Download the program Real Temp version 3.40, in the zipfile there is a little application called "i7 Turbo 6.95".  This ultility has a box to check "Turbo Mode Disable" on the fly.  Don't be surprised by the constant varying multiplier or C0 state percentages, the generator never maintains a constant value and utilization varies even on idle desktop.  
 
Give this Intel info on TurboBoost a read through or watch the flash video demo at the bottom explaining the point of TurboBoost (for the majority that just don't need the speed all the time, i.e. don't care for benchmarks). 
 
Not even whichever OS, Intel decides when their CPUs use Turboboost; and while it is based on utilization of lesser threaded applications, it isn't necessarily a per program basis.  All programs have some internal subroutine that doesn't use all cores -- that's when the Turbo engages and gets those little steps out of the way, it isn't sustained throughout the program.  This could be one reason for an inconsistent benchmark score, while those of us with mere 1x-2x binning desktop i7's won't notice compared to your 7x jump.
 
I wouldn't worry too much about it.  But if it bugs you that much, I have a Toshiba laptop with a Pentium P6000 in the same mPGA988 socket, its a 1.86GHz Clarkdale dual-core with no Turbo or HT.  Although it has a powerstate I can't seem to adjust that varies from 7x to stock 14x, could just be on my laptop though.
 
Have you looked into adjusting the powerstates to affect Turbo potential?
