576GB DDR5 ECC RDIMM Kit for Supermicro H14SST-G

This 12-module kit delivers 576GB of DDR5 5600 registered ECC memory built for the Supermicro H14SST-G motherboard. Each 48GB 2Rx8 DIMM runs at 1.1V with CL46 latency. The 288-pin RDIMM form factor matches the board's registered-memory requirement exactly.

Suits fully populated servers; not for UDIMM boards

Registered ECC RDIMMs are required for this platform, so the kit suits administrators filling all 12 slots on a supported Supermicro H14SST-G system. Builders whose boards accept only unbuffered UDIMMs or SODIMMs cannot use these modules.

12 x 48GB 2Rx8 Registered ECC at DDR5 5600

The decisive specification is the 12-piece 2Rx8 registered ECC configuration at DDR5 5600. The memory controller must support this exact rank structure, voltage, and speed to recognise the full 576GB capacity and operate at the rated frequency.

Questions about this item

Does the Supermicro H14SST-G need all 12 DDR5 RDIMM slots filled to run this 576GB kit at 5600MHz?

The kit contains 12 modules of 48GB each. The H14SST-G motherboard dictates the supported population order and maximum capacity per slot. Consult the board manual for the exact DIMM sequence required to recognise the full 576GB at DDR5-5600.

Can I mix these registered ECC RDIMMs with any existing unbuffered DDR5 UDIMMs already installed in the server?

No. Registered RDIMMs and unbuffered UDIMMs use different signalling and cannot operate together on the same memory controller. All slots must use the same registered ECC DDR5 type for the system to boot and run stably.

After installation, how do I confirm the kit is running at DDR5-5600 CL46 with ECC active?

Enter the system BIOS or UEFI and open the memory information screen. It should report 576GB total, 5600MT/s speed, CL46 latency, 1.1V voltage, and ECC enabled for each of the 12 installed RDIMMs.
