1 Requires greater than 32-bit operating system memory support,
or device driver support.
The server provides two features that increase memory access speed,
address bit permuting (ABP) and card-to-card (C2C).
Notes:
- BIOS automatically, enables ABP, C2C, or ABP and C2C together, depending on the memory configuration.
- ABP can function without replacing the terminator board with an optional memory bord.
C2C provides better performance but requires DIMMs in both memory boards.
C2C and ABP together provide the best performance.

Processor Board Jumpers
If the microprocessor bus-to-core ratio
is incorrect, board components will overheat and component damage might occur.
Be sure that the microprocessor bus-to-core ratio jumpers are properly set.
Note: The following is the correct jumper description.
(Jumper-settings found in User's Guide for 7000-M10 are incorrect - and will be changed).

Notes:
For example, if you have a 450 MHz microprocessor installed and the system bus speed is
100 MHz (the default), be sure that the jumpers are set to a bus-to-core ratio of 4.5
(450-100), refer to jumpers J43-J46 (above).
For example, if the server has a 400 MHz microprocessor installed and you install three
450 MHz microprocessors, set the Microprocessor Core Frequency Selection block for the
400 MHz microprocessor.
