In order to get the E6750, which runs at a default clock speed of 2.66GHz, 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, with the result that the processor completed our Prime95 tests without error on an FSB of 425 MHz (1700 QDR).
In this configuration, the memory was set to 425 MHz, which corresponds to DDR2-850. The memory multiplier remains at 2.00x.
We tested the processor’s stability using Prime95. Even at 3.4 GHz, our sample ran stably and flawlessly.
| CPU Frequency | 3.40 GHz (+27.8 %) |
| FSB | 425 MHz (1700 QDR) |
| Core Voltage | 1.3625 |
| Memory Multiplier | 2.00x |
| Memory Frequency | DDR2-850 (425 MHz) |
| Memory Latency | CL 4.0-4-4-12 |
