What is the highest you guys can overclock and get into windows with your 4770k?


At what voltage?

Mine is 1.37-1.38V needed.

I've almost got 32M superPI cracked at 4.9Ghz, it freezes at around loop 20, so close.

First day I am testing my system as my Asus Maximus VI Hero got here yesterday.

Thus far I have managed to get into windows 8 with 5Ghz with 1.3v, but halfway through a 32M SuperPi it crashed. Needs more voltage I guess, but I am not willing to go more than 1.3 just yet.

Managed to get 6m 43s in SuperPi with 4.9Ghz @ 1.25v with 1866MHz Corsair RAM which seems decent.

Now I will try and see how stable I can get it at 4.8Ghz with 1.25v. Though as long as it can do 4.5/6Ghz under 1.3v fully stable without deliding, I will be happy for the time being.

Seems like you've got yourself nice chip there!

Yeah, after all the reading I have been doing, the chip has so far turned out to be better than I was expecting.

But I won't get too happy until I can get it running some apps that will really put it to a test.

Will post with screen shots and more spec details soon :)
 
What are you guys actually using to stress, as atm i going for 4.8 and whilst i can get into windows with 1.28v, stressing is a completely different matter!!. Im @ 1.36v now trying to stress with OCCT but doesn't last more than 20 seconds b4 blue screening, but with ADIA64 im currently at 1.32v and has been stressing for 15mins now!!, should i even bother with OCCT??
 
tried with ibt standard? idk how well you can cope with heat but I do 5 runs on maximum stress in ibt on ivy 4.8ghz-79c

for haswell id start at standard stress in ibt then move up one notch
 
Nah never used ibt, i had always used OCCT in the past, but not sure if its complete over kill. The intel guy on the NewEgg Overclocking video was using ADIA64, and was said to be the best program to use for stress testing Haswell as it stress all the new commands that haswell uses as well
 
I have done superpi, hyperpi, cinebench and now aida64 stability test on 4.8GHz@ 1.275v

The first 3 was easy. But after 5 mins of aida64 it crashed. I upped voltage to 1.280, also set min and max cpu cache ratio to 47 and am running aida right now. No throttling yet, but from max 89c it is now max 96c.

Ok, now at 6 mins 26 CPU it throttled and I stopped it.

By the way, everything else is on auto and left unchanged. Not touched llc or anything like that.

Dropped voltage down to 1.26v and running aida again. Max 95c now so far 15 mins in no throttle yet. So it seems to safely run 4.8ghz deliding will be needed. But could be done with some tweaking also I think without deliding. I have only spent a few hours testing yet.

By the way I am cooling it with a Kraken x60 push pull.
 
So far for my stresstesting I've mostly been using AIDA64 and Intel® Extreme Tuning Utility (Intel® XTU) for artificial tests, and Handbrake for a more real life test which also really strains the system. (Handbrake has crashed my system one or two times after AIDA64 didn't crash :mad:) ... I might do some more testing with OCCT and IBT as well once I'm mostly happy with my settings.
