Server DDR5 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR5 modules built for servers and workstations that require ECC registered memory. Each module runs at 4800 MHz with CL40 latency and operates at the standard 1.10V. The dual-rank x8 organisation and 288-pin RDIMM form factor are designed for registered memory slots only.

For registered DDR5 platforms only

It suits administrators upgrading compatible DDR5 servers or workstations that explicitly support ECC RDIMM modules. It will not work in desktop or laptop systems, nor in platforms that require unbuffered or non-ECC memory. Buyers who need consumer DIMMs or a different capacity should look elsewhere.

Steady throughput under load

Registered buffering and on-die ECC keep data integrity intact during sustained, multi-threaded workloads. The 1.10V operation helps maintain thermal stability when all eight modules are fully populated. Performance scales with the platform's memory controller and channel configuration.

Questions about this item

Does my server need DDR5 RDIMM slots to use this 256GB kit?

Yes, this kit requires a server or workstation with DDR5 RDIMM slots; it is not compatible with desktop or laptop computers.

Can I mix these 2Rx8 EC8 modules with existing DDR5 RDIMMs of a different rank?

Mixing ranks is possible on many platforms, but you should consult your system manual for supported population rules and channel guidelines.

How can I confirm the kit is running at DDR5 4800 CL40 after installation?

Check the memory speed and timings in your system BIOS or use a tool like CPU‑Z to verify 4800 MHz and CL40 operation.
