Server-grade DDR4 kit for high-capacity workloads

This 256 GB kit contains two 128 GB registered ECC modules rated at DDR4 2933 (PC4-23400). It is built for servers and workstations that require error-correcting memory and registered signalling. Standard desktop PCs cannot use these modules.

Registered design with 4Rx4 organisation

Each module uses a 4Rx4 layout and operates at 1.2 V through a 288-pin RDIMM interface. The registered buffer reduces electrical load on the memory controller, allowing higher densities per channel. CAS latency is 21 cycles at the rated speed.

DDR4 2933 bandwidth ceiling limits peak throughput

The PC4-23400 rating sets a maximum theoretical transfer rate that cannot be exceeded by this kit. Systems needing higher memory bandwidth must move to a faster DDR4 grade or a newer memory generation. Capacity per module is fixed at 128 GB, so expanding beyond 256 GB requires additional DIMM slots.

Questions sur cet article

Does DDR4 2933 PC4-23400 limit the bus speed to 2933 MT/s?

Yes, the DDR4 2933 rating means the modules run at up to 2933 MT/s, which corresponds to the PC4-23400 bandwidth specification.

Will these 288-pin ECC RDIMMs fit a standard server DIMM slot?

Yes, each 128 GB module uses the 288-pin DDR4 RDIMM form factor, so they install in any server board with matching DDR4 RDIMM slots.

How are the two 128 GB sticks installed, and what step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then verify in BIOS that all 256 GB are recognised at 2933 MT/s.
