16 GB DDR5 ECC RDIMM for Supermicro

This 16 GB DDR5 4800 registered DIMM adds error-correcting memory to compatible Supermicro servers and workstations. It operates at 1.1 V with a CAS latency of CL40. The module uses a 1Rx8 organisation and major-brand DRAM chips from Samsung, Micron or Hynix.

Registered ECC with 288-pin DDR5 interface

The single decisive specification is the registered ECC RDIMM format on a 288-pin DDR5 interface. Systems that require unbuffered non-ECC UDIMMs or a different DDR generation cannot use this module. The PC5-38400 speed rating and CL40 timing are fixed by the SPD profile.

Fits Supermicro DDR5 RDIMM slots

Installation requires an available DDR5 RDIMM slot on a supported Supermicro motherboard. The registered buffer reduces electrical load on the memory controller, freeing the platform to populate more slots per channel. No heat spreader is fitted, so airflow across the bare PCB must be provided by the chassis.

Questions about this item

What does the 4800 MT/s speed mean once the module is installed in a compatible Supermicro system?

The module runs at 4800 MT/s, delivering PC5-38400 bandwidth when the motherboard and processor support DDR5 4800 operation.

How does the DDR5 RDIMM interface and CL40 latency affect real-world throughput?

Registered DDR5 with CL40 timing provides error-correcting, buffered operation; the CAS latency of 40 cycles is the access delay at the rated 4800 MT/s data rate.

What physical slot and clearance does this 288-pin 1Rx8 module require?

It fits a standard 288-pin DDR5 RDIMM slot and has no heat spreader, so it needs only the normal DIMM height clearance in the server chassis.
