Everyone here knows what undervolting is. Manufacturers put their voltages usually little too high for stability. But this comes with excessive or unnecessary heat dissipation.

For example these cards:

HD5470 1GB - Stock 1.12v - UV 0.96v
GT-525M 1GB - Stock 0.95v - UV 0.85v

These are a few examples of extreme undervolting while being able to maintain the stock clocks as well. These solutions can save 40C!

If you have a 525M or HD5470 I would like very much to mod your VBIOS.
