Intel Core i7 7th Gen - Core i7-7700K Kaby Lake Quad-Core 4.2 GHz LGA 1151 91W BX80677I77700K Desktop Processor

Pros: Hero IX has it OC'd to 5 with a tower air cooler. And it's running cool, too; rarely hear a peep out of the fan.
Super fast. It typed this review before I even touched the keyboard.

Cons: Pins being on the board gives me the heebeejeebies. But as thin as they are, I don't think I'd be comfortable with them on the processor, either. I suppose that's just agiven as the tech gets smaller and faster. I'm afraid I might have to be a licensed neurosurgeon when I get around to replacing this one 5 years down the road.

Overall Review: None

Pros: -It's an i7! No more 100% cpu usage where my i5 6600k did.
-It's possibly the fastest quad core i7 on the planet depending on how far you can push it.
-It is pretty much the exact same price as an older 6700k, which was released back in 2015.
-No need to upgrade to a z270. motherboard assuming you have a z170 with a proper BIOS version.
-I got my computer to boot and initiate a stress test at 5.0Ghz with 1.41v but it was way too hot so I stopped it in less than a minute. Definitely wanting to go back to it when I upgrade my cooler.

Cons: -This i7 is extremely hot compared to my old 6600k, even at much lower voltages.
-Core #0 and Core #1 are consistently running 5-10c hotter depending on load than #3 and #4. Something I never saw with my 6600k
-The stock/default BIOS settings are terrible, DO NOT use them (at least on my motherboard) Reason being: it was pushing the vcore over 1.40v just to run its 4.5ghz turbo boost which is totally unacceptable.
-Maybe it's just me, or maybe a lot of people don't use very good stress testing software, either way, the overclocking on my chip is mediocre at best, from what I can tell. (more info below, but it's mostly from heat)
-There's no i7 sticker that came with it, my 6600k never had an i5 sticker so I wasn't expecting it, but it's sure a nice bonus when you are buying an enthusiast processor.
-I honestly don't know whether to be impressed or dissapointed that I upgraded from a 6600k. I wasn't expecting much, but the heat/overclocking potential is harder to maintain than my 6600k was 100% for sure.

Overall Review: Running this processor on the Gigabyte G1 Gaming Z170x Gaming 7 motherboard with a 212 Evo and Arctic Silver 5(exactly the same products as my 6600k ran off of)
I use "OCCT 4.4.2" for stress testing because in my personal opinion it's far more effective than the other options for achieving a truly stable overclock (it crashes unstable settings in literally 2 seconds, and detects core failures in less than 60 seconds when your getting close to stable, sometimes). I see a lot of AIDA64 tests and I've had my 6600k pass that, but then bluescreen in game. I don't consider AIDA64 to mean anything, but that's just my opinion.

Right now it has been stress testing at 4.5Ghz (core and uncore) for about 1 hour at 1.25v (1.236-1.248) and it seems to be stable. 1.24v is a bluescreen in 2 seconds. My temperatures at this voltage are acceptable, and SLIGHTLY (5c at best) lower than my 1.36v 4.7Ghz 6600k was. Obviously this isn't an overclock but I really don't want to push the vcore any higher until I get a better cooling setup, although I might try to get 4.6Ghz later just to say I have it overclocked. I had it running stable at 4.8Ghz core and 4.5Ghz uncore with 1.35v earlier. The temperatures were consistently exceeding 90c on core #0 and #1 even though the 212 runs at 100% once it hits 68c.To give you an idea of why I'm not happy, I ran my 6600k at 4.7Ghz core and uncore at 1.36v stable for all of 2016. My temperatures would not exceed 80c using the same stress test, and would literally never even hit 68c for my 212 to run at 100% in use outside of stress testing. Obviously you aren't garunteed good overclocking results, but the temperature difference is way too high compared to what I'm used to, I feel like this is lazyness/carelessness from Intel since there is no competition and they just want to maximize profits.

I hope I don't get downvoted unreasonably for my feedback on this chip. Everything I have said is true, and these hotter core issues are also being noticed by other people, including the motherboard overvoltage at stock (1.40v +) Everyone should really do some research on this chip if they are thinking about buying it and be sure to get as good of cooler as you can since you will need it. This processor NEEDS to be manually adjusted if you want it to be running within normal voltages
