Exact-Match DDR4 Kit for Supermicro X12SPA-TF

This 32 GB kit delivers two 16 GB DDR4-3200 RDIMMs tuned to the Supermicro X12SPA-TF motherboard. Registered ECC operation meets the board's memory-controller requirements for full-capacity recognition at rated speed. The 1Rx8 organisation and CL22 timing match the platform's qualified specification precisely.

Registered Architecture and 288-Pin Form Factor

Registered buffering reduces electrical load on the memory controller so every populated slot runs at full capacity. ECC circuitry corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor fits only boards that require registered modules, not UDIMM or SODIMM slots.

Low-Voltage Operation at 1.2 V

Modules run at 1.20 V without a heat spreader, keeping power draw modest in densely populated servers. Passive cooling relies on chassis airflow, so fan noise stays at the system's baseline level. The kit draws only the power needed for DDR4-3200 registered operation under normal workloads.
