[O/C]Downcore That CPU

Downcore That CPU
by Dolk


Quote:
In the later parts of Summer 2009, I was in an overclocking competition. Someone was talking about lowering the number of cores so that they could increase the overall speed of the CPU. This made sense, sort of.

Let's say you have a Phenom II 955 BE clocked at its max water-cooling overclock, which is roughly 3.8 GHz. The current voltage setup for the CPU is 1.55v on the CPU with a 2.7 VDD. The CPU-NB is at 1.35v with a Frequency of roughly 2.8 GHz. If you were to disable a core so that the CPU was now a hypothetical “720 BE”, you would think less voltage is required to get the same speed.

In theory this makes sense, but in reality it really didn't work out this way...
