Supermicro X12DPFR-AN6 Memory Kit

This 512GB kit contains four 128GB DDR4 Registered ECC RDIMMs built for the Supermicro X12DPFR-AN6 motherboard. The modules run at 3200MHz with CL22 latency and 1.2V operation to match the board's memory controller exactly. Enterprise workloads that require full capacity and error correction will benefit from the 2Rx4 registered design.

Verify Motherboard Population Rules

Check your system manual for approved DIMM population order and maximum supported capacity before ordering. The motherboard requires 288-pin Registered RDIMMs and will not accept UDIMM or SODIMM modules. Confirm that your BIOS revision supports the full 512GB configuration across all four slots.

Registered ECC Architecture Changes Reliability

Registered buffering reduces electrical load on the memory controller so every slot operates at full speed when fully populated. ECC corrects single-bit errors automatically to prevent silent data corruption and unexpected reboots. The kit includes only the four memory modules with no additional cables or software utilities.

Questions about this item

Does the 512GB kit ship as four 128GB modules or do I need to buy additional DIMMs?

The kit contains four 128GB DDR4 RDIMMs for a total of 512GB; no extra modules are required to reach that capacity.

Why choose the CL22 2Rx4 registered ECC version over other DDR4 speeds or ranks?

This exact CL22 2Rx4 1.2V registered ECC specification matches the Supermicro X12DPFR-AN6 motherboard's memory controller requirements, ensuring full-speed operation at 3200MHz when all slots are populated.

Will the 3200MHz rating actually run at 3200MHz in a fully loaded Supermicro X12DPFR-AN6?

Yes, because the modules are spec-matched to the board's population rules — 2Rx4 registered ECC at 1.2V and CL22 — the memory controller recognises all 512GB and maintains the rated 3200MHz speed.
