OWC 64GB DDR4 3200 ECC Registered RDIMM 2Rx4 CL22 1.2V Gigabyte R181-Z91/Z92 R182-340/34A/M80

64GB DDR4 3200 ECC Registered Module

This 64GB DDR4 3200 ECC Registered RDIMM is built for Gigabyte R181-Z91, R181-Z92, R182-340, R182-34A and R182-M80 servers and workstations. It delivers 64GB of error-correcting capacity in a single 288-pin module. The 2Rx4 organisation and CL22 timing suit memory-intensive workloads where data integrity matters. It is not compatible with standard desktop boards or unbuffered memory configurations.

Single DIMM Upgrade for Listed Gigabyte Platforms

The module plugs directly into a 288-pin DDR4 RDIMM slot on the supported Gigabyte systems. Registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel. Backward compatibility with 2133, 2400, 2666 and 2933MHz buses lets it slot into existing deployments without a full platform refresh. It cannot be mixed with unbuffered or load-reduced DIMMs.

1.2V Operation with No Heat Spreader

Rated at 1.2V, the module runs at standard DDR4 voltage for registered server memory. The absence of a heat spreader keeps the profile low for dense chassis layouts, relying on system airflow for cooling. JEDEC and RoHS compliance ensures consistent thermal behaviour within spec. Power draw scales with bus speed and population density in the host platform.
