4670k

[ahmed307731]

Hello peeps . 

 

 

Just jumped on the haswell gun ship .

 

 

Running a 4670k on the AsRock Z87m Extreme 4 .


Failed 1st and only attempt to update bios using bios flash utility on the board - supposedly a common occurrence with the ASRock line of boards as well as man others and yes everything was set to default with a back up and all those nice precautionary measures in place before the attempt .


Overclocking has yielded less than anticipated results with 4.2 GHz topping out my efforts at an extreme 1.26V .


Supposedly , this issue is also a common occurrence with many boards and manufacturers have been quick to release updated bios' that GREATLY enhance their specific boards overclocking potential  . 

 

 

I came across a thread where one user managed to DECREASE the voltage from 1.26v to 1.7v after successfully updating said bios (also after a few failed attempts) and achieve the same clock speed 100% stable 


I will be reattempting to brick my motherboard ,...err...I mean update the Bios using a different update method that has supposedly yielded better results (within windows executable that restarts the system and carries out the update without initiating UEFI for my motherboard ).



Currently running an overclock of 4.2 @ 1.26~ and hopefully will touch base with all of you once I see whether this holds true.


As an honorable side mention , updating the bios should have the same +++ on ALL haswell processors , so for those of us hating on how our chips are not running like the engineering samples we all hoped for - this SHOULD rectify the problems and bring us into engineer sample territory 


W A R N I N G  :

I am about to update my bios and don't give a dessert rats anus about whether my motherboard bricks because I did NOT wait for years to upgrade from my faithful 920 to this . I want to see myself and all of us running at least 4.4-4.6 on our extravagant air cooling setups  but BE warned that messing it up may cause your board to go bye bye . 

I really hope mine doesnt go bye bye . IF it does Im just going to get another one and smash mine into itsy bity pieces as ASRock do NOT RMA bricked motherboards . They release buggy bios that brick them quite happily though . 

 

 

 

So far the Haswell overclocking run has been a disappointing one at best and I AM SAD 



Ill touch base within 24 hours for those of you who's interest I peaked . Wish me luck . 4.2ghz at 1.26V is not cool . I'm hoping the update will help me achieve the same at sub 1.2V the way those magical engineering samples do and should that be the case I hope the word spreads that its just a simple matter of updating your bios , or bricking your motherboard..

lol i had a laugh.

 

i dont think you have much to worry about if there's no physical damage to your board you should be covered under warranty!

 

flash away and good luck

 

i helped one user get a decent 4.6 oc but his first real hurdle was a bios update!

 

haswell is different, your now up against the ring bus when overclocking.

 

check out my guide, maybe it will help you!

Well dude, you made two very bad decisions if you want to overclock so badly.

1. Haswell (4670k/4770k) are terrible overclockers. 4.2GHz is about average for them. 

2. ASRock Motherboards are usually bad for extreme overclocking. And anything over the average (4.2 for Haswell) may as well be considered extreme. This is due to ASRock having only "ok" power delivery. I own the Extreme4 with a 3570k. I bricked my BIOS using the built-in utility to update it in the BIOS. 

Then I emailed ASRock and they sent me a new BIOS chip that was pre-flashed with the new BIOS. That was the only way I could get the BIOS to update. 

So yeah. Good luck. But you will not be getting much farther and should just be happy you got to 4.2GHz. It is Haswell on an ASRock board. Tis life.

Was that a full air cooler and fan on your ram?wtf

[Wats]

Is that a tower on your mosfets ???

 

NICE mod! I want to see some more shots of that.

 

 

 

Pretty sure its just a socketed ROM, they should send ya another if you ask.

[hehehehhehehehe]

ASrock is shit for overclocking don't buy their products. ASUS, MSI or even Gigabtype are better. And if you really want a high overclock on air cooling with haswell good luck y0 unless u get a golden chip ur done

Are you serious...?

[Ddm5]

Aren't the 2 fans on the on the left tower of the cpu cooler facing into each other? :L

Edit: Anyone that wants to know which CPU cooler it is: http://www.overclockers.co.uk/showproduct.php?prodid=HS-011-PL&groupid=701&catid=2330

[ahmed307731]

DDM 5 . Well Spotted ! Thanks , they are indeed facing the wrong way heheh . Temps were still awesome though this should help quite a bit !

Thumbs up to you

The cooler : Prolimatech Black Genessis .

Dual rad - one parallel to the motherboard over the ram with ram clearance not an issue blowing air through over the MB / ram

The other Rad dedicated to CPU

Got those High performance 2350 rpm corsairs - running at 1000 rpm . Silent as heck move good air . Cooling performance ain't all that but good enough for my target 4.2 Ghz easy .

Pokon thanks for the link I will review the guide shortly -

I successfully got the update on my second attempt and now guess what !

It booted into Windows with 4.2 Ghz after setting the vcore to 1.18V !! However the Vcore reading was 0.888 V ?! And it even managed to complete about 4 minutes stable on P95 before failing !

That's was awesome !!! I just got kicked out if the tech center to break for lunch , regardless of what most of you just said about Asrock being a crappy over locker - I have about 6 reviews that say differently.

HOWEVER that's not to say you are not wrong - I just managed to get a relatively cool few runs in P95 @ 1.18V running 4.2Ghz ! The update had a significant impact and the stream seems to run more fluid , shutdowns and startups run .

Going to review the guides referred by Pokon and see why it was reading 0.888v while under load ..

Only had an hour to tinker but looked promising even though I'm v inexperienced with these new Z87 bios OC tweak options .

This ring thing , you tubing some vid tutorials now hitting the rig again in an hour or so .

Appreciate the feedback people .

I will post a few more pics of the system just waiting for my sleeved vga extension cables and the evga pro sli bridge ... Cause I like shiny things .

I really hope I can get 4.6 Ghz :( so many forums and users with the same Asrock line have ...equal amounts have failed . Lets see what fate has in store for me.

Touch base with you all later

4.2GHz is about average for them.

 

Yeah.. ran into a brick wall with my 4670k at 4.4 GHz. Had to up VCore to 1.30, which resulted in Watt-peaks well above the TDP, and it still wasn't 100% stable. Next I *thought* I had found stability at 4.3 GHz with 1.24, then 1.25 Vcore. But even though the system seemed to run fine during various stress tests yesterday (1 hour Aida64, full benchruns on 3DMark, PC Mark and Performancetest + some gaming), it crashed on me today after just 30 mins of gaming. Reverted to 4.2 and 1.25 and now it *seems* stable once again. Temperatures were not an issue - my H60 didn't even seem to break a sweat at 4.4 GHz - but the CPU definitely doesn't seem like an OC-monster. Still: I can live with 4.2 as long as it's running stable.

My 4670K runs 4.6 @ 1.27 24/7. I'm not even sure if that's mine's limit either; I just stopped at 4.6 once it was stable. I think I may have got one of the better chips.

Wow.. sounds great! What kind of temps are you getting at that speed and how's your wattage looking? Are you exceeding the TDP with those settings under load?

Haven't had a chance to re attempt any overclocking .

What I will be doing though is delidding the CPU as my temp spreads are > 12 degrees highest to lowest core (4.2 Ghz stable around 1.2V)

Supposedly replacing Tim yields awesome results .

Ill post before and after temps then go back into my oc'ing .

I have a feeling that I should be able to get 4.4 , maybe even higher just need to figure out my mobo settings .

To be honest I'm happy with 4.0 straight up , it's more than enough for gaming with sli , coming from my 920 man this thing is smoking

I learnt that using prime 95 is not a good benchmarking tool thanks to an earlier post on this thread , so will be trying out the Intel Extreme Tuning Utility .

I will also be posting up pictures of the Asrock UEFI Bios - would appreciate some insight into what all you awesome chip owners have got setup so that us less fortunate may prosper

P.S.

I learnt to delid my processor on YouTube . Got a vice , electrical tape , block and hammer .++ new Tim

Has anyone tried this ?

Supposedly temps drop based on before after temps of + 20c AVERAGE reported .

Haswell is not the same as Ivy. The z87 chipset is one where even the cheapest mobo can support up to 4.8 ghz if the cpu and cooling are up for it. This is not because of the mobo but because of the built in voltage regulator on the cpu.

Lucky you.

[ahmed307731]

I traded my 4670k for a 4770k + small premium - its one of the best 4770ks out there - running 4.6 @ 1.25 - Aida 64 stable after 3 hours of stress testing .


NOW one of my gtx 780's (got 2 ) is running at 100% fan speed!!

Tried other drivers , older ones and same thing 

 

 

Tried using fan control on evga precision - it reads running at 40% idle but Aida reads it at 100% and Ive de synchronized both of them - the second one controls just fine but the first one doesnt budge although the software allows me to throttle it back and forth its stuck at 100% and loud!

any ideas?

Emailed EVGA and awaiting a response , will repost this under the correct forum subsection for gpu's but totally sucks. 


If anyone has any ideas as to why this might be happening please let me know ...
