a temperature cosa dice??
dai dai.. temperature permettendo mi sà che ti tocca impegnarti un pò di più, una cpu come quella a default non se può vedè, si può far nulla?
If you've played with an LGA2011 system then LGA1150 will feel quite familiar when it comes to overclocking. If you haven't then there are essentially a few more options when it comes to pushing the CPU frequency, although the core multiplier still works as it did with Sandy Bridge and Ivy Bridge. B-Clock tuning ratios have been introduced, essentially working as straps, allowing you to boost the baseclock far higher than you could previously without making your PC go haywire.
So for those that haven't dealt with straps before, the B-Clock tuning ratios offered on most motherboards are 1.0, 1.25, 1.67 and 2.5. As an example, say we set the baseclock to 125MHz - suicidal in an LGA1155 system, but using the 1.25 strap will mean your PC is perfectly stable.
Why? Well in simple terms, the rest of the system still sees this as running at the default 100MHz thanks to the strap (125/1.25 = 100). However, your CPU sees the baseclock at 125MHz, meaning a CPU multiplier of 35x will result in a clock speed of 4,375MHz (125 x 35).
Crank the strap up to 1.67, and using a 167MHz baseclock will mean yet again that your system sees the baseclock as 100MHz while the CPU frequency will be 167 times whatever your multiplier is.
However, you still can't play around with the baseclock more than the usual 5 per cent or so. For example, using the 1.25 strap at 125MHz means you're system sees it at 100MHz. However, raising this to 135MHz will result in an effective baseclock of 110MHz which will likely land you in hot water.
With an unlocked multiplier as we have here with the Core i7-4770K, there's clearly little need to do this other than fine tuning to squeeze every last MHz out of your overclock, and we don't want to speculate as to whether locked-multiplier CPUs will support this feature. The latter could open up a margin of budget CPU overclocking again, as you'd be able to significantly boost the clock speed by using the baseclock. This is something that's been missing from Intel's line-up since LGA1156. We're still waiting on confirmation of whether non K-series CPUs will be compatible with B-Clock tuning ratios. However from messages in various EFI's stating 'if your CPU supports this feature' we suspect that only a few non K-edition CPUs will support B-Clock tuning ratios if at all.
