Green rectangular 288-pin DDR4 LRDIMM module with black chips and gold contacts

OWC

OWC 256GB DDR4 3200 ECC LRDIMM 288-pin 1.2V memory upgrade

SKU CH-S1HS-ECEB5

A single 256 GB DDR4 3200 ECC load-reduced DIMM for compatible Gigabyte servers and workstations

Capacity 256GB

  • Massive 256 GB capacity powers heavy server workloads
  • ECC load-reduced design protects data integrity in critical systems
  • DDR4 3200 MHz CL22 speed accelerates throughput for demanding applications
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz platforms

Single 256 GB module

This OWC DDR4 3200 ECC load-reduced DIMM delivers 256 GB in a single 288-pin module rated at PC4-25600 CL22 and 1.2 V. It targets servers, workstations and NAS systems that require maximum density per slot and error-correcting memory protection.

Build integration

The module fits 288-pin DDR4 slots on platforms such as the Gigabyte R182-Z90, R182-Z91, R182-Z92, R182-Z93 and R262-ZA0. It cannot be mixed with unbuffered or registered ECC DIMMs, so the entire memory subsystem must use load-reduced modules. Backward compatibility with 2133, 2400, 2666 and 2933 MHz buses allows deployment in older platforms without replacing the full kit.

Sustained operation

JEDEC-standard compliance and load-reduced buffering reduce electrical load on the memory controller during continuous workloads. ECC circuitry corrects single-bit errors on the fly, maintaining data integrity through extended compute or storage tasks. The 1.2 V operating voltage keeps power draw predictable under prolonged utilisation.

Questions about this item

What is the CAS latency of this 256GB DDR4 3200 module?

The module runs at CL22, which is the timing specified for PC4-25600 3200MHz operation.

How much power does the 1.2V LRDIMM draw under continuous server load?

It operates at the standard DDR4 1.2V; actual wattage depends on the platform's memory controller and sustained bandwidth demand.

Which motherboard memory slots accept this 288-pin ECC load-reduced DIMM?

It fits 288-pin DDR4 slots that support ECC LRDIMM, such as those on Gigabyte R182-Z90, R182-Z91, R182-Z92, R182-Z93 and R262-ZA0.
