Here's the question I just cannot find the answer to anywhere : Does Turbo Boost increase just the frequency or the voltage as well? I have no experience with i5's or Turbo Boost (currently have a 4.2GHz OC'd i3 530), and have read a couple of comments that say enabling Turbo Boost causes the voltage to auto-increase (even when it isn't needed) as part of the Turbo Boost's auto-overclock feature. Being a non-"K" chip, it will need Turbo Boost enabled to do this. Its base clock is 3.2Ghz but from what I understand, with the +4 bins limited overclocking + Turbo Boost, it would potentially have a max OC of 4.0GHz (3.6Ghz Max Turbo + 400Mhz), which is just about perfect for my needs (a 4GHz i5 at the lowest possible voltage). I'm not interested in heavy OCing beyond 4GHz as the focus is on a balance between a mild overclock and low heat & noise. I'm thinking of buying a cheap i5 3470 for a HTPC build. Hi all, first post here, and I could use some serious advice.
