I use MSI so it is different than asus. I could oc an non k i5 by about 400mhz. It may not work for you but it is worth a try.
Okay thanks I'll upload a video and link it here as well as the other guy's video with the ivy bridge and asus. I'll have to render the video first - so it will be smaller - and I'll upload it in some minutes.

Sounds good mate. I'm sure you can squeeze some more out of it

Other guy who could do this with XMP and asus mobo.

My video: trying the same way he did. I also enabled some kind of boost for non-k processors but seems like it's not working (sorry I've recorded it with my s2 and for some reason nowadays it can't really focus on things fast enough):

Okay, in this pic from your vid I put 2 boxes

It looked like you selected the top box, what happens when you select the second box?


Edit
Then further in is seems like you are trying what I am saying. I will have to research some more

I searched around but have found nothing. Are you running the latest BIOS?

No, it's the original BIOS which the mobo came with.

Maybe I found out why I can't overclock my i7, this is interesting:
Intel Prevents Overclocking of non-K Haswell Processors, and Strips Virtualization and TSX Features From K Parts | PC Perspective

Seems like intel totally locked non-K haswell so people can't even earn that +400-500mhz? I noticed you have Ivy Bridge i5 (never mind that's a k i5) and the video that I linked shows an Ivy Bridge processor. The few other sites which talk about this, always show an Ivy Bridge processor.
And I've talked on Youtube with someone who has haswell i7 4770 and can't overclock with an MSI/Gigabyte Mobo too - I think it's an MSI but I'm not sure now. He should choose from a list of preset multipliers up to 45x or 46x or so but he could only set the 39x max multiplier so it didn't work for him with haswell.

I don't get why intel did this with the non-k i7: it should have got the 4.0ghz base clock (and turbo 4.4ghz) because you can't overclock it, and people will overclock devils canyon anyway so it would reach higher clock speed than the stock non-k i7. Especially since devils canyon has trouble going over 4.8ghz as far as I know so at least overclockers would have bigger room for overclock from a lower base clock.
If I could OC my i7 freely, I'd definetely set 1 core to 4.6-4.7ghz because of the old or poorly written programs which still use 1 or 2 threads like some music encoders.

Yes, if you wanted to overclock you should have bought a K processor which has unlocked multiplier. Non-K processors are not intended for overclocking. Intel never promised anyone any overclocking capabilities except on the K processors.

Even if you did have a K version the likelihood you could hit 4.6 - 4.7 is not that good. You might get there with a turbo overclock for 1 or 2 cores, but that is also unlikely IMO.

Virtualization had priority over overclocking. And yes I want only 1 core to go to as high as 4.8ghz or around that because of slow 1-threaded programs which would benefit from it greatly. I would be good with 4 cores even at 4.2-4.0ghz.
I was just curious if after like 3-4 years when this processor is outdated how far can I overclock this non-k chip - knowing Intel wouldn't give newer processors more than 5-15% speed improvement low-overclock would be ideal with the same voltage. But it's not that important.
