Size 256GB 8X32GB

  • 256 GB total capacity from eight 32 GB modules for high-density server workloads
  • DDR4-3200 speed with CL22 latency delivers rated throughput for the Supermicro X12DPFR-AN6
  • Registered ECC RDIMM design offloads the memory controller and corrects single-bit errors automatically
  • 2Rx8 dual-rank organisation enables full-capacity population across all populated slots
  • 2 V operating voltage matches the platform specification for stable operation

Exact-Match Server Kit

This 256GB kit contains eight 32GB DDR4-3200 Registered ECC RDIMMs built to the exact rank, voltage, and timing the Supermicro X12DPFR-AN6 motherboard expects. It is designed for administrators who need full-capacity population across all supported slots without manual tuning.

Registered 288-Pin Form Factor

Each module uses the 288-pin RDIMM form factor required by the target platform; the registered architecture buffers the command bus so every slot remains stable when fully populated. The absence of a heat spreader keeps the profile low for dense server chassis where airflow clearance is tight.

Eight-Module Population Kit

The package delivers eight matched DIMMs in a single kit, eliminating the risk of mixing revision codes or timings across channels. Lifetime replacement coverage and US-based technical support are included for the duration of the deployment.

Questions about this item

What DDR4 speed and PC4 rating does this 256GB kit run at?

The modules operate at DDR4 3200 with a PC4 25600 data rate, matching the Supermicro X12DPFR-AN6 motherboard specification.

Does the 288-pin RDIMM form factor fit the Supermicro X12DPFR-AN6 motherboard slots?

Yes, the 288-pin Registered DIMM form factor is exactly what the board requires; it is not a UDIMM or SODIMM.

What population order should I follow when installing all eight 32GB modules?

Consult the motherboard manual for the approved DIMM population sequence before installing the full 256GB kit.
