The current system memory configuration is on a router 3640:
SIMM 0 SIMM 1 SIMM 2 SIMM 3
--------------------------------------
32M-DUAL 32M-DUAL
But I'm on a 32bit mode and when I look at the supported configuration, I have :

As you can see, there is no dual on 32bit mode, how the router accept the dual mode in 32bit mode? shall I change the bit mode?
Note on SIM2 the 16M is not supported I have to add still one.
SIMM 0 SIMM 1 SIMM 2 SIMM 3

Thanks in advance.
