P775DM3-G Overheat Advice

The P775DM3-G was designed around a maximum specification of a 6700K and a GTX1080. Several months later the 7700K came out and Clevo, almost instantly, made this the top specification CPU. It would seem Clevo has realised there is a problem with the chassis not keeping a stock 7700K within their idea of satisfactory temperatures, hence this forced under-volt in the 1.06.05 BIOS.

Delidding is the only option left to possibly make this work!? In my opinion, a system should run 100% without all this piddling around. Clevo have taken a Ferrari engine and gearbox, and rammed it into a Reliant Robin.

 

Sending it back for a refund. Anyone have any suggestions for a decent £2500 laptop?

 

buy the laptop which I got, you will be much happier. works out of the box

don't mind the price in my review, that's because I put all those SSDs in there (check my sig). base price should be close to what you want...........

The keyboard is night and day better so is the screen, so is the cooling, no flimsy heatsinks........overclocked to 4.2 GHz on standard voltage and the fans don't even spin up to max speed while gaming

MSI GT73VR 7RF Titan Pro-425 Review By Phoenix

See:

Just ran a 3DMark11 test with the CPU overclocked to 4.2 GHz on all cores. GPU at stock speeds. GSYNC = ON. FAST SYNC = ON. Texture Quality = HIGH. Power Management = Adaptive

I can obviously get a higher score by setting the GPU to High Performance and the texture filtering to High Performance but I wanted to show you how performance would be in a normal users' usage scenarios, that is, with adaptive power management to not make the GPU always work on the highest clock speeds which wouldn't make sense if you're watching a movie or browsing the web, and I also kept GSYNC enabled but with FAST SYNC enabled for the Vertical Sync. that way, the max FPS isn't limited to the screen refresh rate but you still won't get any screen tearing.





Also look at the beautiful m.2 SSD heatsink that prevents the SSDs from overheating and throttling:

Internals of the laptop:

 

I doubt there is any laptop that will keep a 7700K from throttling unless you undervolt it.

For a lot of time i wanted to have our BIOS do exactly that, have a stock undervolt, i could not find a way of doing that.
It is a given fact that these CPUs can have big undervolt values.

Now is that ok or not? I´m not sure, the question is, with that BIOS version (which i don´t have and it´s not available in the e-channel for resellers) can you still change the value with throttlestop for instance?
If so then it´s irrelevant that the BIOS value is -100mv.

Actually i think it´s THEIR obligation to undervolt the CPU just like they did, if we consider that ANY 7700K wont work ok unless you add at least -100mv then it should be a stock setting. Why? Because some clients have no idea a CPU needs undervolt, and some clients have no idea on how to undervolt them. They should not have to know that.

The stock BIOS values should be the settings that work best with given hardware, i have no doubt that the best settings for most people is some degree of undervolt. Then for the most knowledge users you can just fine tune it, it´s unlocked right? That setting is not defaulting every time you enter windows right? -> I don´t know, please confirm this for me.

Second, even the 6700K was hard to make it not throttle, we are selling both CPUs with delidd, liquid metal and modded cooling system, even the P870KM1 needs to have the cooling system modded.
With a 6700K using the OC fan profile we dont need undervolt to make the CPU work perfect.
With the 7700K even with everything we do, you will still need undervolt. That´s a given right? Well read on.

Now i´m talking about settings for full unit usage, with CPU and GPU pulling at 100%, which is a RARE scenario.

BUT, now comes the complicated part, what messes everything for me is the fact that the system does have shared heat pipes. So if you pull just CPU you get X temperature and you probably have room to OC, and i remember with the 6700K you could even add voltage to OC almost to 5Ghz. If you only play games, well, the CPU will never reach very high temperatures, no matter what CPU we are talking about (unless your system was not well assembled). So the only scenario which is hard to keep from throttle is when you pull both CPU and GPU to high levels, and who does that? 5% of the costumers? Probably....

I use the AIDA EXTREME to pull both CPU and GPU, but i KNOW that is not a common real world scenario, games dont do that kind of usage, most of professional work won´t do it either. I just like to test my unit with the worst case scenario, if it can survive that well it´s ready for anything.

So when i sell a unit do i think this CPU should not throttle? Yes i think that would be great, but i also know it´s impossible under specific scenarios, at least for the 7700K. I also know that i can undervolt it a bit without it loosing performance, so i WOULD kill to be able to mod the bios to default at -100 or -120, in fact this is something i been after for so long that my Drivers app (my signature) will have a feature to load cpu performance profiles and the default profiles for 7700K all have undervolt.

As i said, default values, should be the best without loosing performance for the given hardware, and then advanced users should fine tune it to optimize it for their usage type.

Is the P775DM3-G one of the best 17" laptops i ever seen, yes!
Is the 7700K so hot that it is probably the only thing that would melt my ex girlfriend heart, probably true, yes, still i would not have any other because i can just fine tune it and have my system run perfect.

The only question that remains in my head, can you change the voltage offset or not with that bios? If not, then we have a problem that either CLEVO will solve (or i will personally slap them in the face) or we will just have to install prema bios, go home, profit.

 

Wont take any credit away from that unit. The fact that it is 15" is amazing!!!
Still he was talking about AIDA EXTREME, both CPU and GPU at 100% which is miles away of what you get with 3D Mark.
You can easly get 4.5 - 4.7 out of the 7700K, do a 3D Mark run and have zero throttle.

P775 1080 7700K pulling both CPU and GPU at 100%
Automatic Fan Profile
Stock Clocks
-100mv Under Volt



That´s AIDA
If we talk 3D Mark or most games, the system stays stupid cool....
All Stock:



If you fine tune it, it´s a monster....

 

@madeinholt It is rather unfortunate that you had to return the system. I just heard from Scan, they have received the new panel and it seems backlight bleed is much improved. I have asked them to run the AIDA with simultaneous CPU and GPU load to get a better idea of temperatures. Will update the thread once I get a response.


PS: Lol @John@OBSIDIAN-PC I did some stress tests on my ex-girlfriend, unwittingly ofcouse, to figure out the throttling temperature. Nothing could throttle her, even a 7700K running @ 5.0 Ghz wouldn't do the trick!

 

you only get a correct temp reading in AIDA64 after 3 to 4 mins not only a few seconds as shown above. The stress test becomes more aggressive once you hit the 3 minute mark

 

That picture is 39 minutes.

 

my bad, brain fart

 

Yeah... it´s amazing. Still this CPU is miles away more hot than the 6700K...

But what im doing as we speak with collaboration from uncleweb is making a new tab in my software that will have default profiles, like:
"GIMME ALL THE CPUS"
"Nahhh im just gonna game, no need to Melt my CPU"
"Battery life is my thing now"
"OC Level 1 - Noob"
"OC Level 2 - gimme better CPU bench please"
"OC Level 3 - it might just crash my system but well it´s life"

Hopefully having this in my app will greatly improve the way a user experiences the unit out of the box. No need to be a tunning expert.
Try out and load your profile, use the hotkeys to change the performance levels, the system is being monitored and you get alarms if temperatures are high

I really think a system like this can suit everyone looking for a high performance unit, but a) if you dont know how to tune it and use it in a right away for different usage scenarios then it´s gona be messy! b) if it´s not well assembled no undervolt value will save it e) inexperienced users are left in the dark too often.

 

That sounds great! Looking forward to the release.

 

MAKE SURE, REPEAT MAKE SURE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! that Nvidia OPTIMUS is turned OFF. meaning make sure that ur global setting is set to use nvidia graphics card ONLY! i had the same issue with a ASUS ROG G750 and this fixed it. Optimus kept running back and forth from Nvidia GPU to my INTEL one. Hope this helps!

 

I'd have imagined that Optimus would be turned off by default in these machines.

 

ignore the above post. There is no Optimus on the P7xxx and P8xxx series The Intel HD Graphics is disabled eternally in these machines.

 

@John@OBSIDIAN-PC if I had temps like that out of the box my toys would still be occupying pram space. That's not delidded or anything? just with turbo boost disabled? I use Aida as a reference because it pulls only slightly beyond what a render in DAZ3D does, so to me it gives a good idea of real world.

You can still use CPU OC/TS or XTU to alter CVO within windows with 1.06.05

 

@John@OBSIDIAN-PC

So does a 6700K in the same unit run cooler? Could it be possible I have a bad CPU?

I have asked if they could send me out a different CPU to try in it, if they will, before it goes back for the refund.

 

Thats how our clients get their units out the box.
We offer delidd, Conductonaut and we sometimes mod the coolers. Whatever it takes.

If you can stil tune the CPU i actually think its a good thing to have a stock undervolt value.

 

Our 6700k dont even need undervolt.
Super cool and ready for a lot of tuning fun. My daily is at 4.8

@John@OBSIDIAN-PC In the screenshot you posted of AIDA running for 39 minutes, was the 7700K unmodified? Did you have turbo boost disabled (it is enabled by default)? What was the room temperature?

With my room at 21.4C, with a -145mV undervolt and turbo boost disabled my idle temp is 37C. According to your screen shot , your idle was 28C. [Fans on auto]

Could I just have an awful CPU example?

 

The 7700 was with stock BIOS settings but with -100mv.
The 6700 does not need undervolt.

Everything else is stock but with delidd, Conductonaut, cooler mod.

Again you make me feel like a bit of sucker for not buying from you guys...sigh...Scan have been very nice to me with regards to upgrade et al but I think you got a really good thing going with better thermal paste, fan mods, and delid etc. Do you guys do exchange deal

 

Nahhh just do it yourself.
Its easy.
Use our website chat system and ask for help from our tech team.
If they are not trying to win against me in a Quake1 match then they will help.
Just ask permission from your dealer so you wont lose warranty.

So a 7700K will not work in a P775DM3-G and run at stock settings without a delid.

 

Scan won't permit a delid, question asked this morning

 

I wonder if they would be happy with different thermal paste and fan mods.Maybe a better thermal paste with some minor modding will solve the heating issue.

 

What paste do Scan use?

 

Arctic Silver 5. In my experience of dealing with them, they did not appear entirely comfortable with the idea of liquid metal pastes. Well that is my impression anyway.

 

Liquid metal should ONLY be used on a re-sealed CPU.

And no, 7700k with stock settings will throttle with the usage you intead. You need some degree of undervolt.

The 6700 is way more cool.

Very rare a i7 breaks. Delidde your processor itself and if something happens... Take this on your own gown(You loose $300). Whatever you choose, this is the best and only option.

 

I'd say Arctic silver is pretty rubbish in comparison to other non LM's available these days

 

It is actually £339 in blighty but I get your point. i will definitely do a repaste (non LM kind because of the warranty issue). What compound (non LM variety) do you guys recommend?

 

Well I was using Kryonaut before switching over to Conductonaut (LM)

 

US $309.99 http://www.ebay.com/itm/Intel-Core-...id=100623&rk=1&rkt=6&mehot=pp&sd=291974111044

Gelid Extreme, ICD or Grizzly Kryonaut.

 

I might do that. In anycase, this is all academic at the moment. i need to do a few tests to understand how temperatures are behaving.

@Papusan how would the US import affect the warranty? And that reminded me, I have to sell my 6700K.

 

I don't know. I'm not from over there. Buy hardware in my own country.

 

Oh I am sorry I thought you were based in UK too.

So scan just contacted me, and results of stress tests are; well not particularly surprising. Without any undervolting and what not, running AIDA's CPU and GPU stress tests simultaneously results in 94 C max. I think with a bit of tweaking, I will be able to get the temperatures under 90C. Though I don't know how the system will behave with an over clock. Might be worth investigating once it arrives (on Tuesday)

Their gaming benchmark tests (no idea which one they use) results in 80 C and 56 C on CPU and GPU respectively.

Scan use MX-4. I re-pasted with Gelid Extreme (twice to make sure I had the right amount on).

 

Scan are very kindly sending me out a 6700k to try, before we actually pull the trigger on the return.

 

They make you pay £5 to 'upgrade' to Arctic silver...Let's hope 6700K does the trick. Mind you, my 6700K was touching 99C and throttling before I used TS to optimise the voltage (-150mv). After that, it refused to go beyond 86C

I watched every 7700K delidding video on youtube whilst going off to sleep last night (a fantastic cure for insomnia!). The 3d print job looks like the cheapest and quite an effective option - without stripping down the Stanley knife.

 

This is a good scientific guide to paste.

 

Brilliant. I just put an order for Thermal Grizzly, so we will see how much of a difference does that make.

I have 14 days from when I receive the 6700K!

I will try and find the article I ripped that list from, it also gives info on ease of application for all the various pastes. Gelid Extreme works better if you pop it in a bag, in a mug of hot water before you apply it, very quickly.

 

I wish my daily would go higher than 4.0 man...

Any kind of advice you might have, my ears are eager to listen and my mind is open. repaste is underway for me, but delid , I just don't have access to any delid tools.

For how long and how hot should be that water?

Seems I'm also getting gelid extreme.

 

Having much the same issue with a Scan P870DM-2 running a 6700k/32Gb/1070 sli.

Used to idle at about 35/40c, when asked to do anything cpu intensive bang straight to 90/98c (well 5 mins) and welcome to throttle hell.

A few days ago decided to repaste, glad I did. Who ever done the paste job must have been a bricklayer before working at Scan. The paste was pastered on, cpu and both gpu's covered in Arctic Silver 5.

So after cleaning everything off, I used some MX4 (only stuff I had handy) and fired up. Now running at idle 25/30c and when doing anything cpu intensive 90/92c (after about 30 mins). So much better, but anything much above the 35 min mark (running the cpu at 100%, when encoding video) bang welcome back to throttle hell.

I've got a 7700K sitting here ready for this machine (When Scan get their act together with sending me the Bios upgrade), which I'm sure do exactly the same as the 6700K so I may well be delidding 7700K just to get it running a bit cooler.

Clevo really need to fix the bios on these machine's, which I'm pretty sure they are overvolted by default. Yes TS helps but its yet another layer of software to deal with.

Maybe Prema could do a "Prema Lite" bios for these machines, just arm up a working undervolt.

 

You can't use these test results and say that this is the gold standard. Most of these tests are done on a test bench / desktop cooling and not done on the weaker cooling in laptops. The temp difference between Liquid metal vs. top notch conventional thermal paste on eg. Haswell 4930Mx is a lot higher than the stated 1C in this thermal paste guide.

50C - 10 min. Then start to apply the paste.

 

Have to agree. LM is great stuff but does need good heatsink contact. My P570WM didn't show a lot of difference with LM or a good standard paste, but then the heatsink was warped badly. But then when I put a 0.25mm C101 copper shim with LM on both sides I did see a 10/12c drop.

There are a lot of factors in cooling.

 

Water at about 60C and left it to cool. Gelid tube needs to be in a zipbag or something - between 40 to 50C leaves the paste runnier than it would be room temperature.

 

I didn't.
