OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM server RAM

SKU CH-6229-7TRX4

A 256GB DDR4 3200 ECC load-reduced DIMM for servers, workstations and NAS systems with 288 pins, CL22 latency, 1.2V operation and backward compatibility to 2133, 2400, 2666 and 2933MHz

  • 256 GB capacity lets servers handle massive workloads
  • DDR4 3200 PC4-25600 CL22 delivers high throughput at 1.2 V
  • ECC load-reduced design supports dense 8Rx4 configuration
  • 288-pin LRDIMM fits server, workstation and NAS platforms
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Server-grade 256 GB DDR4 LRDIMM

This 256 GB DDR4 load-reduced DIMM is built for servers, workstations and NAS systems that require ECC load-reduced memory. It will not work in standard desktop computers and cannot be mixed with unbuffered or registered ECC modules. The module uses a 288-pin form factor and operates at 1.2 V.

Speed limits and backward compatibility

The module runs at PC4-25600 3200 MHz with CL22 latency. It is backward compatible with 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz platforms, so it will clock down to match the slowest installed DIMM. Mixing different ECC types or using it in a consumer board will prevent the system from posting.

Capacity and rank configuration

The single 256 GB stick uses an 8Rx4 organisation to deliver high density per slot. This makes it suitable for configurations that need maximum memory in a limited number of DIMM sockets. Buyers who need a different rank structure or a smaller capacity per module should look elsewhere.

Highlights

  • 256 GB capacity lets servers handle massive workloads

  • ECC load-reduced design supports dense 8Rx4 configuration
  • 288-pin LRDIMM fits server, workstation and NAS platforms
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Questions about this item

Is the 256GB module sold individually or in a kit?

The listing describes a single 256GB DDR4 3200 LRDIMM; order one module per slot you intend to populate.

What does the PC4-25600 3200MHz CL22 rating deliver in a server?

It provides a peak transfer rate of 25600 MB/s at 3200 MT/s with CAS latency 22 when the platform runs at the rated speed.

Will the 288-pin LRDIMM work in a board that only supports registered ECC?

No — load-reduced ECC cannot be mixed with registered ECC; the motherboard must explicitly support LRDIMM modules.
