Overclocking Intel's latest Sandybridge processors properly requires a completely fresh approach.… A re-thinking of everything you have come to know and understand.
Just the voltages alone are enough to make even the most experienced overclocker stop dead in their tracks and check everything twice before continuing. In almost every situation, when it comes to electronics, too much electricity manifests itself as an increase in operating temperature. Zapping 1.6 volts through previous Intel processors could have resulted in an immediate trip to your local store to replace the chip. With Intel's Core i5 2600k, it barely went above 80 degrees in our most severe testing. Taking no chances, KitGuru went with the huge Austrian sandwich that is the Noctua NH D14, but even a cooler costing half as much is likely to yield some pretty stunning results.
For continuous use, we would recommend 4.8Ghz with 1.47v – that set up is easy to achieve and unlikely (but not impossible!) to create a problem. Naturally, whenever you touch the clocks/voltages on a system, you have kissed your warranty goodbye and that's no one's fault by your own – so be warned!
When all is said and done, this overclocking article had a very simple question in mind when it was started…
“Can Intel's 2600k beat the awesome Core i7 980 Extreme Edition?“
Compared to the fastest desktop processor in the world, at stock speed, the 2600k is almost 30% behind. Using KitGuru's building skills, we cranked the voltage to 1.6, rolled the clocks up to a steady 5.1Ghz and watched it breeze past the Extreme Edition by more than 10%.
This is a simply stunning result and we'll say it again, in the simplest terms possible, “At just £250, the overclocked 2600k processor can out-render the £800 i7 980 Extreme Edition at 3.33GHz, straight from the box”.
If the Core i7 980 Extreme Edition makes the mistake of running at stock speed when taking on the 2600k processor, then it's in for a serious surprise. KitGuru's overclocked 2600k happily takes the Core i7 980x outside for a swift beating, not only in hardcore rendering tasks like Cinebench 11.5, but also in the SiSoft Sandra tests – including the Arithmetic, Multimedia and Cryptography sections. In doing so, it barely goes above 80 degrees. Amazing.
KitGuru says: Intel's latest architecture stands alone. Price, performance and all round flexibility mean that the second generation Core processors are going to be every enthusiast's first choice for a long time to come. The bar has been raised, the challenge made and its now down to the competition to think hard and see if any kind of intelligent response can be found.
Final ‘horror thought'? What is the Extreme Edition version of the second generation Core processor going to look like?
5.1ghz is a pretty crazy overclock. that voltage as you say might kill the CPU long term, but its very cool to see
thats crazy man !
4.8ghz seems much safer long term, but thanks for going the extra mile to show us what is possible.
5.1ghz on air? dear lord, I need to get one of these processors and motherboards.
Not much to say to this, apart from ‘lol’. seems you got them further than others ive read today. still 4.8ghz looks safer to me. especially after buying it.
heh, this is class. Those processors seem to love the juice, I know a few people on the XS forums run their older core cpus just under 1.6v so id say you would still get pretty long life out of it if you wanted to play hard.
well done, very good for an intel board and extremely impressive for new architecture
That noctua NH D14 really never fails to get me hard. its better than some watercooling kits.
Well I had almost bought a 1100T from AMd, and now I really don’t know what to do these are so damn good and the price points are excellent. the 1100T costs around the same as the 2600K and it wont really go past 4.3ghz.
Well done. great work.
Heck, even im impressed and im so bored of tech now I fall asleep with most new releases. This setup is wicked Zardon and im really happy you have helped us try and get the same oc’s, although im not sure im brave enough to risk 5.1ghz. For the purposes of this article though, damn nice to see.
Noctua NH D14 has just been ordered and ill be looking at one of the asrock boards and perhaps the 2600K in a few weeks.
Awesome. When the guys with LN2 get these, I can only imagine the OC.
Fantastic work on these,. has really helped to push the platform to me.
what a mega overclock, love it.
Now, this is what im talking about 5ghz+ on air. who doesnt want that. if they dont’ they need to move sites.
are you sure the price is right? AMD would be well overpriced if this was accurate. 170 for the 2500 and 250 ish for the 2600 ?
Well I dont know about anyone else, but this is fucking impressive. I know you guys had a lot of good ocing with the 875k but most people didnt; this however seems to be killer.
reading the sites online , it seems 4.8ghz is the speed they are getting them too. Trust Zardon to crank it more 😉
5.1ghz ? fuck me.
I love my Noctua NH D14,. always love the fact KG seem to use them for these all the time. nothign else to go for.
Oops.I jizzed in my pants
Hey I have a similar set up with the Asus P8P67 deluxe. I bought the MB CPU and RAM as a bundle pre-OCed to 4.6ghz. I found it was very unstable though and BSOD on prime95 only took 20min. I checked the BIOS and they had the CPU volts at 1.33v with seemed a bit low, so I increased the volts till prime ran stable for 5hours. It’s now at 1.38v but maxed 80c core temp, which seems kinda high.
I’m really annoyed as I bought the bundle to prevent having to do the OC myself, I have requested an rma from the company in question so hope that I will get this sorted. Was just wondering if there is anything more I could try first. Gonna try removing the Heatsink and remounting it. Also shall see how my other settings compare to you guys.
My first OC so I’m a novice.
