128GB DDR5 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR5 4800 RDIMM modules built for servers and workstations that require registered ECC memory. Each module runs at 1.10V with a CL40 latency and a 1Rx8 organisation. The registered design helps signal integrity on heavily populated motherboards.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity stable during continuous workloads such as virtualisation, database serving or scientific compute. The 1.10V operating voltage limits thermal output per module, helping dense configurations maintain consistent throughput without throttling. Major OEM DRAM from Samsung, Micron or Hynix underpins long-term reliability.

Compatibility checklist

Verify that your motherboard supports DDR5 RDIMM modules at 4800 MT/s and can address 128GB across eight 288-pin slots. Confirm the platform accepts 1Rx8 registered ECC DIMMs and that the BIOS is current enough to initialise the full kit. No heat spreaders are fitted, so ensure airflow reaches the bare modules.

Questions about this item

How much power does the 128GB kit draw at its rated 1.10V DDR5 4800 speed?

Each 16GB module runs at 1.10V; total draw depends on the platform's memory controller and load, so consult the server manual for exact wattage.

What motherboard features are required to run this 8 x 16GB DDR5 4800 CL40 registered ECC kit?

A DDR5 RDIMM slot, registered ECC support, and a qualified memory controller that accepts 1Rx8 modules at PC5-38400.

Will these 288-pin DDR5 1Rx8 registered ECC modules work in a board that currently uses DDR5 UDIMMs?

No, registered RDIMMs and unbuffered UDIMMs are electrically different and cannot be mixed in the same system.
