Compatible DDR5 ECC RDIMM

This 16GB DDR5 4800 module is built for the SuperMicro SuperWorkstation SYS-751A-I and X13DAI-T platforms. It delivers registered ECC memory for workloads that demand data integrity and server-grade stability. The single-rank 1Rx8 design operates at 1.1V with CL40 latency.

Registered DDR5 for server boards

The 288-pin RDIMM format fits motherboards that require registered memory and will not accept unbuffered DIMMs. ECC circuitry corrects single-bit errors to protect critical data. No heat spreader is included, so airflow in the chassis must be adequate for sustained loads.

Upgrade from lower-capacity DDR5 RDIMMs

Adding this module increases total memory without mixing speeds or ranks. It suits users who need more capacity for virtualization or large datasets but do not require higher frequencies. Builders needing unbuffered memory or non-ECC modules should look elsewhere.

Questions about this item

What sustained-use limit appears first with this 1.10 V DDR5 4800 ECC RDIMM?

The module runs at 1.10 V with CL40 timings; under continuous load the first limit is the memory controller's thermal throttle point, not the DIMM itself, since there is no heat spreader.

How much heat and noise does this registered 1Rx8 module add when the server runs all day?

It draws 1.10 V at DDR5 4800 with no onboard fan or spreader, so heat is dissipated passively into the chassis airflow and it adds no audible noise of its own.

What must the system already provide for this 288-pin RDIMM to work?

A Supermicro motherboard with DDR5 RDIMM slots that support ECC registered memory at 4800 MT/s and 1.10 V operation.
