Save right as you get off the elevator if you want to go for Overclocker. 70 Seconds is very fast on this level and you have to get everything perfect so you'll be re-loading once you've got it figured out to go for your best time.

Immediately place a BLUE on the ground in front of you and then a ORANGE on the high wall behind you as you come in. Drop through the BLUE and out the ORANGE and then back into the BLUE to fling yourself across to the Cube.

Drop a ORANGE on the bottom of the pit and grab the Cube and drop down and through. Then hit the Faith Plate and launch to the left ledge. Use the Cube on the far right to block the beam.

Place a BLUE on the wall near the Faith Plate and then drop down and launch yourself with the Plate. You'll go farther this time because of the beam being blocked. Hit the switch and then place a ORANGE on the wall. Look back the way you came and grab the Redirection Cube out of the air. Drop down to the first ledge and place the Redirection so that it goes through the BLUE and out the ORANGE on top to get the receptacle.

Go inside and put a ORANGE portal to the left, dropping you down again. Finally put another ORANGE portal to the right at the end to drop you down a final time and grab the Cube. Then walk through the ORANGE to get back to the begining.

Place the ORANGE high and to the right to make a bridge to the left platform. Go through the BLUE and walk over to the platform. Drop down and place the Cube on the switch.
