768GB DDR5-5600 ECC RDIMM kit for Supermicro H13DSH

This 12-module kit delivers 768GB of DDR5 registered ECC memory built for the Supermicro H13DSH motherboard. Each 64GB module runs at 5600MHz with CL46 latency at 1.1V. The 2Rx4 registered design matches the board's memory controller requirements for full-capacity operation.

DDR5 RDIMM population rules limit total capacity

The H13DSH motherboard dictates how many registered DIMMs it can accept and in which sequence they must be installed. Filling all slots with 2Rx4 modules reaches the platform's maximum supported density only when the manual's population table is followed exactly. Deviating from the approved order can prevent the system from posting or reduce usable memory.

2Rx4 registered ECC at 1.1V decides compatibility

The memory controller expects registered modules with 2Rx4 organisation, ECC enabled, and a 1.1V operating voltage. UDIMMs, SODIMMs, or modules with different rank structure or voltage will not be recognised at full speed or capacity. Verify the motherboard manual for supported capacities and population rules before purchase.

Questions about this item

Should I choose the 12-module 768 GB kit or a smaller capacity for the Supermicro H13DSH?

The 12 x 64 GB kit fills every DIMM slot on the H13DSH, delivering the maximum 768 GB the board supports at the rated DDR5 5600 speed.

What does the DDR5 5600 rating mean once the modules are installed in the server?

The memory controller will run the kit at 5600 MT/s with CL46 latency at 1.1 V, providing the full PC5-44800 bandwidth the platform expects.

How does the 288-pin RDIMM interface affect real-world capacity limits on this motherboard?

The registered 288-pin RDIMM design lets the H13DSH address all 12 slots at full 64 GB per module without signal degradation, enabling the full 768 GB configuration.
