3.10 GHz at Stock Voltage
When we overclock processors, we test their stability with Prime95 in the new version 25.5a, which comes with multi-core support. Our CPU has to make it through several test loops without crashing, freezing or the benchmark exiting before we consider it stable.
The factory-set multiplier is 13x. We started from there and increased the multiplier step by step. Initially, we did not increase the processor’s core voltage to prevent a rapid rise in thermal power dissipation and to get a better impression of the CPU’s potential.
To say we were surprised by what we found would be quite the understatement. The CPU was rock solid in Prime95 up to a multiplier of 15.5x, which equates to a core frequency of 3.10 GHz – at stock core voltage!
At this frequency, the memory was running at DDR2-775.

I usually don't make accounts like this. But for this review I really had to.
TERRIBLE REVIEW, just awful. Very poorly written (several numerical mistakes) and very misleading.
Who compares a stock E6550 to a X2 5000+ with a 1.0Ghz OC advantage?
Worst of all, do you ever mention the E6550 is at stock? No...
Bert, Bert, Bert...
