128GB DDR5 ECC RDIMM kit for Supermicro servers

This 128GB kit contains four 32GB DDR5 4800 registered DIMMs built with ECC for error correction in mission-critical workloads. It is validated for SuperMicro X13SET-G and X13SET-GC motherboards. The 1Rx4 organisation and 1.1V operating voltage suit enterprise server and workstation platforms requiring registered memory.

Registered DDR5 at 1.1V with no heat spreader

Operating at the standard DDR5 4800 speed and 1.10V, these modules draw minimal power and run cool without a heat spreader. The registered buffer reduces electrical load on the memory controller, aiding signal integrity in fully populated four-DIMM configurations typical of the target Supermicro systems.

Four-module kit tested for compatibility

The package delivers four matched 32GB RDIMMs stress-tested under load to verify stability in the qualified Supermicro platforms. No additional software or accessories are included; the value is in the validated compatibility and the lifetime replacement guarantee backed by IT support staff.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the SuperMicro X13SET-G motherboard, and which step is often missed?

Align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that all 128GB are detected at 4800 MT/s; the step often missed is fully seating both clips on every module.

What maintenance or replacement will the 1Rx4 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; replacement is only needed if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What limit appears first when the 128GB kit runs sustained workloads at 1.1V?

The primary limit is the CL40 CAS latency at 4800 MT/s, which sets the minimum response time under continuous load; thermal throttling is unlikely because the 1.1V operating voltage keeps power draw low.
