16GB DDR5 4800 ECC RDIMM for SuperMicro servers

This registered DDR5 module delivers 16GB of error-correcting memory at 4800 MT/s with CL40 latency. It operates at 1.1V and uses a 1Rx8 organisation on a 288-pin form factor. The stick is built for SuperMicro platforms that require registered ECC memory.

No accessories or software included

The package contains only the single memory module. There are no heat spreaders, cables, drivers or management utilities supplied. Installation relies on the server firmware recognising the JEDEC-standard DDR5 timings and registered buffer.

Verify your motherboard supports DDR5 RDIMM ECC

Confirm the board accepts 288-pin registered DIMMs with ECC and can run at 4800 MT/s. Systems limited to UDIMM, non-ECC or earlier DDR generations will not work with this module. Check the qualified-vendor list for 1Rx8 16GB parts before ordering.

Questions about this item

Does the module require a heat spreader replacement for continuous server operation?

The module ships without a heat spreader, so no spreader maintenance or replacement is needed during its service life.

What limits sustained throughput at the rated 4800 MT/s speed?

The CL40 CAS latency and single-rank 1Rx8 organisation set the timing ceiling for continuous workloads at the rated speed.

How much heat does the 1.1 V registered DIMM produce under all-day load?

Operating at 1.10 V without a heat spreader, the registered DDR5 module runs cool enough for standard server airflow.
