Intel Haswell 4670k + 4770K Overclocking guide

[ProKoN]

I got Liquid ultra for under the IHS and shin-etsu g751 for the h100i as it was the brand corsair recommended.

 

 

i might give some of that cool labs pro a try out.

 

glad to hear the de-lid went good.

 

give us some cinebench results at 4.7 \ 4.8Ghz if you can. the more entries the merrier.

Will do. The liquid ultra costed me $20.59 CAD from the cool labs site after exchange rate and shipping. Took two weeks to get here from Germany.

you can try to bump up vccin to 2.0-2.2V see if that helps.

 

x101 means you need more vcore typically.

 

Glad to see the L360 install! thanks for the pic

 

you must be pushing max temp around 1.4V

 

I've push all the voltage, VCCIN 2.2, vcore 1.4, make uncore 1.4 as well.  just to get 4.5 stable, but i still get 101 instead.

in the first posting you make some note that is not recommended going over 1.45.

 

Can i make something with the RAM setting? currently using XMP 2400Mhz profile, all set per manufacture setting 10-12-12-31 2T and 1.650v

does lowering the RAM to 1800 or lower can stabilize cpu?

 

is that mean i got bad chip or just voltage hungry? and i only can push up to 4.4G ?

I'm posting to get some opinions about my current 4770K and see if the time investment

is worth while or I should look to but another to play with.

After reading ProKon's guide and setting up a 4.4GHz @ 1.190v with all other settings

to default/auto, my chip will boot into Windows 7 Pro and run 5 min. of IETU (61C average)

with out freezing up or blue sceening.

In your opinion, would this indicate that this chip is a top 60%?

I know your supposed to run 8 hours MINIMUM, but I just don't care to waste my time

with a dud chip! I'm a patient man but not for poor results.

 why are you at 1.19V

 

the guide suggests  1.25V as a starting point.

 

no idea how good or bad your chip is until you begin pushing it.

 

Welcome to the forum and TY for updating your sig

That voltage is lowest that 4.4 would boot @

I have a 12 hour test going on right now, I'll know in the morning if

that voltage will be stable, 6 hrs. and 28 mins. left, highest temp 62C

fingers crossed...

keep us posted! preferably with screenshots!

sorry, adjusting memory will not help you in anyway. that is stuff you have heard on the internet. keep your ram at 2400MHz reducing it will not help

 

x101 is cpu vcore

 

i suggest a max voltage of 1.45V on the guide yes. you are more than welcome to push past that if you like, its fine but i can not recommend it.

 

exposing your chips to 1.5V or higher will likely degrade your chip faster.

 

who knows how long that might take. may take years to happen.

 

you have a voltage hungry chip my friend, she likes her voltages doesnt she.

nice start.

 

you have lots of headroom to push for 4.5 or higher

 

is that lowest voltage for 4.4?

[BigDave]

Thanks for the posting advice, I fixed it!

Have not tried lower voltage yet, setting test to run over night.

lowering by .01 volts until it will not pass, thats correct way right?

Did you notice the discrepancy for cache ratio between CPUz and Tuning Utility readings?

i see a difference of 2.3MHz , I wouldnt sweat that big D.

 

I usually go low and work my way up.

 

maybe try 1.150V and start working up

 

Your chip seems average, maybe slightly above average

[BigDave]

I have cache ratio set to auto in UEFI, CPUz shows 3897.7 (NB freq)

Tuning Utility shows 44 in static mode (with UEFI set to Auto) with a static voltage of 1.25 which is also set to Auto????

Some standardization between manufactures would make this a whole lot easier :huh:

lol

 im a noob, i thought to myself   "dude has a prety good oc, both cach and core are at 4.4GHz..nice"

 

your right cache is set to 4.4 at 1.25V but both cpuz and xtu show 3.9

 

did you set cache in the bios or are you tweaking the values in xtu?

 

could you please post a screenie of the "all controls " tab in xtu please.

 

Im not familiar with asrock, sorry. im fairly fluent in msi , gigabyte and asus

[ProKoN]

well your cache is running at 3.9GHz for sure, just an xtu error

 

only have seen this with asrock, on your build lol

 

I agree about the standardization

[BigDave]

I agree about the standardization

Since my mobo is "digitally challenged", I just went ahead with manually setting the cache

ratio to 39 and static voltage of 1.16 for both core and cache. Came home from work and

it was still running (14 hrs.). Took screenies and then set up another run, raising the cache

to 40 for an overnight run with same voltage (1.160v)

If I can eventually raise the cache to 1:1 at 1.16 I will be very pleased indeed :-)

Ok, I've just started out with my overclock. I built my system about 6 months ago but not got round to overclocking it. It's been really good though as i can run it without turning any fans on while i'm doing anything but gaming.

I've only done quick tests so far, but i've just bumped up the multiplier and voltage. I get around 4.6ghz at 1.22v but it takes 1.34v to get stable for a 5 min stress test at 4.7ghz. Memory is at 2133mhz. Here's a screen:

Is there anything i can work on to get it more stable at a lower clock, and should i be bumping up the cache speed over 4ghz too?

I can probably get much better temperatures too. I don't have my temp sensors in the right places at the moment, so the fans don't speed up fast enough when it gets hot so that's why i get around 87 degrees. I can expect much lower when i get them sorted.

I take it that this is a decent overclock then? I've tested in cinebench and i get 929 points.

thats a nice little oc you got there

 

get core stable for 8+ hours of stress testing, 5 minutes is not enough.

 

getting uncore as close to 1:1 ratio will maximize your performance \ watt

 

you are basically very close to running out of thermal headroom at 87C, if you cant get stable drop back to 4.6GHz

 

be sure to submit your best cinebench result! link provided in the OP

Yeah 5 mins is definitely not enough I just spent a few hours working on it to get it stable at the max clock for at least 5 mins. I think i'll stick with the 4.6ghz so it can stay nice and cool most of the time

I get around 919 in cinebench, and i'll post up my score later on once i've had time to do more testing. I think that's enough for today

Change my chip, and got very good result this time.

Core 4.5Ghz@1.27v, Uncore 4.5@1.27, so its 1:1, VCCIN 1.9

 

Max Temps 85 (i haven't delid) but i use Cool Laboratory Liquid Ultra.

 

Posting my result

Thank you for the update!

 

Wow night and day difference between chips eh?

 

Nice little 1:1 you got going there!

 

Be sure to submit a stable result in meltymoons DB and post your best Cinebench results in Jumpers thread ( all the info is in the OP)

Hello,

First of all great guide and a great read through all the helpful posts!

I felt the need to create an account here as i just had a go at overclocking my new 4670k in my newly built rig, and this is where i got the most help to get stable at 4.4ghz.

Im fairly new to overclocking and sadly I got one of those voltage hungry chips that wants to put up a fight. Ive been through so many guides and different bios configs over the last days that im almost burnt out.

But thanks to this guide i was able to reach 4.4ghz on my chip with a gigabyte z87x d3h mobo.

I really had to push the voltage to get there with this chip and its now sitting at 1.285v in the bios. Though HWmonitor show VID at 1.286 and it shows vcore at 1.296v under stress tests for some reason. I also turned off everything that could effect the vcore but no change. Not that it matters because i suspect that the 1.296v vcore is what is needed for stable and i have tuned the vcore with this in mind after discovering it.

My uncore is at 3.5ghz and 1.20v. I'll try to tweak this later on. So far I've established that i cant do 1:1.

My vrin is at 2.020

I've done a 8 hour XTU stress test and also a 10 hour Aida64 stress test as well as several 10 round standard runs in Intelburntest for quick heat and initial stability tests.

Max temp in XTU was at 76c. In Aida64 max temp was 84. And in intelburntest it varies a bit but 87c i think was the highest. My cpu cooler is a Corsair h100i set to exhaust in a Nzxt h440 case.

My initial goal when starting out was an oc at 4.5. But because of the chip being voltage hungry, and with the heat that follows, my cooler isnt fit to the task. Im quite happy with 4.4 with the situation being what it is.

Also i think the sweetspot for my chip is at 4.3ghz because that required way less vcore. I think it passed intelburntest at 1.175v....

So again, thx for the great guide. It really helped me!

Since I am super lazy, has anyone reached 5GHz on Haswell 4770k yet?
