    Yeah, The silicon lottery will rule:cool:
    Reasonable word (from the thread). About exactly same as what I said in previous post. Neither more nor less.

    Yep, they recommend x264 as a medium-heavy benchmark to test stability, and recommend an overnight test of that x264. If my CPU passes that test then great, but I'll still probably throw OCCT at it tomorrow, I need to satisfy my curiosity as to whether it's stable or not on it, haha! Plus, if it is stable on OCCT for 3 hrs that'll just make me feel like it's rock stable - see as that link says & as you're kind of alluding to here, we're getting into grey areas of what is stable & what is not, it's always a never ending debate between overclockers on the internet! I'd prefer my PC to be stable slightly beyond the most extreme real world usage I could see, which is why I'd prefer my overclocks to be OCCT stable, mind you x264 for hours stable is more usage than my real world, but I like to be sure! How do you test your 24/7 everyday usable overclocks?

    Ok, cool, I've finalised my new overclock now on my delidded CPU (6700K), it's 4.7Ghz on core & cache @1.376-1.4V fluctuating depending on load. I verified the overclock with x264 benchmark ran overnight, as well as 3 hours stable on OCCT, I've also done some gaming in Titanfall 2 & F1 2015 with no issues. Temperatures are really good I reckon, you can see in the pics below (Average Temperature column is applicable as I reset HWMonitor sensors before starting each test):

    x264 Overnight Stability Test
    x64 4.7Ghz stability test.jpg
    OCCT 3hr Stability Test
    OCCT 4.7Ghz (21.8degC room).jpg
    Titanfall 2 1hr
    4.7 Ghz 1hr Titanfall 2 gaming (22 degC room temp).jpg
    F1 2015 Benchmark Loop (Stormy Weather Setting: nearly 100% consistent CPU load)
    F1 2015 Stormy 4.7Ghz (22 degC room).jpg

    So, delidding gave me another 100Mhz of overclock, as well as lower temperatures. That additional 100Mhz overclock came at the expense of an extra 50mv, which actually happens to fit with 'the rule' that each +100Mhz requires 50mv, which is mentioned in this guide: http://www.overclock.net/t/1570313/skylake-overclocking-guide-with-statistics
    My CPU also seems to sit slap bang in the middle of the results in terms of "luck of the Silicon Lottery", which can be seen in that guide above that the median overclock on a 6700K is 4.7Ghz@1.38V - such mediocrity!

    Great that everything worked well.
    FYI. I have seen the newer OCCT v4.5.0 push harder than the older version you use. Take a look and download:vbthumbsup:

    Thanks for the congrats, pleased with the results of the delid & the slightly higher overclock. About the new OCCT, I really think I've pushed my new overclock hard enough, it's way beyond any of my normal workloads, so I don't think I'll compromise my successful overclock by running an even more stressful tester. Older OCCT program I'm using is still more stressful than Prime95 v26.6 in my experience - in terms of finding unstable overclocks quicker, so I'm fine with that. I know you yourself are not an advocate of using crazy extreme overclock testing programs/regimes.

    Cheers, do you have 6700K or 7700K or something else? Will be interesting to hear how you get on.

    I delidded my 6700k last week as I was seeing temps spike up into the 80s during gaming and prime95 would easily hit 95 after a few minutes at 1.35v using a cryorig h7.

    Now at 1.37v I see spike to the 60s during gaming and prime95 hit into the upper 70s and lower 80s using the same cooler. I used the RockItCool tool and thermal grizzly liquid metal. Totally worth it for me, was nerve racking but fun at the same time.
