768GB DDR5 4800 ECC RDIMM kit

This 768GB kit contains six 128GB DDR5 4800 CL40 registered DIMMs built for SuperMicro UP SuperServer SYS-111C-NR and SYS-521C-NR systems. It targets administrators who need maximum registered ECC capacity on the X13SEDW-F platform.

DDR5 4800 registered ECC limits

The modules run at DDR5 4800 (PC5-38400) with a CL40 latency and 1.10V operating voltage. Registered buffering and on-die ECC add command/address parity and single-bit correction, which are mandatory for the qualified SuperMicro servers but increase latency compared to unbuffered memory.

Six-module installation on X13SEDW-F

Populate all six 288-pin slots following the motherboard population guide; the 4Rx4 organisation requires the correct slot order to initialise at 4800 MT/s. Common issues include mixing ranks, skipping the registered DIMM requirement, or using an outdated BIOS that does not recognise the full 768GB capacity.

Preguntas sobre este artículo

How do I decide between a 128 GB module and a smaller capacity for my SuperMicro server?

Each module in this kit is 128 GB, giving 768 GB total across six slots; choose this capacity when your workload needs maximum density per DIMM slot.

What does the 4800 MT/s rating mean for actual throughput in a registered DDR5 system?

At DDR5 4800 the modules deliver PC5-38400 bandwidth, so sustained throughput is capped by that 38 400 MB/s ceiling in a compatible SuperMicro platform.

How does the 288-pin RDIMM interface limit memory speed on the X13SEDW-F motherboard?

The 288-pin registered DDR5 form factor locks the kit to 4800 MT/s on the X13SEDW-F, preventing higher speeds even if the CPU controller supports them.
