Hello!
Power consumption of MSP430 may be influenced by port status. Did you set
the ports in input? Output? Did you use the internal pullups?
Beside this, if you have just soldered a new chip without loading any program
in it, you cannot predict what will be its behavior. When you power it, it tries
booting. If there is nothing in the flash, I am not sure the behavior is consistent.
Try to write a minimalistic program to define its state, and measure again.
By the way, what is the voltage regulator indicator?
