256GB DDR5 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR5 ECC RDIMM modules built for servers and workstations that require registered memory with error correction. The 4Rx4 organisation and 1.10V operating voltage target enterprise platforms designed for high-density memory configurations. Buyers deploying virtualisation hosts, database nodes or compute clusters will match the capacity and reliability profile.

Platform Requirements Check

Verify that your motherboard supports DDR5 RDIMM modules, registered operation and 4Rx4 rank density at 4800 MT/s. The memory controller must accept 288-pin ECC registered DIMMs at 1.10V and the BIOS must be current enough to initialise the full 256GB capacity. Systems limited to UDIMM, lower rank counts or slower speeds will not post with this kit.

Build Integration

The modules occupy two DIMM slots and leave remaining channels free for further expansion up to the platform limit. Registered buffering reduces electrical load on the memory controller, helping stability when all slots are populated. No heat spreaders are fitted, so airflow across the bare PCBs must be provided by the server chassis cooling design.

Questions about this item

Does the 256 GB kit include two 128 GB modules or do I need to buy extra sticks?

The kit ships with two 128 GB DDR5 RDIMM modules for a total of 256 GB.

Should I choose the 4Rx4 4800 MT/s version or a different rank and speed?

This kit is 4Rx4 at 4800 MT/s; select it when your server requires registered ECC DDR5 at that rank and data rate.

What does the CL40 latency mean once the memory is installed in a server?

CL40 indicates 40 clock cycles of CAS latency at the rated 4800 MT/s speed, which the memory controller uses for timing.
