i7 6700k silicon lottery

[Lord Nicoll]

So it's alomost time for me to buy my new CPU, which if you read the title you should know is the i7 6700k, but while I have a very good idea of what a good chip is (very very rare to go beyond 4.95GHz with insane voltage) and what a bad chip is (1.375+ volts for 4.7GHz) it seems the vast majority of these chips do 4.7-4.9GHz with between 1.3-1.35 volts with some lower and some higher, but that I've stuggled to find or work out is what percentage, and thus what chance, I have of betting a dud or a gem? Anyone have any idea? My initial numbers put it around the 80% of getting an acceptable chip with about 10% for  it being a gem and another 10% being a dud, but that looks too well rounded and perfect so I'm wondering what other peoples experiences are.

That's simply not something that you are going to find

Yeah, I prefer large samples but so far, looking at the amount I found, it's barely 30 results. But the i7 6700k is a pretty consistent compared to some, Intel already rung a lot of the performance out of it.

I managed a max of 4.8ghz without crazy volts, but did not keep it there as the non soldered ihs can't take the heat and at 4.8 or 4.9 ull be in the 85 to 100c

yeah I miss those Indium soldered CPU IHS's

thus why i run 6850k

My max is 4.5 @1.325v Anymore on the core grants crashing.

I don't use the consumer LGA 2011-3's if my work load can benefit from extra cores I use dual xeon boards, I have a few from LGA 1366 to LGA 1567 and some first gen old LGA 2011-3.

Lol most people getting 4.7-4.9 with under 1.35v has gotta be a joke. If you get that consider yourself lucky not average.

The most accurate numbers are probably from SiliconLottery as it's their job to bin chips like these. They say that 95% of chips can reach 4.6Ghz at 1.392V, 61% of chips can get 4.7Ghz at 1.408V, 19% can get 4.8Ghz at 1.424V, and 3% of chips can get 4.9Ghz at 1.44V.

I reckon those numbers might be cases of "omg my chip is awesome I'ma tell everyone" Whereas poorer chips go unannounced.
