[TechARP] Reducing Power Consumption of OCed PCs

Now, that must sound pretty inane. Overclocking a PC seems to be as far apart from power saving as it can get. After all, overclockers employ all kinds of power-guzzling methods to improve their CPU's overclockability, from increasing the CPU core voltage to employing more powerful cooling systems. Even the act of increasing the clock speed increases power consumption.
Having overclocked all my PCs for the past 10 years, I am one of these overclockers. I have overclocked everything from a 300 MHz AMD K6-2 processor up to my current gem, an Intel Core 2 Duo E6850. I've even gone to the extent of water cooling almost every processor I've owned since the year 2000. So, the decision to reduce power consumption would seem insane, even to me.
However, there are a few good reasons why I would want to do this. Even though I love overclocking my PCs and making them run to the best of their ability, the increased power consumption has resulted in :
  • A very hot room, especially in the afternoon!
  • High electricity bill.
In these days of global warming and rising living costs, things can only get worse. Thus, the time has come to reduce my overclocked PC's power consumption. This is the premise for my guide. The point is not to make your PC the most energy-efficient PC out there, but to help you rein in energy costs and high thermal dissipation while letting you enjoy your overclocked PC. Best of all, these tips won't cost you a single cent!

Increasing the voltage by 500 MHz to 3.9 GHz would result in additional power consumption of 18 W
Bwah? He measures volts in MHz?

Com'on, it's only human to make mistakes. I think you understand what he wanted to say, let's not bash an article based on that.
What do you say about this part?

For those who are worried about the spiralling cost of electricity, this tip alone can save you quite a bit of money. Using my overclocked PC as an example, enabling EIST or C1E would save me about 13 kilowatt-hours of power a month if I just run the processor at 3.4 GHz without overvolting. When running at full 3.9 GHz, I would save about 26 kilowatt-hours a month. Sweet!

Hmm. Some of the more technically knowledgable users over at the DFI forum actually recommend turning on C1E. I'll have to try this when I get home - summer's right around the corner.

However many many folks cannot, simply because the board / CPU doesn't play well when overclocked and certain power saving features are enabled.

K, you're right, but still. My electricity costs .09 per Kilowatt-hour. So in a month I'd save between $1.30 and $2.60.
