Exact-match DDR4-3200 kit for Supermicro X12SPA-TF

This 64 GB kit contains four 16 GB DDR4-3200 ECC RDIMMs built to the Supermicro X12SPA-TF memory specification. The modules are 1Rx8 registered DIMMs that the board recognises at full capacity and rated speed.

DDR4-3200 registered ECC limits

The DDR4-3200 interface tops out at PC4-25600 bandwidth and requires registered DIMMs; unbuffered UDIMMs or SODIMMs will not work. Population rules in the motherboard manual dictate slot order and maximum supported capacity per channel.

64 GB headroom for virtualised workloads

Four ranks of 16 GB each fill four slots and give ample room for multiple virtual machines or large databases. Workloads that exceed 64 GB or need higher memory frequency will require a platform that supports larger or faster modules.

Questions about this item

Should I choose the 64GB kit or a smaller capacity for my Supermicro X12SPA-TF?

The 64GB kit provides four 16GB modules, filling four slots for full capacity. Check your motherboard manual for supported configurations and maximum memory per slot.

What does the DDR4 3200MHz rating mean for real-world server performance?

The modules run at 3200 MT/s with CL22 latency at 1.2V. Registered ECC design lets the memory controller handle full population stably, reducing errors under heavy workloads.

Will the 288-pin RDIMM interface work at full speed on my motherboard?

Yes, the 288-pin Registered DDR4 RDIMM matches the X12SPA-TF slot and DDR4 3200 PC4-25600 spec. The board's memory controller determines the final operating speed.
