  • ECC protects data integrity by correcting single-bit errors on the fly
  • 32 GB kit (4 × 8 GB) fills four slots for full capacity
  • DDR4-3200 CL22 1.2 V matches the board's rated speed and timing
  • 288-pin unbuffered UDIMM form factor fits Supermicro X12STE-F / X12STD-F exactly
  • Major-brand Samsung, Micron or Hynix chips ensure consistent quality and compatibility

System-specific upgrade kit

This 32GB kit contains four 8GB DDR4 ECC UDIMM modules rated at 3200 MT/s with CL22 latency at 1.2V. It is built for Supermicro X12STE-F and X12STD-F motherboards that require unbuffered ECC memory in a 288-pin DIMM form factor.

Unbuffered ECC construction

Each module uses a 1Rx8 organisation with major-brand DRAM chips and no heat spreader, keeping the profile low for dense server chassis. The 288-pin UDIMM edge connector matches the board slots exactly, so installation follows the motherboard's standard population order without adapters or registered DIMM clearance issues.

DDR4 platform limits

The DDR4 interface tops out at the 3200 MT/s data rate and 1.2V operating point specified here, so the kit cannot exceed that bandwidth on this generation. Buyers who need higher memory density per slot or registered DIMM support for larger capacities will need a platform that moves beyond DDR4 unbuffered ECC.

Questions about this item

What DDR4 standard and speed does this 32GB kit use?

This kit uses DDR4 3200 (PC4-25600) with CL22 timing and 1.20V voltage.

What physical slot and form factor are required for these modules?

The modules are 288-pin unbuffered ECC UDIMMs; they need standard desktop DIMM slots that accept unbuffered ECC memory.

How should the four 8GB sticks be installed on a Supermicro X12STE-F or X12STD-F board?

Install all four modules following the motherboard manual's population order for 4 DIMMs; a common mistake is skipping the prescribed slot sequence, which can prevent full capacity recognition.
