The max turbo you're reporting is the chips base 4 core turbo speed. Alot of motherboards will ramp up the 4 core turbo speed to 4.4, but that's not intel's stock setting, which is 4.2 for 4 cores, 4.3 for 3 cores, and 4.4 for 1 and 2 cores respectively. If you want a higher setting, you'll have to manually take over motherboard settings instead of leaving them in auto.
