A stock FSB clock that was already near the processor’s limit made this the most disappointing overclocking experience we can remember since National Semiconductor’s Cyrix MII. Its measly 15% gain felt like a tremendous achievement, however, considering the great effort required to reach a 2.69 GHz clock frequency.
Sandra Arithmetic and Multimedia show CPU performance gains of 14 to 15 percent.
A memory bandwidth increase of 19% looks much better, but isn’t as noteworthy in a CPU overclocking guide.
Low core voltage plus high FSB voltage brings a significant penalty in power consumption, even though performance gains were mediocre at best.
An efficiency loss of 9% results from a ratio of performance to power consumption for the overclocked configuration.
