overclocking for the first time

[Wink]

and.................. i get a max of 4.3 with 1.25 volts.... off my 4770k

 

man, colour me disappointed... sigh.....

[Guest]

I never had a chance to Oc processors, but i'm just going to guess it's bad, try to push it to 4.6

[Rashy]

PUSH IT TO 5!!! Also make sure you dont have stock cooler, stocks are bad.... evil...

thats about average tbh. should have bought a 3770k or 2600k if you wanted lots of ghz.

[LogicalDrm]

If your cooler can take it, I'd go for 1.3V or even 1.35V. Anyway thats pretty normal OC for haswell.

[Wink]

is it? i was using linus tech tips vid to judge, and according to that vid, my oc is in the crappy region. haha

 

im trying other video tutorials on what to push, but i think its pretty safe to say i didnt win the silicone lottery.,....

4.2-4.4ghz is average for haswell. reviewers normally get better ones.

oh, i didnt know that. that is good to know, kinda.... 

 

haha that did cheer me up in a way, cause that means that reviewers are effectively the tech world's porno stars, giving us unrealistic expectations of our expected performance....

lol. 

[harrynowl]

It makes me happy thought because it means my Sandy Bridge is still about the same speed as the average Haswell chip

[ProKoN]

@Wink like others have mentioned your results are fairly average. Look through the Haswell Database and you will see. These are real results from real people.

Average, not horrible at all at that voltage. The initial reviews are BS as is any review that has a ES chip in the CPU-Z. ES= Engineering Sample=highest possible binning and perhaps even solder under the lid. We might see those overclocks on Devil's Canyon as average, but not on current Haswell.

 

4.3 is fast. The chip is NOT a 3.9 on turbo on stock on all cores (that is only 1/2 core applications), so this is not just a 400 mhz overclock. I just lowered mine to 4.3 for the summer at 1.15V (I have all my windows open) and I am missing nothing from 4.5.

 

1.25v you prob want something like a dual tower Noctua or something similar. 1.3v? You might get 4.4 on a dual rad water cooler. Even 1.25v is too much for my evo 212. 

 

Not all Haswell's hit 4.5 and not all AMD's hit close to 5ghz. People selling you that they do are full of it or have limited experience on the platforms and might have just got lucky.

^ See the overclock guarantees on these stupidly expensive prebuilts? 4.0 is there under the I5/I7 K now as a minimum OC. That is on water. I imagine Origin doesn't go over 1.3v so 4.7 is about the best they have seen at that voltage and that would prob be on triple rad cooling. If you get a chip better then that? Go out and buy a lottery ticket the same day.

[The_Strict_Nein]

You see, this is why you need to invest in a real processor. I can put 1.7V through my Q6700 and it'll get part ways into windows before over-heating.

 

Honestly though, you can go up to 1.3V with Haswell. Depending on how good your cooling is, you can try and squeeze and extra couple hundred MHz out of it

[Faa]

Sure about it?

My cpu's stock speed is 3.2 or 3.3GHz cant remember exactly and it just boosts to an extra 100MHz in prime95 but but when I change the memory speed to 1600MHz or enable XMP the clock speed in prime95 is all the time 3.8GHz. Some boards use this agressive turbo and some don't as we see here: http://nl.hardware.info/reviews/4577/48/37-haswell-moederborden-vergelijkingstest-28x-z87-6x-h87-en-3x-b85-benchmarks-cinebench-115

Same thing to my older 2600K and friends their 3570k's as well because they all have asus boards. Asrock doesnt seem to be having this agressive turbo.

i managed to get 4.6 at 1.3v, but it wasnt stable. so ill drop it down a couple notches. I am using a H100i cooler. and it is winter now, so i'll need to make a summer profile too cause the stress test temps im getting are around 80 degs

 

Thanks for your guide, i read through it and understood what i have to do, so i will do another round of tests and see what my stable OC is.

 

 

 

Other than that, i hear what you guys are saying @deathjester and @jumper, i was on a spree of watching overclocking guides and techie vids, so i guess i was excited beyond realistic expectations. haha at least i got it at a bargain (by aussie standards) @ 300AUD. hopefully i will have some better news on my GPU.

4770k and non k. 1-2 cores is 3.9, 3 cores is 3.8, 4 is 3.7.

 

Turbo is based on cores used. An I5 K is 3.6 on 4 cores. So when you are "only getting" 4.3 on a I5? You are getting a 700 mhz OC on a 4 core game/application and it is actually not too shabby.

 

Here is a chart for the Intel I5's/I7's minus 2011 chips.

4770k:

base/idle: 3.5GHz

1core: 3.9GHz

2core: 3.8GHz

3core: 3.7GHz

4core: 3.6GHz

Whenever you enable xmp and if the motherboard supports the agressive turbo you get for 4 cores load 3.9GHz. Can show you a screenshot with the default settings prime95 cpu just boosting to 3.3GHz (from 3.2GHz) with all cores loaded and at 1333MHz and when I change the memory speed to 1600 or enable xmp I get 3.8GHz in prime95, just save me this effort cba doing this

Disappointed about 4.3Ghz, when some others have only been able to get 4Ghz out of theirs.

Consider yourself lucky, not unlucky

Jester is right

x39

x38

x37

 

 

This is the turbo frequency specification for a 4770K. XMP does not effect turbo. motherboard vendors may have more aggressive turbo values but that is not relevant. whats relevant is intel spec.

 

cpu is at 100% load xmp enabled

 

 

[Faa]

Jester is right

Which is what I've been saying, with every extra core being used 100MHz drops off.

Quickly loaded the default settings:

[nj4ck]

lol, my 4670k needs 1.33V for 4.3 GHz and you're complaining about 1.25.  :lol:  :lol:  :lol:

[ProKoN]

@Faa

 

did you seriously just compare a sandy-e part vs haswell

 

 

 

you need to get yourself a haswell chip my friend. you cleary lack in depth knowledge of haswell, sorry.

 

your recommendations as per haswell are generally far from accurate. adopt and master the platform before you start making suggestions.

Sorry but you're just flatout wrong.

"In the Cinebench benchmark, which purely tests CPU performance, the scores are very similar except for those board with a less aggressive 4-core Turbo."

Taken from: http://uk.hardware.info/reviews/4587/48/37-haswell-motherboard-group-test-28x-z87-6x-h87-and-3x-b85-benchmarks-cinebench-115

"The two MSI boards without the agressive 4-core Turbo that scored lower in Cinebench also score well here."

http://uk.hardware.info/reviews/4587/52/37-haswell-motherboard-group-test-28x-z87-6x-h87-and-3x-b85-energy-consumption-cinebench-115-max

Look at the gap in the scores between the asrock z87 fatality and all others, a 0.5 score in C11.5 can only be achieved with a higher cpu clock.

man, colour me disappointed... sigh.....

shouldn't be disappointed. I can't get past 4.2GHz on mine even with my h110, i learned to be happy with it

[Wink]

@deguziiii @nj4ck @SkilledRebuilds: Hi guys, thanks for sharing (and chiding), i truly thought i got a OCing dud according to the standards set by reviewers, but like the others before you pointed out, it seems like these tech reviewers (aka Porn stars) gave me an unrealistic view of what is normal.  not trying to get pity or complain, i was just overly excited, so the fall to reality was harder. OCing is something i JUST started, I wanted to try it out, im having fun trying to find a stable OC, so i am far from being unhappy with my chip and the rest of the goodies. 

 

 

That being said, @ProKoN i am getting up to 4.6 on 1.35v using your guide (Thanks btw) but it starts to throttle when i go into stress testing. I then lowered volt by 0.01 decrements but still throttling, this happened until i got to a point where it wouldnt POST.

I repeated the process while lowering CPU multiplier to 45 and 44 and still i would get cpu throttling from overheating.

 

is it my cooling solution at this point or is it that my chip cannot handle the OC?

 

my cooling solution is h100i on top intake, creating positive pressure system to limit dust buildup, but i know this mmight not be the most efficient cooling set up.
