Supermicro H14DSG-OM DDR5 kit

This 256 GB kit contains two 128 GB DDR5-5600 RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. Registered ECC architecture keeps every slot stable at full population while correcting single-bit errors before they affect production workloads.

Verify manual before ordering

Consult the motherboard manual for supported capacities, approved DIMM population order and installation steps because server memory support varies by model. The board requires 288-pin Registered RDIMMs, not UDIMM or SODIMM form factors, and the kit matches that requirement.

Replaces mixed or slower RDIMMs

Swapping mismatched or lower-speed modules for this matched 2Rx4 CL46 kit restores full-channel bandwidth at 5600 MT/s and eliminates timing conflicts that cause silent corruption or unexpected reboots. The upgrade is worth it when capacity must scale to 256 GB without sacrificing ECC protection or registered stability.

Questions about this item

Does the 256 GB kit ship as two 128 GB modules or do I need to buy extra DIMMs?

The kit contains two 128 GB DDR5 RDIMMs, giving 256 GB total. No additional modules are required for that capacity.

Should I choose the 2Rx4 CL46 1.1 V version or a different rank and latency for the Supermicro H14DSG-OM?

This 2Rx4 CL46 1.10 V kit matches the board's qualified memory profile, so it will be recognised at full speed without manual tuning.

Will the DDR5-5600 rating actually run at 5600 MT/s once installed in the H14DSG-OM?

Yes, the modules are spec-matched to the motherboard's memory controller and will operate at the rated DDR5-5600 (PC5-44800) speed when populated per the manual.
