384GB DDR5 4800 ECC RDIMM kit

This 384GB kit contains six 64GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for Supermicro SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms that require registered memory. Each module operates at 1.1V and uses a 2Rx4 organisation. The 288-pin form factor fits server motherboards designed for DDR5 RDIMMs.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, helping stability during continuous server workloads. ECC corrects single-bit errors and detects multi-bit errors to protect data integrity under sustained operation. The 1.1V operating voltage supports consistent throughput at the rated 4800 MT/s speed. Modules are stress tested under load by the supplier before shipping.

Compatibility checks before ordering

Verify that your Supermicro system lists DDR5 4800 RDIMM support and can accept 64GB dual-rank modules in all six slots. Confirm the motherboard BIOS version qualifies this capacity and rank configuration. Ensure the chassis provides enough DIMM slots for the full 6x64GB kit. Check that your workload benefits from registered ECC memory rather than unbuffered alternatives.

Questions sur cet article

How much heat and power does the 1.10V CL40 kit draw when running all day in a server?

Each 64 GB module operates at 1.10 V with CL40 timings; DDR5 RDIMMs at this voltage typically run cool enough for continuous 24/7 server loads without extra cooling.

What motherboard slots and CPU memory controllers are required for the 288-pin 2Rx4 registered DIMMs?

The kit needs a Supermicro motherboard with DDR5 RDIMM slots and a CPU that supports registered ECC memory; consumer boards with unbuffered slots will not work.

Can the six 64 GB sticks be mixed with smaller DDR5 ECC RDIMMs already installed in the same system?

Yes, provided the existing modules are also DDR5 4800 registered ECC RDIMMs; mixing ranks or speeds may force the channel to the slowest common timing.
