Server-grade DDR5 upgrade

This OWC 128GB DDR5 5600 CL46 ECC registered DIMM is built for Supermicro SuperServer platforms including the SYS-421GE-TNHR2-LCC SYS-421GE-TNRT SYS-421GE-TNRT3 and SYS-421GU-TNXR. It targets administrators expanding memory capacity in workstations NAS systems and network switches that require registered error-correcting modules. The single-module design simplifies slot population in dense server chassis.

Thermals and power draw

Operating at 1.1V the module follows JEDEC DDR5 voltage standards for lower power consumption per gigabyte compared with previous generations. No heat spreader is fitted so airflow across the bare PCB handles thermal dissipation in typical server environments. Registered buffering reduces electrical load on the memory controller contributing to stable operation under sustained workloads.

Build and connectivity

The 288-pin RDIMM form factor with 4Rx4 organisation plugs directly into compatible Supermicro DDR5 slots without adapters. JEDEC and RoHS compliance ensures the module meets industry specifications for warranty-safe upgrades. ECC registered architecture prevents mixing with unbuffered or load-reduced DIMMs so identical modules must populate each channel for correct operation.

この商品に関する質問

How do I install the 288-pin DDR5 RDIMM in my Supermicro SuperServer SYS-421GE-TNHR2-LCC and which slot order is critical?

Power down, open the chassis, align the keyed 288-pin edge connector with the DDR5 slot notch, press firmly until both ejector clips click shut, then populate slots per the motherboard manual channel sequence for registered memory.

What maintenance or replacement will the 128GB 4Rx4 ECC registered module need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, but if correctable-error counters in the BMC log climb steadily, plan to replace the DIMM before uncorrectable faults appear.

What limit appears first when the 5600 CL46 1.1V RDIMM runs sustained workloads in a SYS-421GU-TNXR?

The registered buffer and on-die ECC add latency, so memory-controller throughput saturation typically arrives before thermal throttling at the standard 1.1 V operating point.
