all serial interface with default config,
1T on 3620 :
sh ver
Serial0 is administratively down, line protocol is down
Hardware is HD64570
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
Keepalive not set
Last input never, output never, output hang never
But:
1T on 3640 :
sh ver
Serial0 is administratively down, line protocol is down
Hardware is HD64570
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
Keepalive not set
Last input never, output never, output hang never
3640 display BW with 2048 Kbit,while 3620 is 1544 Kbit!can anyone tell me why?

In both the routers,
1.Which NM modules are using ?
2.What is the IOS version ?
3.What type of WIC cards ?

The bandwidth parameter can be set using the "bandwidth" command in interface configuration mode:
test#sh int s0/0
Serial0/0 is administratively down, line protocol is down
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
...
test#conf t
Enter configuration commands, one per line. End with CNTL/Z.
test(config)#int s0/0
test(config-if)#bandwidth 1984
test(config-if)#^Z
test#sh int s0/0
Serial0/0 is administratively down, line protocol is down
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
This parameter does not reflect the acutal available bandwidth, it is just a value used in (E)IGRP metric calculations.
