Upgrading System Memory in Cisco 3600 Series Routers

78-3636-05

Memory Configurations

–

Have the same access time (in nanoseconds).

• SIMMs in banks 2 and 3 must:

–

Be the same size (in megabytes), and the same size as or smaller than those in banks 0 and 1

–

Have the same access time (in nanoseconds)

Thus, only certain combinations of DRAM SIMMs are permitted:

• Combinations for 32-bit configurations used in Cisco 3620 routers are shown in Table 2.

• Combinations for 32-bit configurations used in Cisco 3640 routers are shown in Table 3.

• Combinations for 64-bit configurations used in Cisco 3640 routers are shown in Table 4.
