Going from 5.2 Ghz to 5.3 Ghz costs you another 50% on the 8600k and 8700k. o_0
Still a giant waste of money for a marginal gain of few hundred MHz and running over 1.4 volts on it is going to be super hard to cool. I guess if your a benchmark junkie I can see it, but other then that I question why.
really an impressive improvement over kaby lake when you take into account that they added two cores 5.2 ghz 1.4v kaby was top tier pretty much

58% are good for 5.1GHz...not bad.

Very interesting data.
Much more useful than the legions of people lying about their OCs on the internets .
These are 100% useful data, since they are confident enough in their testing to warranty their work.
I don't really feel like those overclock results are all that impressive when you consider the AVX offset. It feels like people not wanting to admit that they can't hit 5ghz and settling for 5ghz in anything not remotely demanding and 4.8ghz in everything else. I can get into windows just fine with 5ghz on my i7 8700K but the second I fire up prime95 and smallffts.. good luck. 90C+ and instability within seconds or Cinebench @ 5ghz. I have to crank the voltage to 1.4V+ and LLC 7 and I've delidded with a Kraken X62. If the AVX offset was limited to affecting synthetic benchmarks thats one thing, but my clocks were being throttled by the AVX offset in games I was not expecting, like PUBG/Heroes of the storm, etc. Which made me feel like it would be be better to just go for a lower overclock overall and not use the AVX offset at all, so you know where your clocks/performance were going to be.
Don't get me wrong, I'm happy with the cpu overall, I just think that the media/reviewers went a little crazy and set the expectations sky high for what overclocks people should expect, similar to my experience with haswell.
...even there, given how much work each AVX instruction is actually doing (replacing 4 or 8 traditional FP ops), it's still quite amazing to run at 4.8 MHz. The throughput is kinda nuts.
People that feel like using an AVX offset and "only" running AVX at 4.8 are crazy in my opinion.

So the coupon is giving me errors in the mobile app. The coupon works on m.newegg BUT I can't log into my account.
The gods do not favor me.
This is punishment for buying a cheap tablet.
so what mobo to get for overclock? Was thinking Asrock extreme4, k6 or taichi? However I like MSI...
I'm deliberating between the Taichi and Gigabyte K7. The Extreme 4 is supposed to be very good, but the on board audio is pretty low end.
Great ... So it looks like there is a silicon lottery for asrock K6... how do I win it? is there anything on the package telling me what I should be getting?Maybe this will help.
Yes, some games are legitimately triggering AVX offset, because they are really using some AVX instructions. This has been shown by a few guys testing over at overclockers.co.uk.
BUT...this is spot on.
