How do you fix the speed of a Core 2 Duo T7250?

[xangel9626]

I need help fixing the speed of my processor.  The T7250 has a max multiplier of 10x but in OSX it only goes up to 9x giving me 1813mhz instead of 2000mhz.  I have SMBIOS set as MacBook Pro 4.1 with SMmaximalclock set to 2000 SMexternalclock set to 200.  I have tried adding the busratio=10 but it does nothing.  I can't figure out how to do an SSDT since all the threads I can find about it only talk about I5 and I7 processors and I don't even know if I really need one.   Booting into safeboot gives me the proper speed.  It's not the cosmetic issue people are getting in "About this Mac", I'm using CPU-X to check the performance.  Any help would be appreciated.
