192GB DDR5 ECC RDIMM kit

This 192GB kit contains twelve 16GB registered DDR5 modules built for Supermicro FatTwin and SuperServer platforms. Each module runs at 4800 MT/s with CL40 latency and 1.10 V operation. The ECC RDIMM design targets enterprise workloads that require data integrity and high density.

Sustained enterprise workloads

Registered buffering and on-die ECC keep data paths stable during continuous database, virtualisation or HPC jobs. The 1Rx8 organisation allows full 192GB population without rank-related timing penalties. Modules are stress tested under load before shipping to verify long-run reliability.

Thermals and power at 1.10 V

Operating at the standard DDR5 voltage reduces per-module power draw compared with higher-speed bins. No heat spreaders are fitted, so airflow across the bare PCB handles cooling in dense 2U chassis. The lower voltage also limits waste heat during extended duty cycles.

Questions about this item

How much power will the 1.1 V DDR5 RDIMMs draw under continuous server load?

Each module runs at 1.1 V DDR5 standard voltage; total system draw depends on the platform memory controller and workload, not on the kit alone.

Which motherboard slots and CPU memory controllers are required for this 12 x 16 GB ECC registered kit?

The kit needs a Supermicro motherboard with twelve 288-pin DDR5 RDIMM slots and a CPU that supports registered ECC memory at 4800 MT/s.

Can I mix these 1Rx8 CL40 modules with existing 2Rx8 DDR5 RDIMMs in the same Supermicro system?

Mixing ranks is possible if the motherboard and BIOS support the combined population; check the system manual for approved rank configurations per channel.
