Overclocking Intel CPU's using Turbo - Overclockers method

[Ph0b0s123]

I wanted to start a thread to talk about another method of overclocking Intel CPU's.

My friend brought a pre overclocked system from Overclockers before Xmas. I was interested to see that the method for overclocking used on the system was using the Turbo modifiers.

Let me explain. The main overclocking method people are aware of, is to increase the base clock or the multiplier (for unlocked multiplier CPU's, k's, extreme editions etc) and to increase the vcore etc. Once those increases are set they are what the system is locked at. So even when your system is doing nothing, it is still running at a high frequency and vcore, generating extra heat and burning extra watts. Some people enable EIST, but the frequency and vcore do not go down as far as the CPU would, when it is not overclocked. I think of this method as Static overclocking.

There is another method that gives the same overclocks, but allows the CPU to have the same thermal and voltage settings at idle as an un-overclocked CPU. A method that overclocks the CPU on-demand dynamically. This method uses the turbo setting on CPU's after Nathelem to overclock the CPU. It is only available on unlocked CPU's that support the turbo function, Exterme Editions, K CPU's etc

Basically what you do is instead of changing the baseclock or multiplier, you change the Turbo multiplier settings. So when your CPU goes into turbo mode instead of increasing 1 or 2 'bins', it will increase by as many as you set.

Let me show some examples.

Here is my system that uses an old Bloomfield CPU on a DFI LP UT X58-T3eH8 motherboard:
Idle & Load, Turbo Multi set at x29, Vcore and all other voltages left on auto.


Not the most extreme overclock, but I'm not a record seeker.

Here is my friend's Overclockers pre overclocked system using an I7 2700K CPU on an Asus Maximus IV Extreme-X motherboard:
Idle & Load & bios setting


The only disappointing thing with the overclock is that the Vcore has been nailed in the bios at 1.384 V, which defeats the reason to use this method. I would play with my friends system, but he has warranty concerns so won't let me. Fair enough.

Anyway hopefully I have explained the method for unaware now.

So has anybody else used this type of overclocking? What sort of result did you get? Don't know if anyone from Overclockers wants to chime in as to why they use this type of overclocking over the traditional static method. This method has been around since late 2008 but only on expensive Extreme Edition Nathelems, now there are unlocked K CPU's at a range of difference price ranges, this method of overclocking is now accessible to all budgets. Hopefully we can collect some info about people experience with using it here....

I think you will find loads of people are using this type of overclocking method on these forums, me included. The advantage of this method is you are only using the extra cpu power when needed "gaming \ video editing", when running less strenuous programs the multiplier will drop considerably, so less cpu volts required, which means less cpu heat, which is always a good thing and saves a little energy.
I'm running my i7 2600k @ x43 on the turbo settings, not a huge overclock but one I've found runs stable on my setup. When under stress the vcore volts will go up to 1.25v with temp of 55-65c, when not under load the multiplier will drop to x16 and the vcore to 0.92v, temps about 23 - 30c.
Looking at your friends overclock the core voltage should not read the same, unless he took the screen shot before CPU-Z had time to settle.

I'm sure I read somewhere that when using k version cpu's you can set the cpu clock ratio higher than the standard setting, giving you the same results as using this turbo method overclock as long as you leave something enabled in the bio's, just cannot recall what the setting was called.

Good to know. Thought this might be the right place to have this topic. Obviously I search around first, but could not see a topic here for just talking about this method of overcloking. Have tried to start the topic other places, but no-one was interested, maybe due to it only working on EE CPU's at the time.

So yes please keep the details of how successful people have been coming. There are lots of examples of the result people are getting for static overclocking, but not a lot for this method.

As far as my friends PC, I took the CPU-z shots and it is definately stuck at that vcore. Which makes sense as that is what it is nailed at in the BIOS.

I use this method, an excellent way to overclock keeping all the power saving features. Set my turbo multiplier at 45x, vcore at 1.3volts cpu-z shows 1.272 volts (vdroop) at full load, and clocks down to 1600Mhz @ .960 volts at idle. I have clocked upto 4.8GHz stable using this method all good
