  • 16GB DDR4 3200 CL22 registered ECC RDIMM runs at rated speed on Supermicro X12SPA-TF
  • Registered architecture offloads memory controller for full-capacity population across every slot
  • ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots
  • 2V operation with 1Rx8 rank matches board memory-controller expectations exactly
  • 288-pin RDIMM form factor fits the required slot type not UDIMM or SODIMM

Exact-match 16 GB DDR4-3200 RDIMM

This 16 GB DDR4-3200 (PC4-25600) registered ECC RDIMM is built for the Supermicro X12SPA-TF motherboard. It delivers the precise 1Rx8 rank, 1.2 V operating voltage and CL22 latency the board's memory controller expects. The 288-pin form factor ensures physical compatibility with the server's DIMM slots.

Sustained-load behaviour

Registered architecture offloads the memory controller so every populated slot runs at the rated 3200 MT/s without down-clocking under continuous demand. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs or virtualization workloads. The module maintains its specified timing throughout extended operation.

Thermals noise and power

Operating at 1.2 V keeps power draw low and heat output minimal inside dense server chassis. No heat spreader is fitted, relying on the system's directed airflow for cooling. The design adds no moving parts, so acoustic contribution is zero. Power consumption scales with the 16 GB capacity and registered buffer overhead.

Questions about this item

How much heat and power will the 1.20 V DDR4 RDIMM draw when the server runs continuously?

The module operates at 1.20 V with no heat spreader, so it relies on chassis airflow; registered buffering reduces electrical load on the memory controller during all-day operation.

What must my Supermicro X12SPA-TF motherboard already support for this 16 GB DDR4 3200 CL22 RDIMM to work?

The board needs a DDR4 3200 registered DIMM slot, ECC capability, and a population rule that accepts 1Rx8 288-pin modules at 1.20 V.

Can I keep my existing DDR4 RDIMMs and add this 1Rx8 CL22 stick without slowing the channel?

Mixing ranks or latencies forces the channel to the slowest common timing; check the manual for approved population order before combining with other DDR4 RDIMMs.
