Green 288-pin DDR4 LRDIMM module with black memory chips and gold edge connectors

OWC

OWC 256GB DDR4 3200 ECC LRDIMM 288-pin 1.2V CL22 memory upgrade

SKU CH-R83W-7C3BY

Single 256 GB DDR4 3200 MHz ECC load-reduced DIMM for servers and workstations, 288-pin CL22 at 1.2 V

Capacity 256GB

  • 256 GB capacity handles large server workloads
  • DDR4 3200 MHz CL22 speed matches platform specs
  • ECC load-reduced design protects data integrity
  • 2 V operation reduces power draw
  • Backward compatible with 2133, 2400, 2666, 2933 MHz systems

Server-grade capacity

This 256 GB DDR4 LRDIMM delivers a single-module upgrade for Gigabyte G292-280, G292-2G0, E152-ZE0, E152-ZE1 and E162-220 servers and workstations. It targets administrators who need maximum density in a 288-pin slot without mixing registered or unbuffered DIMMs.

Thermals and power

The module runs at 1.2 V and meets JEDEC PC4-25600 timing at CL22, keeping power draw low for high-density configurations. Load-reduced architecture reduces electrical load on the memory controller, helping maintain stable thermals in multi-DIMM populated chassis.

Build and mounting

ECC load-reduced design adds error correction and signal buffering suited to 24/7 server and NAS workloads. The 288-pin form factor fits standard DDR4 server slots, and backward compatibility with 2133, 2400, 2666 and 2933 MHz systems allows phased upgrades across mixed-speed platforms.

Questions about this item

How do I install the 256GB DDR4 3200 ECC LRDIMM and what step is often missed?

Insert the 288-pin module into a compatible DDR4 LRDIMM slot until the retention clips lock; the step often missed is confirming the platform requires ECC load-reduced memory and does not mix unbuffered or registered DIMMs.

What maintenance or replacement will this 256GB DDR4 3200 ECC LRDIMM need later?

No scheduled maintenance is required; replacement is only needed if a module fails, which is covered by the limited lifetime warranty and advanced replacement program.

What limit appears first on this 256GB DDR4 3200 ECC LRDIMM under sustained server workloads?

The CL22 latency at 3200MHz sets the timing boundary; sustained throughput is capped by the PC4-25600 data rate and the platform's memory controller.
