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?
 
I was also told an interesting nugget today that "all" the reviewers that did agree to Intel's embargo and took Intel's samples are getting 5.0GHz to 5.1GHz, which is something to think about.
This is why I read the [H].

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.
 
It would be interesting if uesing the same high end gpu at settings we would game at if you even notice that much of a difference gameplay wise. I ditched my 3930k set up for a 6850 when the mb started going out. Gaming at 4k felt about the same but some productivity programs got a nice bump.
I think it is sad that we have come so litle in the last 5 years just think how bad it would be if gpus advanced so litle.
Maybe do it with VR games?
 
I don't know where you stop doing it. Perhaps an investigation on our behalf: Is it work it to downclock AVX to achieve a higher overclock in various applications and games? Or is AVX too important of a feature to downclock for that? I don't have the answer.
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.

It's been at the lazy auto-oc setting of 4.3ghz for most of its life. Been underwater for that time as well. IIRC I thought I saw 4.6 or so when I tried to see what I could get out of it, but it has many years since I really cared.

Basic IPC would work, especially if would be some of the same stuff we would be seeing later with Ryzen.

We all know the new stuff should be faster, but with so much incremental and this old stuff keeping around as long as it has, would be interesting to see how strong the case to upgrade for the sake of upgrading and not replacing failing components really is now.
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.

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.

Dunno, not there yet, but on the radar.

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?

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.
 
IMO there is no overclocking discussion without delidding discussion. the thermal interface is too important https://forums.anandtech.com/thread...ies-overclocks-inside-now-with-delid.2493250/
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?

Relid to sell this time with better tim

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....
 
I have installed my 7600k just now

But for some reason I can't get above its 4 Ghz boost speed

On an asus maximus VIII formula


You wouldn't have an Asus board for testing that you used, well an z170 that is?

It's the most recent bios with kabylake support
Also everything detected correctly after I installed it

I just can't get past x40 as a multiplier

CPU-Z even shows me the max multiplier I set in the bios
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.
 
No it does not
Power plan was set to high

I also changed it to 99% on the cpu power and back up to 100%
Cores where actually synced
And just now disabled the asus Multicore enhancement

Stays at normal boost ratios

mmm
Maybe bios still needs some time

maybe set thing manually instead of auto
 
maybe set thing manually instead of auto
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.
 
It's fine

Just wanted to see if I had overlooked something
But frankly there are just not many options to play around with


Thx Kyle

Gonna see in a week or 2 I'm sure how big an issue it is (widespread or something with the current bios version)
There seem other users having trouble with the version I'm using
Which is the most current

Except a beta bios
Not sure I want to mess with that :cautious:
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.
 
OK

Thanks to you're comment
I did try

And it works just like it's supposed to

So yeah there's just not an official bios out for FULL kaby lake support

Thx Kyle
Glad to get to the bottom of it. :)
