NEMIX RAM

NEMIX RAM DDR4 3200 ECC UDIMM 64GB (2x32GB) CL22 1.2V 2Rx8 288-pin memory upgrade

SKU CH-RD44-H4RE1

64 GB DDR4 ECC UDIMM kit running at 3200 MHz CL22 1.2 V for Supermicro X12STE-F and X12STD-F boards

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Rated voltage1.2 V

Size 64GB 2X32GB

  • 64 GB kit (2 × 32 GB) doubles system capacity for heavy workloads
  • DDR4-3200 (PC4-25600) speed matches the controller spec so modules run at rated frequency
  • ECC UDIMM detects and corrects single-bit errors on the fly preventing silent data corruption
  • 20 V CL22 2Rx8 timing is the exact rank, voltage and latency the board expects for full recognition
  • Validated for Supermicro X12STE-F and X12STD-F motherboards ensuring correct 288-pin unbuffered fit

Exact-Match DDR4 ECC Kit

This NEMIX RAM kit delivers 64 GB of DDR4-3200 ECC UDIMM memory in a matched pair of 32 GB modules. It is built for workstations and servers that require error-correcting code to protect data integrity during continuous operation. The unbuffered design suits motherboards that do not accept registered DIMMs.

Verify Board Population Rules

Before ordering, consult the Supermicro X12STE-F or X12STD-F manual for supported capacities, approved DIMM population order, and voltage requirements. The kit uses 2Rx8 organization at 1.20 V and 288-pin UDIMM form factor, which must match the board's memory-controller expectations. Installing modules in the wrong slots or exceeding the validated capacity can prevent boot or limit speed.

Sustained Load Stability

Under sustained load, ECC circuitry continuously detects and corrects single-bit errors to prevent silent data corruption and unplanned reboots. The CL22 timing and standard 1.20 V operation keep power draw predictable during long compute runs. Without a heat spreader, adequate case airflow is necessary to maintain rated performance over extended periods.

Questions about this item

What comes inside the 64GB kit and do I need anything else to install it?

The kit contains two 32GB DDR4 3200MHz PC4-25600 2Rx8 1.2V CL22 288-pin ECC UDIMM modules. No extra parts are required for installation into a compatible Supermicro motherboard.

Should I choose this 64GB (2x32GB) kit or a different capacity for my Supermicro X12STE-F or X12STD-F?

This 64GB kit uses two 32GB 2Rx8 ECC UDIMMs that match the board's DDR4 3200 PC4-25600 specification. Select it when your workload needs 64GB total and your motherboard manual confirms two-DIMM population at that capacity.

What does the CL22 rating mean when the memory is running in my Supermicro system?

CL22 is the CAS latency at DDR4 3200 (PC4-25600). The memory controller will operate the kit at 1.2V with 22 clock cycles of column access delay, delivering the rated ECC error-correction and throughput for the X12STE-F or X12STD-F platform.
