NEMIX RAM
A single 32 GB DDR4 3200 ECC UDIMM module rated CL22 at 1.2 V for Supermicro systems
This 32GB unbuffered DDR4 module adds ECC-protected memory to compatible Supermicro workstations and servers. It operates at 3200MHz with a CAS latency of CL22 and runs at the standard 1.2V. The single 288-pin DIMM uses a 2Rx8 organisation built from major OEM chips.
A single 32GB stick provides substantial capacity for virtualisation, large datasets or memory-intensive applications. The dual-rank 2Rx8 layout helps keep the memory controller busy, though total system capacity will still be limited by the number of available UDIMM slots on the motherboard.
The PC4-25600 interface tops out at 3200MT/s, so bandwidth is capped by the DDR4 standard rather than the module itself. ECC function requires a platform that supports unbuffered ECC UDIMMs; systems without that support will not benefit from error correction.

It uses the same 2Rx8 organisation, 1.2 V voltage and 288-pin DDR4 interface, so it will operate alongside identical-spec DDR4 ECC UDIMMs if your motherboard supports mixed capacities.
Check the BIOS memory information or use a tool such as CPU-Z / dmidecode; both should report 3200 MT/s, CL22 timings and ECC enabled for the new DIMM.
The box contains one 32GB DDR4 3200 2Rx8 CL22 ECC UDIMM; no heat spreader, cables or additional hardware are supplied.
