Exact-Match Server Upgrade

This 32 GB DDR4-3200 RDIMM delivers the precise 2Rx8 registered ECC configuration that the Supermicro X12SPA-TF memory controller expects. It operates at 1.2 V with CL22 timing so the module is recognised at full capacity and runs at its rated PC4-25600 speed without manual tuning.

Build Integration Requirements

The 288-pin registered form factor is mandatory for this motherboard; unbuffered UDIMMs or SODIMMs will not function. Registered architecture offloads the memory controller, allowing every slot to be fully populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Capacity and Headroom

A single 32 GB module provides substantial headroom for virtualisation hosts, database workloads and multi-tenant containers that demand registered ECC stability. Workloads requiring more memory per channel or higher frequencies than DDR4-3200 will exceed this module's specifications.

Questions about this item

Will the CL22 latency limit sustained throughput on my Supermicro X12SPA-TF?

CL22 is the rated timing for this DDR4 3200 module; the memory controller runs it at that latency when fully populated, so it does not impose an extra bottleneck beyond the JEDEC spec.

How much heat or power does this 1.2 V registered ECC DIMM add during all-day server loads?

At 1.2 V the module draws standard DDR4 registered power; with no heat spreader it relies on chassis airflow, which is typical for RDIMMs in 1U and 2U Supermicro systems.

What motherboard slot and population rules must my X12SPA-TF already support for this 2Rx8 288-pin kit to work?

The board needs a free 288-pin DDR4 RDIMM slot and must allow 2Rx8 registered DIMMs in the population order shown in the Supermicro manual for full 32 GB recognition.
