  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22

  • Buffer typeRegistered
  • 128 GB capacity across four 32 GB modules for dense server workloads
  • DDR4-3200 speed with CL22 latency matches board-rated performance
  • ECC and registered design corrects errors and offloads the memory controller
  • 2 V operation at 2Rx8 rank aligns with Supermicro X12SPT-G specifications
  • 288-pin RDIMM form factor ensures exact fit in validated motherboard slots

Exact-match DDR4 kit

This 128GB kit contains four 32GB DDR4 RDIMM modules rated at 3200MHz with CL22 latency. It is built for the Supermicro X12SPT-G and X12SPT-GC motherboards where registered ECC memory is required.

Capacity and headroom

The 2Rx8 organization and 1.2V operation allow all four slots to run fully populated at the rated PC4-25600 speed. Registered buffering offloads the memory controller so the full 128GB is recognized without down-clocking.

Build and daily use

Modules use major OEM chips from Samsung, Micron, or Hynix and ship without heat spreaders for standard server airflow. The 288-pin RDIMM form factor fits only registered DIMM slots, not UDIMM or SODIMM sockets.

Questions about this item

Will the 3200 MHz DDR4 RDIMMs run at their rated speed alongside the existing memory I keep in the Supermicro X12SPT-G?

The kit is spec-matched to the Supermicro X12SPT-G and X12SPT-GC motherboards at DDR4 3200 PC4-25600, so the memory controller expects these exact timings, voltage and registered ECC behaviour.

How can I confirm the 128 GB ECC RDIMM kit is operating correctly after installation?

The system BIOS will show 128 GB recognised at DDR4 3200 with CL22 and 1.20 V, and the registered ECC function will report corrected single-bit errors in the OS logs if they occur.

What exactly ships in the box and is anything else required to populate the four slots?

The package contains the 128 GB kit as four 32 GB 2Rx8 288-pin DDR4 RDIMMs; no extra cables, brackets or cooling are needed to fill the four slots.
