I've been meaning to, just money hasn't worked out at the time the past year or two...

DDR4-3200 is working now with 7700K...

 

I drove there and had a place to stay for the 5 days I stayed. So only gas and food and drink while I was walking around. Kept trying to buy stuff, but they do not sell anything since they are all pretty much all manufacturers.

Yep. I had an idea it would work far better than the 6700K, that's for sure.
Nice!

 

I don't know if I have any friends still around there, unfortunately, which balloons cost. But I may try for next year (just have to book the hotel before they start raising the rates when booking starts for the show)...

Don't stay on the strip will keep cost down. Not sure where you would be flying in from though?

 

Do you handle Visa stuff ? XD

 

Most likely from Denver. Otherwise it would be a nice southwestern road trip!

Nice! After a bit more tinkering you should get a new geekbench score in... Speaking of which, I now know where I confused the time for closing on that, they state a different date in the rules than the counter for it...

I have friends that specialize in immigration, but one is in Kansas city area and most of the others are in the Virginia/DC area...

Yes, he's taking Visa and Mastercard, no problem...
Nope, no need for any other kind of Visa, he has a green card printer right in his garage...
Better call ajc9988:

Spoiler

 

Would love to have one of those printers lol.

 

Wouldn't we all! You can buy a knock off, but if you get caught... (j/k)

I love that show! How are lawyers like sperm? They each have a one in a million shot at becoming human!

Haha kidding of course, i really dont need one tbh specially since i love to move around a lot.

Random bench, till i find a way to install the 7700k in the Dm1 :

This is literally the first thing that popped in my head when I originally saw that they all share the same design now.

It would be awesome if @Eurocom Support or @Donald@HIDevolution offered the GPU with that model.

My friend is buying the Tornado F5 since it has a 1080 in a 15.6" form factor. I think the P750DM2 can handle a 1080 cooling wise.

4.9Ghz proper now Thanks @Prema

This is stock, BIOS defaults other than DDR4-3200. Either my temporary application of Kryonaut sucks, or I have just forgotten what it is like to not delid and use CLU because the temps are absolutely insane. Using max fans (no AC) CPU max was 96°C, so delidding and applying CLU can't wait.

http://www.3dmark.com/3dm11/11897399



Same run with identical BIOS settings in W10...

 

Terrible cpu temp results. Awful. If you have time it would be nice if you could try ICD before you go over to Liquid metal. For comparison vs. Kryonaut. People could see what they should use if they don't want to use liquid metal.

 

I don't want to take it apart two more times because people are too hard-headed and will use whatever paste they want to use regardless of the results. We've already seen that time and time again, with hundreds of examples by multiple overclockers. If I thought it would sway the stubborn I would, but I'd rather get on with my own fun with the delid and be done with it. People that want to live with crazy temps because they are scared of CLU or do not believe the results are as good as they are will still choose think whatever they wish regardless of the evidence to the contrary, LOL. I should have used IC Diamond to begin with instead of Kryonaut, but I knew I was going to be taking it apart to delid as soon as I confirmed that I had a good CPU and Kryonaut is just easier to wipe off. I also put Kryonaut on my GPUs and the temps are higher on the GPUs now by about 5°C compared to what they were with the IC Diamond that was on them before I installed the 7700K.

 

18C temp drop here by delidding the Kaby FLake...it was optional on 6700K, but from where I stand it's a must on 7700K.

 

So, it's unanimous! But, not a surprise. Merely more evidence that delid and CLU is the way to go. It was never really optional on 6700K, or 4790K if you do much overclocking. Temps are too high for good results unless benching on AC cooling.

And, anyone that thinks you're pulling their leg can see it for themselves... here and now.

 

Delidding and metal is the only way to go and is a match made it heaven with Prema BIOS. I can't believe how whorey these machines can be with a little TLC.

 

Wow, that was so easy, LOL... Crazy easy. And, during validation the CPU only hit 78°C without max fans running.

@Meaker@Sager Installed the stock 6700K and back up and running. Below is the info that shows up in my bios. Sager tech support had said this would work with my 7700K. I would like to get this right the second time. Could you help me out and let me know which Bios & ME I need to use to get the 7700K to post please.

Bios Version 1.05.04 LS2
KBC/EC Firmware Revision: 1.05.08g

@Johnksss@iBUYPOWER Have you tested any additional bios with the 7700K other than Prema Bios?

 

I've noticed that it's not so finicky as 6700k with voltage settings on adaptive. I going to move over to static since it's easier for me to know where I'm at.

Also I've mentioned this to brother John but since he mostly freeballs you might have encountered this. Have you found any kind of OSD CPU monitoring (HWinfo64 or even MSI) to absolutely screw with performance - not the usual few percentage cycles, but dramatically?

 

Not yet, but I have not really started digging yet.

 

I can't argue with that, but I'm working on it. Slowly but surely

 

Just read an interesting article about Kaby lake.

The AVX setting is only available on the Z270.
This means that the new coming boards of Clevo AVX support and the old Z170 not.
But this is serious.

Or did Prema make it, that we can also adjust the AVX clock?

Other clock multiplier from 45 to 44 would mean 41 watts less?
And thus less temperature!

 

I've heard from someone who helps people set up streams that Kabylake performs worse than Skylake for some extremely weird reason under heavy multitasking and streaming. But they seem to pass benchmarks fine...

If you want to dig some more, feel free.

 

@bloodhawk the technical reason is a setting called spread spectrum.

There are legal requirements about how much interference a machine can release at any given frequency. By oscillating the base clock by a fraction of a Mhz any interference from clocks/devices using that clock is spread out over a range of frequencies. The amount is still the same but due to it being spread over multiple frequencies, the interference on any given frequency is less. This means you can more easily meet the requirements without changing the hardware.

 

Im really not sure why its like that for you guys, my application of Kryonaut has been running exactly the same for the last 6 months now. Even on the desktop the temps have been the same after a month, even after a lot more thermal cycles.

I actually delidded my friends DM3 a month back that came with ICD and before delidding we gave Kryonaut a shot. Definitely weren't as good as after a de lid with CLU, but there was a 3C drop instantly. After de lidding however, 15C drop.

Gotcha. It kinda clicked after @Prema 's reply. I remember reading about this somewhere, but always forget about it :S

 

There is an AVX setting in the @Prema BIOS. It appears ONLY when a 7700K CPU is installed. It goes away with 6700K installed.

I don't know what that is, or why I should care. I have not Googled it yet. What is AVX, and should I actually care?

 

New more efficient instructions set. Thus generates more heat, so the offset lowers the clocks based on the multiplier (negative AVX multiplier x BCLK) you set.

 

AVX is the instruction set that abused haswell/Broadwell FIVR and caused them to draw ridiculous amounts extra power. They are present in Linpack and OCCT stress tests, but I am not sure of many other places. Skylake cannot run AVX from what I remember. Kaby Lake might be able to, but since it's so brutally demanding, they included an option where you can set a lower clockspeed target and lower voltage when AVX instructions are being run. In other words, it's a way to downclock for AVX if your motherboard/VRMs/cooling system cannot handle it without breaking your OC settings for the rest of your operations.

 

Hmm.... I see... while it probably means the exactly same thing...

This makes it sound like something that really blows...

This makes it sounds like something we could enjoy exploiting...

Thanks for both of your replies, bros.

An increase in watts used often means an increase in performance at the same clock speed. Using less watts is not necessary a good thing. If it lowers benchmark scores, and it could, that will not be a good thing. Not always, but often more watts is like more horsepower. 900HP at 10,000 RPM (same as clock cycles) is better than 500HP at the same RPM (clock speed).

I am generally skeptical about anything that uses less power. That carries garbage danger signs that we need to watch out and not get too excited about until we know how it translates into measurable performance (i.e. benchmark scores and game framerates). I'd prefer to do more with more than to do the same with less. I get the efficiency part is attractive, but to me it should just create more headroom to push harder and harder to use up what was saved and achieve better things by consuming more instead of saving power. I really hate the concept of doing more with less unless you use up the extra headroom you create.

 

No no. This is not to enable or disable AVX instructions themselves.
It is a KabyLake feature which reduces the core clock automatically once AVX instructions are used.
e.g you are using an overclock of 5Ghz for benching etc, but want the multi to drop like 200Mhz to reduce heat and increase stability for a 24h encoding or rendering run and not change your settings for that manually. Well this does it for you by detecting the instructions of an encoding session and dropping the clocks only for that.

 

There are three versions of AVX, the original, AVX2, and AVX512, if memory serves.

Here is why it matters: encoding often uses AVX to speed up the processing, but it runs way hotter. Previous generations of Xeons actually contain a dual step to use lower clocks for AVX than the set clocks. Not all programs use AVX and practically no games do. So Intel added this adjustable down clock so that you have one overclock for non-AVX programs and one for programs using it. As another comparison, check out heat output of prime 95 v.26.6 (no AVX), v.27.x (AVX1), v. 28.x (AVX2+). This allows the user not to leave performance on the table for situations using and not using AVX.

Edit: see Prema's post above mine, don't have to manually adjust!

And you have AVX and AVX2 instructions... Advanced Vector Extensions 2 (AVX2), also known as Haswell New Instructions.

 

I ninja'd you!

Just ordered my 7700K. Fingers crossed for a good sample.

 

Dang. The culprit is my English

 

Nope. I have not. Sorry.

 

But won't a negative multiplier still need to be set ? Like.on desktop boards?
Otherwise it might be a bit counterproductive.

AFAIK the KabyFlake Bios' are 1.06.XX

 

Now, that actually sounds useful. Like an automatic ThrottleStop profile in the BIOS that switches to a lower clock speed for video rendering and what-not. I'll have to play with that. If it doesn't lower overclocked benchmark scores it should be a nice feature to have. Thanks for the additional clarification. That's probably better than I would find elsewhere. It's usually all mumbo-jumbo gobeldy-gook instead of explained in simple practical application terms. I always want to know in 50 words or less "Why should I care?" and the complex technical explanations are often about as worthless as the tits on a boar.

 

Ok cool thanks. I just called sager again and after talking to a few people they said they are still testing the new bios.

 

Thank You!!

 

It will only kick in if the application uses AVX.

 

Someone asked about Windows 7 and kabyLake. Here you go. Completely stock.
http://www.3dmark.com/3dm11/11898661

 

Stock. Why is cache 40x? Stock in bios?

 

I don't understand?
