Overclocking: Dual- vs. Quad-Core CPUs

Overclocking III - Dual-Core E6750 At 3.40 GHz

In order to get the E6750, which runs at a default clock speed of 2.66 GHz, to operate stably at 3.40 GHz, we had to increase the core voltage. We achieved this by increasing the voltage by a mere 0.0125 Volts, which resulted in the processor completing our Prime95 tests without error on an FSB of 425 MHz (1700 QDR).

The E6750 is now overclocked by 27.8%.

In this configuration, the memory was set to 425 MHz, which corresponds to DDR2-850. The memory multiplier remains at 2.00x.

The memory runs fine at DDR2-850

We tested the processor's stability using Prime95. Even at 3.4 GHz, our sample ran stably and flawlessly.
