4770k OC and intel processor replacement

[beginner99]

As if Haswell CPUs are manufactured in two different kinds of fabs, one that is producing chips on 22nm process transistors finetuned for desktop and capable of hitting 4.8 with sub 1.2V and 2nd one that is optimized for low power, but as a sad sideeffect requires massive voltage for 4.3+ Ghz setting.

But then intel would be retarded to sell any "K" version chips from the worse factory if the issue really is that simple (different factories).

This is also why you pay for an extra chip with the tuning plan.

How do you figure you're paying for an extra chip with the warranty? True, the plan does cost you $20-$35 for each cpu, but I doubt Intel's cost per cpu, at least with the upper level cpus, is $25 or $35 each.

But that's not how much they're actually getting for each replacement CPU they send out. Only a small fraction of the people who buy the plan will actually need to make use of it- its the standard insurance business model.

They will never reenter the chain. They get destroyed instead. This is also why you pay for an extra chip with the tuning plan. No sales lost, no extra cost added, just another chip produced and one destroyed.

Don't see why they would destroy chips that pass re-validation. $25-35 for an extra chip and you think they won't reuse the good ones? Why not change their rating to a lower clocked non-K and sell them to specific market OEMs, i.e. developing markets? Just can't see Intel not doing something like that. After all they can tell which chips have actually been damaged.

Not quiet since you do no need to purchase it before hand.

I haven't seen a retroactive life insurance policy, but if you find one let me know :thumbsup:

You just described my processor to a T, literally.

*idle temperature is 30~35 @stock and 35~38 @4.3ghz

somewhat stable @4.3ghz with not really a useable voltage setting, around 1.4v~ manual voltage.

Temperature is high NOT because my voltage settings are high.

So after 2 full days of testing I concluded that the realistic setting would be @4.2ghz 1.3v + with 90c+ degrees under load.......

4Ghz was stable at 1.12v. But 4.2Ghz was unstable at 1.25, mostly stable at 1.28, but even at 1.3v which seemed stable I see an event log error saying the processor caught a self-check parity error.

At this temp Linpack runs will eventuallly plateau the temps at 80c. Which is absurd for a triple 140mm radiator, because my previous 920 was cooler at more volts on a triple 120mm rad.

I wish you luck with your replacement, but these bad chips are more common than most websites would lead people to believe. I sincerely regret even buying a "K" part now for multiple reasons, as VT-d would give me better performance than any OC I could attain at this point. Intel knew exactly what they were doing when they disabled turbo-multipler overclocking with Haswell chips, as I would've recommended that option instead of a "K" part to everyone. At this point I won't even recommend them at all, I sincerely regret buying into Haswell.

Regarding your AVX issue, OCCT's AVX-Linpack testing worked fine on my chip. Wasn't even aware Linx was still updated.

All of the suggested fraud in this thread blows me away. Intel or any other company for that matter do NOT make any promise of any overclock results, only that they will not lock them. Sending a CPU back because it doesnt do as well as you want makes return processes harder for the rest of us and cause the prices to go up as well.

Be an adult, take what you get and be glad that you got anything above stock.

In raw cost it is that. Assuming all the R&D etc is payed by the first chip and the second one is simply a replacement.

They already destroy chips with non working cores.

Also you can never garantee something that has been out of your control. That why we call things for refurb and not brand new.

Some people get it worse, my Titan Overclocks by 5% and rattles at idle at P8 so I need to keep it at P0 state.

 

[Rvenger]

This frightens me because my CPU hits 72c at stock speeds out of the box. My board is a dud so it won't change frequency at all.

 

[Galatian]

Maybe I overlooked it, but did you use offset-overclocking? I found that to be very simple and efficient with my i5-3570K @ 4,5 GHz.
Maybe that's the way the Haswells should be over clocked? Just sayin

 

[guskline]

I'll hold on to my 3770k at 4.4Ghz 🙂

 

[cytg111]

yea, gonna wait it out for a tad longer .. lets see what happens next ... if anything.

 

[Face2Face]

Sounds like the first 3570K I had. I couldn't get it past 4.2 either. Be careful about telling some people on this forum if you are going to exchange it. They get all churchy on you...

De-lid it, put in some LMP and drop the temps. Might get some OC headroom out of it that way.

Anyone suggesting fraudulent action should be infracted at the very least.

If the chip won't pass everything under the sun at stock return it, if it's just a crap OC issue, woe is you.

You can still purchase the protection plan and find out how long too much voltage takes to degrade your chip to the point where it won't run stock anymore.

 

[NFarnzy]

I have a 4770k and I have it at 4.4ghz 1.27v.. It is probably an avg chip but
I am happy with it.

As they should, its fraud. You are returning something under the guise that it is defective when in fact you just didnt win the luck of the draw and now you are mad about it.

Think of overclocking as a bonus, not a right. You are promised only the specified xxxxmhz stated in documentation/on box, anything in excess is just gravy. If it doesnt meet that stock value then by all means complain all you want, but this is just the entitlement mentality of our community shining bright.
