256GB DDR4 ECC RDIMM kit for Supermicro servers

This 256GB kit contains four 64GB DDR4 3200 registered ECC modules built to the exact rank, voltage and timing the Supermicro X12DPFR-AN6 motherboard expects. It targets administrators who need maximum capacity in every slot without manual tuning.

Registered buffering keeps every slot stable

The 2Rx4 registered architecture offloads the memory controller so all four DIMMs run at the rated 3200 speed continuously. ECC corrects single-bit errors on the fly, preventing silent data corruption during sustained workloads.

288-pin RDIMMs install like standard server memory

Align the keyed notch with the slot and press until the latches click; no heat spreaders mean clearance is rarely an issue. The most common error is ignoring the motherboard's prescribed population order, which can leave capacity unrecognised.

Questions about this item

Does the 1.2 V RDIMM kit run hot or draw extra power when the server runs 24/7?

Registered ECC modules operate at the standard 1.2 V DDR4 voltage and have no heat spreader, so thermal output stays within normal server DIMM limits for continuous operation.

My Supermicro X12DPFR-AN6 board has eight DDR4 slots — must I fill all four channels with this 4 x 64 GB kit for it to post?

The kit provides four 288-pin RDIMMs; the motherboard manual defines the required population order, but the modules themselves work in any validated slot configuration the board supports.

Can I keep my existing 32 GB DDR4 RDIMMs and add this 256 GB kit to reach a larger total?

Mixing different capacities or ranks is not recommended; the board's memory controller expects matched 2Rx4 modules at CL22 3200 MT/s for stable full-speed operation.
