Overclocking and power consumption
Overclocking and power consumption
What a lot of you do not realize that overclocking a processor can consume heaps of wattage. We put this to the test by monitoring power consumption with the processor in it's default setting and then compare to an overclocked 4,2 GHz configuration. Check this out:
Power Consumptionidle
100% CPU load
Core i7 870 default100
172
Core i7 870 (4.0 GHz) 1.35v119
296
The results are substantial, when we stress the 4 (8 threaded) CPU cores 100% at default (Turbo on) we peak to only ~172 Watt for the default clocked Core i7 870.
But once we overclock towards 4.0 GHz ... the power draw all of the sudden nears 300 Watt (!) once we stress all CPU cores 100%. Stuff to think about before you start to overclock as the color green really goes red.
Enyway enough about overclocking. have a look what we did with the memory, based on an XMP profile ... very easy to configure.
And here are a few pointers we compiled for a manual overclocking session, have a peek.
