  • 16 GB registered ECC kit runs at full 3200 MHz on Supermicro X12SPT boards
  • 288-pin RDIMM form factor matches the motherboard's required slot type exactly
  • Registered architecture offloads the memory controller for stable full-population operation
  • ECC corrects single-bit errors on the fly to prevent silent data corruption
  • Built with major OEM chips from Samsung Micron or Hynix for enterprise reliability

Capacity and fit

This 16 GB kit contains two 8 GB DDR4 Registered ECC RDIMMs built for the Supermicro X12SPT-G and X12SPT-GC motherboards. The 288-pin registered form factor matches the board's required DIMM type exactly.

DDR4 3200 practical limits

Operating at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V, the modules run at the speed the platform's memory controller defines. Registered buffering lets every supported slot run fully populated without down-clocking, while ECC corrects single-bit errors before they reach the OS.

Build and daily implications

Major-brand DRAM from Samsung, Micron or Hynix ships without heat spreaders, relying on server chassis airflow. The 1Rx8 rank layout follows the motherboard's population rules, so installers must follow the manual's slot order to achieve the full 16 GB at rated speed.

Questions about this item

Should I choose the 2x8GB kit or a single 16GB module for my Supermicro X12SPT-G?

The kit provides two 8GB RDIMMs so the board can run dual-channel; a single 16GB stick would leave the second channel empty and halve memory bandwidth.

What does the DDR4 3200 PC4-25600 rating deliver on this motherboard?

The modules run at 3200 MT/s with CL22 timing at 1.20V, giving the maximum throughput the X12SPT-G memory controller supports when all slots are populated.

How does the 288-pin Registered ECC interface affect stability and capacity?

Registered buffering reduces electrical load on the controller so every slot can be filled at full speed, while ECC corrects single-bit errors to prevent silent data corruption.
