Exact-match DDR4-2933 upgrade for Supermicro

This 8 GB NEMIX RAM module is a 288-pin UDIMM rated at 2933 MHz (PC4-23400) with CL21 latency and 1.20 V operation. It uses a 1Rx8 non-ECC unbuffered layout built from major OEM Samsung, Micron or Hynix chips. The spec matches the memory controller expectations of the listed Supermicro motherboards so the full capacity is recognised at rated speed.

Check motherboard manual for DIMM population rules

Desktop and motherboard memory support varies by model so consult the system or board manual for supported capacities and approved DIMM population order before purchase. Verify that the board accepts non-ECC unbuffered UDIMMs and that an 8 GB 1Rx8 module fits the intended slot configuration. No heat spreader is fitted so ensure case airflow is adequate for the memory area.

Suits owners of X12SAE

Builders who need ECC registered modules or SODIMM form factor should look elsewhere. Buyers wanting higher capacity per slot or lower latency timings than CL21 will need different modules. Systems requiring a different DDR generation or voltage are not compatible with this kit.

Questions about this item

Does the box contain just the 8GB DDR4 2933MHz UDIMM or are cables and tools included?

The package contains only the single 8GB DDR4 2933MHz PC4-23400 1Rx8 1.2V CL21 288-pin Non-ECC Unbuffered UDIMM module. No cables, screws or installation tools are supplied.

Should I choose the 1Rx8 CL21 version or look for a dual-rank or lower-latency alternative for the Supermicro X12SAE?

The X12SAE and X12SCA-F memory controller expects exactly this 1Rx8 Non-ECC Unbuffered UDIMM at 1.2V CL21. A dual-rank or different CAS latency module may not be recognised or may run at reduced speed.

Will the rated 2933MHz speed actually be reached once the module is installed in the X12SAE motherboard?

Yes. The module is spec-matched to the Supermicro X12SAE and X12SCA-F population rules, so the board will detect it at full 8GB capacity and operate it at the rated DDR4 2933MHz PC4-23400 speed with CL21 timing.
