  • 64 GB kit fills every slot for maximum server capacity
  • ECC and registered design corrects single-bit errors and offloads the memory controller
  • 3200 MHz DDR4 speed matches the motherboard's rated frequency for full performance
  • 2 V operation reduces power draw while maintaining stability
  • 288-pin RDIMM form factor fits the Supermicro X12SPA-TF exactly

Exact-fit server memory kit

This NEMIX RAM kit delivers 64 GB of DDR4 3200 registered ECC memory across eight 8 GB modules. It is built to the precise rank, voltage and timing the Supermicro X12SPA-TF memory controller expects for full-speed operation.

Suited for administrators populating every slot

The 1Rx8 registered design keeps the controller stable when all eight DIMM sockets are filled, while on-die ECC corrects single-bit errors before they reach applications. Systems that require unbuffered UDIMMs, SODIMMs or non-ECC modules cannot use this kit.

64 GB headroom for multi-tenant workloads

Eight populated channels provide the bandwidth and capacity needed for virtualisation hosts, database buffers and container clusters. Workloads that exceed 64 GB or demand higher frequencies will require a platform with greater memory support.

Questions about this item

What motherboard must I already have for this 64GB kit of 1Rx8 DDR4 3200 RDIMMs to work?

The kit is verified for the Supermicro X12SPA-TF motherboard; the board must provide 288-pin RDIMM slots that accept registered ECC memory at 1.2V.

Will these eight 8GB DDR4 3200 CL22 modules run at their rated speed when populated in all slots of that board?

Yes, the registered architecture offloads the memory controller so every slot can run fully populated at the rated DDR4 3200 speed with CL22 timings.

How can I confirm the kit is operating at DDR4 3200 with ECC active after installation?

Check the BIOS memory information or the OS hardware report for 3200 MT/s, CL22, 1.2V and ECC enabled across all 64GB.
