Server Memory Upgrade

This 128GB DDR5 5600 registered ECC module is built for the listed Supermicro SuperServer platforms. It targets administrators who need a single high-capacity DIMM to expand memory in compatible workstation or server chassis. The 4Rx4 organisation and 1.1V operation match the OEM specification for these systems.

Registered ECC Constraints

The module uses registered ECC DDR5 technology at PC5-44800 with CL46 latency. It will not function in standard desktop boards or in systems that require unbuffered or load-reduced DIMMs. Mixing this stick with non-registered memory is not supported and will prevent boot on the validated platforms.

Build and Installation

The bare 288-pin PCB has no heat spreader, relying on chassis airflow for thermal management. A single DIMM occupies one slot, leaving remaining channels available for identical modules to maintain matched ranks. JEDEC and ROHS compliance ensures the upgrade meets the original manufacturer specifications for the supported SuperServer models.

Questions about this item

Should I pick the 128GB DDR5 5600 CL46 4Rx4 RDIMM or a smaller capacity for my SuperServer?

The 128GB module fills one 288-pin slot with 4Rx4 organisation, giving maximum density per channel for the listed SuperServer models.

What does the 5600 MT/s rating deliver inside a Supermicro SYS-211E-FRN2T?

The module runs at the JEDEC DDR5 5600 standard with CL46 latency at 1.1V, providing the peak bandwidth the platform’s memory controller supports.

How does the DDR5 288-pin ECC Registered interface limit performance in practice?

The registered buffer adds one cycle of command latency, capping maximum frequency to the 5600 MT/s JEDEC spec while ensuring signal integrity across full server memory populations.
