NEMIX RAM 8GB DDR4 2933MHz PC4-23400 1Rx8 CL21 288-PIN ECC Unbuffered UDIMM memory upgrade

SKU CH-A78F-2DJB5

8GB DDR4-2933 ECC UDIMM with CL21 timing and 1.2V operation for Supermicro X12SCZ motherboards

  • Capacity8GB
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes

Size 8GB

  • ECC corrects single-bit errors on the fly preventing silent data corruption
  • 2933 MHz DDR4 speed with CL21 latency delivers rated performance for Supermicro boards
  • 1Rx8 unbuffered 288-pin UDIMM matches exact motherboard slot and population rules
  • 2 V operation meets JEDEC standard voltage for stable low-power operation
  • Built with major OEM Samsung Micron Hynix chips for consistent quality and reliability

Exact-match 8 GB DDR4 ECC UDIMM

This 8 GB DDR4-2933 module delivers PC4-23400 bandwidth at 1.2 V with CL21 latency. It uses a 1Rx8 unbuffered ECC layout on a 288-pin UDIMM so the memory controller recognises the rated speed and capacity immediately. The stick targets Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards that require this precise rank, voltage and timing combination. Builders needing error-correcting memory for data-integrity workloads will find the spec match they need.

Verify motherboard population rules

Consult the Supermicro manual for supported capacities, approved DIMM population order and installation steps before ordering. The board accepts only 288-pin unbuffered ECC UDIMMs — not RDIMMs or SODIMMs — so confirm your slots follow the vendor-approved sequence. Systems that demand registered or load-reduced modules will not work with this unbuffered design. Buyers who need larger capacities per slot or a registered form factor cannot use this kit.

Thermals noise and power draw

Operating at 1.2 V without a heat spreader, the module runs cool and silent under normal loads. The low-voltage DDR4 design keeps power draw modest while ECC correction runs transparently in the background. No active cooling is required on the DIMM itself. Systems that rely on high-airflow chassis fans will see no additional acoustic contribution from this memory.

Questions about this item

Does the package include only the 8GB DDR4 2933MHz ECC UDIMM module, or are any cables or tools required?

The box contains the single 8GB DDR4 2933MHz PC4-23400 1Rx8 CL21 288-pin ECC Unbuffered UDIMM; no cables, tools or additional hardware are supplied.

Should I choose this 8GB 1Rx8 CL21 kit or a different capacity or rank for my Supermicro X12SCZ-F board?

This exact-match 8GB 1Rx8 CL21 module meets the board's DDR4 2933MHz ECC UDIMM requirement; consult your motherboard manual for approved population order and maximum capacity before selecting a different size or rank.

What does the 2933MHz PC4-23400 rating mean once the module is installed in the Supermicro system?

The memory controller will recognise the JEDEC 2933MHz PC4-23400 speed at 1.20V with CL21 timing, delivering the rated bandwidth and ECC error correction without manual configuration.
