Step 1: So What Is It??
Step 2: And So Why Exactly Does This Work??
over heating-> there will be some space under the board so the board doesnt get as hot
bad Ram connection->obvisouly the ram will get pressured back on to the motherboard
GPU/CPU issues-> with the released unneeded tension off the x clamps they dont seems to come unsolderd
Step 3: What You Need
various screwdrivers for xbox disassembley
Step 5: Make the penny stacks
Step 7: OVER HEAT!!!!
overheat your xbox then cool it down completely. You have 3 options for overheating. 1. Towles, Not recomended. 2. unplug the fan, Better than towles but not great or 3. leave the fan plugged in but reloate it soit cools cpu but overheats GPU. BEST OPTION.
Oveheat for 10-15 minutes then cool down.
