I don't know if this is any good but I got hold of the following:

Asus Z270 Tuf mk 2
i5 7600K
16 gb Kingston ram

I certainly wouldn't consider myself an overclocker by any means, but I've been playing around with "intel extreme tuning utility" and in 4 steps I'm up to 4.7ghz without touching the Vcore which is running at stock of 1.13v, thats the highest I saw as it tends to fluctuate a bit when benching. I've used the utility benching tool but I certainly don't know how stressful it is in relation to say "prime95" 'frinstance.
temps didn't even hit 60c, staying around the 56c-57c mark.
I get a ctd when I set 4.8ghz but I haven't gone anywhere near the voltages yet so maybe I can get it higher.:)
 
XTU is fine for stability testing, used it for testing my 6600K initially, and what passed the XTU test also passed Realbench test and was perfectly stable for my use.

Enjoy overclocking, let us know how you get on! I would just stick 1.3v through it as a starter and start upping the multi. Keep an eye on temps but if you're using the H55 as your sig says then you should be fine. I would just keep upping voltage until you get around 80c under load then see what frequency you can get stable, looking around 5ghz looks like a good number to go for!
 
Right, just hit 5ghz real easy but its early days yet. I just set the cpu voltage in the bios to 1.225v, went into windows and opened the intel extreme utility, banged the multi up to 50 and ran the benchmark 3 times at 5ghz no problems.
I haven't tried anything more stressful or demanding but I'm surprised how easy it was to get to 5ghz. Temps were also low as I never saw higher than 62c.
 
Well I set 4.6ghz and I just ran prime 95 for about an hour and the temps really started to rise, actually saw 78c on one of the cores, Vcore was reading 1.3v ish, so I decided to stop the test at that point. I don't think the cpu workload will ever reach that level and I'm more concerned with gaming and general usage stability anyway.
What tests are there that are more "real world" workload simulations? I reckon I'd like to see if this cpu is stable at 5ghz maybe even a bit higher if possible, although for my purposes, 4.5-4.6 is probably where I'd keep it.:)
 
Yep another vote to stay away from Prime95 here, it takes the testing way overboard than that is necessary. I've read elsewhere that Prime hasn't been safe to use since around the Broadwell days.

Got the asus realbench....so, do I use the stress test (which I don't really want to as it its fairly intensive so the blurb says) or just the benchmark option?

Edit: Ran the Stress test for 15 mins at 4.7ghz and 4.8ghz at stock volts (the board overvolts the Vcore accordingly as far as I can make out, it sat throughout both test runs at 1.344v, also the same for 4.5ghz)
Temps ran up to an average of 73c-77c with the very occasional spike of 80c-81c. Seems I could do with an improved cooling solution if I want to lower those temps a bit. I'll try 4.9 and 5.0 later this week and post back here.:)

Okies, I had a little play around with overclocking this morning and got to 5ghz with no effort at all. I did a 15 minute stress test using realbench 2.43 (I know it should be longer but time is against me here.
All bios settings were at stock except for cpu fan profile which I set to "turbo" which means the fan speed starts to increase at a lower temp, in this case 55c), I then set the cpu multi to 50 using the intel extreme tweaker in windows. The highest temp I saw was 82c which showed for about 2-3 seconds, then dropped down to a lowest of 70c and I reckon the average temp would be around 75c. Vcore stayed at a max of 1.36v.

I'm quite impressed with meself here as I'm not really an overclocker and this cpu took no real effort to get to 5ghz and I think with a bit of tweaking it'll go higher still, it might even go a bit higher without any further tweaking.:)
 
Good results man. Temps are OK but I wouldn't want them any higher really, so just keep voltage as is and see what CPU multi you can manage with an hour or so of Asus Realbench stress test. I've never needed to test any longer than that :) 5ghz is a good result though well done!
 
Just had another run at 5.1ghz for 15 mins, passed stress test with ease, max Vcore was 1.360v, temps were still averaging around high 70s but with momentary spike up to 83c. I also set the cpu fan in the bios to continuous max speed. I reckon it could 5.2ghz on stock at least but I'm hitting the max cooling ability, after all I'm only using a Corsair H55 with single 120mm fan.
Still impressed with meself though:)
 
Now up to 5.2ghz, totally stock settings except for max cpu fan speed set to max. Temps were roughly the same as before but thats as far as I'm prepared to go without better cooling.
 
5.2ghz is awesome, the more I hear about kabylake the more I want one, even though I know the gains will be marginal :o

I would still go higher though, its not like you're putting more volts through it and temps are still OK :p
