Can't get past 4.1 ghz on 4670k

[sandals100]

Hi,
I have been trying to overclock my 4670k for the past ~4 weeks. I have sucessfully reached 4.1 ghz @ 1.26 volts and 4.1 ghz @ 1.24 volts on the ring bus. I have been trying to get 4.2 ghz but can't get stable at even 1.285 volts with the ring bus at 37 @ 1.220 volts. I am not willing to go over 1.3 ghz because I am uncomfortable running that much voltage into it everyday and also because I hit about 81 degrees Celsius on the hottest core. I have been working with one of the members over at Tom's Hardware but with no luck (his suggestions were a bit.....thin?). So I was wondering if there were any further settings I could alter in order to get a decent overclock.

 

Things I have attempted:

- CPU Load Line Calibration: Extreme

- CPU Current Capability: 130%

 

System:

CPU: i5 4670k

CPU Cooler: Thermaltake Water 3.0 PRO

Mobo: Asus Z87m-Plus

RAM: G.Skill 1600mhz 16GB (1.5volts)(9-9-9-24)

Graphics: Asus GTX 760

PSU: Cougar RS750 80+

Storage:

1x Samsung 840 Evo SSD

1x WD 1TB HDD

1x WD 1TB HDD EXT

1x Seagate 2TB HDD EXT

looks like you lost the cpu lottery not every chip will be able to OC allot 

[JLCitadel]

There's always the chance you had pretty bad luck with the silicon lotto.

make sure you applied your thermal compound properly, try a fresh apply,

[creativename]

You just got a not so golden chip. It happens. Just bad luck.

[TacticlTwinkie]

Seems like you lost the silicon lottery. At least yours is better than mine. I can't get my 4670k stable into windows at 4.0ghz without breaking 1.3 volts. At 3.8ghz im hitting 86 degres on the hottest core. So mine can just barely run at Turbo speed 24/7.

[sandals100]

Firstly HOLY S**T YOU GUYS RESPOND FAST. WAY FASTER THAN TOM'S HARDWARE

Secondly Dang... Meh 4.1 ghz still makes sony render faster than stock so I am happy. Anyway thanks for your time guys. And I shall try some new thermal paste either Noctua NT-H1 ($9) or Arctic Silver Ceramique 2.7gram ($5) although I am not sure which one is better.

Damn, I wish Intel would accept returns of K model CPUS that didn't overclock well.

lol, I am really not impressed with the first gen of haswell CPUs they really aren't worth the money if you got an ivy- or even sandy-Bridge CPU

Toms hardware is a joke.

Yeah I thought that in me spending extra cash on the K version I could OC better.....

They are good for somethings but most of the time you just wonder what you are doing there.

Tough luck mate, I have no idea why people recommend haswell at all especially where i'm from. The motherboards are more expensive as well here.

 

but hey, atleast you got past 4 GHz. I'm usually running my CPU at around 4.2 GHz and it's fine (stock volts), though I can push it if I do rendering or whatever. (max mine is able to achieve is 5.3 GHz on high voltages and around 4.8 - 5 GHz on ok volts)

[TacticlTwinkie]

I completely agree. If you already have ivy or even sandy, I'd skip haswell. But my previous system was showing its age. Still a nice upgrade from my wolfdale e8200.

[sandals100]

The only reason I went haswell was because of all the 'NEW GENERATION' hype. I think I could have saved some money on the mobo and bagged either the i5 from sandy or payed a little extra for the 3770k.

Lucky with the 4.2 voltages. Mine at stock draws 1.210 volts whilst I have seen people overclock to 4.4 ghz with less than 1.21 volts.. this lottery is crazy

Don't bother mate, changing the thermal compound will give a max of 4 degrees C, so there isn't really much point. Just stick with the 4.0Ghz . You're just unlucky

[Biased Opinion]

Firstly HOLY S**T YOU GUYS RESPOND FAST. WAY FASTER THAN TOM'S HARDWARE

Secondly Dang... Meh 4.1 ghz still makes sony render faster than stock so I am happy. Anyway thanks for your time guys. And I shall try some new thermal paste either Noctua NT-H1 ($9) or Arctic Silver Ceramique 2.7gram ($5) although I am not sure which one is better.

get the intel overclockers warranty and kill you chip. Then roll again.

lol then everyone would return who cant OC to 5 ghz. and Intel would Higher their prices alot because none would buy that returned CPU:D You understand the system

 

90% of the OCers would return if it cant make it to 5 ghz:DDD

[deguzi]

you're not alone in this silcone hell. even with my h110 properly mounted i can't get past 4.2 @ 1.18v. once i up the voltage to 1.2v or higher for a 4.3 OC, it hits 90+ degrees stressed. 

 

just the luck of the draw unfortunately. i learned to be happy with it 

[BrightCandle]

Its not always the core voltage that needs increasing, the uncore voltage often needs a boost as well to get the chip running. Normally they go above 4.1 before they need an uncore boost but its certainly worth putting a bit more through there. Total list of things you need to change:

 

Core voltage - up to 1.3V

Uncore - just another 10% (1.1V on my SB but not sure on Haswell).

Current capability to 130% or more

 

VRMs set to normal/none to begin with, no need to use that until your at the extreme end and almost never the highest setting as it just makes your CPU hot with extra volts.

 

Make sure to check your memory stability with memtest 86+ as well on stock and higher clocks. There is a chance the memory is marginal as well and that can often come out as a failed overclock whereas really the memory isn't quite good (I have had a lot of problems with poor memory sticks in the past).

Hmm that's actually a good idea. And its only $25 which is pretty cheap. I'll think about that one.

Oh well in that case I will just save my money and consider the overclockers warranty then.

My goal of OCing isn't to get crazy 5 ghz overclocks but more or less something reasonable like 4.4 ghz or even 4.3 ghz. Yeah I can also see what you mean, practicality issues...

Temp's aren't my problem until I hit about 1.3 volts. I can happily stick at 1.27 without breaking 74 Celsius.

My memory's stock clock is 1600mhz, without any effort I can reach 1800 mhz with timings at 9-9-9-24 and the voltage at a mere 1.55 volts.

Have you given my OC guide a ride?

I was going to do it if I got a crap chip but mine does 4.6Ghz so I'm not to worried about it.

i tried your guide but had no luck plus I was unwilling to go too high on the voltage. Thank's anyway.

Haha lucky

[lani100]

yep you had no luck on the lottery my 4770k does 4.4 at stock voltage so that's not bad
