Single green 288-pin DDR4 LRDIMM module with black chips and gold contacts

OWC

OWC 256GB DDR4 3200 ECC Load Reduced LRDIMM 288-pin memory upgrade

SKU CH-1D16-6SZG3

A 256GB DDR4 3200 ECC Load Reduced LRDIMM for compatible Gigabyte servers and workstations

Capacity 256GB

  • Massive 256GB capacity in a single module
  • DDR4 3200MHz CL22 for fast server responsiveness
  • ECC load-reduced design protects data integrity
  • 2V operation reduces power draw and heat
  • Backward compatible with 2133, 2400, 2666, 2933MHz systems

High-capacity server memory upgrade

This 256GB DDR4 3200 ECC Load Reduced LRDIMM targets administrators who need maximum density in a single 288-pin module. It serves Gigabyte R272-Z34, R281-Z91, R281-Z92, R281-Z94 and R282-2O0 platforms in server, workstation or NAS roles. The 1.2V design meets JEDEC and RoHS standards for warranty-safe deployment.

Load-reduced ECC architecture

The LRDIMM buffer reduces electrical load on the memory bus, allowing this 8Rx4 module to operate where standard registered DIMMs cannot. It cannot be mixed with unbuffered or registered ECC memory, so the entire channel must use identical load-reduced modules. CL22 latency and PC4-25600 rating define the timing envelope.

DDR4 3200 backward compatibility

The module runs at 3200MHz and will also operate at 2133, 2400, 2666 or 2933MHz when the platform requires a lower speed. It is not compatible with standard desktop computers or consumer motherboards. Buyers who need unbuffered or registered ECC memory must choose a different module type.

Questions about this item

Will the 288-pin ECC load-reduced DIMM need firmware updates or periodic replacement?

The module is a JEDEC-standard DDR4 part with no firmware; it runs until a hardware fault occurs and does not require scheduled replacement.

What limit appears first when the 256 GB LRDIMM runs at 3200 MHz CL22 continuously?

The DDR4 1.2 V specification and CL22 latency set the electrical and timing ceiling before thermal throttling becomes a factor.

How much heat and power does the 8Rx4 256 GB stick produce during all-day server workloads?

At 1.2 V the module draws only the power required for DDR4 3200 operation; ECC load-reduced design keeps heat low enough for standard server airflow.
