Exact-match DDR4-3200 upgrade

This 64 GB DDR4-3200 (PC4-25600) module is built for the Supermicro X12SPA-TF motherboard. It delivers registered ECC memory that meets the board's rank, voltage, and timing requirements so the controller recognises full capacity at rated speed.

Install and population rules

The 288-pin RDIMM form factor fits only registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Follow the motherboard manual for supported capacities, approved population order, and installation steps before adding modules.

Capacity and headroom

A single 64 GB 2Rx4 registered ECC DIMM runs at 3200 MT/s with CL22 latency and 1.2 V power. Total system capacity depends on the number of slots populated and the board's maximum supported memory per channel.

Questions about this item

How do I confirm the 64GB DDR4 3200 module is running at its rated speed after installation?

Enter the BIOS or UEFI and verify the memory frequency shows 3200 MHz and the CAS latency reads CL22. The registered ECC design lets the board train at full speed when populated per the manual.

What does the package contain and what extra items are needed?

The box includes one 64GB 288-pin DDR4 RDIMM rated at 1.2 V. No cables, brackets or additional parts are required; the motherboard slot provides power and signalling.

Which capacity or rank should I choose for the Supermicro X12SPA-TF?

This 64GB 2Rx4 registered ECC DIMM matches the board's validated population rules. Check the motherboard manual for supported capacities per slot and the correct installation order before buying.
