Power on the Mac and immediately press and hold command-option-P-R.
 
The system will restart with the ‘bong' noise; allow it to do this 3 times. On the third ‘bong’ you can let go of the keys.
 
The machine will now boot with a cleared password and reset PRAM/NVRAM.
 
You can then shut down the machine and reconfigure the RAM configuration as you want it.
