Exact-fit DDR5 RDIMM for Supermicro H13DSG-OM

This 16 GB registered ECC module runs at DDR5 6400 with CL52 timing at 1.1 V. The 288-pin RDIMM form factor matches the motherboard's memory-population rules so the controller recognises full capacity immediately. It is built for servers that require registered architecture and error correction.

Sustained enterprise stability under load

Registered buffering offloads the memory controller, allowing every populated slot to run at rated speed continuously. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The fixed 1Rx8 organisation keeps timing predictable across all ranks.

Thermals noise and power in normal use

Operating at 1.1 V reduces power draw compared with higher-voltage DDR5 modules. No heat spreader is fitted, so airflow across the bare PCB handles cooling in standard server chassis. The module produces no audible noise and adds minimal thermal load to the system.

Questions about this item

How much heat does the 1.1V DDR5 RDIMM generate when the server runs continuously?

Operating at 1.1V, the 16GB DDR5-6400 registered module draws minimal power, keeping thermal output low even under sustained all-day workloads in fully populated Supermicro H13DSG-OM slots.

What motherboard slot and population rules must my system already have for this 288-pin RDIMM to work?

Your Supermicro H13DSG-OM must provide DDR5 RDIMM slots and follow its documented population order; the module is a 288-pin registered ECC DIMM that only fits and runs at rated speed in that exact configuration.

Will this CL52 registered ECC module run reliably alongside older DDR5 RDIMMs already installed in my Supermicro board?

Mixing ranks, latencies or voltages can prevent full-speed operation; for stable all-day use the board should use identical 1Rx8 1.1V CL52 registered ECC DIMMs in the approved population sequence.
