Cisco - 3600 Series Memory Options and Configuration Guide - http://www.cisco.com/en/US/products/hw/routers/ps274/prod_bulletin09186a0080 091f70.html
>From the section "General Guidelines" "... For 64-bit mode operation on the Cisco 3640 the following DRAM rules apply: 1. The SIMMs in sockets 0 and 1 must be of the same size in megabyte, and have the same access time in ns. 2. The SIMMs in sockets 2 and 3 must be of the same size and also have the same access time in ns. 3. The size of the SIMMs in sockets 2 and 3 must be less then or equal to the size of the SIMMs in sockets 0 and 1. ..." Regarding #3 (above) you have 16MB in slots 0/1 and 32MB in slots 3/4. Try moving the 32 MB sticks to slots 0/1, and the 16 MB sticks to slots 3/4. Marvin Greenlee, CCIE #12237 (R&S, SP, Sec) Senior Technical Instructor - IPexpert, Inc.

The current system memory configuration is: SIMM 0 SIMM 1 SIMM 2 SIMM 3 -------------------------------------- 16M 16M 32M-DUAL 32M-DUAL Use "meminfo -l" to see the valid configurations. ERROR: Illegal system memory (DRAM) configuration.

Unable to boot due to illegal DRAM configuration - aborting +++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++ i tried the same memory with other routers and they work fine. BUT THOSE ROUTERs HAVE DIFFERENT MESSAGE IN THE BEGINNING which is "Main memory is configured to 64 bit mode with parity disabled" i think this (32 bit) is the main problem. is there any option so that i can convert that 32 bit into 64 bit? anybody pls help me out of this situation.
