PHS-memory 32GB RAM memory for Lenovo System x3650 M4 (7915) DDR3 LRDIMM 1333MHz

This 32GB RAM is 100% compatible with the Lenovo System x3650 M4 (7915). What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Technology:
1 CPU: 12 slots
2 CPUs: 24 slots

Maximum RAM expansion based on the number of CPUs and memory slots:

• UDIMM ECC: 64GB RAM (8 x 8GB), 128GB RAM (16 x 8GB)
• RDIMM: 192GB RAM (12 x 16GB), 384GB RAM (24 x 16GB)
• LRDIMM: 384GB RAM (12 x 32GB), 768GB RAM (24 x 32GB)

Principles of memory configuration:
Each CPU has 4 memory channels with 3 memory slots each. ECC DIMM, Registered DIMM, and Load Reduced LRDIMM memory modules must not be mixed. Therefore, when upgrading, you should know which memory is already present or upgrade completely to RDIMM or LRDIMM memory. When using ECC UDIMM memory, only 2 of the 3 memory slots per memory channel can be populated. Memory slots without a processor present must not be populated. Higher memory frequencies may adjust to other memory clock rates in the system environment and support correspondingly slower clock rates. Low Voltage memory with 1.35V will be clocked at 1.5V when mixed with 1.5V memory using the fallback option present in the memory.

Memory configuration for good system performance:
Distribute the memory evenly across the memory slots and evenly across the CPUs. If more than one CPU is present, the memory should be configured identically (mirrored to the other CPU) per CPU.
