OWC 256GB DDR4 3200 ECC Load Reduced LRDIMM 288-pin for Gigabyte R182-N20 NA0 NA1 NC0 P91

SKU CH-AHBW-GJ6EF

256 GB DDR4 ECC load-reduced DIMM running at 3200 MHz CL22 for Gigabyte R182 server platforms

Capacity 256GB

  • Single 256 GB module doubles server capacity
  • ECC load-reduced design protects data integrity in critical workloads
  • DDR4 3200 MHz CL22 speed accelerates memory-intensive applications
  • 2 V operation lowers power draw per gigabyte
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

OWC 256GB DDR4 3200 LRDIMM

This 256GB DDR4 3200 ECC Load Reduced LRDIMM is built for Gigabyte R182-N20, NA0, NA1, NC0 and P91 servers and workstations. It delivers 256GB in a single 288-pin module running at 1.2V with CL22 latency. The memory targets IT teams that need maximum density per slot in compatible platforms.

Replaces lower-density DDR4 LRDIMMs

The module upgrades from smaller LRDIMM capacities to 256GB per slot, letting you reach higher total memory without adding modules. It is backward compatible with 2133, 2400, 2666 and 2933MHz systems, so the jump is worth it when your board supports LRDIMM and you need more capacity per channel. It will not work with unbuffered or registered ECC DIMMs and cannot be mixed with them.

Sustained load behaviour

JEDEC-standard PC4-25600 timing and 1.2V operation keep signal integrity stable during long server workloads. The load-reduced buffer reduces electrical load on the memory controller, helping maintain consistent throughput under continuous demand. ECC corrects single-bit errors in real time, protecting data integrity through extended uptime.

Questions about this item

Does the 288-pin LRDIMM fit a Gigabyte R182-N20 motherboard?

The module uses the standard 288-pin DDR4 LRDIMM form factor, which matches the Gigabyte R182-N20, R182-NA0, R182-NA1, R182-NC0 and R182-P91 server boards listed for this upgrade.

What is the correct installation step for this 8Rx4 ECC load-reduced DIMM?

Insert the single 256 GB stick into an empty DDR4 slot with the notch aligned, press firmly until the retention clips click, and do not mix it with unbuffered or registered ECC memory.

When should the 1.2 V DDR4 module be replaced in a server?

Replace it if memory diagnostics report correctable ECC errors that become uncorrectable, if the system fails POST with this DIMM installed, or when a capacity upgrade beyond 256 GB is required.
