NEMIX RAM 8GB DDR4 2933MHz CL21 1Rx8 ECC SODIMM memory upgrade

SKU CH-ZJ1G-WCP8Z

8GB DDR4 2933MHz ECC SODIMM with CL21 latency and 1.2V operation for Supermicro X12SCV motherboards

  • Total capacity8 GB
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • ECC corrects single-bit errors on the fly
  • 2933 MHz speed matches system memory controller
  • 20 V low voltage reduces power draw
  • 260-pin SODIMM fits Supermicro X12SCV boards
  • 1Rx8 unbuffered rank enables full capacity recognition

Exact-match DDR4 ECC SODIMM upgrade

This 8GB DDR4 2933MHz CL21 1Rx8 unbuffered ECC SODIMM is built for Supermicro X12SCV-W and X12SCV-LVDS motherboards. It runs at 1.2V with a 260-pin form factor that matches the board's memory controller requirements. The module uses major OEM chips and delivers error-correcting reliability for workstation or server tasks.

Replaces non-ECC or slower DDR4 SODIMMs

If your system currently uses non-ECC memory or lower-speed DDR4 modules, this kit adds single-bit error correction and the exact 2933MHz rating the platform expects. The jump is worth it when data integrity matters for databases, virtualization or long-running compute jobs. It will not fit full-size UDIMM or RDIMM slots.

Check your manual for population rules

Verify the maximum supported capacity per slot and the approved installation order for your specific Supermicro model before ordering. Ensure the board requires unbuffered 260-pin ECC SODIMMs rather than registered or load-reduced variants. Confirm the system accepts 1Rx8 rank configuration at 1.2V.

Questions about this item

Will the 260-pin SODIMM fit my Supermicro X12SCV-W motherboard?

Yes, the 260-pin DDR4 ECC SODIMM form factor matches the slot on the Supermicro X12SCV-W and X12SCV-LVDS boards.

What is the correct slot order when installing this 1Rx8 module?

Install the module in the primary slot first, following the population sequence in your system manual for 1Rx8 unbuffered ECC memory.

Does the ECC function require any future firmware updates or battery replacement?

No, the on-die ECC operates automatically without firmware updates or a backup battery.
