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

SKU CH-BH61-B60BV

8GB DDR4 2933MHz ECC UDIMM adds error-correcting memory to Supermicro X12SAE and X12SCA-F motherboards

  • Total capacity8 GB
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeUnbuffered

Size 8GB

  • ECC protects data integrity by correcting single-bit errors on the fly
  • 8 GB DDR4-2933 PC4-23400 matches Supermicro X12SAE and X12SCA-F spec exactly
  • 1Rx8 unbuffered UDIMM installs directly without registered or SODIMM mismatch
  • CL21 timing at 1.2 V runs at rated speed without manual tuning
  • Major OEM Samsung Micron Hynix chips deliver consistent reliability

8GB DDR4 ECC UDIMM for Supermicro Boards

This 8GB DDR4 2933MHz ECC unbuffered UDIMM is built for Supermicro X12SAE and X12SCA-F motherboards. It delivers 8GB of error-correcting memory at 1.2V with CL21 latency. The 288-pin module matches the exact rank and timing the platform expects for full-speed operation.

Suited for ECC server upgrades.

This module suits administrators upgrading Supermicro X12SAE or X12SCA-F systems that require unbuffered ECC UDIMMs. Builders needing registered DIMMs, SODIMM form factors, or non-ECC memory for consumer platforms should look elsewhere. Systems not validated for 1Rx8 DDR4-2933 ECC UDIMMs will not support this part.

288-pin DDR4 ECC UDIMM form factor

The single decisive specification is the 288-pin DDR4 ECC UDIMM form factor. Only motherboards wired for unbuffered ECC UDIMMs at DDR4-2933 will recognise this module at its rated 2933MHz speed and 8GB capacity. Any other slot type — RDIMM, SODIMM or non-ECC — will reject it physically or electrically.

Questions about this item

Does my Supermicro X12SAE motherboard need a free 288-pin DDR4 UDIMM slot for this 8GB ECC module?

Yes. The module is a 288-pin DDR4 ECC UDIMM that fits the standard unbuffered DIMM slots on the X12SAE or X12SCA-F.

Can I mix this 1Rx8 CL21 stick with existing 2Rx8 DDR4-2933 ECC UDIMMs on the same board?

The X12SAE and X12SCA-F support mixed-rank populations; install modules in the order the manual specifies and the system will run at the lowest common speed and latency.

How can I confirm the module is running at DDR4-2933 with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode; it should report 2933 MT/s, CL21, 1.20 V and ECC enabled for the new DIMM.
