System-specific DDR4 kit for Supermicro workstations

This 64 GB kit contains four 16 GB unbuffered UDIMMs rated at DDR4 2933 MT/s with CL21 latency and 1.20 V operation. It is built for Supermicro SuperWorkstation platforms such as the 5039AD-I and motherboards including the MBD-C9X299-PGF and CSE-GS5A-754K.

Verify motherboard slot count

Your board must accept four 288-pin DDR4 UDIMMs and support a total of 64 GB of non-ECC memory. Confirm the firmware revision allows 1Rx8 modules at 2933 MT/s without manual timing changes. The kit has no heat spreader, so ensure case airflow reaches the DIMM area.

Modules are stress-tested under sustained load

Each stick undergoes extended burn-in at rated speed and voltage to validate signal integrity during continuous workloads. The 1Rx8 organisation and major OEM DRAM from Samsung, Micron or Hynix maintain consistent throughput in multi-threaded server tasks without throttling.
