Four green DDR4 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 128GB 4x32GB DDR4 3200 CL22 ECC RDIMM Supermicro X12DPFR-AN6

SKU CH-GQF1-E1X4Y

128 GB DDR4 3200 ECC registered RDIMM kit of four 32 GB modules at CL22 and 1.2 V, validated for the Supermicro X12DPFR-AN6 motherboard

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22

Size 128GB 4X32GB

  • 128 GB capacity across four 32 GB modules for maximum server density
  • DDR4 3200 speed with CL22 latency matches the motherboard's rated specification
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 20 V operation at 2Rx8 rank aligns with the platform's memory controller requirements
  • 288-pin RDIMM form factor ensures exact fitment in Supermicro X12DPFR-AN6 DIMM slots

Exact-Match Kit for Supermicro X12DPFR-AN6

This 128 GB kit contains four 32 GB DDR4-3200 Registered ECC RDIMMs built to the precise rank, voltage, and timing the Supermicro X12DPFR-AN6 memory controller expects. The 2Rx8 organisation and CL22 latency at 1.2 V let the board recognise full capacity and run at rated speed without manual tuning.

Sustained Enterprise Stability

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity during continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots before they reach production systems.

Installation Notes and Common Issues

Modules are keyed 288-pin RDIMMs; they only fit the correct server DIMM slots and cannot be inserted into UDIMM or SODIMM sockets. Population order matters — consult the motherboard manual for the approved sequence, otherwise the system may not boot or may report reduced capacity.

Questions about this item

How much power does the 1.20 V DDR4 3200 kit draw when the server runs all day?

The kit operates at 1.20 V; actual power draw depends on the motherboard's memory controller and population rules, so consult the Supermicro X12DPFR-AN6 manual for system-level figures.

What motherboard feature must I already have for this 288-pin RDIMM kit to work?

The Supermicro X12DPFR-AN6 must provide DDR4 RDIMM slots that support Registered ECC memory and the correct population order for four 2Rx8 modules.

Will these 3200 CL22 modules run at rated speed alongside older DDR4 DIMMs I keep in the same server?

Mixing different speeds, latencies or ranks can force all channels to the slowest common settings; the board manual specifies approved population rules for full-speed operation.
