You can download the manual for the DM from Clevis website. The 15" model if configured correctly can take a SIM and the manual shows photos and more specifics about it.

Thank you !

The sim card emplacement is under the battery.

 

Interesting, ok let me clarify this If for example I have a i7 6700k 91w cpu you mean I could change it to make it act as a 6700(non K)65w with xtu tuning and even get the same lowered wattage of 65w even though its really 91w?


And if so could the same can be done with the 6600k 91w to make it act as a 6600(nonK) with 65w lowered performance ?

 

Hi guys, I ordered a p770dm today. I'm wondering if quick sync work with this laptop. My gut reaction is that it wouldn't since the igpu is disabled but I'm not sure.

 

some new info here - http://www.eteknix.com/apacer-reveals-pricing-3000mhz-nox-ddr4-laptop-memory/

Also wondering what the timings will be fore these as well as the Samsung 16GB so-dimms that mythlogic, sager, and lpc-digital and other vendors are placing in some of these units.

 

I think a moderator would need to do it. ProFX's "profile is not available" = banned, no longer a member...

 

yes, u can adjust clocks for 1/2/3/4 cores, wattage, amperage, turbo boost clocks and duration, etc. dont worry so much about the temps, the batmans are quite capable and have some beefy cooling indeed! i recommend to first try and undervolt your core and cache, thatll give u lower temps at the same exact performance

your assumption is correct, the igpu is disabled, thus ure not able to use it at all, including quicksync functionality. there is also no re-enabling it, since its physically not connected to the display.

Yes he/she was banned, but signed up again under another name.

Not sure exactly what happened there.

 

Seems you are getting it mostly right but due to this sentence it seems that you misinterpret TDP with power consumption. Maybe i'm wrong

TDP-example: On one hand you can set the 91W-6600K to a TDP of 3 W and it will not "use" more than 3W and it will do so because it will throttle as hell. On the other hand you can set it to 150W and it will not be faster than before, because a normal clocked 6600K will not use more than 91W.

The problem is, with the non-K versions you can not increase TDP.

TDP is only a limit, a border or boundary. But a very useless one. Get rid of it, go K!

 

I can make this one thread for both the 15 and 17 inch models if that's what everyone wants

 

I don't think there's another thread going for the P77xDM

But it would be nice to make this one about both models: P75xDM and P77xDM.
I think everyone will more or less agree.

 

I changed it. I agree if there is little difference between models then it becomes a redundant hassle.

 

So I went through reviews for the 15" & 17" models on NBC

Clevo P751DM
Clevo P771DM

I find the surface/chassis temperature differences quite striking. The 751 was tested with the i5, the 771 with the i7, yet the 771 posted max load temps of almost 20C lower at certain spots on the chassis, and 10C on the keyboard.

I find it hard to believe a slightly wider chassis using the same motherboard and cooling system would produce results that different.

 

Rule #1 of life my fried - There's no such thing as a free lunch.

Smaller chassis will always run hotter. There's less material to help dissipate the heat further than the heatsinks.
High temperature components like the CPU and GPU will also be farther away from less heat generating components like hdds or ssds meaning a slightly cooler airflow and surroundings.
Also, in the 15 incher, your hands are right above the CPU and GPU and you'll feel it more.

 

50 degrees Fahrenheit is a lot more than feeling it... The center of the keyboard got to 118F!

 

@Ramzay - just an FYI both the links in your post go to the XMG U506 / P751DM review

Quoted from the review: "Low noise emissions do have its drawbacks; generally, the low fan speed means worse heat management, as is the case here."

These load temperatures are with Prime and Furmark running, with the fans on AUTO and not set to Fn1 100% as they should be. There will be a lot more heat build up with this much load and with the fans on auto - which will account for most of the difference. Set the fans correctly according to the extreme load that they are putting on the system and the temperatures will be lower and likely closer to each other.

 

I think review is 100% correct here. Clevo made a compromise limiting the max auto fan speed for lower noise on high speed. Whether its justifiable (because such loads are not normal) maybe debated, but the compromise is here.
Plenty (or should I say, most?) of laptops out there that do not require to press buttons manually or fiddle with profiles just to get cooling system to function at full capacity.

 

Thanks, fixed that.

 

In this case though, they aren't further away. Both models use the same motherboard, and the SSD/RAM etc. are all pretty much exactly the same distance as they are on the 15" model.

If it were a completely diferent motherboard and cooling system, I could see why the temperatures were so different. But in this case, the CPU/GPU are exactly the same distance from each other (and the other components) in both laptops. The extra width of the laptop is largely wasted on nothing - have a look at photos of the laptops with the bottom panel off. Clevo essentially put a block of some type of plastic to the side of the GPU fan.

You'll find pictures in the following reviews by HTWingnut

@XMG @Ingvarr

I think you're both completely missing the point. Both machines have the same cooling system, mostly the same layout, and the 771 even has a more powerful CPU. Yet the temperature differential between the two at load (in terms of chassis/surface heat) can be as much as 20C. In other words, the 750 chassis in spots can be 20C hotter than the 771.

I'm not complaining about the CPU/GPU temps, or fan noise, or whatever. Just commenting on the temperature difference between two almost identical machines (especially since the extra width on the 771 wasn't used to move components further away from each other, or add larger heatsinks/fans, or add heatpipes, etc.).

I really don't know why you're defending certain aspects of the cooling system - I didn't comment on that. Your comments seem to be in response to somebody saying "OMG why is this machine running so hot" - except I didn't make such a comment. I'm asking why one is so much hotter than the other (almost identical) machine.

 

Apart from not looping a benchmark (no-one should ever use Furmark) those reviews also missed to make use of the FAN features of Clevo's Hot Key App.

In DM systems it offers these FAN features:

- automatic
- maximum
- overclock (adds xx% to the usual speed - allowing it to reach 100% automatically)
- custom (allows alteration of minimum and maximum values)

 

I am not defending it. And differences in heatsink performance are well known since ZM series - because Clevo design of combined rigid heatsink for two chips does not allow consistent contact point unless you fiddle with spacers/lapping a lot.

(btw, I find notion of "program you must never run or it will destroy your hardware" is ridiculous and simply promoted by manufacturers unable to meet fully required TDP envelopes. CPU/GPU must be able to handle whatever load you throw at it, period. Maybe not on full theoretical performance, but without damage either.)

 

I'm sorry you're losing me.
I just ordered a P771DM-G to replace my MSI GS70. Too much heat and noise where dealbreakers for me in my experience with the GS70.
Are you saying this isn't any better? Are heat related issues to be expected?

 

Just adjust the fan curve. Problem solved. I wish my P377SM-A had that feature instead of auto or max.

 

You choose:

Lower performance in all the applications you actually use, survives power virus.
Higher performance in all the applications you actually use, don't run power virus applications over extended periods of time.

 

Clevo has always had auto fans never hit 100%. Even as far back as my D900F in 2009, I needed FN + 1 for it. It's not difficult, and it's an integral part of fan control of the system, and works in the BIOS (hotkey app is not required). What you're saying is that Clevo should have had the fans hit 100% on auto... and I'm not going to disagree. But it's a far cry from being some sort of design FLAW.

Yes, most of them do. Legacy Alienwares require fiddling with custom fan curves in HWiNFO64 for best cooling. MSI has a fan curve app that is necessary to use for best cooling potential. Who's left? Razer and Gigabyte and ASUS? Lenovo cuts out turbo boost from the system when CPU and GPU are both stressed instead of using a good enough cooling system. I think manual fan curve adjustments is not a bad thing.

The differences in heatsink performance is because who Clevo buys from does not make the heatsinks proper to form. The DESIGN is fine. The actual batches of heatsinks are not fully true to the design, and thus can falter. THIS is something they need to improve on, and thanks to Prema and his connections, it looks like they will be doing so in the near future.

Furmark in itself is a GPU power virus. Limiters have been placed on hardware to prevent damage from it, but it doesn't mean it should be run anyway. It is what it is. It's not meant to "test".

 

Often those limits mean a game test can actually be more stressful anyway.

 

The ability to go max fans is something that attracted me to Clevo laptops in the first place. Coming from the Dell M1730, Alienware M17x, and my current Asus G73jw, I'm not used to having such basic control over the machine

 

Huh? Why are you comparing an MSI to a Clevo?

At what point did we mention the MSI? I was comparing the 771 to the 751.

Im pretty sure the 771 is much quieter and cooler than the MSI GS70.

 

I mentioned the MSI.

It's just that those differences between the 771 and 751 might be due to the heatsink and possible bad contacts with the CPU and GPU. Resulting in some units with adequate and efficient cooling while others will throttle and heat up considerably more.

I'm sorry, I had a really bad experience with a Clevo notebook some years ago. Now I'm going back to the brand thinking they have changed and quality control would be better. Hearing about these issues is making me uneasy about my purchase.

 

Clevo really does need more consistent heatsinks... Foxconn sends out so many warped heatsinks its not even funny.

 

I didnt notice but sorry if I sound overly worried over the heat and wattage but reading the discussions are helping and I'm learning alot thanks to all you folks . I look forward to get my machine even if its the non k cpu since there already much stronger than what I have now. And now I learned about the max fan buttons which I can customize. I'm really excited over this and by middle October I should be all set with a batman.

@ about the NBC review I'm surprised the 17in has more battery life at idle especially with the bigger screen? I first thought they rushed the 15inch review since the battery test had less results but looking at it I think they were done right however I wish they also tested the wifi usage and movie loop like they did in the 17 in dm but but I could be wrong and I do understand that the machines are basically the same and the reviews were helpful to me.

And how would one know if they have a bad heatsink and is that covered in the standard 1y warranty?

 

I agree completely. I don't think any reviews should use Alt-F1 because most users are never going to use (or even know about) that fan mode. If the notebook needs to go to full speed fans to adequately cool, it should do so.

 

That's the problem. You would have to take the heatsink off and get some pressure sensitive paper like Sensor Products Ultra Low and then remount the heatsink and look at the impression. Ideally it would be almost completely pinkish red across the spread of the die. Quite often two corners and the center are not flat.

Trying to get a new heatsink using the warranty wouldn't work unless your temps were too high. You would have to lap the heatsink yourself to make it flat. I had a heatsink warped so badly on my P377SM-A that I couldn't use Liquid Ultra because there wasn't enough contact between the die and the heatsink. From what I've seen, they have improved but I can say from my personal experience that they can be pretty bad. Again though, if its not causing a thermal throttle its nothing to worry about, it just leaves potential for modders who want to push things further.

It isn't just a Clevo problem either. Heatsinks across both laptops and desktops have a tendency to not be as flat as they could be which is why lapping the heatsink became a thing but with Haswell it was extremely problematic because of the sheer heat that needed to be dissipated.

 

Where do you get these sensitive pressure films? It's nearly impossible! Only offer I saw was via Amazon for about 500 bucks....

 

They offer a free sample here... Not sure how the whole thing works. https://www.sensorprod.com/samplerequest.php?Prescale#

 

Nvidia have released a new driver,358.50. However I still can not install it on my 751DM-G. And I need someone else to confirm that DX12 is not working with stock driver.. (just go to dxdiag and it reports 11.3)

 

please define "cannot install driver". what exactly happens?

also, have u downloaded the mobile or desktop driver? the latter wont install, unless modded and with driver signature enforcement disabled in win8.1/10

The 980m used in 7xxdm-g uses a new hardware id that is not in the current driver inf. The driver installer just reports "Can not find compatible hardware".
Modded inf with latest drivers works well and enables DX12 support.

 

Did you mod the driver by using the inf file from laptopvideo2go, or did you mod it manually? If the latter, what did you do exactly, as I seem to have a similar issue. Thanks!


Edit: Okay! Found some guides how to do it manually. Will give it a try!

 

good info@hyno111 generally, laptopvideo2go covers pretty much all hardware IDs, so it would be a good starting point for modded drivers

 

Manually.
Basically its like this
1) Open nvcv.inf in stock driver

2) Find the line with your hardware id, for me its
%NVIDIA_DEV.1617.7503.1558% = Section034, PCI\VEN_10DE&DEV_1617&SUBSYS_75031558
You can check your hardware id in device manager.
and go to the last part of the file, find the name for the card
NVIDIA_DEV.1617.7503.1558 = "NVIDIA GeForce GTX 980M "

3) Copy these lines to the corresponding two parts of the nvcvi.inf in the official driver, save.

4) Reboot to disable driver signature check

5) Install the driver via device manager, not sure about whether installer works.

6)Profit!

 

Sorry to break the conversation but, I was told that I will need to wait for the i7 6700 (non k) as there is global shortage. Anyone knows when stock is generally available?

 

Weird, I can find it in stock pretty easily here in Portugal. Many stores have it available...



Anyone know of new reviews about the P75xDM or P77xDM?

 

I understood from your post that you were talking about the differences in temperatures between the two systems rather than specifically high temperatures, however any explination of this must include how the fans were set up in each system. One of my points was that if the fans were set correctly/as intended (or if they were running at 100% through an automatic fan profile) then you would see

Ultimately we don't know if they were tested under different conditions or if there were other factors. For example, the two reviews were written by different people and we have seen in the past that different notebookcheck reviewers have made different conclusions and testing results.

I don't disagre with this at all. In the case of the P7xxDM models, if the fans are set as Prema explained then there is no throttling at stock. We have only seen throttling in the notebookcheck reviews because they ran the most demanding applications with the cooling system running at under 80% efficiency.

 

How about on-die watercooling for the 6700K?

 

We just have to wait for someone to create that for the DM

 

Hello, first time Clevo owner here, P770DM-G (couple SM951's, 6700K, 64GB) from lpc-digital; Larry was *awesome* to work with!! Just wanted to drop a line, say hi from the new system, just finished configuring mint 17.2, kernel 4.2.3, nvidia and wireless drivers without any hiccups whatsoever, have spun up over 13 docker containers running a variety of things along with 4 VMs and the machine is just blazing through it like it was nothing. I can't say enough, just thoroughly and completely blown away.

Basically I feel like this guy:

http://static.hometheaterforum.com/imgrepo/6/62/htf_imgcache_8556.jpeg

 

notebookcheck test have purpose to show how cooling system behaves under 100% load *by default*.
To see if it throttles or makes it too noisy, or overheats, or whatever else. This simply because they don't just test temperature, but also noise levels and such - and trying to additionally evaluate all possible options of tweaks/manual controls tested would not make easy to understand/comparable results (they need some benchmark that is same across different notebooks).

But they probably also should mention that (if) manual control is possible - but remember that then they will also measure that, for example, noise goes through the roof too

 

So I just got the laptop today, all fine and dandy except the Intel 8260 is not seeing any 2.4ghz wireless networks; just the 5ghz ones. Any tips? Using latest drivers from intel and also tried with the ones from clevo.

The laptop configuration is:
i5 6500
980m
16gb HyperX Impact 2400mhz
850 evo ssd 500gb.
