I am sorry you are having problems with the system but let me help you.
Turbo Boost is always enabled by default on Intel® processors so I find very strange this situation with your product.
It is also important to say that the clock speed reached when using the Turbo Boost depends on many factors such as Cores running, temperature, voltage, etc.
Here you can find more information about this technology and the chart for the Turbo Boost Table on Intel® Core i5, Intel® Core i3, and Intel® Core i7 processors.
Bought this machine brand new still-in-shrink-wrap from a brick and mortar store so no doubt about it being new. One thing to note is I did update the BIOS as soon as I first powered the unit up (from 0021 to 0026). Maybe that did something it shouldn't have.
I am aware of what Turbo Boost does and the clock speeds that it can achieve (I've been able to get a Pentium 4 to do similar things by changing power settings on Windows 7 before, but I would assume Turbo Boost is more efficient with power than the previous generation processors).
Either way, many thanks for the heads-up Kevin.
