NEMIX RAM 32GB DDR4 2933 UDIMM

This is a 32GB DDR4 UDIMM module built for SuperMicro workstations and desktop motherboards such as the MBD-C9Z490-PG and MBD-C9Z490-PGW. It runs at 2933 MT/s with a CAS latency of CL21 and operates at 1.2V. The stick uses a 2Rx8 organisation and has no heat spreader.

Who this suits and who should look elsewhere

This module suits administrators upgrading a compatible SuperMicro platform that accepts non-ECC unbuffered DDR4 memory. It is not for systems that require ECC registered DIMMs or that only support lower-density ranks. Buyers needing error correction or higher capacities per slot should look elsewhere.

32GB 2Rx8 DDR4 2933 specification

The single specification that decides fit is the 32GB 2Rx8 DDR4 2933 CL21 1.2V 288-pin UDIMM profile. Your motherboard must support this exact density, rank organisation, speed and voltage without ECC. Verify the qualified vendor list before purchase.

Questions about this item

Will the 288-pin DDR4 UDIMM fit a SuperMicro MBD-C9Z490-PG motherboard?

Yes, the 288-pin DDR4 UDIMM form factor matches the desktop DIMM slots on that SuperMicro board.

Which slot should I use first when installing this single 32GB module?

Install it in the primary slot indicated by your motherboard manual, usually the slot furthest from the CPU socket.

Does this non-ECC unbuffered module require any firmware updates or future replacement?

No firmware updates are needed; the module has no heat spreader and runs at 1.2V, so it is designed for the system's lifetime.
