Clevo Overclocker's Lounge

So far from what I seen, they have the same number of cores as the 7700K and 7600K, rumor saying the "7640K" might have Hyper-threading. If that's the case, the difference between i7 and i5 is just 2MB of L3 cache. Wish they could grant 10MB cache for "7740K", if it really exists.

 

Sager/Clevo bios.

The question is whether Clevo is going to improve the cpu heatsink in current models *if* this so called 7740K will be the next chips. Maybe we will see new models? 100w chips is still an increase in heat vs fomer 6700/7700K. Thoughts on this @Johnksss@iBUYPOWER @Prema @Mr. Fox

 

Me? I'm all for more "real" watts. Which means possibly a real increase in clocks. Provided the chips are not at their max air clocks now.

Side note.
5188.56Mhz on stock bios.

Yeah, more real watts Normally will an increase in TDP mean a heatsink re-design. Not all delidde the processor and re-applying better thermal paste. Maybe all depends on how high TDP the heatsink is designed for. I expect Clevo didn't know about a increased TDP for the 4 core i7 when they designed the Cpu heatsink.

 

You would have to take that up with the new version ( P870KM1/P870KM1-G) since our machine wasn't really made for the 7700K.
Although that wont stop me from running the newer cpu in here with a new motherboard and possibly new heat sink if they were to make one..

 

All depends if Clevo knowed about Intel's roadmap for Kaby lake 4 core i7 (with the higher TDP). If not, maybe Clevo will wait and put it in the next model. Maybe even a full change. 7700K can be the last step in this model series ( P870KM1/P870KM1-G). Of course can you probably use 7740K with a Prema mod, but newer models intended for this new Kaby chips will most likely have better cooling(if you then can't use the cpu heatsink from a newer model). Clevo must take a step up in the cooling capacity, if they not already have done it with the current new models due higher TDP.

Edit: Maybe we'll see some changes who are wanted, if Clevo will use a possible 7740K ? http://forum.notebookreview.com/thr...unge-phoenix-3-0.800081/page-14#post-10433845

 

I don't know. I'll just wait it out and see what happens. Since none of that would change my mind in getting a 7740K.

Other news:
Sager/Clevo bios as some dips going on....
This was first test
Second test had one dip in gpu test1.
Not perfect, but sure is better from when they started.

 

Maybe we can see speed up from Intel

 

More testing of bios before I go back to my Premamod

 

Hmmmm might have to hold off getting a 7700K now

I lied...these look like they're going to be for the new X199 or X299(w/e) HEDT platform (socket 2066) not for Z170/Z270 (1151)

 

Someone in the http://www.sweclockers.com/nyhet/23351-intel-kontrar-amd-ryzen-med-core-i7-7740k-och-i5-7640k site should be fired


"Furthermore, there is talk that Intel prepared two new processors in the family Kaby Lake for socket LGA 1151. The first is a new flagship that goes under the name Intel Core i7-7740K which the base and turbo frequency goes up to 100 MHz. A direct consequence of this is that even the TDP value takes a leap up from 91 to over 100 W"

 

What are people running load line calibration wise? Anyone done some playing?

 

I tried upping the duty cycles a bit, but that seems to make me hit the voltage wall much faster on the DM1.

 

50 in the DC levels can stabilise the voltage and temps. However you get stability issues so I'm looking for a setup that helps further.

 

Please don't hit me, but is Arctic MX bad in any way? Seems that every single Romanian shop only has Arctic MX as thermal paste? Any recommandations on better options, or what arctic is the best, please ?

 

I kinda had had it with the thermal solution I am running on and want to see what I can do by a repaste, before I consider a delid.

 

So... Seems I can find anything that is Arctic up to Arctic Silver 5 or cermaque or something, and anything that is Noctua or something.

Arctic Mx-2
Arctic Mx-4
Arctic Solver Alumnia Thermal Adesive
Arctic Silver 5
Arctic Silver As5
Noctua NT-H1
Arctic Silver Ceramique 2

ID Cooling TG 31
Antec Formula 6


And those would be it (?)

I was actually looking for Konduktonaut right now, but there is no Konduktonaut nor any Liquid Metal. There is very little or no other paste than the ones I mentioned above in the entire land of Romania

 

Since my temps to reach 100 with my actual paste job, the best question is which compound will reduce the peak temp and doesn't degrade at those high temps.

 

Staph!! Order outside Romania. It should not be that difficult? Either continue with to high temp or do something about it. See... Coolaboratory Liquid metal, ICD, Gelid Extreme or Grizzly Kryonaut. Prolimatech PK-3 may be another option. Most of the others that you posted here is wasted money and time.

 

Thank you for letting me know!

Ordering something from outside of Romania is not overly hard if it is in any store around central Europe.

I have no idea what happened but most good pastes are out of stock around here...

Arctic mx4 looked like my best shot to buy from Romania. From the ones you mentioned, it seems that there is a single shop that brings both Gelid Extreme and Kryonaut. Kryonaut would take a few days to arrive and it's considerably more expensive. Either would cost me about 15$...

I'm not one to argue and this might be similar to how headphones are for audiophiles, but which is the safest to use? I know that Liquid metal is tricky and ICD can leave scratches on the surfaces. So from Gelid Extreme and Kryonaut, which is safer and more hassle free? Also which has better performance?

Is Arctic Mx4 that bad? Asking because on 99% of Romanian forums it is the most recommended paste so I gotta wonder why

 

MX4 and AS5 were the go to desktop pastes 7+ years ago

They both work great if you can get good fitment of the heatplate against the CPU and work the paste away from the edges of the CPU so they don't touch the air and dry out.

The problem with laptops is they move around, and any little flex that might lift an edge on the seal for the paste to the air can cause drying out.

MX4 has been reported to last as short as a month or two before temps start going up, but others get a year or more. It depends on how well the parts seal the air gap.

Since you have already repasted, I'd spend the extra $15 and try Gelid or Kryonaut.

Be sure and watch videos and read text descriptions on getting good coverage, and mind that edge of the CPU to air gap - make sure it is sealed, any paste will react with oxygen and heat over time to degrade the cooling.

 

Give a damn in the cost!! You ruin your enjoyment with a low end thermal paste

You forgot that the heatsink for laptops doesn't have same good pressure on the hardware as the desktop variants.

 

Thank you!

This is interesting!

Between the two, am I better with either? I can order both, but which is better in general?

Also, this will be my first time ordering paste and repasting so I'm not sure if I will do the best job in the world. This is the first time I hear that I should mind edges of CPU, I'm not sure what that means or what am I supposed to do about it... Any link to a video would be very handy as on youtube most videos I found with ease were for desktops are were about pea method vs X method... Which method do you recommend for P775?

Thanks a lot for your help!

 

I almost forgot that 2011 - the year when a romanian won OC competition using arctic Mx4 - was about 6 years ago...

 

Kryonaut came out a while ago, and these guys, this video, were the lead instruction for release and application, der8auer.

I'm a believer in hand tuning the application, and not relying on spread from pressure via dot / X.

After hand application I pull paste using a card to remove excess, and then I trim a 1/16" / 1/8" from all the edges so the paste doesn't touch air.

The Kyronaut paste tube comes with an applicator to assist in hand spreading, check out this video with a comparison of methods:

 

I use and prefer liquid Ultra if the heatsink is ok. I will not denigrate Grizzly Krynonaut because I have not used this one, but I have used Gelid Extreme earlier. I can highly recomended this paste. Regarding the application... I prefer the X-cross method. Aka let the heatsink make the actual application. First put the syringe with thermal paste in a plastic bag and put it in a cup with hot water before the application. The paste becomes softer and will spreads more easily.
The not so good thermal pastes, is often softer and easier to spread out. And those of better quality are usually thicker in consistency. Hence more difficult to spread. But you will get better results in the end

 

Thank you for the in-detail explanation! Sounds like I could use some of that, but the instructions also sound very hard to follow... I hope that I will be able to just to it okay for the first time and take it from there

That is very good to know!

Thank you!



By the way, just tested! Throttling during gaming is real. CPU was staying around 70C-80C, so no 95+C and the GPU around 80C. My CPU was throttling to around... 2.5GHz as reported by other users. This seems prelevalent while using both CPU and GPU at the same time. Ntz Ntz Ntz, Clevo actually did screw up. I will start by a basic repaste and return with the results.

 

So my temps on CPU are still too high and what's a bit bad is that my voltage spikes badly. 1.445 Max voltage spike while in maximum CPU usage, it generally hovers around 1.27 - 1.3

Should I set it to static voltage and set it to 1.3 to avoid problems?

 

Usually the notebook motherboards tend to pump it in a bit, i've been playing around with the load line calibration settings and they are tricky to get right.

 

Static voltage won't help you with voltage droop (I think, someone correct me if I'm wrong).

 

What LLC settings does the bios have? I can only compare it to my desktop...

@Meaker@Sager - for example my Asus board has 8 levels for the load-line calibration. I have it set to level six, which puts the droop at a level that what you set is about what the CPU goes to for voltage under load. You might have a bit higher at idle, but it is idle and not generating as much heat.

Skylake does not do static voltage at all. You can only influence voltage. What speeds are you holding for 1.3v on average?

 

Thank you for your answer!

I was originally on 41X with 1.35 average voltage

Right now I tried playing with the voltage and noticed something really strange. I set the multiplier to

40 for 4 core
41 for 3 core
42 for 2 core
43 for 1 core

When I did this, the system got all unstable on me and kept disconnecting the GPU at random times (under load) so now I'm testing how it works with 40X.

The throttle is there as everyone pointed out before, and I surely do recommend that everyone get theirs P775 from a Prema partner if possible! Stock BIOS is really bad for performance...

 

I am starting to feel your NOTEBOOK has a problem and not your BIOS specifically...

also you should keep your CPU equal for core clocks. having multiple stepping is a bit of a problem for stability.

 

I also thought that my personal unit has a problem and sent it back to the reseller, he tested, installed something on it then it came back working. It might be a context of the apps and settings I am using...

But throttling during load of both GPU and CPU was mentioned by many more than me. What happens - you use the GPU for a game, like Deus Ex: Mankind Divided. Then the CPU throttles to 2.5GHz for no reason, even if none of them isn't reaching any critical temperature nor the CPU wasn't used more than 50%, It just does that and it results to dropped frames. Seems that both P870 and P775 do that on stock BIOS.

The condition for this to happen is for the load to be sustained for 1-3 hours - so an intensive session of gaming. It won't happen during benchmarks.

 

Not really.

 

When fighting for best undervolts I found it's most stable locking them all, but I've only tried it on Haswell mobile

 

Remember Skylake/Kaby pick their own voltage. Put one core higher than the other is wasted. Run all same a @D2 Ultima suggested, and play with voltage offset is best.

 

Benching with +791 MHz VRAM on 1070 on my 870DM1.
Effective clock ~ 9600 MHz, no hardware/voltage mod.
Fire Strike: http://www.3dmark.com/fs/11661315


To squeeze out the last MHz from the VRAM, this is all I needed (the temperature):

 

Today I learned a PC does not have access to Sleep Mode without GPU drivers installed.

 

You manually program in the mOhms.

 

Seeing all those results and I must say that most Clevo owners are really that hardcore in pushing their machines to its limit.

 

Not even close. This is a *SMALL* sample size of owners. There are many more on other forums out there, but the vast majority of Clevo owners do not push their systems to the limits... and also the vast majority of Clevo owners don't know they're a Clevo owner.

However, the community here is rather tight-knit, and welcoming to new entrants, unlike many other forums I've been to where they ignore or attack anyone wanting some help. I was a noob once, I thought that a 128-bit memory bus on the HD Mobility Radeon 5870M didn't allow it access to its full memory size haha. And look how far I've come.

 

Yeah all the way up to 512bit and 16GB of vram (that's how SLI works right?)

 

Oh god. I came such a long way xD

 

Everyone has to make the same journey, in some cases it was easier dropping in earlier

 

Indeed. I'm still impressed with myself, though. I got really serious only about 4 years ago (though my streaming learning started all the way in 2009).

But then again, I REALLY like this stuff.

 

Well there is always more to learn for all of us
