Exact-match upgrade for Supermicro X12STE-F

This 8GB DDR4 3200 ECC UDIMM is built to the precise rank, voltage, and timing the board's memory controller expects. The 288-pin unbuffered form factor matches the motherboard's requirements exactly so the module is recognised at full capacity and runs at its rated speed. It is intended for administrators upgrading or repairing those specific Supermicro platforms.

Sustained reliability

ECC circuitry detects and corrects single-bit errors continuously during operation, preventing silent data corruption and unplanned reboots under prolonged workloads. The 1.2V operating voltage and CL22 latency remain stable across extended sessions because the module uses major OEM chips validated for server duty. No heat spreader is fitted, relying on chassis airflow for thermal management.

DDR4 platform limits define the practical ceiling

The DDR4 3200 (PC4-25600) interface sets the maximum bandwidth and latency floor this module can deliver regardless of workload intensity. Population rules in the motherboard manual dictate how many such DIMMs can be installed and in which slots, capping total system capacity. Builders needing higher densities or registered DIMM support must select a different memory type not provided by this kit.

Questions about this item

How much power does the 1.20 V DDR4 3200 module draw when the system runs all day?

At the rated 1.20 V the 8 GB stick operates within standard DDR4 power limits, and the unbuffered design avoids the extra current a registered DIMM would need.

What must the motherboard provide for this 288-pin ECC UDIMM to function?

The board needs a DDR4 slot that accepts unbuffered ECC UDIMMs and follows the Supermicro X12STE-F or X12STD-F population rules for 1Rx8 modules.

Will the CL22 1Rx8 stick run at its rated speed alongside slower DDR4 modules already installed in the same board?

The memory controller will clock all populated slots to the lowest common speed, so the 3200 MT/s module will downshift to match the slower DIMMs.
