16GB DDR5 4800 ECC Registered RDIMM

This 16GB DDR5 4800 RDIMM delivers ECC registered operation for server platforms that require error correction and signal buffering. The single-rank 1Rx8 organisation uses Hynix chips at CL40 latency and 1.10V. It suits administrators building or expanding memory arrays in compatible rackmount or tower servers.

Verify DDR5 RDIMM slot availability

Before ordering, confirm the motherboard accepts DDR5 RDIMM modules and enables ECC registered operation in the BIOS. Registered DIMMs will not function in platforms that only support unbuffered memory, and mixing registered with unbuffered types is not supported. Check the system vendor’s qualified vendor list for this exact part number.

Sustained throughput at CL40

Under continuous load the registered buffer reduces electrical loading on the memory controller, helping maintain stable timing at DDR5 4800 speeds. ECC corrects single-bit errors in real time, preventing data corruption during long compute runs. The 1.10V operating voltage keeps power draw consistent across extended duty cycles.

Questions about this item

Does the 16GB DDR5 4800 RDIMM come as a single module or a kit?

The product is a single 16GB RDIMM module. No additional parts are included in the box.

What does the 1Rx8 rank and CL40 latency mean for my server configuration?

The 1Rx8 organisation places all 16GB on one rank per channel. CL40 is the CAS latency at the rated 4800 MT/s speed.

How does the 4800 MT/s speed translate to actual bandwidth in a live system?

At DDR5 4800 the peak transfer rate is 38400 MB/s per module. Real-world throughput depends on the CPU memory controller and channel population.
