256GB DDR5 ECC RDIMM Server Module

This 256GB DDR5 4800MHz ECC Registered DIMM is built for servers and workstations that require maximum memory capacity per slot. It operates at 1.10V with a CAS latency of 40 and uses a 288-pin interface. The module carries a 2S4Rx4 rank configuration with 3DS/TSV stacking.

Suits high-density server upgrades.

This module fits systems qualified for the Hynix HMCT14MEERA147N part number and DDR5 RDIMM memory. It is not compatible with desktop motherboards, consumer laptops, or any platform that only accepts unbuffered UDIMM memory. Builders needing non-ECC or lower-capacity sticks should look elsewhere.

256GB single-module capacity decides fit

The 256GB density in one RDIMM is the specification that determines whether this part works in your system. Your server or workstation must support 256GB per slot, DDR5 4800 registered ECC, and the 2S4Rx4 rank layout. Check the vendor memory QVL before purchasing.
