P775DM3-G Overheat Advice

Generally not. You should contact your reseller to confirm.

 

Not that it's relevant to warranty, but how long have you had the laptop for? Is it less than 14 days?

 

Why? Do you think of returning it?

 

Most of the world offers free returns within 14 days.

In other order of thoughts, you should probably play around a bit more with it, repasting should not break warranty, those laptops are kinda constructed to be opened!

 

I'm certainly disappointed with my P775DM3-G. For an enthusiast level laptop the BIOS is castrated and doesn't allow a simple under volt, the heatsink assy is inadequate and the fans are loud.

Following the re-paste and undervolt I have the temps under control, and getting great gaming performance but I'm still left with the noise and reliance on 3rd party software for simple voltage tuning.

It's too late for me to return mine, but I hear Eurocom are working on working on the Tornado F7. "If" it delivers, it will potentially be a much better machine.

 

Scan is not doing a great job here. They should be on top of these issues.

I had mine with 6700k and undervolt plus overclock fan profile in CCC kept the temperatures in lower 80C in Witcher 3.

Start by getting rid of CCC and then use the @John@OBSIDIAN-PC utility to install all the drivers and CCC. Download TS, and follow the steps discussed earlier in the thread by @Phoenix et al.

That ought to bring temperatures down to a reasonable range.

Edit : Repaste won't break the warranty. That is what Scan told me anyway.

I don't think in the close future someone will make air cooling quiter. Any laptop will be as loud as this one while keeping more or less same sizes. Its a powerful desktop cpu and gpu where heatsinks used to be big and with multiple fans on it. It's like Law of Conservation of Mass, all this voltage and power needs to go somewhere, you can't just get rid of it, it's turned into heat. The more ghz the more temp goes up. TBH im a little bit amazed kaby lake and 1080 can work in a laptop. My friend now is struggling to say he wants this laptop anymore, as he doesnt need so much power atm. He was thinking only that it will serve him quite a lot bcz of its power. Now he thinks it will die in1-2 years. ) He will probably get an MSI GE series now, with 1060 and a 7700HQ and with 120Hz screen which you can not find in uk@clevo and also cheaper. All because of those temps. Sad

 

I don't expect a laptop with a desktop 6700k/7700k CPU and 200w 1080GTX to be silent but in the case of the P775, I think Clevo could have done a better job

From the reviews I've read online the equivalent MSI's (GT73VR) with 1080GTX run cooler and quieter. I like the "L" shape design of the sink which seems to have a lot of surface area for heat dissipation (although I've not taken one apart to accurately measure), Aorus also use a similar design on a smaller scale. Unfortunately, since the MSI has a BGA CPU, it's a non-starter for me.

 

Just about all models of whatever ODM/OEM, use castrated BIOS. The only way out is to buy from https://biosmods.wordpress.com/partner/

 

We don't have em in UK. Unfortunately

 

We still have TS. And XTU if someone wants to use it. Under voltage-overvoltage and overclocking is still supported with these. Use the few options you already have, when OEM's refuse to give you what you should have.

 

Now in the P775DM3-G overheating boat too. Scan ran a 63hr Aida Stress Test without FPU or GPU ticked and to them the temperatures looked satisfactory. Tick the GPU and FPU box too and it hits the 90's after a couple of minutes with CPU throttling, even with FN+1.

 

Has anyone had any success with TS and a 7700K????

 

I'd be also interested in knowing how 7700K temperatures are behaving with undervoltage. @madeinholt have you tried running AIDA or any other stress test? How are CPU temperatures under load?

 

Yep, using AIDA and the temps are worse than the DM1 I sent back for a refund. BIOS 1.06.05 does not let anything other than the default -100mV voltage offset stick, I used the Obsidian Tool so I don't have the overclock settings in CCC to set a software under-volt and I am currently reading up on and trying to get my head round TS (whilst also trying to look after a poorly 2 year old)

 

I am sure 2 year old is much bigger a challenge than getting the temperatures under control. @Phoenix posted a good guide on TS.There is also a sticky somewhere in the forum.

 

Here you go, just change the multipliers to 42 and the cache offset to -150mV for both the Core/Cache

TPL are the power limits, maximize them like me, it won't hurt, the system will only draw the power it needs

 

@Phoenix I was just reading through those settings earlier in this thread, are they OK for the 7700K? I was trying to work out what I should have the multipliers set at or are you saying I should under-clock it at 42??

 

^ this guide worked wonderfully for me in bringing temperatures down on my system. As @Phoenix et al have pointed out, TS does let you undervolt the cache as well which is something that BIOS or CCC doesn't really let you do.

 

that guide is for the 6700K, hence why I suggested underclocking to 42 which is the stock clock but with a little overclock at its x42 on all cores not just on one core.

Be careful with underolting too much with Kaby Lake, I've seen 3 CPUs just fail after more than 70mV undervolt. When I say die, as in they work, but after a while, they are like damaged as the moment you give them ANY load or stress, the temp jumps straight from the idle 45C to 100C and the test stops.

the max I would undervolt a 7700K *only if it's overheating* is -40 to -50mV at stock clocks which are 45,44,44,44

Your and others' mileage may vary but I am just telling you my personal experience.

One of those Kaby Lake 7700K was mine, it was delidded even. the other 2 were for my friends, after an -80 mV undervolt, within a day, the motherboard got fried/no boot. Don't ask me how

 

True that

The Prema BIOS has the Cache Undervolt tied to the CPU undervolt, so when you undervolt the CPU, the cache gets the same undervolt unlike the stock BIOS

 

That is a bit scary, cpu going dead just like that. I wonder how does warranty works out in this situation.

On a related note, I think I will ask Scan people to run the AIDA test with CPU and GPU being stressed simultaneously to see how temperatures are behaving. And ask them to dial down the voltage and see what is giving manageable temperatures.

 

Cheers! They are now coming out with a default -100mV set in the BIOS. Would TS assume that as 0 and therefore any TS applied undervolt would be actually on top of the -100mV??

Scan are now getting a call from me too.

 

you see here's the thing, undervolting is an easy fix, not a stable fix. A better fix would be to repaste using the X Cross method and/or swap the CPU.

My Silicon Lottery 6700K Delidded can do 4.6 GHz on all 4 cores 24/7 with 0 undervolt. That's how a good CPU behaves but it was cherry picked from Silicon Lottery so we can't expect them all to be like that.

Mr. Fox is against undervolting, he overvolts and uses other methods like modifying the heatsink to make better contact so he can put Liquid Ultra which is not a great choice for us with stock heatsinks as the stock heatsink is a matter of luck, some make good contact with the CPU and others don't, so the easy fix is to use IC diamond with the X Cross method which is a thicker paste:

The X Cross method is the best in my experience as once the heatsink is fitted, it provides the maximum coverage with the least air bubbles

 

TS will try to override the motherboard value so if you set it to -100mV, then set it to -110 mV in TS, then -110 would be it as long as TS is running.

I hope @Papusan or @Mr. Fox @unclewebb can confirm what I just said

 

@Phoenix I have asked Scan specifically to repaste using the cross method. I will check again before they ship the system.

@madeinholt good idea. It would be much better if we could convince one of the Scan reps to join the forum. This will help them see what users are doing all over the world to cope with inherently handicapped bios and design choices of Clevo.

 

yeah this is why I ditched Clevo and went with MSI. Not buying a laptop again from them due to their horrible keyboards and I don't want to buy a machine and have to undervolt and do repastes / modifications to let it run ok on stock speeds. It should come out of the factory already setup to play right IMHO

I will always support you guys, just telling you what's my stance against Clevo now

 

From what I can gather this preset -100mV is not changeable, every change to it I have attempted results in it defaulting back to -100mV the next time I F2 into the BIOS.

 

offcourse it is, the default offset is 0mV. Hence why it's called stock voltage

 

Owning clevo machines is a bit of a labour of love. I can understand why you decided to go with MSI. Clevo should really be paying attention to users who are active in forums like this. A bit off topic, in one of the papers I worked on recently, we looked at people called 'gatekeepers' in MOOCs. Some fairly elementary graph theory based network analysis, and corresponding metrics tells us these gatekeepers are critical to maintaining the network and propagation(transfer) of knowledge. You take away these nodes, and network starts folding into itself. Clevo should really try to avoid situations where most active users start deserting the ship, it will be bad for the broader ecosystem.

 

This is Clevo...



and I cannot change this!

 

that's one buggy BIOS, it should be 0 by default

can u restore factory defaults and check

 

tried all that - this is 'stock'

 

That feels sad man...

I do believe as well that Clevo should be paying attention to it's customers. Investing even a bit more in R&D before releasing the product, or investing in software development and BIOS development would clearly clear them off headaches!

My honest opinion is that they should employ @Prema and he would do them more times the favor when it comes to BIOS changes

 

F3 sets the CVO to 0 [+] however after F4 and then F2 back into BIOS and CVO is back to 100 [-]. So the whole thing is borked. TS does diddly-squat to bring temps down with this BIOS. I tried 4.2/-147.5 and it could still boil faster than my very fast kettle. It just seems like the CVO is now totally perma-set to -100mV by Clevo. I have just been granted permission to do a non-warranty (14 day return) voiding repaste. Which I will do once dinner is done and the kids are in bed.
So far the DM3 7700K is far worse than the DM1 6700K.

 

This is not good news. Hopefully it is just a paste related issue. It is a bit weird though that TS isn't working . It worked like a charm on my system (w/6700K).

Just trying CCC with OC - to see if that changes the BIOS like XTU used to on the DM1.

Moments later... Nope back to -100mV - this is really *insert expletive*

Now trying XTU without CCC...

 

It beggars belief that clevo will handicap the BIOS in this manner. Quite unfortunate.

Well that's why we are all here. To share our experiences with our laptops.
I'll probably switch back to MSI I wanted before. I don't want to pay this price for repasting and hassle with it. I was wondering is there possible to get a barebone MSI in UK?

Otherwise I'm thinking of MSI GE72 7700HQ (if not i5 to get less heat)/1060/120Hz. which will also save me around £500-600 and no hassle.

 

That's why I got mine de-lidded and pasted with Conductonaut. Aida stress test for everything but the local disk and GPU gives me a max of 76C but averages around 68-70C on automatic fans. If I set fans to full it drops to around 62-65C.

I've only got the GTX 1060 model with me today, but if I turn on that test it goes up to average of 79C on auto and 73C on full fans

 

I think I will repaste as well soon, conductonaut sounds like a good paste. Picking the right paste seems an entire hell though...

 

Confirmed. ThrottleStop ignores any setting in the bios and under volts based on what your settings are in the ThrottleStop FIVR window.

I recently noticed one interesting thing while playing with an Asus desktop board with the Z170 chipset. The offset voltage that is set in the bios seems to be completely different than the offset voltage that ThrottleStop lets you access in the FIVR window. I think Asus CPU voltage management is completely separate. I have not yet heard of any laptop motherboards that do this.

To test for this, all you need to do is set an offset voltage in the bios and then when you boot up into Windows, delete the ThrottleStop.INI file before you run ThrottleStop. When ThrottleStop starts up, if it does not find a ThrottleStop.INI config file, it will read all of the voltage and overclock settings from the CPU. If the ThrottleStop FIVR voltage monitoring table shows the same offset voltage that you set in the bios then the two offsets are adjusting the same thing. On my desktop board when I set an offset voltage in the bios, the offset voltage does not show up within the ThrottleStop voltage monitoring table. The offset is applied to the CPU but the two offsets are completely independent.

 

That sounds very interesting!

What does each offset adjust then?

Does your desktop motherboard adjust maybe on a different scale?

 

This is not the default behavior of a P775DM3-G, i have no idea what BIOS you are using.
Let me know if you want me to send the correct latest version for kabby lake: P7xxDM3-KBLbios-1.06.04
I just tested our units and nothing like that happens.

 

^ @madeinholt this might work, but then again, I don't know if Scan people will be happy with the idea of you updating the BIOS (with respect to the warranty situation as Clevo is mighty tight-bottomed)

Yeah i guess you should ask them for the BIOS update then.

Do you leave it set to 'Adaptive'? I'm on the 1.06.04 BIOS and mine always resets if left set to 'Adaptive'

I'm pretty sure madeinholt is on 1.06.05

 

Guys, those who got it from scan... while you search for bios update, how does your laptop behave. 99+ degrees?

I get so irritated and desperate...
Don't you think of sending back?

 

You should probably look to delid and repaste

I also get 99C in certain conditions, don't be so concerned about it.

 

The P775DM3-G BIOS is now 1.06.05/1.06.03 EC, I have BIOS 1.06.05. In 1.06.05 Clevo have forced through a -100mV CVO, so effectively the under-volt is a default setting and one which cannot actually be overridden in the BIOS itself. Whatever you set in the BIOS, doesn't stay set in the BIOS! Although we do now have a rather pointless [+/-] box.

A total re-paste with Gelid Extreme dropped idle temps by about 5/6C however this did very little to control the heat when the whole system is being stressed at 100%.

At stock/default/out-of-the-box settings a run of Timespy puts CPU temps briefly up into the low 90's, unless the fan is set to overclock.

Even with all cores set to 4.2Ghz (x 42 multiplier) and a software forced -145mV Core/Cache Voltage Offset, a full run of Aida (all boxes ticked except drives) has temps peaking in the low to mid 90's. Going any lower than -145mv results in system instability, so I have knocked this back up to -140mV. This has reduced Thermal Throttling to a bare minimum. [Overclock fan settings]

The most system stressing real-world program I have been able to find is DAZ3D. Running a 20 minute I-ray render on stock settings results in a system lock-up within minutes of the CPU and GPU kicking in together. Using Aida, for the graph only, shows the temps hitting 99C just prior to the lock-up. With the 4.2/-140mV setting DAZ3D completes the render with temperatures peaking at 90/91C. [Overclock fan settings]

With fans FN+1 forced, temperatures are better but the dog farts and then leaves the room.

During my previous nine month long ding-dong over the P775DM1-G. This is a quote from Clevo “load in testing software we are seeing the CPU temperature of around 92~93 degrees. Even at 93 degrees, the temperature is still well below the throttle temperature/Tjunction max of 100 degrees on Skylake processors.”
