Why does everyone with i7 run turbo mode?

doz · Jul 27, 2009

Just curious. I understand the whole higher speed on single threaded app's, but if you are running 4 cores @ 4ghz plus, theres really no need?

I see everyone posting up CPUz shots of like 4.4, 4.5ghz w/ 21x multi, but thats really not the "true" overclock of 4 cores and can be very misleading.

Just curious on other peoples thoughts.

Because I can get 4.2 GHZ absolutely stable at 20X133 with turbo @ 1.3v and it take 1.375 to get 4.2 without turbo. Less volts equals less heat with the same power when it kicks in.

Not the same power, as only 1 core is at that speed, not all 4 cores.

Mines en route I guess, I was curious about that one myself, but will have to play around a bit I suppose.

Seems a lot of people on extreme messing around a little someone had even cross flashed a bios to get 21 stable, but I'm not sticking my neck out like that atm heh.

It can drop 2 cores and boost up the other 2. i dont think the architecture allows for that while the system is overclocked though. i would think turning it off would add some stability.

Meh, I've never even touched that option. There's no need.
With a fully HT'd 920 perfectly stable at 4GHz what's the point?

That's a good point. With Turbo, you have to activate Speedstep. If I turn off turbo and just run at 4 GHz all the time, I can bump the voltage down to
1.25. A 50% o/c with hardly any vcore increase is good enough I guess.
