1. Independent Channel Mode
required
required if 2nd CPU is configured
Bank I Data
Data
Data Data Data Data optional, same type in Bank per CPU
(black sockets)
Bank II Data
Data
Data Data Data Data optional, any type
(blue sockets)
Independent Channel Mode allows all channels to be populated in any order
Can run with differently rated DIMMs and use the settings of the slowest DIMM installed in the system
2. Mirrored Channel Mode
required
required if 2nd CPU is configured
Bank I Data Mirror -------- Data Mirror -------- optional, same type in Bank per CPU
(black sockets)
Bank II Data Mirror -------- Data Mirror -------- -------- not used
(blue sockets)
Mirrored Channel Mode requires identical modules on channel A / B (1st CPU) or channel D / E (2nd CPU)
50% of the capacity is used for the mirror => the available memory for applications is only half of the installed memory
If this mode is used, a multiple of 2 identical modules has to be ordered.
3. Performance Channel Mode
required
required if 2nd CPU is configured
Bank I Data
Data
Data Data Data Data optional, same type in Bank per CPU
(black sockets)
Bank II Data
Data
Data Data Data Data optional, any type
(blue sockets)
Performance Channel Mode requires identical modules on all channels of each Bank per CPU.
If this mode is used, a multiple of 3 identical modules has to be ordered.
