768GB DDR5-6400 ECC RDIMM Kit for Supermicro

This 16-module kit delivers 768GB of DDR5 6400 registered ECC memory built for the Supermicro H13DSG-OM motherboard. Each 48GB module runs at 1.1V with CL52 latency and a 2Rx8 organization. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at rated speed. It targets administrators scaling memory-intensive workloads on this specific platform.

288-Pin Registered Form Factor with Major OEM Chips

Modules use a 288-pin RDIMM form factor with no heat spreader, relying on server chassis airflow for cooling. Registered buffering offloads the memory controller, allowing all slots to run fully populated at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Chips are sourced from major OEM suppliers including Samsung, Micron and Hynix.

Verify DIMM Population Rules

Server and motherboard memory support varies by model. Consult the Supermicro H13DSG-OM manual for approved DIMM population order, maximum supported capacity per slot and installation steps. The kit provides 16 modules; your board must support this quantity and the 48GB density per DIMM. Confirm BIOS version requirements for DDR5 6400 operation.

Questions about this item

What does the DDR5 6400 PC5-51200 rating mean for real-world throughput?

The kit runs at 6400 MT/s, delivering up to 51200 MB/s per module; the memory controller on the Supermicro H13DSG-OM will operate all sixteen slots at this speed when populated per the board's validated sequence.

Will these 288-pin RDIMMs physically seat in the Supermicro H13DSG-OM DIMM slots?

Yes, the 288-pin registered form factor matches the board's DDR5 RDIMM slots exactly; UDIMM or SODIMM modules would not fit.

What population order does the H13DSG-OM manual require for a full 16-module install?

Install the sixteen 48 GB modules following the motherboard's prescribed slot sequence — typically filling channels symmetrically across both CPU sockets — so the BIOS recognises the full 768 GB at 6400 MT/s.
