Setting banwidth does not set the clock rate. The bandwidth of the
serial intreface is 1544 kbit by default for Cisco router regardless of
the clock rate.
For a serial interface, it is either a DCE or DTE, DCE should provide
the clock for sync operation, u set up the clock rate at the ineterface
that connect to a DCE cable.
Show contr serial xxx will tell you the interface is a DCE or DTE and
the current clock rate if it is a DCE.
It is a good practice that you set the bandwidth at both end of the
serial ineterface
as some routing protocols using bandwidth to calculate the matrix.

whatever you assign the clockrate, that's your total bandwidth. Try to
do
tftp w/ 128k than try w/ 2048k you will see the difference.
clockrate=bw.
