768 GB DDR5-5600 ECC RDIMM kit for Supermicro H14SHM

This 12-module kit delivers 768 GB of registered DDR5 memory built to the exact timing and voltage the Supermicro H14SHM memory controller expects. Each 64 GB DIMM runs at 5600 MT/s with CL46 latency at 1.1 V using a 2Rx4 organisation. The 288-pin RDIMM form factor matches the board's registered-memory requirement so the system recognises the full capacity at rated speed.

Registered buffering and low-voltage operation

The registered architecture buffers address and command signals, reducing electrical load on the memory controller when all twelve slots are populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. Operating at 1.1 V keeps power draw low for a fully populated server configuration.

Lifetime replacement warranty

The kit ships as a matched 12-piece set with no heat spreaders, ready for installation following the motherboard's population rules. A lifetime replacement warranty covers the modules, and free US-based technical support is available to verify fitment or troubleshoot configuration questions before and after installation.

Questions about this item

How do I install the 12 DDR5 RDIMMs in the Supermicro H14SHM and what step is often missed?

Populate all 12 slots following the motherboard manual's exact DIMM population order; the step most people miss is verifying the approved sequence before inserting the 2Rx4 registered modules.

What maintenance or replacement will the 768GB DDR5 ECC RDIMM kit need over time?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers it, otherwise the registered ECC DDR5 memory runs without user-serviceable parts.

What limit appears first when the 12x64GB DDR5-5600 kit runs sustained workloads?

The memory controller's maximum supported capacity and population rules are the first limit; the 2Rx4 registered DDR5 modules operate at 1.1V CL46 within those constraints.
