Server memory kit

This 1 TB kit contains eight 128 GB DDR5 4800 registered ECC modules built for SuperMicro X13SET-G and X13SET-GC motherboards. The 288-pin RDIMM design with 4Rx4 organisation targets enterprise servers and workstations that require high-density, error-correcting memory.

Sustained workload behaviour

Rated at CL40 and 1.1 V, the modules maintain JEDEC-standard DDR5 4800 throughput under continuous load. Registered buffering and on-die ECC preserve data integrity during extended compute, virtualization or database tasks without relying on overclocked profiles.

Thermals and power

Operating at the standard 1.10 V DDR5 voltage, the kit draws minimal power per module while running without heat spreaders. Bare-DIMM cooling relies on chassis airflow; registered buffers add negligible latency and keep signal integrity stable in densely populated slots.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the server runs continuously?

Each module operates at 1.1V; total system power depends on the platform and workload, so consult the motherboard documentation for full-load figures.

Which motherboard slots and CPU memory channels are required for the 8-module 1TB kit?

The kit is validated for SuperMicro X13SET-G and X13SET-GC motherboards; populate all eight 288-pin DDR5 RDIMM slots according to the board manual.

Can the 4Rx4 registered DDR5 modules share a channel with older DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds on the same channel is not recommended; use identical 4Rx4 DDR5-4800 modules for stable operation.
