NEMIX RAM
Adds 8 GB of DDR4 3200 ECC registered memory with CL22 latency for Micron-compatible servers
This 8 GB registered DIMM runs at DDR4 3200 with a CAS latency of CL22 and 1.20 V. It is built for Micron server and workstation platforms that require ECC error correction and registered signalling. The single-rank 1Rx8 organisation uses 288-pin DDR4 RDIMM form factor. Buyers who need unbuffered UDIMM modules or non-ECC memory for desktop boards cannot use this product.
Registered ECC memory only functions in motherboards that explicitly support RDIMM and ECC operation; consumer chipsets will not initialise the module. The DDR4 3200 PC4-25600 interface provides the stated bandwidth within the server's qualified memory population rules. Mixing registered and unbuffered DIMMs, or exceeding the platform's rank-per-channel limit, will prevent the system from posting.
The 288-pin RDIMM inserts vertically into the server's DDR4 memory slots; alignment notches prevent incorrect orientation. No heat spreader is fitted, so clearance is minimal inside dense chassis. Always consult the system owner's manual for supported population order and maximum capacity per channel before installing. Incorrect slot order or unsupported rank configuration are the most common reasons the module is not recognised.

This listing is a single 8GB 1Rx8 registered DIMM; add more identical modules to reach the total capacity your server board supports.
The module runs at DDR4-3200 (PC4-25600) with CL22 latency, providing ECC error correction and registered buffering for stable throughput in compatible Micron systems.
The 288-pin DDR4 RDIMM form factor fits only DDR4 registered DIMM slots; it cannot be used in unbuffered UDIMM, SO-DIMM or DDR5 sockets.
