Exact-match DDR5-6400 ECC RDIMM kit for Supermicro

This 128GB kit contains two 64GB DDR5-6400 registered ECC RDIMMs built to the exact rank, voltage, and timing the Supermicro H13DSG-OM memory controller expects. It installs as a matched pair so the server recognises the full capacity and runs at the rated 6400 MT/s speed without manual tuning.

DDR5-6400 Registered ECC limits

The modules operate at 1.1V with CL52 latency in a 2Rx4 organisation, which the board's memory controller must support natively. Registered buffering allows every slot to be populated at full capacity, while on-die ECC corrects single-bit errors in flight. The 288-pin RDIMM form factor is physically incompatible with UDIMM or SODIMM slots, so the motherboard must provide registered DDR5 DIMM sockets.

Verify your Supermicro H13DSG-OM configuration

Consult the motherboard manual for the approved DIMM population order, maximum supported capacity per socket, and any BIOS version requirements before ordering. Server memory validation lists vary by specific model and firmware revision, so only the vendor's qualified-vendor list confirms that this exact 2Rx4 64GB RDIMM part number will initialise at 6400 MT/s in your chassis.

Questions about this item

Should I pick the 2x64GB kit or look for a different capacity for my Supermicro H13DSG-OM?

The kit supplies 128GB total as two 64GB modules. The H13DSG-OM requires registered ECC RDIMMs, and this exact 2Rx4 configuration matches the board's population rules for full-capacity operation.

What does DDR5-6400 actually deliver once the modules are installed in the server?

The memory controller will run the kit at 6400 MT/s (PC5-51200) with CL52 latency at 1.1V, giving the rated bandwidth and error-correcting stability the platform expects.

Is the 288-pin RDIMM interface the right one for the H13DSG-OM, and what does it cap?

Yes. The board only accepts 288-pin registered DDR5 RDIMMs; the registered buffer lets every slot run fully populated at the full 128GB kit capacity without signal degradation.
