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

SKU CH-WFGH-9CPVW

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

  • 256 GB capacity supports large server workloads
  • DDR4 3200 MHz CL22 delivers high-speed data throughput
  • ECC load-reduced design maintains signal integrity at scale
  • 2 V operation reduces power draw per module
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

256 GB DDR4 LRDIMM for servers

This 256 GB DDR4 module is an ECC load-reduced DIMM built for servers, workstations and NAS systems. It targets administrators who need maximum capacity per slot in enterprise platforms. It is not for standard desktop computers and cannot be mixed with unbuffered or registered ECC memory.

3200 MHz CL22 with backward speeds

Rated at PC4-25600 3200 MHz CL22, the module delivers high bandwidth for virtualization and large datasets. It also runs at 2933 MHz, 2666 MHz, 2400 MHz and 2133 MHz when the platform requires a lower speed. Capacity per slot is fixed at 256 GB; configurations needing more memory must populate additional slots.

288-pin 1.2 V JEDEC form factor

The 288-pin LRDIMM fits DDR4 server boards that support load-reduced memory at 1.2 V. JEDEC and RoHS compliance ensure a warranty-safe upgrade without proprietary lock-in. Systems must provide LRDIMM-capable memory controllers; unbuffered or registered-only platforms will not accept this module.

Highlights

  • ECC load-reduced design maintains signal integrity at scale
  • 2 V operation reduces power draw per module
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Questions about this item

Will this 288-pin LRDIMM run alongside my existing 2666 MHz DDR4 modules in a server?

Yes, the module is backward compatible with 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz DDR4 speeds, but LRDIMM cannot be mixed with unbuffered or ECC registered memory types.

How can I verify the 256 GB LRDIMM is operating at the correct 3200 MHz CL22 timings after installation?

Check the system BIOS or UEFI memory information screen; it should report PC4-25600 3200 MHz with CL22 latency and show ECC load-reduced status for the installed module.

Does the package include any heatsinks, cables or installation tools for the 288-pin module?

The module ships as a single 256 GB DDR4 LRDIMM only; no heatsinks, cables or tools are included and none are required for standard server DIMM slot installation.
