256GB DDR4 2933 LRDIMM Kit

This 256GB kit contains four 64GB DDR4 2933 LRDIMM modules operating at 1.2V with CL21 latency. The load-reduced design and ECC support target enterprise servers that require high-density registered memory. Each module uses a 4Rx4 organisation and a 288-pin form factor for compatible server platforms.

Server Upgrades Not PC Builds

The modules suit administrators upgrading qualified DDR4 servers that accept 4Rx4 LRDIMM populations at 2933MT/s. They do not fit standard desktop motherboards or workstations lacking LRDIMM support and registered memory controllers. Buyers needing unbuffered DIMMs or non-ECC memory for consumer platforms should select a different product type.

4Rx4 Load-Reduced Organisation

The 4Rx4 rank configuration reduces electrical load on the memory bus, allowing the full 256GB capacity to run at the rated 2933MT/s speed on supported server chipsets. Systems limited to lower rank counts or single-rank modules cannot utilise this kit at its specified density and frequency. Verify the server qualified-vendor list for 4Rx4 LRDIMM compatibility before purchase.

Questions about this item

Will these 288-pin DDR4 LRDIMMs fit my server board?

These modules use the standard 288-pin DDR4 LRDIMM form factor. They require motherboard slots that support load-reduced registered ECC DDR4 at 1.2 V.

What is the correct seating procedure for the 4Rx4 modules?

Align the notch with the slot key, press straight down until both side clips click, and verify the 4Rx4 rank configuration is recognised in BIOS before closing the chassis.

How long do the Samsung, Micron or Hynix chips on these ECC LRDIMMs typically last?

The major OEM DRAM chips are rated for continuous server operation. ECC corrects single-bit errors, and the modules carry a lifetime replacement warranty from the manufacturer.
