1.3 Options and upgrade
Second processor
The system board can be upgraded with a second processor. Only processors
of the same type may be used on the system board. The second processor must
have the same clock frequency and the same cache as the first processor.
Upgrading of the main memory
2x6 slots for main memory FBD PC2-4200 or FBD PC2-5300 fully buffered
DIMM memory modules with 512 MB, 1 Gbyte, 2 Gbyte and 4 Gbyte (single
rank).
Memory modules must always be incorporated in pairs.
The organization in six memory banks, 1, 2, 3, 5, 6 and 7 with 2 memory
modules each, permits rapid memory access with four-way interleaving.
