96GB DDR5 ECC RDIMM for Servers

This 96GB DDR5 module runs at 6400 MT/s with a CAS latency of 32 and operates at 1.10V. It uses a 288-pin registered DIMM form factor built with Samsung chipset components. The module is designed for server and workstation systems that require error-correcting memory.

Registered ECC with 2Rx4 Organisation

The single specification that decides fitment is the 2Rx4 registered ECC configuration. Only platforms whose memory controller supports registered DDR5 DIMMs with this rank arrangement will initialise the module correctly. Systems requiring unbuffered UDIMMs or a different rank structure cannot use this part.

No Heat Spreader Included

The module ships without a heat spreader, relying on the chassis airflow typical of 1U and 2U server designs. This keeps the profile low for dense memory populations but means the installer must ensure adequate cooling in enclosures with restricted airflow.

Questions about this item

What does the 6400 MHz speed mean once this module is installed in a server?

The module runs at DDR5 6400 MT/s, delivering PC5-51200 bandwidth when the platform memory controller is configured for that data rate.

How does the 288-pin DDR5 RDIMM interface affect what the system can use?

The registered 288-pin DDR5 DIMM fits only DDR5 RDIMM slots; the register buffers address and command signals so the memory controller sees one load per module.

What physical space and power does the 96 GB 2Rx4 module need to fit and run?

It occupies one standard 288-pin DIMM slot, draws 1.1 V, and has no heat spreader, so airflow across the bare PCB is required.
