256GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit provides 256GB of DDR5 4800 registered ECC memory in a two-module configuration. Each 128GB module uses a 4Rx4 organisation and operates at 1.1V with CL40 latency. The 288-pin RDIMM form factor is built for the Dell PowerEdge XE9680 rack server.

Suited for XE9680 capacity expansion

Administrators scaling memory in a Dell PowerEdge XE9680 will find this kit matches the platform's registered ECC requirements. It is not intended for consumer desktops, workstations lacking RDIMM support, or systems that require unbuffered or non-ECC modules.

Handles large multi-tenant workloads

The 256GB total capacity supports dense virtualisation, in-memory databases and high-thread-count compute tasks on the XE9680. Workloads that exceed this per-channel limit or demand higher frequencies than 4800MT/s will require additional DIMM slots or faster-rated modules.

商品問答

Does the Dell PowerEdge XE9680 need any special BIOS setting to recognise the 4Rx4 registered ECC modules?

The kit is built to Dell specifications for the XE9680, so the server’s firmware will detect the 4Rx4 registered ECC DIMMs at 4800 MT/s without extra configuration.

Can I keep my existing DDR5 4800 RDIMMs and add this 256 GB kit in the remaining slots?

Yes, provided the other modules are also DDR5 4800 registered ECC RDIMMs; mixing ranks is supported but the system will run all channels at the lowest common speed.

How can I confirm the 256 GB kit is running at 4800 MT/s with ECC active after installation?

Check the system BIOS or iDRAC memory inventory — it will show each 128 GB DIMM at 4800 MT/s, 1.1 V, CL40 with ECC enabled.
