Exact-match upgrade

This 16 GB DDR4 ECC UDIMM is built for the Supermicro X12STE-F and X12STD-F motherboards. It delivers the precise 1Rx8 rank, 1.2 V voltage and CL22 timing the memory controller expects. The module installs as a single 288-pin DIMM and runs at the rated 3200 MT/s speed without manual tuning.

Verified fitment

The unbuffered ECC form factor matches the board's 288-pin DDR4 slots and population rules, avoiding the RDIMM or SODIMM mismatch that would prevent boot. ECC circuitry detects and corrects single-bit errors on the fly, protecting data integrity in always-on workloads. Builders must still consult the motherboard manual for approved slot order and maximum capacity limits.

Sustained reliability

Major-brand Samsung, Micron or Hynix DRAM chips operate at the standard 1.2 V, keeping thermal output low during continuous operation. The CL22 latency remains stable across long compute sessions, and the lifetime replacement warranty backs the module for the system's service life. This kit is not suited for platforms that require registered memory or non-ECC operation.

Questions about this item

Does CL22 at 3200 MT/s create a latency bottleneck under sustained workloads?

CL22 is the rated CAS latency; the module runs at its specified 3200 MT/s timing without additional delay.

How much heat and power does a 1.2 V DDR4 ECC UDIMM produce during all-day operation?

The module operates at 1.20 V with no heat spreader; power draw stays within standard DDR4 limits for continuous use.

What motherboard slot and memory type must my system already have for this 288-pin UDIMM to work?

Your board needs a DDR4 288-pin UDIMM slot that supports unbuffered ECC memory.
