Exact-fit 64 GB DDR4-3200 ECC kit

This 64 GB kit contains four 16 GB DDR4-3200 UDIMM modules rated at PC4-25600 with CL22 latency and 1.20 V operation. Each module is a 288-pin unbuffered ECC DIMM built with 1Rx8 organisation using major-brand Samsung, Micron or Hynix chips. The kit is validated for Supermicro X12STE-F and X12STD-F motherboards.

Suited for ECC workstations

Builders populating Supermicro X12STE-F or X12STD-F boards with the exact rank, voltage and timing the memory controller expects will get full-capacity recognition at rated speed. Systems that require registered RDIMMs, SODIMM form factors, non-ECC memory or capacities beyond 64 GB cannot use this kit.

Steady ECC correction under sustained load

Error-correcting code detects and corrects single-bit errors continuously, preventing silent data corruption during long compute runs. Unbuffered topology keeps latency low at CL22 while the 1.20 V supply maintains stable operation without extra cooling. The 1Rx8 rank layout follows the board's population rules for consistent throughput over extended sessions.

Highlights

  • Error-correcting code protects data integrity

  • 3200 MT/s DDR4 speed with CL22 latency
  • 2 V low-voltage operation reduces power draw
  • Verified fit for Supermicro X12STE-F and X12STD-F motherboards

Questions about this item

My Supermicro X12STE-F currently has empty DDR4 slots — do I need any other components for this 64 GB (4×16 GB) kit to work?

The motherboard and a compatible CPU are required; the kit itself contains four 288-pin DDR4-3200 ECC UDIMMs that plug directly into the board's memory slots with no extra hardware.

If I keep two 16 GB DDR4-3200 ECC UDIMMs already installed, will this 1Rx8 CL22 kit operate correctly in the remaining slots?

The board's memory-population rules determine whether mixed ranks and capacities are allowed; consult the Supermicro manual for the approved DIMM order before adding this 4×16 GB kit alongside existing modules.

After installing all four modules, how can I confirm the system is running the full 64 GB at DDR4-3200 with ECC active?

Check the BIOS memory information screen or the operating system's memory report — both should show 64 GB total, 3200 MT/s speed, and ECC enabled.
