Exact-match DDR4-3200 ECC RDIMM kit

This 128GB kit contains four 32GB DDR4 3200 (PC4-25600) Registered ECC RDIMMs built to CL22 at 1.20V. The 2Rx8 organisation matches the memory controller expectations of the Supermicro X12QCH+ motherboard so the full capacity is recognised at rated speed. It is intended for administrators upgrading that specific server platform with validated modules.

Straightforward DIMM installation

Installation follows the motherboard manual: power down, open the chassis, align the 288-pin key and press each module until the retention clips lock. Registered architecture offloads the controller so all four slots can be populated without signal degradation. The common error is ignoring the board's population order or mixing ranks, which prevents the system from posting at full capacity.

Verify supported capacity and population rules

Before ordering, consult the Supermicro X12QCH+ manual for the maximum memory per socket, approved DIMM population sequence, and any BIOS revision required for 128GB kits. The board must accept 2Rx8 Registered ECC RDIMMs at DDR4-3200 1.20V. Buyers who need a different rank configuration, UDIMM form factor, or higher frequency than 3200MHz cannot use this kit.

Questions about this item

How do I verify the kit is running at DDR4 3200 CL22 after installation?

Check the BIOS memory information or use a tool like CPU-Z to confirm the speed reads 3200 MT/s and the CAS latency shows 22 with all four 32 GB modules detected.

What comes in the box and what must be purchased separately?

The kit includes four 32 GB DDR4 288-pin ECC Registered RDIMMs for a total of 128 GB; no cables, brackets, or additional components are required.

Which capacity or version of this kit should I choose for my Supermicro X12QCH+?

Select this exact 128 GB (4 x 32 GB) DDR4 3200 CL22 2Rx8 1.2 V RDIMM kit, as it matches the motherboard's validated population rules and voltage.
