Exact-match server upgrade

This 768GB kit delivers twelve 64GB DDR5 RDIMM modules rated at 4800MHz PC5-38400 with CL40 timing and 1.1V operation. The 2Rx4 registered ECC design matches the Supermicro H13SSH motherboard requirements so the memory controller recognises full capacity at rated speed without manual tuning.

Thermals noise and power

Registered buffering reduces electrical load on the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The 1.1V DDR5 voltage keeps power draw low per module even with all slots populated.

Build integration and constraints

The 288-pin RDIMM form factor fits only motherboards that accept registered DDR5; it will not work in UDIMM or SODIMM slots. Buyers must consult the H13SSH manual for approved population order and maximum supported capacity before installation. Modules ship without heat spreaders so airflow across the PCB is required.

Questions about this item

How do I install the 12 DDR5 288-pin RDIMM modules in the Supermicro H13SSH, and which slot-population step is most often missed?

Follow the motherboard manual's exact DIMM population order; the step most often missed is filling the correct channel sequence for all 12 slots so the memory controller recognises the full 768 GB at DDR5-4800.

What maintenance or replacement will the 12 x 64 GB DDR5 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; if a module fails, the lifetime replacement warranty covers a direct swap of the defective 64 GB RDIMM.

What limit appears first when the 768 GB DDR5-4800 2Rx4 registered ECC kit runs sustained workloads on the H13SSH?

The memory controller's maximum supported capacity and rank-per-channel limit is reached first; the board's population rules cap usable DIMMs before thermal or voltage thresholds become a factor.
