How easy to OC a 4770k?

[HEIS3NB3RG]

Buying a prebuilt system and the 3.5ghz 4770k is £120 cheaper compared to the 4.3ghz.

I have never done anything like it before, is it relatively straight forward? I know 4.3ghz is a modest OC for a 4770k so surely a beginner can manage it?

I'm slightly worried I am going to fry the system, is this possible?

Thanks

It would be possible but, be warned, OCUK apply a binning process to the CPUs they put in the pre-builts, meaning they put the good clockers in the most overclocked systems, and the poor clockers in the non-overclocked systems (which is a very sensible way of doing things, of course) - That's why you pay the extra for the big overclocks.

I see, looks like the ones without overclocks will be pretty useless overclocking wise then! haha

Why not build the system yourself from scratch? it will take 4 hours at most

I got to 4.2ghz by only changing the multiplier to 42x and the core voltage to a very modest 1.20V.

Imo if your going to pay a premium for an overclock might as well go for something 4.6+ ghz as that takes an effort to achieve

thats the main reason imo not to buy ur chip from oc

I think they would only do that with system builds.

I got retail 3570k chip from here at £150 and it clocks great 4.7ghz 24/7 and then 5ghz in benchmarks on air.

Personally I think you should have ago at building it your self everything is pretty straight forward and there is plenty of tutorials out there to help you along your way and read through before you start.

I know I really should but I don't trust myself with £1000 worth of gear!

You are fine as long as you buy a retail CPU, they are sealed before leaving the factory. If I remember correctly I had to break an Intel seal sticker to get into my retail 3570K.

It is not as bad as you think. Remember most of us have self built, and the forum is here if you encounter any problems.

The chips that go into pre oc'd systems/bundles are purchased separately from the retail or oem chips that you buy individually. Hence if you buy a chip by itself be it retail or oem, your taking the chance on wether it clocks or not. You get this same chance buying from any shop. The ones in the bundles etc are bought from known batches that guarantee oc's and are for systems and bundles only. Iirc someone on here posted a while back that there are different guys in the shop responsible for bringing in the different chips.

If i recall correctly one of the OC.UK staff have said that they dont open and bench retail CPUs. So if you buy retail instead of OEM you should be getting an untouched chip.

When i bought my 4770k and my sabertooth z87 the board took the cpu to 4,0ghz on its own with no input from me at all. Right now im running 4,5 stable at 1.28v. Which isnt super great but also could be a lot worse to. I achieved this knowing abselutely nothing about haswell overclocking and its actually pretty simple most of the way. The difficult part comes when you want to squeze that last 100-200mhz out of it and you have to mess with all the sub systems. This is where i get off the bus an settle for what i have

Just remember haswell IS HOT! My h100i can keep the peaks from stresstesting around 81-84 celsius after i changed the fans on it to something better. I sooo want to delid this bad boy but cant afford it right now if i screw up. Also the extra performance isnt needed with a single 780(even oced to 1350core).
