Capacity & Target System

This 128 GB kit uses four 32 GB DDR4 2933 UDIMM modules built for Supermicro workstations such as the 5039AD-I and MBD-C9X299-PGF. It suits IT professionals who need maximum non-ECC capacity on supported platforms. Unbuffered operation keeps latency low for memory-intensive workloads.

Sustained Load Behaviour

Modules run at 1.20 V with CL21 timings and 2Rx8 organisation, delivering steady throughput during long render or virtualisation sessions. Rigorous stress testing under load is performed before shipment to confirm stability. The major OEM Samsung, Micron or Hynix chips maintain consistent performance without thermal throttling.

Build & Daily Handling

Bare green PCBs without heat spreaders fit tight DIMM slots and simplify cleaning in dense server chassis. Each 288-pin UDIMM seats with standard keying for quick tool-free upgrades. Lifetime replacement coverage backs the hardware for the system's service life.

Questions sur cet article

Does the 1.2V DDR4 2933 kit add noticeable heat or fan noise when all four slots run all day?

These modules operate at the standard 1.20V DDR4 voltage and have no heat spreader, so thermal output is typical for unbuffered UDIMMs at this speed and density.

What must my motherboard provide for the 128GB (4x32GB) kit to function?

The board needs four 288-pin DDR4 UDIMM slots, support for 2Rx8 non-ECC unbuffered modules at 2933 MT/s, and a memory controller able to address 128GB total capacity.

Will the CL21 2Rx8 modules work alongside older DDR4 sticks I keep in the same system?

Mixing ranks, speeds or latencies can prevent the system from posting or force all memory to the lowest common settings; for stability, populate all four slots with this matched kit.
