Another 4770k overclock

[SunshineSC]

Hey guys, i have read a lot of overclocking tutorials about 4xxx intel cores.

 

But with all the variables like VCCIN multiple voltages on core an ring etc... i am unable to do a good overclocking. I dont know why i am not unable to perform a good overclocking without crashing randomly. Even at 4.4ghz and 1.4 vcore i still crash randomly. But i manage to boot at 4.6 ghz with 1.35 vcore.

 

I think i miss something important that can improve the stability.

 

So, i am asking you for help. Curently i am at 4.2 ghz with rock solid stable overclock :

As you can see i have let the voltages and multiplier in modes that reduce energy consommation alongs with c-state.

 

I am custom looped watercooled with 2 gtx 970 OC @ 1.5ghz and an equivalent of 5 120mm of radiator.

With 1.225 vcore the temps of the cpu are around 60 on OCCT.

 

Thank you for reading and for the eventual help

too high voltage can cause stability issue too. what mobo you using btw?

[Lays]

If you want to go for 4.4 ghz, do 1.25vcore, 1.915 VCCIN, try that it should work.

 

 

Most likely your VCCIN is to low and it's causing the crashes, rather than the vcore being to low.

disable intel turbo btw.

Hi, thanx for the reply. I am using MSI z87-gd65 gaming MOBO.

 

If too much voltage can cause unstability that explain a lot ^^

Ok let's try 4.4 at 1.25vcore and 1.915 vccin without turbo boost.

 

BTW thanx for the quick reply !

well, after 2 mins of occt i get a whea uncorrectable error.

 

I dont know what it is, i know clockwork error is about the vcore but whea...

 

with these settings temps are 65 celcius max.

I found chrome to produce the BSOD. Last time chrome produces GPU crashes .... Come on google !

 

Anyway, now i have OCCT making duck sound and detecting error on core 2... Any advice ?

 

No crashes is a good begining thanx !

 

EDIT : 

I was getting clockwork BSOD untill i reached 1.27 vcore (1.3 because it crank up automatically).

And now i was able to run OCCT for 5 mins without problem and 75 celcius max.

 

Thanks for the help.

 

What is the VCCIN for 4.5 ?
