Energy usage and overclocking....

Zambini · April 19th, 2007

Can anyone lead me to a reputable source that shows power consumption of a stock vs overclocked (FSB ONLY, and Voltage uppage) CPU?

Or is there almost no change in power consumption?

Also, when U use <10% load, does it use the same power as 100% load?

During some testing last night, I ran my system at stock speeds as well as overclocked.

At stock my system used 279W (266x9 on an E6600), at 8x427 it used 306W......not too much of a difference, all things considered.

The lower the load, the lower the power usage.

OCing does not really start affecting the power usage until you start cranking up the vCore, thats why OCing alone may not raise your temps, but when you raise the vCore, your temps can shoot right up, because power usage increased.

The things that suck the most powered when OCed are the high end video cards.

Todays CPUs also have built in features that lower the power consumption (which can be activated through BIOS settings).
AS LH points out, the GPU is the main culprit in power consumption now, and is only going to get worse as time passes
