Address Bit Permuting and
Card to Card Interleaving
The ProLiant 6000 server offers enhanced memory performance for certain
memory configurations. By following memory configuration rules, the system’s
memory access time is reduced automatically and system performance is
improved.
NOTE
: All banks must contain four EDO DIMMs of the same capacity and
speed.
Address Bit Permuting (ABP) is an option that distributes memory addresses
across two or four banks of memory. Therefore, an ABP group may be two or
four banks in size. Below are the memory configuration rules that permit ABP.
Memory Configuration Rules for Address Bit
Permuting
■
2 or 4 banks on a memory expansion board must be populated.
■
All banks within an ABP group (2 banks for a 2-bank group and 4 banks
for a 4-bank group) must be of the same memory capacity.
■
The memory in the expansion board must be populated starting with
bank 1 and each populated bank must be adjacent.
■
Both memory expansion boards, if configured with memory, must be
configured in ABP groups (groups of 2 banks for 2-bank ABP or 4
banks for 4-bank ABP).
