Exact-match server kit

This 1 TB kit contains four 256 GB DDR4-3200 Registered ECC RDIMMs built for the Supermicro X12QCH+ motherboard. It targets administrators who need to fill every slot with the precise rank, voltage and timing the platform expects.

8Rx4 registered architecture

The modules run at 1.2 V with CL22 latency and an 8Rx4 organisation that lets the memory controller address the full 1 TB capacity across all four 288-pin slots. Buyers who need unbuffered UDIMMs or a different rank structure cannot use this kit.

Slot-order installation

Populating all four channels requires following the motherboard manual's exact DIMM sequence; skipping the specified order is the most common reason the system fails to recognise the full capacity. No heat spreaders are fitted, so airflow clearance follows the chassis design.

Questions about this item

Will the 3200MHz speed run at full rate on a Supermicro X12QCH+ motherboard?

Yes, the kit is spec-matched to the X12QCH+ memory controller so all four 256GB modules operate at DDR4 3200 (PC4 25600) without down-clocking.

Does the registered DDR4 288-pin interface limit how many modules I can populate?

The registered architecture offloads the memory controller, allowing every slot to run fully populated at full capacity on this motherboard.

What physical clearance does the 8Rx4 RDIMM need inside the server chassis?

Each module is a standard 288-pin DDR4 RDIMM without a heat spreader, so it fits the regular DIMM slots on the Supermicro X12QCH+ board.
