8GB DDR4 3200 ECC UDIMM CL22 single-rank module for SuperMicro B3ST1-CPU-001 systems
This 8GB DDR4 3200 ECC unbuffered UDIMM is validated for the SuperMicro B3ST1-CPU-001 motherboard. It targets IT professionals and system builders who need error-correcting memory for stable server or workstation operation. The module uses major OEM chips from Samsung, Micron or Hynix and runs at 1.20V. Buyers requiring registered DIMMs or non-ECC memory for consumer platforms should look elsewhere.
The stick installs into a standard 288-pin DDR4 slot and presents a single 1Rx8 rank at CL22 latency. Its unbuffered design connects directly to the memory controller without a register, so the board must support unbuffered ECC UDIMMs. No heat spreader is fitted, leaving the DRAM exposed for tighter clearances in dense chassis. Systems that require registered memory, load-reduced DIMMs or higher-capacity ranks cannot use this module.
The package contains one 8GB UDIMM only; no additional sticks, cables, software licences or mounting hardware are included. Installation is a manual DIMM swap following the motherboard manual. Because no extra components are bundled, the purchase does not change cabling, cooling or firmware requirements beyond the memory slot itself. Buyers needing multi-module kits or pre-configured sets must source them separately.

The unbuffered UDIMM has no heat spreader, so case airflow must carry heat away during continuous operation.
At 1.2 V the module draws standard DDR4 power and adds no fan noise; thermal load depends on chassis cooling.
It is validated for Supermicro motherboards using the B3ST1-CPU-001 part number.
