NEMIX RAM

NEMIX RAM 64GB 4x16GB DDR4 2933MHz CL21 1Rx8 UDIMM memory upgrade

SKU CH-B5ZY-P4EP5

A 64 GB DDR4 kit of four 16 GB UDIMMs running at 2933 MHz CL21, verified for Supermicro X12SCQ and X12SCZ-QF motherboards

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeUnbuffered

Size 64GB 4X16GB

  • Exact 64 GB (4 × 16 GB) DDR4-2933 kit matches controller specs for full-speed recognition
  • Verified fit for Supermicro X12SCQ and X12SCZ-QF motherboards with 288-pin UDIMM form factor
  • Built with major OEM chips from Samsung, Micron, Hynix and tested at rated speed, timing and voltage
  • Low 1.2 V operation and CL21 latency reduce power draw while maintaining stable throughput
  • Lifetime replacement coverage with free US-based technical support included

Targeted Upgrade Kit

This 64GB kit contains four 16GB DDR4 UDIMM modules rated at 2933MHz with CL21 timings. It is built for owners of Supermicro X12SCQ or X12SCZ-QF motherboards who need the exact rank, voltage and timing the board expects. The non-ECC unbuffered design matches the desktop memory controller on these platforms.

Sustained Operation

Major OEM chips from Samsung, Micron or Hynix are tested at the rated 1.20V and 2933MHz speed for stability during long workloads. The 1Rx8 organisation keeps the electrical load consistent across all four slots. No heat spreader is fitted, so airflow in the chassis handles thermal management directly.

Deciding Specification

The motherboard requires 288-pin DDR4 UDIMM modules at PC4-23400 with 1Rx8 ranking and 1.2V operation. If your board calls for ECC, registered DIMMs, a different voltage or a different rank structure, this kit will not be recognised at full capacity or speed.

Questions about this item

How much power does the 1.2 V DDR4 kit draw when the system runs all day?

Each module operates at 1.2 V, the standard DDR4 voltage, so total power draw stays within the motherboard's normal DIMM slot budget during continuous use.

What motherboard slot and population rules must my Supermicro board already support for this 4 × 16 GB kit?

The kit needs four free 288-pin UDIMM slots and follows the X12SCQ/X12SCZ-QF population order; consult the board manual for the exact sequence before installing.

Will the CL21 2933 MHz modules run correctly alongside any existing DDR4 sticks I keep in the same board?

Mixed speeds or timings force all modules to the slowest common settings; for guaranteed rated performance use this matched 64 GB kit alone.
