Exact-match server kit

This 512GB kit contains eight 64GB DDR4 registered ECC RDIMMs built for the Supermicro X12DPFR-AN6 motherboard. Each module runs at 3200MHz with CL22 latency at 1.20V. The 2Rx4 dual-rank layout matches the board's memory controller expectations so the full capacity is recognised and operates at rated speed.

DDR4 RDIMM population limits

Registered DIMMs allow every slot to be filled without overloading the memory controller, yet the motherboard still defines the maximum supported capacity per socket and the required population order. Installing modules outside that sequence or exceeding the per-channel rank limit will prevent the system from booting or force reduced speeds.

Guided installation steps

Align the 288-pin key notch with the slot, press straight down until the retention clips click, and follow the manual's exact slot sequence for eight modules. Common issues are mixing RDIMMs with unbuffered UDIMMs, skipping a required slot, or using a BIOS version that does not yet support the full 512GB configuration.

Questions about this item

Should I choose the 8×64 GB kit or a different capacity for my Supermicro X12DPFR-AN6?

The kit provides 512 GB total across eight 64 GB modules, matching the board's DDR4-3200 Registered ECC requirement and 288-pin RDIMM form factor.

What does the DDR4-3200 (PC4-25600) rating mean once installed in the server?

The modules run at 3200 MT/s with CL22 latency at 1.2 V, delivering the full rated bandwidth the memory controller expects when all slots are populated.

How does the Registered ECC 2Rx4 design affect stability and slot population?

Registered buffering offloads the memory controller so every slot runs fully populated at full capacity, while ECC corrects single-bit errors on the fly.
