Overclocking: Dual- vs. Quad-Core CPUs

Overclocking I - Quad-Core Q6600 At 3.00 GHz

As mentioned above, our Intel Core 2 Quad Q6600 also uses the G0 stepping. Its stock clock speed is 2.4 GHz, which requires a comparatively low core voltage of 1.3125 Volts (the lowest core voltage available for this device). With any luck, this low-voltage value will be conducive to overclocking.

The Q6600 also uses a locked multiplier.

The Q6600 running at 3.00 GHz

We were unable to reach 3.00 GHz with our sample, at stock voltage. Thus, we were forced to increase it by 0.005 V to stabilize the processor at this frequency.

The memory runs at DDR2-833 with these settings

It may seem like a negligible bump, but in the end, that's what it took for our sample.

Running on a front-side bus of 333 MHz (1333QDR), the memory can run at a speed of DDR2-825 using the 2.50x memory multiplier.
