2500K turbo boost overclock

I would set the voltage to manual as I think the auto mode over compensates a bit
and you are never sure just how much you are getting. The more you clock it the more it compensates as well.
My 2500K is set at 1.25v and 4.5Ghz. nice safe setting and am happy with it :)

upto you mate some people have it in turbo mode all time :P

i keep the speedstep on, to step down to 1600mhz when idle , keeps things cool,
uses less electric aswell i think :P

there normally option in bios saying something like "INTEL speed step technology" i kept mine enabled.

still cant seem to get 4.5ghz stable : /

@Khaan! you are on 1.336 voltage so not stock :P but still good mate :)

it;s called CE1 state on gigabyte motherboard and i can already see the impact it's having on my system, like everything takes that extra second longer =[
 
I've left C1E enabled with EIST (which in turn enables Turbo Boost as it's hidden with EIST turned off).

I've noted now my CPU goes to 1600MHz when idle or just browsing the web and ramps up to 4.5GHz.

I did some new tests using Aida64 benchmarks and created a report of before and after and the results are exactly the same so there does not appear to be any impact using Turbo Boost/EIST on Sandy Bridge and I;ve not noticed any apps loading a second slower and I have Aida64 benches, Fritz and SuperPi figures to back this up so I am now a happy chap!

Strangely setting the vcore manually to 1.25-1.27 v (goes to 1.256 after vdroop) I get hard lockups when doing something system intensive so have taken the vcore to auto again. It might overcompensate but my system is rock stable on auto so I will leave it at that :)
 
i 100% agree with gazzer 21

take it off auto, run prime 95 for 1 hour to check stabilty

you've tried 1.27 maybe try 1.28 first if ya want,

i've given up on 4.5ghz, got rock solid 4.4ghz stable at 1.3v :)

are temps ok?

Yup no problems with temps^

The HIGH temps listed by Coretemp was during a gaming session last night, it drops to 55 instantly after exiting game then settles to idle temps. I have the CPU fan fanmate controlled to about 65%

At least with AUTO I can be confident if it comes to it the mobo will ramp the vcore a bit more to cope without crashing.
 
what game were you playing ? 79C??

thats some very high temps for gaming ,but still safe,
the chip starts to throttle back at 90-92 i think,

have you checked what your voltage goes up to whilst gaming?
are you using the stock intel cooler or an aftermarket cooler?
 
I tell a lie, it was gaming AND I ran some Intel Burn Test runs last night too lol

The voltage goes up to about 1.36 during full load, L4D2, for example, takes each core up to about 85% during a horde segment in a vs game but that is multicore optimised so should do.

I'm using a Zalman CNPS10X cooler with AS5 paste but I am running the fan at about 65% as I prefer quietness so the temps are expected. At full speed the temps are in their low 30s idle and low 50s under load.
 
guys should i be worried???

i mean temp wise ignore that 1.6 Ghz on the left
and my vCore is just not going above the 1.224V even though in bios i have set 1.300V

That's up to you :p People have their own stbaility periods, some do 12 hours, some do 3 hours etc.

I just play Left4Dead and use my PC as I normally would. if it crashes then I get back in to the BIOS.

well i had prime on for 1 hours and a bit and ok i'll try left4dead 2 now

temp is not going above 60C so it means it's all good?
