    Passed the ROG RealBench stress test for one hour with these settings:

    • 50x CPU Multiplier
    • 1.408V CPU VCORE (Or less)
    Test equipment:

    • Motherboard: Asus Maximus VIII Hero
    • Memory: 16GB 2400MHz 15-15-15-35
    • Graphics: Nvidia GTX 750 Ti
    • Cooler: Corsair H105 AIO
    • Thermal Paste: Arctic MX-4
    • Ambient temperature: 22°C

    additional info
    • 7700Ks are running about 5-7C warmer than 6700Ks on average at the same voltage.
    • Delidding is making a huge impact on that last 100MHz.

    That vcore seems kinda high, and RealBench isn't that heavy of a stress test. Meh.

    You get a binned 5Ghz 7700K for virtually the same price or less than a 7700k (+ tax) from amazon or newegg.

    I like the idea of getting something delidded for me, but yeah, that vcore is a bit nutso.

    A lot of them hit 5 for less volts. You're literally paying them for nothing.

    There's a bit of insurance in not taking the risk of damaging it yourself, I'll give you that.

    For the price they charge to relid, you can buy a rockit delidder with the relidding tool for 40 and get some CLU. Then you can not only do it yourself, but place ad in craigslist and make money doing it for others. A syringe of CLU will do like 10 chips, probably more.

    I'll do a lot of things that others won't... but roofs and delidding processors I will not do. :)

    Although, if I was to delid it I'd go all the way and direct die cool. Make the hassle worth it.

    To be fair, its not hard with a razor and it is stupid simple with a rockit delidder.

    I would not run naked, it's not worth the hassle and risk. With relidding, worse case ya don't glue or let the IHS cure properly, temps are bad. With naked, you screw up, you chip/crack the die and you are hosed. And with relidding temps are already greatly improved, 20c or higher. That's good enough no need to get greedy.

    IMO this is not a "deal", maybe if these were binned to 5.2ghz+. All the reviewers are saying 70-80% of retail chips can do 5ghz, unless thats just shrill hype I don't see the point buying these.

    Also these were binned 5ghz with mem at 2400, might need slightly more voltage/more heat for same clocks with faster RAM (who would use 2400mhz mem with a 5ghz 7700k? they should have tested with 3200 at the least).

    Call me old fashioned but finding the OC of your own chip is half the fun anyway.

    But for the price your charging on Craig's list, a guy browsing Craig's List can buy a rockit delidder with the relidding tool for 40 and get some CLU. Then he can not only do it himself, but place an ad in craigslist and make money doing it for others. A syringe of CLU will do like 10 chips, probably more.

    So you would actually be the one ripping off people if you did it yourself.

    I don't really see the point of something like this. It seems like just like marketing to some via emotional appeal.

    On a practical level the performance difference between 5ghz and 4.8ghz is marginal, the amount of people with workloads in which such a difference will actually matter is almost no one?

    If you're just doing it just for the sake of doing it as an enthusiast out of interest then it seems like you'd want to be doing all the steps yourself. It'd be like buying a boutique PC build and saying you did so just because you're into building PCs.

    That voltage is fine as long as the cpu is well cooled. I just started running my 5820K at 1.38v to achieve 4.6Ghz. I did a ton .... a shit ton of research. The voltage is fine. A lot of kids think that you can smoke your cpu and all this other crap but the truth is, there is extremely low proof of this. I've even seen where Intel engineers have commented on this in the past when asked and they generally say, no, you're okay with that voltage even over long periods of use.

    High heat is what kills cpu's.

    Look at it another way. Use your CPU, hotrod it to hell and back. If it breaks, get a new one. $300 is not a great deal of money. Changes are very good in your favor this won't happen. That you won't break your CPU.

    This terrible advice. $300 is a lot for many and volts will indeed kill your CPU. Usually quicker than heat which is more of a long term problem so long as you aren't running at 80C+ constantly with the CPU.

    That voltage is completely fine for long term use..Intel's 22nm process is extremely robust..I have been running my personal 3770K @ 5.026Ghz since the day I got it..It has been de-lidded and I am running an XSPC Raystorm block direct die mounted with CLU...I have run both 290s loaded with Furmark and Prime95 loading all the cpu cores for 48 hours and it has never given me any trouble..I actually beat on this rig, as it has spent 98% of life with GPUs and the CPU loaded 100%, which produces the most heat possible...IF I can pass a ~4 year stress test without killing a CPU @ 1.45V, then running a gaming rig with that voltage is going to be fine...

    And before I get the but that's only one sample, I have built ~38 gaming rigs over the last 4 years, each OC'd to the near limit without a single failure..

    I am not sure I would pay $379 for a 5Ghz Kabby, but if there is still headroom left then it might be worth it..I personally have NEVER lost the silicon lottery going back to my AMD K6-2 days..I had a Celery 300A@550, P3 533 @ 668 (that is a 167mhz FSB in the days of ~100Mhz and 133Mhz), dual P3 733s@ 1Ghz (rip Abit BP6 ), and the first Athlon T-bird 1Ghz to break 1.35Ghz 24/7 stable here and on Anandtech.

    Based on my past success, I am willing to roll the dice on a random sample..I am tempted to get a 7700K since my MSI Z77 MPower MB's first PCI-E slot is getting a bit flaky, but I am waiting to see if AMD hits the home run I am expecting with Ryzen..

    Sorry dude not going to trust random guy on the internet about something like that. Not when I've watched plenty other people over the years IRL and on various forums kill their chips or lose the ability to overclock due to over volting less than that.

    The 7700k is on a completely different process than those chips. Might as well talk about how a P4 ran at 1.7 volts so it's ok.

    The generally accepted 24/7 safe zone for this process is under 1.4v. It can be pushed to 1.45v but over that and you're into the red zone.

    My 6700K does 4.8 @ 1.32V on air. Aside from ambient temps listed, what were the temps during testing?

    Doesn't look like much of deal from over here.

    Is there a big difference from the i7 6700 to the one in OP?

    1.5v was the supposed 'limit' for Sandybridge; ran my 2600K @5.2ghz with 1.52v for over 2 years. No problems.
    1.4v is the laughable 'limit' thrown about regarding Haswell with its FIVR, yet been running my 4790K @ 5ghz with 1.51v-1.52v for over a year now.

    I watercool with an oversized radiator, and from my experience it's heat that kills CPUs.


    On topic, I'd say now it's more important than ever to go for a binned chip, as it seems modern chips have a hardwall limit that you just can't cross regardless of voltage. That's what Kyle found with their weaker 7700Ks. It's also what we're seeing with GPU clocks (Nvidia at least) lately.

    Nowadays a chip either can or it can't.

    My 3.4 GHz 3770 has been rock solid at 4.6 GHz for nearly five years and that's on the stock cooler and stock voltage.

    But like others, I'm hoping Ryzen is a worth it and I'll have an excuse to upgrade!

    Just like there are plenty of people who will pay extra for a factory hot rod instead of building it themselves, there are plenty of people who want a fast computer for bragging rights among their friends even if all they do is watch youtube. I know one of these folks, and used to build him a new system every couple of years. His son and friends are the same way. So there's a pretty big market for stuff like this....filled with fools. Then again, seems the country's at least half filled with fools lately.......so maybe that's where they got their idea to market this. A fool and his money......

    Based on SiliconLottery's own stats, 62% of 7700K's are making 5Ghz with their cooling / motherboard setup. The odds are good anyway.

    It seems that by spending $380, you're probably eliminating the possibility of getting a 5.1Ghz+ chip (listed at 24% odds on their site, with 4% for 5.2Ghz)

    I'd just buy, test, and sell CPUs until I got what I wanted...
