I always disabled EIST on all of my Intel CPUs. As long as your not putting crazy volts through it then you need not worry about the lifespan, also with regards to power consumption it will use more when disabled but your CPU will probably not be running at 100% load constantly anyway so the power consumption won't be that dramatic. My OC is 24/7 no power saving features, though a lot of the time I am just browsing and listening to music so its not like it's using up tons of electricity as it is.

EIST can be offset by adjusting C1E in RealTemp. Check/tick the C1E box to enable EIST so that your CPU speed wil relax to 1.6GHz or whatever lower during idle. But i dont think you would do this on every reboot.

weird, since you have set back to default settings, EIST, C1E, C3/C6 is supposed to be enabled/auto. Just make sure that:
In bios enable EIST (speedstep), C1E, C3/6
In windows, change power management to balanced or power saver.
Other than that I really have no idea already. Maybe other forumers got idea 

CPU-Z?

wait for a while. 'speedstep' wont 'kick in' immediately.

I believe there is a Thermal limit being set somewhere. Show us your BIOS setting.

By default, Intel's spec is 95W TDP, meaning if the CPU total power consumption is capped at 95W. If all four cores are active and total power utilised exceeds 95W, it will automatically throttle down the cores and run within the TDP limit.

To overcome this, you will need to raise the TDP limit, in ASUS bios this is called CPU Power Management.

Becareful though, by lifting the TDP cap, your processor will tend to run hotter.

Friend, read up on Intel Turbo Boost Technology for a better understanding on how this works.

The 3.7GHz Turbo will only work if there is one core utilisation, if 4 cores are utilised all the cores will not go to 3.7GHz, it will go to 3.4GHz instead as per design of not to exceed the TDP.

Refer to this image for clearer explanation.

If you were to manually set a Turbo multiplier, this will overwrite the default setting and all four cores will go to the turbo value you specified.

Try this.

In your screenshot #4, set C3 and C6 to Enabled instead of Auto.

*20~30% load is enough to set the processor to kick into 3.4GHz+, try closing all programmes and monitor again under 0~1% load it EIST should kick in and set the processor to 1.6GHz when idle.

im running on 4.5 only ... vcore set to 1.295 prime95 fail after 10 hour on 1.285 and 1.290.
my idle about 40~42, full load can up to 70~73

torino is the one running on 4.7 

so you mean auto oc bring you up to 4.7ghz?
