Intel Haswell 4670k + 4770K Overclocking guide

[xxmoney96xx]

Your best bet is to find something from the Cooler Master Hyper lineup, Hyper 212X or the 412 Slim would do the job even for 4.4 Ghz (if it doesnt need absurd voltage)

 

 

I ran the stress test overnight 9 hours, I guess it's stable.

 

 

Now I will try to decrease cache voltage below 1.25v

 

I was thinking about something along the lines of that. They are cheap, but just a bit noisy. But, as I said, I'm sure that can be fixed with god thermal paste and good fan speed controlling.

 

EDIT: Anyone have a OC preset around 3.8-4.2 Ghz that is stable and doesn't run to hot?

Hey ProKoN, I've noticed that my CPU Voltage keeps going higher than it should, but doing some heavy workload with web/gfx design stuff, have a look:  

 

Why this could be happening?

[Flyingtreks]

Hi, Just to check. I have the MSI Z87i, I can't seem to find Vring. Does it not come with the Vring setting? 

 

Thanks

Some call it Ring some call it Cache.

Hmm... my 4770K is at 1.312v at 4.6GHz

Is your voltage in BIOS set to adaptive? That should be the reason why your voltage is going up.

Thanks 

what voltage are you looking for?

 

there are 3 main voltages

 

1-cpu Vcore

 

2-cpu cache voltage ( also referred to as Vring ,ring voltage, uncore voltage, cache voltage)

 

3-Processor Input voltage PIV ( gigabyte actually calls this Vrin voltage)

 

Im assuming your looking to find #2 the cache voltage?

 

can you please post screenshots of the voltage input section of your bios.

thanks

are you an a stock cooler \ not overclocked?

 

what board are you using?

 

what programs are causing the voltage spikes?

 

Install intel XTU to monitor frequencies\cpu vcore voltage

[jak3z]

I'm using a thermalright archon with 2x TY140, Asus Maximus VI Hero, and I don't know what program is causing it, it's random.

 

I'm the guy that was doing the 4.4 Oc with 1:1 ratio some posts ago that told you I had this issue with BF4 as well.

 

IXTU doesn't give me real time cpu vcore voltage.

Hi, 

 

 

 

 

Apologies, i'm unable to find cache voltage or Vring. I do see VCCIN which I'm certain is PIV but how do i change the voltage for Vring to increase my ring bus voltage. 

 

 

Thanks

You are right!

 

there is no option for you to increase the ring voltage and your on the latest bios.

 

from what i have read the z87i has limited overclocking features..

 

my best suggestion is downloading and installing XTU. perhaps it will let you tune the ring voltage from your os...im not sure.

Hi, will the settings on XTU stick throughout a restart ? Anyway, Is balancing the NB necessary for a good OC as in 1:1 or within 100-300mhz from core speed?

getting the ring bus as close to a 1:1 ratio is best

 

the reality is the majority of people will run the ring bus at stock or within 100-300MHz of the core speed.

 

for any given frequency your cpu will have the best performance\ watt ratio with the ring bus setting preferably as close to 1:1 ratio as possible.

 

dont fixate or obsess over a 1:1 ratio.

 

xtu will typically load the last successful settings automatically after a restart, but it is something your gonna have to try and report back with your findings.

 

question

 

after watching @LinusTech video comparing your board the msi z87i to the asus maximus extreme were you under the impression your little board had the same overclockability as higher end boards?

[jak3z]

So far this is the lower I could get the Cache Voltage and PIV.

 

PIV: 1.75v (under bios)

Cache voltage: 1.180v 

 

I'm also trying to overclock my RAM, but not so succesfully, this kit is very very bad sadly, other can go 9-9-9-24 at 1.7v (2000Mhz) I need 10-11-10-28 1.7v (1800Mhz)

good job on the voltage reduction!

 

overclocking ram can be fun but has little to no real world benefits.

 

i still have no idea on why your getting overvolting. i have been running bf4 the last few days without any overvolting occurrence, yes im on adaptive voltage as well.

I think something is using AVX/AVX2 instructions sometimes and thats why I get the random overvolting No worries, temps are fine so... 

I will try and reduce some more the cache voltage, I will try to make it even with the vcore just for... fun

Nice and very complete guide thanks mate keep going

 

 

 btw haha

 What a wonderfull world.... but Intel Ask for 3 years of expertise minimun... haha can be easily called Intership which can be easily called slavery!!

Looks like I'll have to do a delid to push it further. Batch# L310B492 Malay

what cooler are you using?

 

bringing down your max temp wont always yield higher frequencies!

H100i with the thermal compound that was pre-applied.

Edit: should also mention that it will do 4.7 but it gets to hot before it has a chance to crash. Don't wanna keep running it at 100 so i stop the stress test.

[Noelany]

Hey everyone and ProKon especially.

 

I've been reading this thread for about a week now and been watching everyones experiences and such and decided to give it a go, bare with me im new to this stuff. Altho im shooting only for 4.3Ghz with my 4670k i've got to stay this guide is rock solid and spot on. my chip wasn't the god chip unfortunately tho, im standing 6 hours stable with IETU (2 splits first 4 hours and now ongoing 3+) @ 4.3Ghz, 1,2660v and rest just as you descibed VCCIN@ 1.9 and Rams at 1333mhz@ 1.5v, cache being 38x for now. Here are some of my screenies I took about temps and stuff.

 

Btw does it make a huge difference if I do stress tests as splits, like i've done now or should I just aim for one stretch?

 

 

Comp specs if interested:

 

CPU: 4670k

GPU XfX DD r9 280x

Mobo: MSI Mpower SP

Ram: G.skill snipers 1866 2x4gb

Case: Corsair 750D

Custom loop with single 240 rad

 

EDIT: Crash @ 7hours ish @ 1.2660 so 1.27 goin in.

 

EDIT1: Was stable for 2+9hours with 4.3Ghz@ 1.27, but crashed after couple hours of BF4 suggestions?

[iamjustme]

I'm replacing my motherboard, can I use the same settings on the new motherboard? thanks

hard to say

 

in theory if your using the Same board the same values should transfer over.

 

If you bought a different board you may or may not have the same results!

Hi everyone and hello ProKon!

 

I'm a new Overclocker (at least I'm trying to be...) iv'e followed step one of this guide, I didn't manage to get stability

 

my last try was for 4.4GHz @ 1.32V

 

Ram was at DDR3 1333 but i got a low voltage so I didn't changed the volts (1.35V)

 

the ring bus was at 3000MHz and everything else is on auto..

 

That was the first time my OS booted up but it crashed after ~10min of stress test with IETU

my temps was as high as ~82⁰ C (during the 10 min stress test before it crashed)

 

* when I stress test at stock frequency I got a top temp of ~62⁰ C at about the same room temps

 

what should I do next? should I go for a higher voltage? the guide max volt for this frequency is 1.32V, and my temps are getting high...

 

Is this mean that I cant get to 4.4GHz? 

 

 

 

my spec:

 

CPU: 4770k

GPU: gtx 780ti Gigabyte WF 

Mobo: Asus maximus VI Hero

Ram: Crucial Balistix sport 1600 2X8GB

Case: Fractal design arc XL

Cooling: Cooler Master hyper 212 EVO (1 stock fan but soon with 2 nf-f12!)

 

 

 

 thanks for the great guide and help!

increase voltage by a bit more.. 

I think you'd get stability at around 1.28 - 1.29 volts on yours personally since 1.27 can almost handle it, though these chips are unpredictable and I could be wrong.

are you on the latest bios for your board?

 

1.35v @ 1333MHz should be fine but I would still set the memory at 1.5V to be certainits not causing any issues.

 

What is your PIV set at?
