Exact-match server upgrade

This 128GB kit contains eight 16GB DDR4-3200 RDIMMs built to the PC4-25600 standard. Registered ECC modules with 1Rx8 organisation and CL22 timing at 1.2V are specified for Supermicro X12SPT-G and X12SPT-GC motherboards. The kit delivers the precise rank, voltage and latency the platform expects.

Registered ECC limits

Registered architecture buffers address and command signals so the memory controller can drive every slot at full speed when all eight sockets are populated. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. DDR4-3200 is the maximum rated frequency; the board will not run these modules faster.

No spreader, standard mounting

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense server configurations. The 288-pin RDIMM form factor fits only DDR4 registered DIMM slots; it is not compatible with UDIMM or SODIMM sockets. Verify the motherboard manual for approved population order before installation.

Questions about this item

Should I choose the 8x16GB kit or a different capacity for my Supermicro X12SPT-G motherboard?

The 8x16GB kit provides 128GB total capacity across all eight DIMM slots, matching the board's maximum supported population for full-speed operation.

What does the DDR4-3200 rating mean for actual throughput in my server?

DDR4-3200 (PC4-25600) delivers up to 25,600 MB/s per module, so eight modules running together give the memory controller its full rated bandwidth.

How does the registered ECC interface affect stability and slot limits?

Registered (buffered) ECC RDIMMs reduce electrical load on the memory controller, allowing all eight slots to run at 3200 MHz while ECC corrects single-bit errors automatically.
