Exact-Match Server Upgrade

This NEMIX RAM kit delivers 768GB across twelve 64GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. Registered ECC with 2Rx4 organisation provides the error correction and signal buffering required for continuous server workloads.

Build Integration

The 288-pin RDIMM form factor matches the Supermicro H13DSG-OM motherboard slots exactly, so no UDIMM or SODIMM alternatives will fit. Fully populating all twelve slots at rated speed depends on following the board's documented population order and maximum capacity rules.

Sustained Load Behaviour

Registered architecture reduces electrical load on the memory controller, allowing every slot to run fully populated without down-clocking during extended compute runs. ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise trigger unplanned reboots under heavy utilisation.

Questions about this item

Will the 1.1V voltage limit thermal headroom when all 12 slots run continuously?

Each module operates at 1.1V without a heat spreader, so sustained full-load temperatures depend on chassis airflow and DIMM spacing rather than the memory itself.

How much fan noise or extra cooling does a fully populated 768GB kit add?

The registered DDR5 RDIMMs have no integrated cooling, so any additional noise comes from server fans reacting to the 12 modules under load.

Does the Supermicro H13DSG-OM motherboard need a specific BIOS revision to recognise the full 768GB?

The kit is validated for the H13DSG-OM; the board manual lists the required DIMM population order and minimum firmware for 12 x 64GB 2Rx4 registered modules.
