Independent mode
This server supports independent mode only.
Independent mode provides high performance memory capability. You can populate all channels with no
matching requirements. Individual channels can run at different DIMM timings, but all channels must run at
the same interface frequency.
Make sure to adhere to the following rules:
• All memory modules installed should be identical in type and capacity.
• Do not mix memory modules with different voltages.
• Do not mix low-voltage and regular UDIMMs. (2R memory module only)
