Confused about Turbo boost actual speed

My i5_750 current clock speed is 2.66 ghz and it's turbo boost speed is 3.2 ghz.but in bios i found that it's 2.8 ghz actually when all cores are on.then i disabled my power saving features and then found in Cpu z all cores are running at 3.2 ghz.but then i started to play ACR and found that after 10 minutes cores are at 2.8ghz ...how's that possible and which is correct?is it possible to get full 3.2 ghz when all cores are active?
