Supermicro Certified 16GB DDR5 RDIMM

This 16GB DDR5 module carries Supermicro certification and uses Samsung chips in a registered 288-pin form factor. It runs at 4800MHz with CL40 latency and operates at the standard 1.10V DDR5 voltage. ECC registered functionality provides native error correction for server workloads.

For servers needing validated ECC memory

System builders maintaining Supermicro platforms that require certified DDR5 RDIMMs will find this module matches the qualified vendor list. Buyers who need non-ECC unbuffered DIMMs for consumer desktop boards should look at something else because this module is registered and requires a server chipset.

Simple installation with compatibility checks

Installation follows standard RDIMM procedure: align the key notch with the 288-pin slot and press until the latches engage. What usually goes wrong is mixing registered and unbuffered modules in the same channel or populating slots in an order the motherboard manual does not support.

Questions about this item

What motherboard slot is required for this 288-pin DDR5 RDIMM?

Your motherboard must provide a DDR5 RDIMM slot; the module uses a 288-pin DDR5 form factor that is not interchangeable with other generations.

Will this ECC RDIMM function in a system that currently uses non-ECC UDIMMs?

No, the registered ECC design requires a platform that supports registered memory and ECC; it cannot be mixed with unbuffered non-ECC modules.

How can I confirm the module is running at 4800 MT/s with CL40 after installation?

Check the BIOS or an OS tool such as CPU-Z; the memory should report DDR5-4800, PC5-38400 speed and CL40 timings at 1.1 V.
