    It's been suggested that 1.45V is the maximum safe 24-7 with a 6700K, so I'd imagine the same is with Kaby Lake. To be conservative, probably no more than 1.4 V.

    I suspect that delid would lead to further improvements in performance, perhaps 100-200 MHz and much cooler temperatures. There have been claims of more than 20-C delidded, which considering the history of delidding isn't improbable. Combined with delidding, most people could probably get 5 GHz at 1.4V, perhaps a few even going as 5.1 or 5.2 GHz.

    Thanks for the preview. Looking forward to the full review.


    CPU progress seems to have stalled. We are basically at 2600K speeds, only with Skylake IPC, more or less and faster DDR4 RAM. I guess the only other real improvement is DMI 3.0, which is valuable for an NVMe SSD.

    Hopefully this means that the Skylake X will OC as well as a 6700K. A 5960X could do 4.4 to 4.6 GHz at 24-7 voltages, which was pretty much the same as a 4770k. 4790K could do perhaps 250-300 MHz better on average.

    I ran my "bad" 7700K up to 1.45v, but I was informed that was highly inadvisable. Take that for what it is worth. But you are going to have some serious cooling issues there. I am thinking we should be looking at 1.38v at HIGH.

    Dammit, I see no transferable improvement in gaming (3! Fps in games that already run above 100 at best, oh wow), but seeing it can go up to 5 GHz and use 3866 GHz Ram still causes my e-peen to itch :D

    Am I the only one like this here?

    Actually it was like this with 6700k, which all early reviewers got to 4.7 or 4.8 at 1.35 or less, which wasn't that much widespread when it hit retail.

    May be time to finally upgrade my old i7 860. :eek:

    Even at 4.8 Ghz, a 7700k would be almost 2x the speed of my old system.

    Guess I'll wait and see if I can find a deal on a 7700k or a better deal on a 6700k

    I'd be willing to loan out my 2600k, Asus z68 Mobo and 16gb ram for such a test, but given the failing state of the Mobo, not sure how valid the results would be. Up to Kyle if it's worth the hassle...

    What would you guys want to see a basic IPC comparison with the testing suite? What does yours clock at?

    So do either the Kaby Lake procs or the Z270 chipset have Thunderbolt 3 / USB 3.1 integrated? I've heard mention that one of them does, but haven't seen anything today to support that.

    Maybe do it with VR games?

    I can almost guarantee that it will get you some extra clocks. But why not just turn off some cores too and get extra clocks? So I double up our work and test with AVX specific titles to show differences?

    I can clock down specific cores as well too to half clocks.

    To be perfectly honest, I think this is better left to the folks here in our forum and the LN2 guys that clock for clocks. :)

    I have always been of the mindset to show you what we could get in terms of clocks with full cores and features turned on.

    I'm game. Ship it over. If I kill it, it's on you though. :) Would likely just shoot for 4.5GHz to test at if it would be stable enough for overclocking benchmarks.

    I went through two bags of CPUs today and could not put my hands on a Sandy Bridge. :(

    I will PM you my shipping address.

    More than a few folks in this thread will likely very much like this tweet.

    Can we expect the same results on Z170 (memory speed and a conservative OC)? I'm currently running a 6700k which can't overclock a damn with memory at 3Ghz (less than XMP), would look at the 7700k if I could overclock AND run my memory at XMP.

    Doesn't seem worth it to jump over to Z270 based on the comparison charts I've seen.

    If you go for OC - then change mb as well. If not - there's no reason. My 6700k is also one of those potatoes that runs 4.5 at 1.32 and doesn't want to run 4.6 even at 1.35, but I don't want to go higher than this.

    So I have looked around, may have missed it, but when is the 7700k supposedly going to available for purchase?

    7700K at Amazon.

    7600K at Amazon.

    Why? Kyle said it is most likely the IMC that makes the difference and then demonstrated with the 6700k on a Z270 board.

    I'll wait to see how it goes on the Z170 first.

    Also, if it runs well, this is an easy drop in replacement for a Z170 system. Swapping a motherboard on the other hand, yeah, no thanks.

    That de-lid device shown in the video on that page is pretty nifty. I bet someone could sell them for like $20 each or put 3d printer instructions up.

    Edit: I couldn't find a price on the german tool used in the video, but this Rocket 88 version is $30.

    They also seem to have a relid kit. Why would anyone bother relidding? Can you do this much better than factory?

    That is pretty damn sweet. Lemme see if they will send one for review.

    Relidding with TIM replacement is probably the way to do to ensure not breaking the die. Admittedly, I would not really worry about it myself for personal usage, but I can see a bunch of folks that would want the insurance.

    So what's everyone thoughts on intel and the desktop cpus they put out? have we hit peak mainstream CPU? Perf increases from one gen to the next being 0 < 5% or so seems lackluster to say the least. What if anything can we look forward to with cannonlake(?) or whatever comes after kabylake?

    That is slick too bad Intel is so cheap I like how they put the thing in the oven to cure the glue or whatever.
    I would get one but have no need for it currently....

    So you are saying that in the UEFI that you cannot key in an integer higher than 40? Have you tired using the + key in that field?

    Set ASUS Multicore to Disabled. Got to Power Options in the OS and set it to High Power. CPU Ratio Sync All Cores. See if that nets you anything.

    I think they could hit better performance, but there is no competition at this time in the server market from a high performance perspective, and the money is in low power / mobile. So that's what they're focusing on.

    I think I tried out all kinds of combinations between auto and manual by now
    It's been like 2 hours :rolleyes:

    I also fiddled around with speed step, turbo yes and no

    Hell I can see the thing go down to a multi of 8 when nothing is happening when I choose a balanced power plan

    I click on high performance it goes up to roughly 4.2 ghz

    This feels like the override is actually not working

    Maybe it's a bit too early on the bios side yet

    yeah that's possible. 'cause technically it is working properly, just not OCing as well as you hoped. maybe future bios refinement will help that.

    It's just not OC'ing at all

    It's a K cpu, free multiplier and all
    Usually when you see an oc guide on a K cpu all they do is set the multiplier to what feels right
    And the start fiddling with the Voltages

    It's also running stable ;)
    Voltages go up and down link I want them to :ROFLMAO:

    That being said

    I found another user on the Asus RoG forum who seemed to have issues with the current bios and Kabylake as well

    Maybe it's just too early
    The NDA just lifted

    ah well I guess you have to wait and see or email asus. it is working correctly at stock specs.

    I would start by setting the UEFI back to OPTIMIZED DEFAULTS if you have been messing with that much stuff.

    On an ASUS board you should be able to set Core Mult, vCore, RAM speed, and not have the issues you are.

    Might flash the BIOS too in order to make sure all is good.

    Turn off Turbo and just set the multiplier to X?

    Not sure what to tell you brother. You should be able to scale the CPU clock with what I have told you here.

    ASUS BETA UEFI are safe to use. Don't sweat that at all.

    Are there any jumpers on that board for things like LN2 OCing? Might get out the manual and make sure that all the jumpers/switches are where they should be.
