OWC 128GB DDR4 3200 CL22 4Rx4 288-pin 1.2V ECC LRDIMM 3L2D44R4128G

128GB DDR4 ECC LRDIMM for Gigabyte Servers

This 128GB DDR4 3200 CL22 module targets administrators upgrading Gigabyte R182-N20, R182-NA0, R182-NA1, R182-NC0 or R182-P91 platforms. The load-reduced ECC design serves workstation and server workloads that demand error correction and high density per slot. It will not operate in standard desktop computers and cannot be mixed with unbuffered or registered ECC memory.

Sustained load behaviour at 3200MHz

Rated at DDR4 3200 (PC4-25600) with CAS latency 22 and 1.2V operation, the module maintains JEDEC-standard timing under continuous server workloads. Backward compatibility with 2133MHz, 2400MHz, 2666MHz and 2933MHz buses allows deployment in mixed-speed configurations without downclocking penalties. The 4Rx4 organisation distributes electrical load across ranks to stabilise signal integrity during extended compute tasks.

Build quality and daily implications

The 288-pin LRDIMM form factor fits server DIMM slots directly; no heat spreader is present, relying on chassis airflow for thermal management. JEDEC and RoHS compliance ensures warranty-safe installation in OEM environments. Micron MTA72ASS16G72LZ3G2, Samsung M386AAG40AM3-CWE and Hynix HMABAGL7ABR4N-XNT5 cross-references confirm interchangeability with existing fleets. Buyers needing non-ECC desktop memory or smaller capacities should look elsewhere.
