Just changed my system to a an i7 4770k with an Asus IV Hero board (Came from i5 2500k on Asus V Gene)..

I was able to clock my I5 to 4.7 with absolutely no issues whatsoever, can I get this i7 past 4.2 !? can I heck !! .. Its BSODing, freezing in Bios .. only way to get it back stable is 4.2 at 1.2v .. what a mare !

Ive tried 4.4 at 1.25, 1.28, 1.3 all not even getting into windows .. so much so it corrupted it all and I had to do a restore before I put all my photos on which are now all lost !? grr

Any suggestions, can I change my CPU under warranty ?
 
no you can't change it because it doesn't overclock very well. haswell's are known for being rubbish at overclocking but it seems like you've got a pretty bad one.
 
Haswell overclocking is inconsistent, rather than straight out bad.

You can DSR it, but.... It's a bit of a kick in the teeth to the retailer.
 
Send it back. It's a K series so you paid for the overclocking and if the overclocking is crap then send it back.

Intel took a premium off of you for that so if you're not satisfied with it back it and get another one. I would.
 
you can only return it under DSR. if you're out of that period, then no as the chip is not faulty and OCing levels is not guaranteed.
 
Haswell OC is not just "raise vcore" -> "????" -> "Profit".

It takes some skill at least. Try reading the "templates" in:

http://www.overclock.net/t/1401976/the-gigabyte-z87-haswell-overclocking-oc-guide

Change the other settings as well. Play with the voltages within the safe limits set in the thread. You might not need as much Vcore to stabilize it, but you might need some Vring voltage instead. I know this is for gigabyte, just google for asus thingy as well.

I had a hard time getting my last 100mhz no matter what vcore I set. Then i changed some other settings and LLC -> boom, stable OC.

I can't believe a haswell wouldnt stabilise under 4.3ghz with a safe voltage.

No, do not DSR it. It ain't fair to the retailer.
 
I think it is harsh on the retailer to DSR a haswell CPU because it won't overclock very well. Take a look at 8-Pack's systems, the guy is testing maybe 100+ cpu's to hand pick them for his systems. Its the luck of the draw unfortunately, looks like you just got a bad cpu for OC'ing.
 
DSR = Distance Selling Regulations.
You say picked it up - if it was an in-shop purchase you're stuck with it really. Try to ebay it and get another 2nd hand one in, hope its a better clocker? :S
 
If it corrupted your data good chance its raising something else along with the CPU overclock - RAM, PCI(-e) buses or SATA, etc. which might be the cause of the instability before the CPU itself.
 
4.7 was pretty easy with the 2500k, I mean, mine clocks stable at 4.6 on auto settings, and 4.7 only took a very slight voltage bump.

Getting it stable past 5ghz was much more of a challenge, and then getting it to boot past 5.5 (not stable but for 1M runs) took even more effort.

How much did you have to do to get your 2500k stable at 4.7?

I know Haswell can be a poor clocker, but are you sure that a: You have tried hard enough and b: As Rroff says, are you sure this is 100% CPU hardware and not related to something else?
 
Firstly i agree with the posters who are telling him to use DSR Intel should drop the K prefix and the premium if overclocking is so bad on Haswell or sell binned parts.

4.2 is pathetic really to be stuck on so what you need to do is look at temps volts and clock speed when you get one.You need to find the wall at which the chip refuses to boot.

For example postman delivers a 4770k i install it, set bios to 1.3v set to x45 multi and attempt to boot.You can get a general consensus of how the chip fairs just by looking for the multiplier wall and briefly running a benchmark like prime or a stressful game like crysis 3 or bf4 beta.


If it just refuses to boot you know you have a stinker!
 
4.2ghz on haswell = 4.8ghz on sandy roughly,and as above haswell needs more tweaking/refining than sandy does
 
Read up on overclocking Haswell cpu's a bit more. You need to do a few things more than just whack the voltage up.

My 4770k will only go to 4.2 with just a voltage increase but after tweaking other settings I have it stable at 4.6Ghz.

Thanks..

I'm using the same hardware as in my previous build, I'm guessing that because both boards were asus rog then the components should be ok ?

At 4.2 it's stable so if it was some other component would it not be unstable here too ??

Cheers

This^^ we should a the very least expect a respectable overclock, we've paid for it.
