NEMIX RAM 512GB DDR4 ECC RDIMM Kit

This 512GB kit contains two 256GB DDR4-3200 Registered ECC modules built for the Supermicro X12QCH+ motherboard. The 8Rx4 organisation, CL22 timing and 1.20V operation match the board's memory controller requirements exactly. It is designed for servers that need maximum capacity per slot in a registered DIMM form factor.

Sustained Load Stability

Registered buffering reduces electrical load on the memory controller so all slots can run fully populated at the rated 3200 MT/s without throttling. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualisation workloads. The modules operate at standard 1.20V DDR4 voltage for consistent thermal behaviour under continuous duty.

Upgrade From Lower-Capacity RDIMMs

This kit replaces smaller Registered ECC DIMMs when the application demands more memory per channel than the previous configuration provides. The jump is worthwhile when the workload exceeds the capacity of the existing modules and the motherboard population rules allow two 256GB 8Rx4 DIMMs. It is not for systems that require unbuffered UDIMMs, SODIMM form factors or speeds other than DDR4-3200.

Questions about this item

How much power does the 512GB DDR4-3200 kit draw at its rated 1.20V?

Each 256GB RDIMM operates at 1.20V; total power depends on the Supermicro X12QCH+ memory controller and population rules, so consult the board manual for exact draw under full load.

What motherboard slot and population rules are required for this 2x256GB RDIMM kit?

The kit uses 288-pin DDR4 RDIMM slots on the Supermicro X12QCH+; follow the board manual for approved DIMM order and maximum capacity per channel.

Will the 8Rx4 registered ECC modules work alongside existing DDR4 RDIMMs in the same server?

Mixing ranks or capacities can prevent full-speed operation; the board manual specifies which slot combinations are supported for 8Rx4 registered ECC DIMMs.
