Undervolting is only a huge threat to stability when you undervolt as low as you can go. Even a small undervolt can help massively with temperatures, since the power draw is proportional to the square of voltage.

 

Run your new system with stock voltage and see how it goes. If needed, reapply new paste and try again. If you want/need to undervolt, then test your machine in every ways. K chips is well binned so you have headroom for a slight undervolt. But do a lot of test for stability if you are afraid to lose data. Backup is of course important anyway.

 

It's not any more "dangerous to data" than any random BSOD is.

 

-100mv is rock solid at 4.2 for me. I ran -150mv at stock clocks and it was absolutely fine. I didn't even try to go any further as the temperatures were fantastic.

I've tried my best to completely stress the machine as far as I can and I've not hit any limitations at, or anywhere near, stock clock. I run the machine on the overclock fan profile for the most part as I feel the normal profile takes too long to kick in (65C approx.). The overclock fan profile is nowhere near as loud as Fn-1 (It's not F1), especially when you are just browsing around etc.... it's silent.

Currently I'm seeing maximum temps of 85C on the processor during all my benching, testing, stressing, etc, etc, etc. I'm more than happy with that. Actual usage sees me hitting around 70-75C maximum.

However, I would stress that this sort of laptop isn't for the average user. You really need to be happy to tweak and test on your own, find your own limits and do your own benchmarking. Following other peoples advice can only get you so far.

 

Okay ran some test with Witcher 3 on Ultra. It looked amazing, and never dipped below 60fps that I noticed. Ambient temp was 22C.

Auto fans:
CPU peak: 90C
GPU peak: 88C
Keyboard surface peak: 42C (most of the keyboard was in the low 30s, one spot was a bit warmer)
Peak fan noise at head level: 54dB, which I'd call audible but pretty quiet.

Overclock fans
CPU peak: 78C
GPU peak: 71C
Keyboard surface peak: 40C
Fan noise peak: 60dB, which I'd call annoyingly loud. You'll probably want to use headphones. It's basically the same as Fn+1.

Tried some Dota 2 with max settings, running at 75Hz. No real difference between fan modes, peak noise was 52dB (audible but definitely quiet), peak CPU was 61C, peak GPU was 53C.

Also tried some WoW, peak CPU was 62C, peak GPU was 55C. Still ~52dB.

So basically for any game that's really going to push the system, you'll probably want to use overclock fans and deal with the noise. For any game that's not super demanding, it's going to be fairly quiet and cool.

 

Thanks a lot for the trouble! It seems too loud for me though... just for comparision, the MSI gt73vr looks a lot quieter. Check this video:



Why are the clevo so loud? Could it be the fans?

OCCT is still running at the moment so I'll grab more data as the time progresses.

I'm very pleased with what I'm seeing...

 

I'm waiting for reviews of the 120 Hz AUO IPS screen before I pull the gun. At this rate I might as well get Kaby Lake huh... The Samsung 960 Pro SSD is also a very nice plus since it's coming out next month. Quite happy that everything's refreshing at once.

Doing the test infront of laptop or near the vents will yield very different results, Gentechpc video review has max fan on the MSI GT73 at 79-80 decibels, which is louder than the Clevo from what we have seen here, now the P775DM3 has a desktop CPU, it is normal that the Clevo fans have to work harder, 45W card vs 95W card and all, so even if the decibel difference is 10 or so decibels that isn't bad at all, specially if it is keeping everything cool, ofcourse someone can just do a test with the testing device in front of the laptop like the MSI test, on max fan profil and on automatic, for a fair apples to apples comparison .

 

I found the current control centre to be pretty rubbish. I even tried the latest .83 build and my system fans come on a lot more often and randomly than they do if I go back the an older control panel ending in .50. You do lose the ability to over clock inside Windows but it means my system runs a lot quieter without random fan speed ups

 

Feel free to enlighten me guys. How likely are we going to see 4K@120Hz in, say, 4-6 months from now? Or perhaps a bit longer and we'll get to the next refresh cycle aka DM4. Or even longer in an entirely new range aka insert name here ?

I'm sure this is a sore point for many like me who's still holding the need for a new Pascal-powered beast at bay. For those who already pulled the trigger I've seen quite the interest in upgrading once the panels are available.

Had a look at other so-called 'competitors' (*cough*Alienware*cough). The best they could deliver (on paper) right now is QHD@120Hz. But I'll be damned if I succumb to the BGA horde. The last BGA machine I ever owned was an HP dv7 8 years ago.

 

That's very cool indeed! Do you plan to stress test it with a beefy overclock? Lets say 4,6 or 4,7Ghz? Should be in the 70ies region.

 

I've been running it at 4.6GHz all night and it has been very stable. The temps are amazing with the Delid and Grizzly Conductonaut.

Right now I can hold 4.8GHz and am tuning the voltage to be able to drive it at 4.9GHz. I'm almost there. Once I find the sweet spot at 4.9GHz, I'll run OCCT to stress the CPU.

As of right now my wPrime 32M's at 4.9GHz are in the 4.1's (Seconds) ...

 

All rightinger! If I ever can lay my hands down on a Kaby Lake, I know where to go in the teaching!

 

If you really want to test stability and heat, use Lynx (at least 4096 mb load) or Prime95 smallFFT test. OCCT might be good too but if it's like Everest stress test, then it might let unstable overclocks/undervolts pass. The fastest way to test stability is to do a 20 run 4096 mb in Lynx, if it passes without errors, you are good.

 

4K at 120Hz are not too far away. Of course, those 120Hz are gonna be pretty damn worthless, if the reaction times are 30ns and higher .

 

Also, we'd need to find a GPU that can push 120fps at 4K resolution.

In a few years, when NVIDIA introduces the Hawking GPU generation, and we all have liquid nitrogen coolers in our laptops, then maybe.

 

We're getting there.

I refuse to acknowledge this... thing's validity. A laptop that can only be used at full capacity in a single place, unless you either know someone who also has a docking station, or are willing to carry that glorified ghettoblaster with you? No, thanks .

 

Remember what the first "mobile" phones were like? That's where we are now.

 

I still haven't heard a laptop speaker that I'd use for more than watching a random YouTube video, but the headphone jack is pretty good, without a doubt the best I've had on a laptop. No noise at all on it.

I'd previously been using a Dragonfly amp/dac on my old laptop but I'll probably not bother with it now.

 

Fair enough, but I'm still glad that Clevo's desktop-grade cinder blocks exist, even though the company might have to significantly rethink their cooling solutions for the upcoming hardware generations. I'm not asking for the portability of a laptop, but I do expect to be able to easily relocate my system. That's why I'm buying it in the first place.

 

People are forgetting the jump in power between the 980m and 1080 which has a higher TDP than the desktop 980 even did.

With some thermal pad tweaks we are pretty much there.

 

@Georgel To expand upon this, basic theory of operation.

Realtek ALC892/ALC898 -(SPDIF digital signal)-> ESS Sabre32 ES9018 DAC -(left/right analog channels)-> pair of TI LME49720 opamps (1 each for left and right channels) -> single TI OPA1622 opamp (if enabled, otherwise bypassed) -> Heaphone jack

When you plug in a headphone, it will measure the impedance and report it back to the EC. The impedance is shown in the Clevo Control Center software. After the measurement, a relay is powered to switch the headphone jack signals from the impedance measurement circuit to the headphone output from the LME49720 + OPA1622 amp. Also depending on the impedance it will enable or disable the TI OPA1622 opamp.

The LME49720 opamps are SOP8 footprint, so you could mod it by replacing the chips with a hardwired DIP8 socket if you really wanted to. The OPA1622 is not so easy to replace, you would need a hot air rework station.

The internal laptop speakers don't use the DAC.

 

When you plug in headphones you can actually hear the test signal

 

Thank you very much!~

Now I'm curious if I can force the headphone amp and certain parts on or off, since I'm using both a ie800, an ultrasone dj one pro and plan to get something like a DT880 at 250Ohm, so there is a lot of variation in my listening equipment and I might find myself in the position where the auto-detection circuits don't work the way they''re supposed to.

The design is very interesting, I wonder if it sounds better than my Fiio X5ii, even though I highly doubt this.

At any rate, it should be more than amazing for both games and light music listening with most headphones.

What I wish they would start implementing are 6.3mm ports for headphones, as using adapters is really awkward when listening with headphones that feature big jacks...

 

Ah I'm with you mate. I'll be including detailed info about the sound in my review. As a bit of an audiophile myself, I'll see how the sound compares to my FiiO E17K ALPEN 2 AMP/DAC with my weapon of choice....Sennheisers.

By the way, anyone can confirm if the GPU vRAM is GDDR5 or GDDR5X? The manual states just GDDR, nothing more..

 

The GTX 1080 is GDDR5X for sure, while the 1070 and 1060 are GDDR5...

::iunlock::

 

and that's why the 1080 is really expensive compared to the 107/60

 

One strange thing I've had happen pretty regularly -- sometimes when I start up a game and it's in borderless windowed mode (fake fullscreen), my performance is TERRIBLE. Like, 15-20 fps when I start up WoW or Witcher 3. Going fullscreen fixes it, and if I go back to borderless windowed, it's fine as well.

No idea what's causing it. Anyone else seen something like this before?

 

im pretty sure the 1080 is gddr5 in mxm form, not gddr5x.

Awesome customer service from Donald S, What do you guys think of the setup?

 

Very nice mate and congrats! When is the ETA?

::iunlock::

 

Well, you're wrong. It's GDDR5X.

 

Ya, ETA seems to be the big issue with these. My reseller doesn't even have a chassis for my build

 

Lol my bad, iv seen a bench and GPUZ as gddr5 which is weird. Thought gddr5x was rumoured only. Glad to know.

Calm down

 

Well then, if I'm waiting for Samsung 960 Pro then I might as well wait for the 120 Hz IPS screen, then I might as well wait for Kaby Lake.

Then I'll wait for the chassis.

(jk hope they get stock soon.)

I am also interested in this. Because of problems with external display I had to return my P650RS-G. Now I'm consider buying p750dm2-g but if it has the same bug it's definetely no go.

Could you please test your p775dm2/3 or p750dm2 for this problem?

 

Should also wait for Volta and Cannonlake jk

All these delays really adds onto going against the grain of the never ending cycle of technology waiting game and new releases....always advancing...shortening the cycle like never before...

Hang in there!

 

Why doesnt Clevo offer the FHD 120hz 5ms 94% ntsc screen that MSI offers in their gt73vr laptops?

 

any reviews of P750DM2 yet ?

 

Not that they don't, but rather it's up to the resellers to swap out the default screens for whatever else they're going to offer. In this case, I only know of Eurocom openly offering it (AfterShock offers the IPS version instead, which Eurocom offers too). There are delays and waiting times etc so I'm still holding out for the moment.

Hadriel

 

Just tried a delid with Grizzly and all my temps have gotten worse. Is there a burn in time with this stuff or something? If things don't improve I'll be going back to AS5. So much for the new gen stuff. I'm seeing 89 on full load at 4.2 with fans on OC and a -150mv undervolt.

 

Unless the new screens arrive by November, I'll probably just buy an SKU, then get an aftermarket 120Hz screen later on to replace it myself.

 

No there is no burn in time.

Due to me having seen it over and over again, I'm going to bet that there is not enough LM on the chips. You have to be more generous when applying LM or paste in general with notebooks.

Or...the chips are not making good contact with the heat sink.

Open it back up and add some more LM...it's not the paste, trust me...

And for goodness sake please don't have as5 to something you'd resort to when there's Grizzly Kyronaut and Gelid Extreme.

Add some more LM and report back...also it's highly recommend to tape around the gpu with electrical tape just in case as an insurance plan and pcb stain prevention.

::iunlock::

 

That's a TN not IPS right?

 

Yes but It's the fastest 120Hz FHD panel with minimal ghosting vs IPS

 

Plus, if reviews are to be believed, its visual quality seems to be pretty much on par with a solid IPS screen, albeit with some calibration required on the GT73 to bring out its colour fidelity.
