Recently purchased a new Haswell-based CPU only to run into an overclocking nightmare? Looking for some tips to get a bit more out of your chip? After pushing the limits for several weeks and ending up with more than a few dead chips, we've come up with a guide focused on 24/7 overclocking with Haswell!

Nice guide Dave definitely proved useful for a couple rigs I have built in the last week or so.
 
nice guide

nice guide,could have been more useful for me if you would have used a gigabyte motherboard.
meanwhile i need 1.25V for 4.2 GHZ,
and 1.4V for 4.5.
 
I'll give it a read this weekend! I tried the 46 x 100 @ 1.25 and I can boot fully into windows with about 10% load anything more goes bsod.
 
Looks great so far with lots of good info, read through page 4 thus far. Thanks Dave :toast:
 
Very nice guide. Due to the technical nature of the subject, I imagine it was difficult to dumb it down a bit for people like me, whom have never OC'ed memory and/or were confused by the new Haswell.

Nicely done.
 
Not with blue team myself, but that was a good read. Well done :)
 
EPIC! Gonna go read it now! Thanks for the efforts Dave! :toast:
 
Thanks Dave for taking the time to write this guide:toast:
Look forward to reviewing it soon!!!
 
that did make it very easy to understand everything about the new chips dude, well done :D
 
This is exactly what I was looking for! Just picked up a Haswell rig to mess around with. I know how much time goes into doing an article like this and I very much appreciate it. I'll probably be reading this through a couple times at least!

Thanks for the thorough walk-through and enjoy this nice weekend weather Dave!
 
Great guide dave, as i discover more and more guides and information about hardware and overclocking you always seem to keep bringing me back to my roots with your in depth guides and wisdom about everything overclocking and helping to understand what exactly we're doing. keep up the great work :)
 
Excellent guide to haswell, its architecture, and your experience overclocking. I felt it to be more of a cpu review with some overclocking versus the title, but a great resource for all who read it! I hope to see this type of article with future CPUs for sure!

Thanks! :)
 
Thanks dave, even though I don't own a hasswell rig its still helpfull for me to grasp a better understanding of overclocking. . My hat goes of to you my friend. Great write up.
 
Dave, it's very interesting to see the advanced overclocking features Intel has put into Haswell which you've explained well here. It's then massively frustrating to see that they're all crap overclockers as reported in all the various reviews and articles around the web.

The chip you used for this article was running at 4.6GHz, which I take is the best overclock you could get out of it with complete stability? Well, that's yawn-worthy for the old Sandy Bridges as you know and even on my rig with initially a Zalman flower cooler I was able to briefly run the 2700K stably at 5.5GHz with the fan running flat out and the CPU had more to give. I'd bet that on water this chip could do 5.5GHz 24/7 without any problems.

Such a shame Intel are now tuning their chips for mobile applications and not the likes of us PC enthusiasts. With overclocking limitations like this, I just don't get why Intel designed all these enthusiast features into the chip?
 
Some chips clock fine my 4770k purchased from newegg can run 4.6 all day had it as high as 4.8 but heat due to TIM under the IHS rears its head. I usually get crappy clockers to so its just luck of the draw.
 
Great job!

Thanks for the great write up. I was thinking of getting an Haswell rig to play with since I may have a buyer for my Ivy rig. You said it was the luck of the draw in terms of Haswell. I was wondering what kind of OC did you get out of the bad chips? 4ghz? 4.2ghz? I can run my 3570k 1.2v @ 4.4ghz. If the worse chips only hit 4ghz, I probably won't take this gamble. I'll also probably be running only an H60 + ~$150 board :p
 
Ive never overclocked a CPU. This guide makes it much easier than I expected. Thanks!

You should stay ivy then.
 
Excellent article Dave! Someone give this man a prize goddamnit! :rockout:

It's all about the power consumption, baby. ;)

Also about increasing efficiency/clock cycle, no? Eg: Sandy needs 5Ghz to equal Ivy @ 4.6/4.7 & Has @ 4.4/4.5, small perf bumps but still there... Please, correct me if i'm wrong :o
 
Thanks for another great article. I ordered the 4670K and "Hero". Not sure about the RAM .. the Vengeance Pro isn't available yet.
 
Awesome stuff. It will definitely come in handy if I ever get to fiddle around with haswell.

Or more hardware to play with.
