Server-grade DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 registered DIMMs built for SuperMicro MBD-X13DGU AI SuperServer motherboards. It targets IT professionals and system integrators who need validated ECC memory for mission-critical server and AI workloads. The modules operate at 1.1V with CL46 latency and a 2Rx4 rank configuration.

DDR5 5600 registered memory limits

Registered DDR5 at 5600 MT/s requires a platform that supports PC5-44800 speeds and ECC error correction. The 288-pin RDIMM form factor and 2Rx4 organisation are only compatible with server chipsets that implement registered memory controllers. Consumer desktop boards cannot use these modules and will not boot with them installed.

Pre-installation compatibility checks

Confirm that the SuperMicro MBD-X13DGU motherboard BIOS revision supports 256GB total capacity across all eight slots with 2Rx4 registered DIMMs. Verify the system power delivery can sustain 1.1V operation for the full kit. Check the server documentation for any population rules that restrict rank mixing or maximum DIMMs per channel.

Questions about this item

Should I buy the 256GB kit or a smaller DDR5 ECC RDIMM set for my Supermicro motherboard?

This kit provides eight 32GB modules for a total of 256GB. Choose it if your Supermicro board supports eight DDR5 RDIMM slots and your workload needs that capacity.

What does the 5600 speed rating deliver in a running server?

The modules operate at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, giving the rated bandwidth and timing when the motherboard runs them at that speed.

How does the 288-pin DDR5 RDIMM interface affect installation and performance limits?

The 288-pin registered DIMM format fits DDR5 RDIMM slots only. The registered buffer and ECC function let the memory controller address all eight modules at the rated 5600 speed.
