Server-grade ECC memory for Supermicro platforms

This 128GB DDR5 module operates at 5600MHz with CL46 latency and 1.1V voltage. It is built as a 288-pin ECC registered RDIMM using a 4Rx4 organisation. The specification targets workstations, servers, NAS systems and network switches that require registered memory with error correction.

Single-module capacity simplifies slot planning

The upgrade arrives as one 128GB stick rather than a multi-module kit. This lets administrators fill a single DIMM slot to reach high density, leaving remaining slots open for future expansion. JEDEC and RoHS compliance ensures the module meets industry electrical and environmental standards.

Registered design dictates platform compatibility

Because the DIMM is registered and carries ECC, it will not work in standard desktop motherboards or alongside unbuffered or load-reduced memory. The 288-pin form factor fits DDR5 server boards such as the listed Supermicro models, but the registered buffer prevents use in consumer platforms that expect unbuffered modules.

Perguntas sobre este artigo

Will the 4Rx4 ECC registered DIMM need any firmware updates or battery-backed components replaced during its service life?

The module has no heat spreader and no onboard battery; it relies on the server platform for thermal management and configuration, so no user-serviceable firmware or battery replacement is required.

What is the first thermal or electrical limit reached when this 128 GB DDR5 5600 CL46 4Rx4 RDIMM runs at full load continuously?

Operating at 1.1 V with a CL46 latency, the rank density and registered buffer typically hit the platform's memory-controller thermal envelope before the DIMM itself exceeds JEDEC limits.

How much power does the 288-pin 1.1 V registered ECC module draw and how loud is the cooling when the server runs all day?

At 1.1 V the DIMM draws only the standard DDR5 registered power budget; it has no fan, so any audible noise comes from the chassis fans responding to the combined system heat load.
