128 GB DDR4 ECC RDIMM for Supermicro X12SPT-G

This registered ECC module delivers 128 GB of DDR4 3200 memory for compatible Supermicro X12SPT-G and X12SPT-GC motherboards. The 2Rx4 organisation and CL22 timing match the platform's memory controller requirements for full-capacity recognition.

Who should buy this and who should not

Server administrators upgrading Supermicro X12SPT-G or X12SPT-GC systems with validated DDR4 RDIMM memory should buy this. Builders needing unbuffered UDIMM, SODIMM form factors, non-ECC memory, or capacities beyond 128 GB per module should look elsewhere.

2Rx4 registered architecture decides fit

The 2Rx4 registered design offloads the memory controller so every slot runs fully populated at rated speed. ECC corrects single-bit errors on the fly. Confirm your motherboard manual supports this rank, voltage, and population order before purchase.

Questions about this item

Will DDR4 3200 PC4-25600 run at 3200MHz on my Supermicro X12SPT-G?

Yes, the PC4-25600 rating means the module is rated for 3200MHz and the Supermicro X12SPT-G supports that speed when populated per the board's rules.

Does this 288-pin RDIMM fit the DIMM slots on a Supermicro X12SPT-GC?

The X12SPT-GC uses 288-pin DDR4 RDIMM slots; this module matches that form factor and the 2Rx4 registered layout the board expects.

What population order should I follow when installing this 128GB kit?

Install DIMMs in the sequence shown in the Supermicro X12SPT-G manual — typically filling the farthest slot from the CPU first on each channel — to ensure the 2Rx4 registered modules train at 3200MHz.
