Exact-match server memory kit

This 64 GB kit contains two 32 GB DDR4 Registered ECC RDIMMs rated at 3200 MT/s with CL22 timing and 1.2 V operation. It is built for Supermicro X12SPT-G and X12SPT-GC motherboards that require 288-pin Registered modules. The 2Rx8 organization matches the board's memory-controller expectations for full-capacity recognition.

Verify board population rules

Check your motherboard manual for the approved DIMM population order and maximum supported capacity per channel before ordering. Registered ECC RDIMMs are not interchangeable with unbuffered UDIMMs or SODIMMs, so the slot type must match exactly. Confirm that your system BIOS is current enough to initialise the modules at their rated speed.

Enterprise-grade registered design

The registered architecture buffers address and control signals, reducing electrical load on the memory controller when all slots are populated. On-die ECC corrects single-bit errors in real time, preventing silent data corruption in production workloads. Modules ship without heat spreaders, relying on standard server airflow for thermal management.

Questions about this item

What does the kit include and do I need any extra parts?

The kit contains two 32 GB DDR4 3200 CL22 2Rx8 ECC Registered RDIMM modules (64 GB total). No additional components are required for installation.

Which version of this memory should I pick for a Supermicro X12SPT-G or X12SPT-GC board?

Choose the 64 GB (2 × 32 GB) DDR4 3200 PC4-25600 2Rx8 1.2 V CL22 288-pin ECC RDIMM kit — it matches the board’s registered DIMM slot, rank, voltage and timing requirements exactly.

What does the 3200 MT/s rating mean once the modules are installed in the server?

The memory controller will recognise the JEDEC DDR4-3200 profile and run each module at 3200 MT/s with CL22 latency at 1.2 V, delivering the rated PC4-25600 bandwidth when populated per the motherboard manual.
