Green rectangular DDR4 LRDIMM module with black memory chips on both sides and gold 288-pin edge connector

OWC

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

SKU CH-XQQ1-BG83R

Single 256 GB DDR4 3200 ECC load-reduced LRDIMM for compatible Gigabyte servers and workstations

Capacity 256GB

  • Maximise server capacity with a single 256GB module
  • Error-correcting ECC load-reduced design protects data integrity
  • JEDEC-standard 3200MHz CL22 DDR4 at 1.2V
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems
  • Validated for Gigabyte E252-P30, E252-P31, G242-P31, G242-P32, G242-P33

Server-grade ECC LRDIMM

This OWC module is a single 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced DIMM built for workstations and servers. It targets Gigabyte E252-P30 E252-P31 G242-P31 G242-P32 G242-P33 platforms and similar qualified systems. JEDEC-standard and ROHS compliant, it provides error-correcting capacity for memory-intensive server workloads.

Not for desktops or mixed populations

The load-reduced ECC design will not operate in standard desktop motherboards and cannot be mixed with unbuffered or registered ECC DIMMs. Buyers who need consumer memory or who plan to combine different ECC types should select a different module. Compatibility is limited to validated server, workstation and NAS platforms that expressly support LRDIMM technology.

Sustained throughput at rated speed

Rated at 3200MHz CL22 with backward compatibility to 2133MHz 2400MHz 2666MHz and 2933MHz, the module maintains its specified latency and bandwidth under continuous multi-threaded server loads. The 1.2V operating voltage and 8Rx4 organisation are engineered for stability during extended operation rather than short benchmark bursts.

Questions about this item

Does my system need to support ECC load-reduced DDR4 and a 288-pin DIMM slot for this 256GB module to work?

Yes, the module requires a server or workstation platform that accepts ECC load-reduced DDR4 at 1.2V in a 288-pin slot; it will not work in standard desktop boards or with unbuffered or registered ECC memory.

Can I keep my existing 2133MHz, 2400MHz, 2666MHz or 2933MHz DDR4 modules installed alongside this 3200MHz CL22 LRDIMM?

The module is backward compatible with those speeds, but it cannot be mixed with unbuffered or registered ECC DIMMs; all slots must use the same load-reduced ECC type.

How can I confirm the 256GB LRDIMM is running at PC4-25600 3200MHz CL22 after installation?

Check the BIOS or UEFI memory information screen — it should report 3200MHz speed, CL22 latency, 1.2V voltage and ECC load-reduced status for the installed module.
