Although we rarely get the top overclock speeds out of Intel based boards (probably because of a lack to BIOS tweak options), we usually do get some good results and it is usually rather easy to find the limits of these boards. This held true for both the Intel DP55WG and the DP55KG boards. We started out overclocking using the default multiplier for the CPU, and achieved some decent results. The more expensive KG board did outdo its cheaper sibling though, as you will see.
This was with the DP55WG board. Not too shabby at all, as it is over a 1GHz overclock! But, that was just the WG board; now look at the KG board:
We tried to lower the multiplier and see if we could go higher on the fsb, but that proved to be a futile attempt, as we did not get any higher results for the fsb.
Now, as we mentioned, Intel includes what they call Turbo Boost Technology. Turbo Boost Technology allows you to run the processor core faster than
the marked frequency if the part is operating under the limits of the
Thermal Design Power (TDP). Intel has recently also released a Turbo Boost Technology Monitor application, which is a Windows sidebar gadget that notifies the user when applications request a boost in performance. We put it into use to see how it worked. The pics below show it when Turbo is not used and then when it kicks in:
