Certified Supermicro DDR5 RDIMM

This 32 GB DDR5 4800 CL40 registered ECC module carries Supermicro certification for validated compatibility. It targets server administrators and workstation builders who require registered memory with native error correction. The single dual-rank stick adds capacity without mixing ranks.

Fits 288-pin RDIMM slots on qualified Supermicro

The module operates at the standard 1.1 V DDR5 voltage and uses a registered buffer to reduce electrical load on the memory controller. Its dual-rank 2Rx8 organisation increases density per slot, freeing additional DIMM positions for future expansion. Verify the system qualified-vendor list before installation.

Replaces unbuffered or lower-capacity DDR5 RDIMMs

The jump is worthwhile when workloads demand registered ECC integrity and a single 32 GB module simplifies population rules. Systems limited to unbuffered memory or requiring different rank configurations cannot use this module.

Questions about this item

How does the CL40 latency behave when the 32GB module runs at 4800 MT/s under continuous load?

The module operates at DDR5 4800 with a CL40 timing at 1.10V; sustained workloads stay within this rated latency envelope.

What thermal or acoustic impact should I expect from the 1.1V registered DIMM during all-day operation?

At the standard 1.1V DDR5 voltage the registered DIMM produces minimal extra heat and no audible noise in a properly ventilated server chassis.

Which motherboard slot and chipset features are required for this 288-pin 2Rx8 ECC RDIMM to function?

A DDR5 RDIMM slot with native ECC support and a platform qualified for 2Rx8 registered modules is required.
