128GB DDR4-3200 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR4-3200 registered ECC modules. It is built for servers and workstations that require registered DIMMs with error correction. The modules run at 1.2V with CL22 latency and a 1Rx8 rank structure.

Suited for Supermicro X12SPA-TF upgrades

This kit matches the Supermicro X12SPA-TF motherboard when that board calls for DDR4-3200 registered ECC RDIMMs in an eight-module population. It is not for systems that only accept unbuffered UDIMMs, SODIMMs, or a different DDR generation.

Registered ECC with 1Rx8 organisation

The registered buffer and ECC function let every slot run fully populated while correcting single-bit errors. The 1Rx8 rank layout is the specific attribute the memory controller checks to recognise the full 128GB at rated speed.

Questions about this item

Should I choose the 8x16GB kit or a different capacity for my Supermicro X12SPA-TF?

This kit provides 128GB total across eight 16GB modules. It matches the board's DDR4 3200MHz PC4-25600 spec and 288-pin RDIMM form factor. Verify your motherboard manual for supported capacities and population rules before ordering.

Will the DDR4 3200MHz PC4-25600 speed run at its rated frequency in my server?

The modules are spec-matched to the Supermicro X12SPA-TF's memory controller with 1Rx8 rank, 1.2V voltage and CL22 latency. When installed per the board's population order, they are recognized at full capacity and operate at the rated 3200MHz speed.

How does the 288-pin RDIMM interface affect maximum capacity and stability?

Registered (buffered) RDIMMs offload the memory controller, allowing all eight slots to run fully populated at 128GB total. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.
