OC'ing i7 2600k questions

post #1 of 4
Thread Starter 
Hey everyone, My i7 2600k is currently at 4.5ghz at around 1.35v ( i think, at work, cant verifiy yet, will post CPUID screenshot later )

and i'm wanting to get a bit higher

I know 4.5 is a good OC, but I feel like it can do better...


I'm running a watercooled CPU and under current settings, prime95 cranks it out at only 60°c


I know some CPU's reach their max at 4.5, but i wanna see if mine can do any better.

I'm not sure what the voltage limit should be on watercooled systems, ( some say 1.4, others 1.5 )

Also, from what i understand, turning hyperthreading off, will help for higher clocks? ( basically turning it into an i5 )

1. do games use hyperthreading?
2. would the higher ghz with ht off, be better or worse than 4.5 with HT.


I was thinking of putting the voltage at 1.5, and kicking up the ghz by .25 and basically see how high it can go.

Thanks

1. Some games use HT such as Battlefield 3.
2. Turn off HT will help on temps, lower temps can help cpu run higher clock, but have to watch the voltage too.

Here is my setting, hope to give u some ideas. However every chip is different.
2600K - 4.5GHz on 1.33v. 4.6GHz on 1.37v. 4.8GHz on 1.45v.

crank the voltage up to 1.5-ish..start raising multipliers and booting..see how high you can go! :thumb.gif:
then see how high you can get stable wink.gif

Awesome info, I mainly play BF3 along with some older games, where 4.5 is crazy amount of over kill.

I'll tinker with the settings and see if i can hit 4.8, that would be super awesome, and my water loop is done very well, and shouldn't have any problem shedding off the extra heat.
