384GB DDR5 ECC RDIMM Kit for Supermicro H14DSH

This 384GB kit contains twelve 32GB DDR5 5600MHz registered ECC modules built to the exact rank, voltage and timing the H14DSH memory controller expects. It targets administrators who need maximum supported capacity in a single validated package.

Sustained Load Behaviour

Registered architecture offloads the memory controller so every slot runs fully populated at the rated 5600MHz speed without downclocking. ECC corrects single-bit errors on the fly, preventing silent data corruption during continuous enterprise workloads.

Installation and Common Issues

The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM boards will not accept these modules. Builders must follow the motherboard manual for approved population order and maximum capacity per channel to avoid POST failures.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the server runs continuously?

Each module operates at 1.1V, the standard DDR5 voltage, so total draw scales with the 12 installed DIMMs and the CPU memory-controller load.

What motherboard slot type and population rules must the H14DSH already have for this 12-DIMM kit to function?

The board needs 12 DDR5 288-pin RDIMM slots and must support 2Rx8 registered ECC population per the Supermicro manual.

Will the CL46 5600MHz registered ECC modules run at rated speed on an older Supermicro platform that only supports DDR5 4800?

The kit is spec-matched for the H14DSH; on a platform limited to 4800 MT/s the modules will downclock to that speed while keeping ECC and registered operation.
