Exact-match DDR5-4800 upgrade

This 64 GB kit provides two 32 GB DDR5-4800 registered ECC modules built for the Supermicro H13SST-GC motherboard. The 2Rx8 rank layout and 1.10 V voltage match the platform's memory controller so the system recognises the full capacity at rated speed.

Low-voltage registered operation

Running at 1.10 V with registered buffering reduces electrical load on the memory controller during normal server workloads. The absence of a heat spreader keeps the modules slim for dense DIMM populations while ECC corrects single-bit errors on the fly.

Sustained enterprise stability

Registered architecture allows every slot to stay fully populated at full capacity without signal degradation over long runs. ECC continues to catch and correct errors throughout extended compute tasks, preventing silent data corruption and unplanned reboots in production environments.

Questions about this item

How do I install the 288-pin RDIMM kit on the Supermicro H13SST-GC and what step is often missed?

Power down, open the chassis, and insert each module into the slots specified by the motherboard manual; the step most people miss is following the exact population order so the 2Rx8 registered DIMMs initialise at the rated DDR5 4800 speed.

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

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only necessary if a DIMM fails, which is covered by the lifetime replacement warranty.

What limit appears first when the 1.1V CL40 registered memory runs sustained workloads on this platform?

The registered buffer and ECC logic keep every slot stable at full 64GB capacity, so the first limit you encounter is the motherboard's maximum supported memory rather than a module-level constraint.
