512GB DDR5 ECC RDIMM kit for Supermicro servers

This 512GB kit contains four 128GB DDR5 5600 registered DIMMs built for Supermicro MBD-X13DGU AI SuperServer motherboards. Each module runs at 1.1V with CL46 latency and 4Rx4 organisation. The ECC registered design targets enterprise workloads that demand data integrity and high capacity.

Registered DDR5 5600 requires platform support

The DDR5 5600 PC5-44800 standard used here only functions on motherboards that accept registered ECC modules and can drive 1.1V at the rated speed. Consumer desktop chipsets and unbuffered DIMM slots will not recognise these sticks. Maximum throughput is limited by the memory controller and BIOS implementation on the host board.

Verify your Supermicro board accepts 4Rx4 128GB

Before ordering, confirm the specific motherboard revision and BIOS version support four ranks per module at the full 5600 MT/s data rate. Some server platforms cap registered DIMM speed when all slots are populated or when using 4Rx4 density. Check the vendor qualified vendor list for the exact part number MR44800-744K4.

Questions about this item

Should I choose the 4x128GB kit or a different capacity for my SuperMicro MBD-X13DGU?

The 4x128GB kit provides 512GB total across four 288-pin DDR5 RDIMM slots; each module is a 128GB 4Rx4 registered DIMM running at 1.1V.

What does the 5600 MT/s rating deliver when installed in the server?

The modules operate at DDR5 5600 (PC5-44800) with CL46 latency; actual throughput depends on the motherboard memory controller and populated channels.

How does the DDR5 RDIMM interface and ECC registration affect compatibility?

These are 288-pin DDR5 RDIMMs with ECC and registered buffering; they require a server platform that supports registered ECC DDR5 and will not fit consumer boards.
