Find a heavily single-threaded benchmark and see if that doesn't push the processor to 3.7Ghz.
EDIT: Seeing this confirmed on other forums. Also, I see suggestions to check the "Power" settings on Windows. If it's set to "Performance" profile, Windows will try to keep all four cores ready. If you set it to "Balanced" it'll let the other cores idle down/sleep, which should allow you to get to 3.7 Ghz if you're running a single-threaded program.
Any gerbil here want to back me up on that last bit? It sounds reasonable, but I'm not 100% sure.
