Exact-match 256 GB DDR4 kit for Supermicro X12SPT-G

This NEMIX RAM kit delivers 256 GB as eight 32 GB DDR4-3200 RDIMMs running at 1.20 V with CL22 latency. Registered ECC modules are purpose-built for the Supermicro X12SPT-G and X12SPT-GC motherboards, matching the required 288-pin RDIMM form factor and 2Rx8 rank structure so the memory controller recognises full capacity at rated speed.

Sustained-load stability

Registered buffering offloads the memory controller, allowing all eight slots to remain fully populated at 3200 MT/s without signal degradation during continuous operation. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots that would otherwise interrupt production workloads.

No heat spreaders and strict population rules

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense server configurations. The 288-pin RDIMM keying prevents accidental installation in UDIMM or SODIMM slots, and the kit must be installed following the motherboard manual's approved population order to ensure compatibility.

Questions about this item

How much heat and power will the 1.2V 2Rx8 registered DIMMs add when the server runs continuously?

Each module operates at 1.2V with standard DDR4 power draw; the registered design reduces electrical load on the memory controller so all eight slots can stay populated without extra voltage or active cooling.

What must the motherboard provide for this 288-pin RDIMM kit to function?

The board needs DDR4 RDIMM slots that support registered ECC memory, a 2Rx8 rank structure and the PC4-25600 speed grade; the Supermicro X12SPT-G and X12SPT-GC are validated platforms.

Will the CL22 timing cause issues if I mix these modules with existing DDR4 RDIMMs in the same system?

The memory controller will negotiate a common speed and latency; all populated channels run at the slowest module's rated timing, so existing RDIMMs stay compatible at the lowered setting.
