256GB DDR4 LRDIMM for servers

This 256GB DDR4 2933 load-reduced DIMM targets enterprise servers that require high-capacity registered memory with error correction. The single-module kit suits administrators upgrading compatible platforms without populating every slot. It is not intended for standard desktop or workstation motherboards.

Build integration and platform needs

The module uses a 288-pin DDR4 interface at 1.2V and presents an 8Rx4 organisation to the memory controller. A motherboard qualified for PC4-23400 LRDIMMs with ECC support is required; consumer chipsets will not recognise the load-reduced design. The CAS latency of 21 cycles is fixed by the module SPD.

What the kit includes and enables

One 256GB stick delivers the full density in a single slot, freeing remaining DIMM positions for further expansion. The ECC and load-reduced buffering maintain signal integrity on heavily populated channels. Major OEM DRAM from Samsung, Micron or Hynix underpins the lifetime replacement warranty.

Questions about this item

What limits sustained performance of the 8Rx4 LRDIMM under continuous load?

The 8Rx4 load-reduced design reduces electrical load on the memory bus, allowing the module to run at DDR4 2933 with CAS 21 without rank-related throttling.

How much heat and power does the 256GB LRDIMM produce during all-day operation?

Operating at 1.2V, the module draws less power per gigabyte than standard registered DIMMs, so heat output stays low inside a server chassis with normal airflow.

Which server platform must I already have for this 288-pin DDR4 2933 module to work?

A system with DDR4 2933 (PC4-23400) memory slots that accept 288-pin ECC LRDIMMs and support 8Rx4 rank configurations.
