  • 256 GB total capacity from four 64 GB modules
  • DDR4 3200 speed rated at PC4-25600 bandwidth
  • CL22 latency with 1.20 V registered operation
  • ECC and 2Rx4 rank for error correction and full-slot stability
  • 288-pin RDIMM form factor validated for Supermicro X12SPT-G/GC

Targeted Server Upgrade

This 256GB kit contains four 64GB DDR4 RDIMMs built for the Supermicro X12SPT-G and X12SPT-GC motherboards. It delivers the exact registered ECC modules those boards require for full-capacity operation.

Registered ECC Architecture

The 2Rx4 registered design with ECC offloads the memory controller and corrects single-bit errors automatically. This combination is the single specification that lets the motherboard recognise every slot at the rated 3200MHz speed.

Capacity and Limits

Four modules populate the board to 256GB total, providing headroom for virtualisation and large databases. Workloads that exceed this capacity or need unbuffered UDIMMs cannot use this kit.

Questions about this item

What does the 3200MHz speed mean for actual performance in a Supermicro X12SPT-G?

DDR4-3200 runs at its rated frequency when the memory controller and BIOS support it; the registered buffer and ECC operate without reducing the clock speed.

How does the PC4-25600 rating relate to the DDR4-3200 interface in this kit?

PC4-25600 is the JEDEC designation for DDR4-3200 bandwidth; the kit is built to that standard and will negotiate that rate on a compatible board.

What physical slot and clearance does this 288-pin RDIMM kit require?

It needs a standard 288-pin DDR4 RDIMM slot on the X12SPT-G or X12SPT-GC; no heat spreader means low-profile clearance is sufficient.
