This 4GB RAM is 100% compatible with the Lenovo System x3630 M4 (7158). What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Technology:

• Board 6 Slot
• Board 12 Slot

Maximum capacity by memory technology:

• UDIMM ECC: 24GB RAM
• RDIMM: 96GB RAM
• LRDIMM: 192GB RAM

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 memory.

Principles of memory configuration:

• The memory slots are organized in groups of 2.
• The different groups of 2 slots do not need to have the same capacities.
• Only the memory slots that have the respective CPU present can be used.

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.
