Nope, that's the max Turbo so single-core. Here's a chart of theoretical max clock speeds:
Code:
CPU       Stock           Turbo         |   OC + Turbo (P67 only)
                    4c   3c   2c   1c   |    4c   3c   2c   1c
                                        |
i5-2300    2.8      2.9  3.0  3.0  3.1  |    3.3  3.4  3.4  3.5
                                        |
i5-2400    3.1      3.2  3.3  3.3  3.4  |    3.6  3.7  3.7  3.8
                                        |
i5-2500    3.3      3.4  3.5  3.6  3.7  |    3.8  3.9  4.0  4.1
                                        |
i5-2500K   3.3      3.4  3.5  3.6  3.7  |    5.7  5.7  5.7  5.7
                                        |
i7-2600    3.4      3.5  3.6  3.7  3.8  |    3.9  4.0  4.1  4.2
                                        |
i7-2600K   3.4      3.5  3.6  3.7  3.8  |    5.7  5.7  5.7  5.7
On the non-K processors, I expect you're pretty much guaranteed to get the full OC. On the unlocked K processors, I'd expect around 4.4~4.5 GHz would be safe for daily use. The Turbo chart on the left is available on both H67 and P67 chipset motherboards. The OC + Turbo chart on the right only works for P67 chipset (and later, perhaps the Z68). The numbers on the right are basically Turbo + 400 MHz OC for the non-K processors.

Lol, AnandTech was able to get to 4.4 GHz on stock cooler on their sample.

Lol, AnandTech was able to get to 4.4 GHz on stock cooler on their sample.
Nice one with that chart

When AnandTech got 4.4 on the stock cooler, was that with 1 core or 4?

Either way, pretty damn impressive ;D
