Exact-Match Upgrade

This NEMIX RAM module is an 8GB DDR4 3200 registered ECC RDIMM built for Supermicro X12SPT-G and X12SPT-GC motherboards. It delivers the precise 1Rx8 rank, 1.2V voltage and CL22 timing the memory controller expects so the server recognises full capacity at rated speed. The 288-pin registered form factor matches the board's physical and electrical requirements exactly.

Sustained Load Behaviour

Registered architecture buffers the command and address signals to reduce electrical load on the memory controller when every slot is populated. This allows the system to maintain stable operation at full capacity during extended workloads without the signal degradation that can occur with unbuffered modules. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots before they reach production.

Build Quality and Connectors

The module uses major OEM chips from Samsung, Micron or Hynix and carries no heat spreader, keeping the profile low for dense server chassis. A 288-pin gold-edge connector seats firmly in the board's RDIMM slots, and the registered design ensures reliable contact even in fully populated configurations. Buyers needing higher densities or different form factors such as UDIMM or SODIMM will find this module incompatible.

Questions about this item

How much power does the 1.2 V DDR4 3200 RDIMM draw when the server runs continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, so power draw stays low even with all slots populated around the clock.

Does my Supermicro X12SPT-G board need a specific BIOS version or CPU to recognise this 1Rx8 registered ECC DIMM?

The DIMM is validated for the X12SPT-G and X12SPT-GC motherboards; consult the board manual for any BIOS or CPU requirements before installing.

Can I mix this CL22 registered ECC stick with older unbuffered non-ECC DDR4 modules I already own?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the memory controller requires identical registered ECC modules in every populated slot.
