Exact-match DDR5 upgrade

This 64 GB DDR5-5600 registered ECC RDIMM is built to the Supermicro H14SHM memory controller's exact rank, voltage and timing requirements. It installs as a direct replacement so the server recognises the full capacity and runs at the rated PC5-44800 speed without manual tuning.

Thermals and power

Operating at 1.1 V, the module draws minimal power and generates little heat even when every slot is populated. The registered architecture buffers the control lines, keeping electrical loading low and allowing stable, quiet operation in densely packed server chassis.

Build integration

The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not seat in UDIMM or SODIMM slots. ECC corrects single-bit errors on the fly, preventing silent data corruption, while the registered design lets you fill all supported slots at full capacity. Verify your motherboard manual for approved population order before installation.

Questions about this item

How do I install the 288-pin RDIMM into the Supermicro H14SHM and which population rule do people miss?

Power down, open the chassis, and insert the module into the DIMM slot specified first in the motherboard manual — most builds skip that ordered-population step and the system will not POST with the 64 GB stick in the wrong slot.

What maintenance or replacement will this DDR5 ECC RDIMM need over its service life?

No scheduled maintenance is required; the registered ECC design corrects single-bit errors automatically, and the module is covered by a lifetime replacement warranty if a hardware fault ever develops.

What limit appears first when the 5600 MHz CL46 kit runs sustained workloads?

The registered buffer and 1.10 V operation keep every slot stable at the rated 5600 MT/s, so the practical ceiling is the motherboard's maximum supported capacity rather than a thermal or timing bottleneck.
