  • 2 TB total capacity lets you fully populate 16 slots with 128 GB modules
  • DDR5-4800 speed and CL40 latency match the board's rated timing for stable throughput
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation and 2Rx4 rank layout meet the exact electrical spec the server expects
  • 288-pin RDIMM form factor fits the Supermicro H14DSG-OM memory sockets without adapters

Exact-match DDR5 kit for Supermicro H14DSG-OM

This 2 TB kit contains sixteen 128 GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. It is intended for administrators upgrading that specific Supermicro platform to its full memory capacity.

DDR5 RDIMM population rules apply

Registered DIMMs let the memory controller drive every slot at rated speed, but the board’s manual dictates which sockets must be filled first and the maximum capacity per channel. ECC corrects single-bit errors automatically, yet total capacity and population order remain constrained by the platform firmware.

Sixteen 128 GB modules fill every slot

The kit delivers 2 TB only when all sixteen DIMM sockets are occupied with these 2Rx4 modules. Systems with fewer slots or a lower per-channel limit cannot use the full kit, so verify the motherboard’s supported configuration before purchase.

Questions about this item

Should I choose the 16-module 2 TB kit or a smaller kit for my Supermicro H14DSG-OM?

The 16 x 128 GB kit fills every slot on the H14DSG-OM and delivers the full 2 TB capacity the board supports; select a smaller kit only if you need fewer populated slots.

What does the 4800 MT/s rating mean once the modules are installed in the server?

The DDR5-4800 (PC5-38400) speed runs at the rated 4800 MT/s with CL40 latency at 1.10 V, giving the memory controller the exact timing it expects for full-capacity operation.

How does the 288-pin RDIMM interface limit what I can install?

The board requires 288-pin Registered DDR5 RDIMMs; UDIMM or SODIMM modules will not fit and cannot be used in this system.
