Today I upgraded from my trusty 2500k to a 4770k and am having troubles OCing it.
I'm just working with VCore and CPU ratio at the moment and am having trouble getting it stable at 4.3Ghz with 1.34v :(
Have I just got a dud?
 
My 4670K is only properly stable at 4.2 Ghz at 1.25v whereas I could easily get 5Ghz with not much more voltage on the 2500k. But due to the increase in performance clock for clock, the difference between the two is small.

Haswell is known to be bad at overclocking and you often get people running at 4.6 np. But for the fast majority of people, the max you'll get is around 4.4.

If I was you, I wouldnt dump that much voltage into the chip, see where you can go at 1.2v and 1.3v as they seem to be the sweet spots.
 
It seems stable at 4.3Ghz with 1.35v, but as you say that's quite a lot of voltage.

What's the max recommended temps for these chips?
This chip's temps are scary for me - I'm used to seeing under 60C :o
 
They are very hot runners, mine will hit 94c in seconds of loading up under p95. Vcore of 1.265 @4.5ghz.
 
I just tend to go with 8 Packs reccomendation of not using p95, all it proves is that your system can run p95.
 
Its luck. Do some googling and you'll see that its common for a 4770k to not overclock well/live up to expectations. Mine is not great and needs 1.32v for 4.4, 1.37 for 4.6 and 1.45 for 4.7. I wouldn't go further than 1.35v on air but that's up to you and what temps you get, I'd be happy with anything less than mid-low 80's.

If you have the desire to go further, you can delid which will net you more headroom on voltages and is not as hard/risky as some make out. In fact its quite fun :D

BTW, worry more about temps than voltage. You can run 24/7 over 1.5 if you have the right cooling.

These threads make me want to send back my unopend 4770k and MB and go down the the Ivy-E route.

Fire it up and see what it's like first. Bad choice of words to start with i know. But you might have been lucky to get a decent one.:D
 
They all differ. Mine easily hits 4.5ghz, but after that I have to give it a silly amount of voltage. Prime will get it to 85C, but nothing I use it for gets it above 65C.
 
I will just waiting on some more stuff to come dont really want to take my current rig apart just was alway on the edge between this and the Ivy-E but prefered the giga oc board and obiviously the price was on the haswell build side as well :p
 
Tbf, it's only in synthetic tests such as p95/ibt that they hit very high temps. In normal use such as games my 4770k runs at 65c max, pretty much on a par with other overclocked intels of late that ive owned.

Yes l had the same dilemma Hades sorry Haswell or X79, depending what specs you wanted for both. There is very little price wise between them -

My two Spec's Z87/X79 -
CPU -
4820k - £259.99 inc VAT.
4770K - £269.99 inc VAT.

MOBO -
Asus X79 DELUXE Intel X79 (Socket 2011) - £279.95 inc VAT.
Asus Z87 MAXIMUS VI FORMULA Intel Z87 - £249.95 inc VAT.

Ram -
TeamGroup Vulcan GOLD 8GB (2x4GB) DDR3 PC3-17100C11 2133MHz Dual Channel Kit £69.95 inc VAT x2 - £139.90 for X79.
TeamGroup Vulcan GOLD 16GB (2x8GB) DDR3 PC3-17100C11 2133MHz Dual Channel Kit - £129.95 inc VAT Z87.


X79 Bulid Total = £679.84
Z87 Bulid Total = £649.89

Only £29.95 between them again it all depends on what spec you want.

Hope you enjoy your new build, by the way l went X79 Route.

I went 4770k more for the aesthetics of wanting an orange build, the price is a factor of course but I have a fairly good budget for this build/project so am happy to send this back and go for the Ivy-E will give oit some thought this weekend and twist the wifes are when I tell her I am going to spend even more. As I think I will go 4930 probably a waste on me but i do enjoy tinkering with some benching. :D
