128GB DDR4 2933 kit for Supermicro systems

This 128GB kit contains four 32GB DDR4 2933 UDIMM modules built for Supermicro desktop and workstation motherboards. It suits IT professionals and enthusiasts who need high-capacity, non-ECC memory for compatible Supermicro platforms. The modules run at 1.2V with CL21 latency and use major OEM chips from Samsung, Micron or Hynix.

DDR4 2933 speed and unbuffered design

The kit operates at the DDR4 2933 (PC4-23400) standard with 288-pin unbuffered UDIMM modules. Each module is a 2Rx8 rank configuration without ECC or a heat spreader. Performance is limited to the DDR4 2933 data rate and CL21 timing; the memory will not run at higher DDR4 speeds or support registered or load-reduced operation.

Check motherboard slots and maximum capacity

Verify that the target Supermicro motherboard accepts four 288-pin DDR4 UDIMM modules and supports 128GB total capacity at 2933 MT/s. Confirm the board does not require ECC or registered DIMMs, as this kit is non-ECC and unbuffered. Consult the system manual for approved memory configurations and population rules before ordering.

Questions about this item

Should I pick this 128GB kit of four 32GB modules or a smaller capacity for my Supermicro workstation?

Choose the 128GB kit if your board supports four UDIMM slots and you need maximum capacity for heavy workloads; each module is 32GB so the kit fills all four slots at once.

What does the 2933 MT/s rating actually deliver once the memory is installed in my system?

The modules run at 2933 MT/s with CL21 latency at 1.20V, giving you the rated DDR4 2933 bandwidth provided your motherboard enables that speed for unbuffered UDIMMs.

Is this kit limited by the DDR4 UDIMM interface or the 288-pin connector in practice?

The 288-pin DDR4 UDIMM interface caps transfer rate at the module's 2933 MT/s specification; the unbuffered design means no register delay, so the practical limit is the rated speed and CL21 timing.
