Overclocking i7 6700K past 4.6Ghz?

Hello people,

I have managed to get my i7 6700K to 4.6ghz at a voltage of 1.395v. Not the greatest but any lower voltage makes it fail the RealBench test. With temps of 22ish idle and 73ish max load using a H115i.

I have tried 4.7ghz on that voltage but to no avail. Even going up .1v at a time all the way to 1.45v.

It may be that that's what my chip can do and that's that. Just to clarify, these are my settings with XMP on:

The settings on there are from an attempt at 4.7. No luck as stated above. What other possible settings may help in this circumstance?

If this is all my chip can do then fair enough. It's a lottery after all.

Any help greatly appreciated.

There's little user input required on Z170 really. Most if not all boards are capable and auto ruling should do just fine most of the time, perhaps with the exception of high memory overclocks where adjustments to IO and VCCSA will be required from the user. Either consider delidding, getting better cooling or make do.

Thanks for the reply.

Delidding I've not tried before and probably wouldn't risk it. Better cooling I presume is for allowing a higher voltage for the chance to add more speed?

I'll probably end up making do to be honest. 4.6Ghz is still pretty good on a 6700K.

I managed a 4.5Ghz OC on my 3770K, I was lucky with that chip. Not so much with this one I guess.
 
Better cooling may net you the extra leg room you are looking for. Skylake responds well to good low ambient cooling, as well as delidding. Then again it might not, but your options are limited. I'd be happy with 4.6.
 
From what I've read Skylake does not gain as much from delidding as previous CPUs do.

Not to be rude, but H115i is not great. Top air will cool just a well, maybe better .. especially if running high airflow fans at similar noise levels to CLCs. CLCs have two big problems; low quality pumps that move less coolant at maximum speed than a component H2O pump moves at an idle, and low quality radiators with high density fin counts that require very high volume of airflow from high powered fans to push air though them at speeds needed to remove the heat. Their pumps use about the same amount of power a high-performance fan uses. The entire CLC system weights about the same as just a component radiator does. ;)
 
Hi All

Am fairly new to Overclocking but after following various guides I have by 6700K up to 4.8 and stable

Just want to check that these temps and voltages are ok?

Any advice critical or otherwise welcome :)

I'm no expert but looks good mate. What case and cooling do you have?

I've got a luxe with three 140 fans and a H115i. My 6700k is 4.7ghz at 1.345v. I've run aida64,cinebench, xtu and real bench for stability. Hits 69 degrees on performance mode or early 70's on balanced.

Haven't tried 4.8 yet. Might give it a go

looks okay so far to me.
what are your stats (mainly core temps and cpu package power) if you run prime95 small ftt ?

I have a Luxe with an H110GTX

70 was the max CPU temps I have had

Stable at 4.8 but blue screened not long after I tried 4.9, is it safe to give it a bit more Vcore and try and push it further?

Yes, am new to xtu though, so why so low?

Yeah that's odd mate. Think I got around 1250 stock?

After you finish the benchmark it allows you to compare with others. Have a butchers of that and see what the comparisons are

Just read that xtu is also very ram dependant. What ram you running?
I've got 16gb corsair vengeance 3000mhz

I have 16GB Corsair Dominator so decent Ram

Ill have a further play and report back
