SuperMicro DDR4 2933MHz Kit

This 16GB kit contains two 8GB DDR4 UDIMM modules rated at 2933MHz with CL21 latency. It is built for SuperMicro desktop and SuperWorkstation motherboards such as the MBD-C9X299-PGF. The unbuffered, non-ECC design suits standard workstation workloads.

Upgrade from lower capacity or speed

Replacing a smaller DDR4 kit or slower modules adds bandwidth for multi-threaded applications and virtual machines. The jump is worth it when the board supports 2933MHz operation and the workload exceeds the current memory ceiling.

Check motherboard qualification list

Verify that the specific SuperMicro model accepts 1Rx8 288-pin UDIMMs at 1.2V without ECC. Confirm the number of available slots and the maximum supported capacity per slot before ordering.

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit my Supermicro motherboard's memory slots?

Yes, the 288-pin DDR4 UDIMM form factor matches standard desktop and workstation DIMM slots on compatible Supermicro boards.

What is the correct way to seat the two 8GB sticks so the system recognises the full 16GB kit?

Align the notch on each module with the slot key, press straight down until both side clips click, and populate the channels indicated in the motherboard manual.

Do these non-ECC unbuffered modules require any firmware updates or periodic re-seating over time?

No firmware updates are needed for the memory itself, and the gold-edge contacts do not require routine re-seating under normal operation.
