64GB DDR5 6400 ECC RDIMM for Supermicro H13DSG-OM

This 64GB DDR5-6400 (PC5-51200) registered ECC RDIMM is built to the exact rank, voltage and timing the Supermicro H13DSG-OM memory controller expects. The 2Rx4 organisation, 1.10V operation and CL52 latency allow the module to be recognised at full capacity and run at its rated speed. It targets administrators upgrading that specific motherboard.

2Rx4 Registered ECC with major OEM chips

The registered architecture buffers address and command signals so every slot can be fully populated without overloading the controller. On-die ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. Chips are sourced from Samsung, Micron or Hynix depending on production lot.

Check motherboard manual for population rules

Server memory support varies by model and BIOS revision. Consult the Supermicro H13DSG-OM manual for approved DIMM population order, maximum capacity per channel and any required installation sequence before ordering. This module is a 288-pin RDIMM; it will not fit UDIMM or SODIMM slots.

Questions about this item

Will the 2Rx4 rank configuration need any firmware update on the Supermicro H13DSG-OM later?

The module matches the board's required 2Rx4 registered layout, so the memory controller recognises it at full capacity without extra firmware steps.

What limit appears first when the 6400 MT/s CL52 modules run continuously at full load?

The CAS latency of 52 cycles at 6400 MT/s sets the timing ceiling; sustained throughput is bound by that rated latency figure.

How much heat and power does a 1.1 V 64 GB DDR5 RDIMM produce during all-day operation?

At the specified 1.1 V the module draws minimal power and runs without a heat spreader, so thermal output stays low even under constant load.
