Unlucky Haswell CPU?

I wouldn't if bought Haswell to begin with... It's a dog of a clocker.

4.2Ghz is a decent clock as many people have got worse.

I hope you RMA/DSR this and you get a even worse chip.

Some people

Yeah, thanks, I appreciate your help getting more from this CPU, but as you clearly cba to assist me in getting the most from this, and preferred to post wishing me bad luck, I'll not take offence...

You lost the right to help when you came outwith this selfish comment..

Think I may RMA it. General consensus seems to be 4.2 at 1.3v is a complete dog. I agree based on the weight of evidence out there. Shame

People like you that do that ruin it for others.

you could buy the Intel Performance Tuning Protection Plan for Core i5 4670K CPU.

Was looking at that just now

There was no help, get it?, have you actually read my thread?. How about, you do what's just been done on another site, give me some good input as why I cant post past 4.2?. I'll assume as you did not post, that you don't have a clue, or prefer to post some arsey comment once you smell blood?

I thought putting in for an RMA was a tad cheeky, but don't post on here with your holier than thou attitude. Its an overclocking forum, what do you expect?, satisfaction that I have the 'dog end' of a CPU?.

Whatever pal.

Why? There's nothing wrong with the chip. It just doesn't overclock stably as far as he wants it too.

As mentioned before no-one guarantees how far an overclock will go. If they did then the manufacturers would just overclock it themselves and sell it as the stock chip.

No, you don't have to be happy about it but accept that you rolled the dice and lost, take it gracefully on the chin like most others would do.

Not, like you have, have a tantrum that even my 3yr old niece would be embarrassed by. :rolleyes:

Quite agree with Space Monkey. Just because it's a "k" series doesn't guarantee a certain overclock. 4.2ghz is a 800mhz overclock so it's fulfilled it's overclocking capability. You have just lucked out with this particular cpu.

Yes, no doubt I have lucked out, but my first post was asking for help, as I'm not an OC guru, and am finding a lot of mixed info about over-clocking this CPU, I was just after some guidance from the people I trust most on these things, Ocers.

whats the 50% voltage drop on the graphics for?

Hmm apologies missed your question. Not sure what you mean drop in voltage for the GFX?

I doubt you can RMA it, it's not faulty.

If you're within time you can return it under the Distance Selling Regulations or 14 Day Satisfaction Guarantee.

You're not allowed to have more than one forum account. Perhaps you should ask the Mods to close one before both get closed.

Yeah I was not aware of that, but my temp account has been permbanned, so its been actioned for me

because if he was to go full water cool loop he could push it abit further and not worry.

I find it curious that your instability appears whilst you're loading windows before you start putting the CPU under load. Are you using a negative voltage offset or any other settings that might reduce voltage under low load?

Not as far as I know.
I had reset Optimized Defaults before I tried any profile changes. I can make it into Windows with x44, but its totally unstable, so did not want to keep pumping more into the CPU core voltage. If I understand it, I can up the VRIN to 2.0 which I'm going to try today, as well as setting load line calibration to medium and check the voltage/temps with IETU.

Originally I was going to go for something like the H80i, but as this upgrade was unplanned, I had to skimp on cooling, for the time being anyway. I'm more confused by my temps, which are low, so I've got some headroom, I even slacked out with paste, using the stuff that came with the cooler, as my Arctic Silver 5 looked like it had gone off. I'm just don't think increasing CPU core is fixing stability, its something else I'm not aware of, but I'm doing some more reading :eek:

My 4770K is only happy up to 4.2GHz too, also on a Gigabyte GAZ87X-D3H but in my case it's only on 1.18v Vcore, so runs cool with my Noctua NH-U14S. When I push past 4.2GHz and I've tried 4.3GHz, 4.4GHz and 4.5GHz and Vcore up to 1.28V it boots ok but will fail P95 or eventually just blue screen (0x124 error) while doing something else, not even necessarily pushing it hard. I did just try increasing the speeds and leaving the voltages on auto, which went well over 1.3V but the results were the same. I do a lot of 3D rendering, which involves the CPU being used hard for hours on end, so I decided to stick with my lowly but cool and very stable overclock at 4.2GHz @1.18v. Max core temps are between 58C and 62C after a couple of hours or more of rendering and gaming rarely breaks 50C - I can live with that.

Will try some more tweaks, not 'unhappy' with 4..2, but coming from a Phenom 965 @3.9, 300hz, this Haswell feels a little thin as an upgrade. I'm sure it will reach further, just some trial and error

Bam · 28 Apr 2014 at 00:02

Would the reason in temperature difference be mainly down to TIM application?
Ideally I'd like them all to be at 69c under load at x43 :confused:

Mads1 · 28 Apr 2014 at 02:32

what cooler are you using by the way. Just look on utube and on OCuk overclock guide there are loads of tutorial's out there that may be able to help, but on haswell i wouldnt go above 1.275v well i know i wouldnt.

andy_taximan · 28 Apr 2014 at 04:52

Its probably nothing much but the Proposed Processor Graphics Voltage drops from 1.000V to 0.500V ? im new at this so was wondering

My i7 4770K is at 4.2 atm hope to get it higher but hey ho ,
There is 1 way of making sure you get a better overclocker and that is buy a cpu/mobo combo that has been overclocked before you buy it! but weres the fun in that ? ! lol

Yeah, lots of info on Haswell OCing, but for the old in the tooth like me, used to upping FSB and whacking some voltage into a chip with a case full of 120mm fans, VRIN and Load Line Callibration, and their relationships is a bit complex, if you're not wanting to instantly fry your chip :cool:

Got it at 4.3 semi-stable (15ms IETU) at 1.3 76c which isn't bad, will try to stabalize tonight. That was using LLC set to High.
