1TB DDR5 4800 EC8 RDIMM Kit

This 1TB kit contains eight 128GB DDR5 4800 modules built as EC8 registered DIMMs for servers and workstations. Each module runs at 1.10V with CL40 latency and uses a 2S2Rx4 quad-rank 3DS layout. The registered design adds a buffer that stabilises heavy memory loads in multi-socket systems.

Verify DDR5 RDIMM support and slot count

Confirm that your platform accepts DDR5 registered ECC memory and provides at least eight 288-pin DIMM slots. Desktop and laptop boards cannot use these modules. Check the system manual for supported speeds, maximum capacity per channel and required population rules before ordering.

Fills eight slots in a registered DDR5 server

The kit occupies eight DIMM sockets and delivers 1TB of registered ECC capacity for virtualisation, database or compute workloads. It requires a motherboard with a DDR5 registered memory controller and sufficient electrical loading headroom for quad-rank modules. No desktop or consumer hardware is supported.

Questions about this item

Does the kit ship with eight 128 GB DDR5 RDIMMs or do I need to buy additional modules?

The kit contains eight 128 GB DDR5 4800 EC8 RDIMM modules for a total of 1 TB; no extra modules are required.

When should I choose the 2S2Rx4 quad-rank 3DS version instead of a lower-rank alternative?

Choose the 2S2Rx4 (4Rx4) quad-rank 3DS configuration when your server or workstation memory controller supports quad-rank x4 3DS/TSV modules and you need maximum density per DIMM slot.

What real-world effect does the DDR5 4800 CL40 1.1 V spec have inside a compatible server?

The DDR5 4800 CL40 1.1 V rating delivers the standard DDR5 data rate and latency for registered ECC workloads, letting the memory controller run at its rated 4800 MT/s without overclocking.
