Spare channel mode is installed the same as performance channel
mode.
Independent Channel Mode
This mode allows the memory modules to be arranged in any order in each
channel. The channels do not have to be populated identically.
You can use memory modules with different speed ratings within a channel,
whereby the settings of the slowest memory module are used for each
channel.
All channels work with the fastest common frequency.
All timings except for the clock frequency can vary between the channels.
Always start by populating the main memory at CPU 1.
If CPU 2 is installed, the following applies:
– For CPU 2, there must be at least one DIMM module (DIMM 1D)
installed.
– The DIMM slots must be fitted in the following sequence:
