Exact-match DDR4 RDIMM kit for Supermicro

This 64 GB kit contains two 32 GB DDR4 3200 MHz modules built to the PC4-25600 standard. Registered ECC RDIMM architecture with 2Rx8 organisation and CL22 latency at 1.2 V matches the memory controller requirements of the Supermicro X12DPFR-AN6 motherboard. The kit is intended for servers that require registered error-correcting memory in a 288-pin form factor. It is not for systems that accept only unbuffered UDIMMs or SODIMMs.

DDR4 3200 registered ECC limits and population rules

DDR4 3200 sets the maximum data rate at 3200 MT/s with a PC4-25600 bandwidth ceiling. Registered buffering allows full-slot populations without overloading the memory controller, but the motherboard dictates the exact population order and maximum capacity per channel. ECC corrects single-bit errors on the fly yet cannot recover from multi-bit failures. Mixing ranks, voltages or speeds voids the rated timing and may prevent the system from posting at the advertised 3200 MHz speed.

Straightforward 288-pin RDIMM installation

Align the module notch with the 288-pin slot key and press firmly until both retention clips engage. The Registered RDIMM form factor fits only motherboards designed for registered memory; UDIMM-only boards will not accept it. Common issues include ignoring the motherboard manual's slot-population sequence, mixing this kit with existing modules of different rank or voltage, and failing to update the BIOS to a version that supports the full 64 GB capacity.

Questions about this item

Should I pick this 64 GB kit or a smaller capacity for my Supermicro X12DPFR-AN6?

Choose the 64 GB (2 x 32 GB) kit when your workload needs maximum registered ECC capacity and the motherboard manual confirms both slots can be populated with 2Rx8 modules at DDR4-3200.

What does the 3200 MHz rating actually deliver once installed?

The modules run at DDR4-3200 (PC4-25600) with CL22 latency at 1.20 V, giving the full rated throughput the X12DPFR-AN6 memory controller expects when both DIMM slots are filled.

How does the 288-pin RDIMM interface limit speed or capacity on this board?

The 288-pin registered ECC form factor is exactly what the X12DPFR-AN6 requires; it enables full-speed DDR4-3200 operation across both slots while the registered buffer lets the memory controller drive the 2Rx8 density at 1.20 V without signal degradation.
