you mean on the running mode? while putting the DDR3 1333 the system automatically restarting & restarting without any display. Are you suggesting to remove the battery & put again after 30 seconds in this type of running mode?
 

With your machine OFF, remove the CMOS battery from the motherboard. leave it this way for at least 30 seconds (I'd give it 5 minutes, you got lots of time, right?) then replace the battery. make sure that it is in the same polarity as when you took it out! Now, try to power your machine "ON".
