Four green circuit boards with black memory chips, no heat spreaders, 288-pin DDR4 UDIMM form factor

NEMIX RAM

NEMIX RAM DDR4 ECC Unbuffered UDIMM 64GB (4x16GB) 2933MHz CL21 1.2V 288-Pin memory upgrade

SKU CH-47Y8-HMJG1

64 GB kit of four 16 GB DDR4 ECC unbuffered UDIMMs running at 2933 MHz CL21 1.2 V for Supermicro X12SAE and X12SCA-F 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

  • ECC protection stops silent data corruption with single-bit error correction
  • 64 GB total capacity delivered as four 16 GB modules for full population
  • DDR4-2933 CL21 at 1.2 V matches the board's rated speed and timing
  • 288-pin unbuffered UDIMM form factor fits Supermicro X12SAE and X12SCA-F slots exactly
  • Major OEM Samsung, Micron or Hynix chips ensure validated component quality

Exact-match 64 GB DDR4 ECC kit

This 64 GB kit contains four 16 GB unbuffered ECC UDIMMs that run at DDR4 2933 with CL21 latency at 1.2 V. It is built for owners of Supermicro X12SAE or X12SCA-F motherboards who need the precise rank, voltage and timing the board expects.

Capacity and headroom for ECC workloads

Four 1Rx8 modules populate the board's four DIMM slots and deliver 64 GB of error-correcting memory for virtualization, ZFS storage or database tasks. Workloads that exceed 64 GB will require a platform that supports larger DIMMs or higher-density kits.

DDR4 2933 unbuffered ECC UDIMM requirement

The motherboard only accepts 288-pin unbuffered ECC UDIMMs at DDR4 2933; registered DIMMs, SODIMMs or non-ECC modules will not work. Verify your board's qualified-vendor list and population rules before ordering.

Questions about this item

Will this DDR4 2933MHz CL21 1Rx8 kit run alongside existing DDR4 modules in a Supermicro X12SAE?

The kit is specified as an exact-match upgrade for the X12SAE and X12SCA-F at DDR4-2933 PC4-23400. Mixing modules with different speeds, ranks, or latencies can prevent the board from running at the rated speed or cause instability. For best results, populate all slots with identical 1Rx8 unbuffered ECC UDIMMs at 1.2V CL21.

How can I confirm the 64GB kit is detected at 2933MHz with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 2933MHz (PC4-23400), total capacity shows 64GB, and ECC is reported as enabled. In the operating system, tools such as dmidecode on Linux or CPU-Z on Windows will also display the speed, rank (1Rx8), voltage (1.2V), and ECC status.

Does the box contain only the four 16GB UDIMMs, or are any cables, screws, or tools included?

The package content lists only the 64GB kit of four 16GB DDR4 2933MHz PC4-23400 1Rx8 1.2V CL21 288-pin ECC unbuffered UDIMMs. No cables, brackets, screws, or installation tools are included.
