Description

The Samsung M321RAGA0B20-CWK is a 128 GB DDR5 registered DIMM rated at DDR5-4800 (PC5-38400). It is a 2Rx4 module running at 1.1 V in the standard 288-pin DDR5 form factor.

It suits high-capacity server builds where capacity per slot matters more than peak speed, such as in-memory analytics, virtualization and large database servers. DDR5-4800 matches 4th Gen AMD EPYC and 4th Gen Intel Xeon Scalable platforms. Registered buffering and ECC support reliable, always-on operation. Check your server vendor's qualified memory list for this exact part number before ordering. Public pricing is not available for this module, so it is quoted on request.
