compatible replacement for the Samsung M426R4GA3BB0-CQK module. The memory targets microserver, server and workstation systems that require error-correcting code capability.

Suits ECC-capable DDR5 platforms needing 32GB

Buyers whose laptops or desktops lack ECC support in the memory controller should look elsewhere, as the extra parity bits provide no benefit on non-ECC hardware. Systems limited to lower DDR5 speeds or different pin counts also cannot use this module.

262-pin DDR5 SO-DIMM form factor decides fit

The module installs only in slots wired for 262-pin DDR5 SO-DIMMs with ECC unbuffered signalling. Verifying that the platform explicitly supports this exact form factor and ECC type is the single step that confirms compatibility.

Questions about this item

What speed does the DDR5 4800 interface actually run at?

The module operates at DDR5 4800 MHz, labelled PC5-38400, which is the standard data rate for this specification.

Will the 262-pin SO-DIMM fit my laptop slot?

Yes, it uses the standard 262-pin DDR5 SO-DIMM form factor, so it fits any socket that accepts DDR5 laptop memory.

How do I install the module and what step is often missed?

Power off the system, open the memory door, align the notch on the 262-pin module with the slot key, press firmly until the side clips click, then verify the new 32 GB capacity in BIOS.
