Intel 2600K 4.3GHz, is this all it can do?

post #1 of 9
Thread Starter 
I have an intel 2600K with a Gigabyte Z68XP-UD3R motherboard.
The overclock is stable and works perfectly at 4.3GHz with a vcore of about 1.310 or so but as soon as i select the multiplier to go to 44 it wont boot to windows and just reset itself a couple of times before reverting to factory settings. Do I honestly have a 2600K that can't even get close to 4.5GHz ????

This is really frustrating me and I cant figure out how to fix it (if it can be fixed).

In bios i always have the following disabled:
-turbo boost
-CPU PLL overvoltage
-C1e "enhanced halt"
-C3/C6 support
-EIST (i think this is the speedstep).

Can anyone help me with this?

More vcore

Not all 2600ks are the same.

I have (almost) the same as your mobo, along with a 2600k, I couldnt boot normally until i set the vcore to 1.350 at 4.5ghz, so definitely you need something like 1.345 and more for 4.5ghz+ (try Auto vcore temporarily to see what your mobo set it for you at 4.5ghz). not all chips are the same so you have to keep messing with the vcore until you get a stable overclock, I think CPU PLL overvoltage should be enabled at 4.5Ghz+ OC as I read in another forum. AND, why have you disabled the turbo boost? Enable it! also try prime95 (5 hours+) to be sure that your OC is stable.

Have a nice OC smile.gif

P.S I still have difficulties overclocking, so am not the best in here biggrin.gif

Your going to have to use more voltage, specially if you want to find a stable point..

max voltage is 1.52 ( but don't use that much)
intel suggests 72 deg but you should be fine anything under 80
you have plenty of room for experimentation..

so start off around 1.360 and lower from there, if its not booting you need more voltage

You have to remember that every chip is different. Ive seen 2600-k's at 5Ghz with like 1.39 volts. I got mine stable at 1.43v and it runs like a beast. Just keep upping the voltage until you find a good point. Run Prime for about 4 hours and if its stable after that then your good.

Imo using prime places more strain on your pc than any game out there right now so Id say 4 hours is good enough for prime.

But thats just my 2 cents

Sorry to bring back to life threads from the world of the dead threads, but I have the exact same problem, except that I have a ASRock Z77 Extreme4 motherboard... I can't log on to windows with anything above 4.3 GHz Windows logo bootscreen just freezes, I've already tried everything I've found online but haven't been able to find a solution. People just say "some chips don't overclock well..." and such. Even with everything on Auto, the damn thing don't go past 4.3. I'm currently running 4.3 with, I think 1.315, with idle temps between 30-35 and while gaming, 50-55. Prime95 gets it up to 73 or 75, which, imo, are pretty resonable...

So, any ideas, questios, suggestions and I accept money to buy a new chip too!! LOL

Turning CPU PLL overvoltage ON helps me with exactly that (booting on > 4.5 GHz) on my Asus Z68.
