This 128GB memory is 100% compatible with Maxdata Platinum 3200 I M9. The following technical specifications should be considered: RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) RAM memory can be installed in the unit. LRDIMM memories are recommended for achieving large memory capacities. RDIMM and RDIMM 3DS memory modules cannot be mixed with LRDIMM and LRDIMM 3DS RAM. If a memory expansion is to be carried out with the existing RAM, it must be checked which basic memory technology (RDIMM / LRDIMM) is available. If memory modules are offered with higher clock rates than specified by the system, the memory clock is automatically adjusted to the system specifications. Memory for Intel Xeon CPUs includes:

• RDIMM:
• Xeon E5-16xx v3: 8GB, 16GB, 32GB, 64GB, 128GB
• Xeon E5-26xx v3: 8GB, 16GB, 32GB, 64GB, 128GB
• Xeon E5-46xx v3: 8GB, 16GB, 32GB, 64GB, 128GB

• LRDIMM:
• 32GB, 64GB, 128GB, 256GB.
