This 16GB RAM is 100% compatible with Dell PowerEdge C6220 II. What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Technology:
Maximum RAM in GB with 1 CPU:

• RDIMM 2Rank: 128GB RAM (8 x 16GB RDIMM)
• LRDIMM: 256GB RAM (8 x 32GB LRDIMM)

Maximum RAM in GB with 2 CPUs:

• RDIMM 2Rank: 256GB RAM (16 x 16GB RDIMM)
• LRDIMM: 512GB RAM (16 x 32GB LRDIMM)

ECC DIMM, Registered DIMM, and Load Reduced LRDIMM memory modules must not be mixed. Therefore, when upgrading, you should know which memory is already installed, or upgrade completely to RDIMM memory.

Principles of memory configuration:
There are 4 memory channels per CPU, each with 3 memory slots. ECC DIMM, Registered DIMM, and Load Reduced LRDIMM memory modules must not be mixed. When using ECC UDIMM memory, only 2 out of 3 memory slots per memory channel can be occupied. Memory slots without a processor present must not be populated.

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.
