  • 192GB capacity with twelve 16GB modules for maximum server memory density
  • DDR5 4800 speed rated at PC5-38400 for high-throughput workloads
  • Registered ECC design corrects single-bit errors and stabilises fully populated slots
  • CL40 latency at 1.1V matches the motherboard memory controller specifications
  • Verified compatibility with Supermicro H14DSG-O-CPU using 288-pin RDIMM form factor

Exact-match server upgrade

This 192GB kit contains twelve 16GB DDR5 4800 registered ECC RDIMMs built for the Supermicro H14DSG-O-CPU motherboard. The modules run at 1.10V with CL40 timing and a 1Rx8 organisation that matches the board's memory controller requirements. Each 288-pin DIMM is validated so the full capacity is recognised at rated speed without manual tuning.

Sustained enterprise stability

Registered buffering offloads the memory controller, allowing all twelve slots to stay fully populated at 4800 MT/s under continuous load. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads. The 1.1V operating voltage keeps power draw consistent across the full kit.

Dense population without spreaders

The bare-module design fits tight server DIMM spacing where tall heat spreaders would block adjacent slots or airflow. Twelve 288-pin RDIMMs fill every channel the H14DSG-O-CPU supports, maximising capacity per CPU socket. Builders needing fewer modules or consumer UDIMM form factors should look elsewhere.

Questions about this item

How much heat does the 1.1V DDR5 4800 kit generate when all twelve 16GB RDIMMs run continuously?

Each module operates at 1.1V with no heat spreader, so airflow across the 288-pin RDIMMs is the primary cooling path; the registered buffer reduces electrical load on the memory controller, helping keep per-DIMM thermals steady under sustained load.

What motherboard and memory population rules must I already have for this 192GB kit to function?

A Supermicro H14DSG-O-CPU motherboard with twelve DDR5 RDIMM slots and a CPU that supports 1Rx8 registered ECC at DDR5 4800; the manual’s population order must allow all twelve slots to be filled simultaneously.

Can I mix these CL40 1Rx8 RDIMMs with older DDR5 ECC modules already installed in the same server?

Mixing ranks, latencies or voltages is not supported; the board expects identical 1Rx8 CL40 1.1V registered DIMMs in every populated channel, so older modules with different specs would prevent the kit from running at its rated speed.
