Check what the temps were before the game and then after the game is closed. The curves are a bit on the aggressive side .

 

just did a test, in game my speeds were near max and then after about 5 minutes of the fans still being around 50% my temps were sitting at the idle temps 58C for the gpu and around 45C on the cpu. The one thing that fixes them is restarting my PC and that puts them back at normal speeds

 

Putting the fan speed offset to 0% and hitting apply puts it back at what it should be but im basically having to do that every time I get off of a game. Even then i feel like they are higher than what they should be. Im just curious as to why the automatic mode is so damn loud.

 

So I just saw the following review of kaby lake edition of GT83. It couldn't even keep up with skylake gen DM3 model at stock (not a surprise really). But what is surprising is that the total package weight of GT83 is actually more than that of KM and DM models, and the price differential is bordering on ridiculous (even more so in Blighty). And what were MSI thinking with offering only one year warranty?



On a side note, I'd imagine MSI can fit in a Z270 series board in that chassis and deck it out with dual 1080 cards. Why aren't they doing that? It is not like they are offering any of that coveted weight saving with their BGA GT83!

 

It's selling so why pay the price of development without so much help from Intel?

 

I doubt there will be a discount that can offset a $200 price increase, lol. Either way, I am curious to learn more about the mobile TDP limitations, if you have any sources. From what I can see, they don't list a TDP for the mobile cards, as they seem to vary per manufacturer. One thing is for certain, I've seen a mobile 1070 on 3dmark clocked at 2100, and it was "powered by premamod" on a P870DM-G. Would be nice to know what sort of sorcery this man used to achieve such a clock speed. Perhaps he has access to a custom vBIOS that we do not know about?

EDIT: Would probably help make my post more credible if I link that 3dmark result: http://www.3dmark.com/fs/11661315

 

The speed there doesn't matter. It probably pinged the highest speed and stuck it. I mean I could run a test and it'll show 1860MHz and my speed could drop to 1793MHz during the heavier tests and it wouldn't show. You have no way of knowing. I'll get a run for you from a system that'll throttle later. I can't get one now, but I will get it soon, and come back and report.

 

GT83VR has its own benefit, larger display, mechanical keyboard, better cooling system due to larger radiator area, better audio system. p870km1 is more portable, more powerful cpu, better value in terms of cost, non soldered cpu. if only i know right now that 870km can fit the upcoming 6c coffeelake i'd pull the trigger right now but too bad i wont know how intel will try to m!lk yet again and force another upgrade to new chipset.

 

Then how do we explain the score he got? Here is my 2050mhz GTX 1070 (it boosted to 2076, which is why it shows that) http://www.3dmark.com/fs/11737844. Notice how the graphics score is 20502. Believe me when I say my card can hold 2000mhz+. At worst during runs, it drops to 2025 (two boost steppings below actual clock) but the score is still what it is. Now look at his, which scored 21804: http://www.3dmark.com/fs/11661315. We already know that the GTX 1070n has 6.7% more cuda cores. Assuming linear scaling (I know, not everything scales linearly, but bear with me) we get a number of 21,875.6 if we add 6.7% to my 2050mhz 3dmark score. That is just 75 more points than what he scored, at his supposed 2100mhz speed. I have no doubt that he throttled well below that number, but I am willing to wager that he was still going higher than 2000mhz during the entire duration of his run. Otherwise, the numbers wouldn't add up.

Here is the link to the guy in question: http://hwbot.org/submission/3452498...e_geforce_gtx_1070_(notebook_mxm)_17921_marks. If you look through the other MXM rankings on HWbot, you can see that he isn't the only one going beyond 2000mhz either, and their graphics scores add up too.

 

Maybe rather ask @Coolane himself ?

 

I was unaware he was a member of these forums. Thank you for showing me. @Coolane If you don't mind me asking, did you do any shenanigans to make that GTX 1070n of yours hit 2000mhz+, or was it capable of doing so "out of the box"? Your scores are really impressive, and even beats my aftermarket desktop 1070.

 

You could find the info with Google Search

 

You could also be less passive aggressive over small things, but we all have our faults. I'll take that into consideration next time.

 

It was not meant as a case - offense. Sorry if you took it this way

 

No worries, I was more concerned that I angered you by not using Google to see if someone was on this forum. Either way, I am very interested in knowing if he is using a custom vBIOS or if he has a custom MXM that can natively handle higher clocks. I am still new to laptops, so I don't know if such a thing exists.

 

Check it out. Props to @John@OBSIDIAN-PC and Ricardo for contributing the basic info to point me in the right direction, and some encouragement to try it out. Kudos to @Ted@HIDevolution and @Donald@HIDevolution for sending the guinea pig heat sink. Once I get my Bitspower IHS I will be sending the modded heat sink back to HIDevolution for more validation.



For @Papusan

 

Hi, @MageTank
I did do something on the 1070n.
Here are the things that I did:
1. Cooling mod, lower the temp as much as possible. The 21804 graphic score was run with 41F environment temp. The GPU core temp during the run was only about 20C.
2. The card was unlocked to 200W. (please don't ask me how I did this)
3. The vram was highly overclocked to about 9600 MHz.
4. OS was optimized with minimal background tasks.

 

I'm very tempted to do exactly that!

Do you want me to do that for you before shipping your unit?
Muhahaha

 

Pretty please! And I promise to send along some white chocolate for you along side the dark variety for Ricardo!

 

1. Do you have a link to this cooling mod? If not, I can try searching through some of your threads.
2. I assume this was done with a custom vBIOS, which simply answers my question of "can this be done out of the box" with a "no".
3. I assume you had Samsung IC's on the card? Our Micron IC's on desktop cards don't clock well at all. +400 AFTER the Micron vBIOS update and that's still skirting instability on my desktop 1070.
4. I already shave my Windows installs down when benching, so I understand this.

 

Here you go: http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-1046#post-10476134
Yes, I have Samsung chips on my card. 9600 MHz was only benchable under very low temp. For everyday use without artifact, it's about 8800 MHz.

 

That is a ton of heatpipes. Far beyond the effort I am willing to put into making a laptop run cooler, lol. I'll stick to the classic undervolting/underclocking to improve my thermals, and focus on building a long-lasting machine. Bleeding-edge performance isn't my goal, as I have no intentions on replacing my desktop. I simply want a laptop that will do my games at a decent refresh rate, with G-Sync, without it becoming useless after a year or so. I personally believe the GTX 1070 will be plenty fast enough for my moderate expectations. Now I simply need to wait for the next paycheck, and to give @Donald@HIDevolution another call.

 

well, I did tell you that it was abnormal... though I did not expect a hard power mod for the card and such extreme temperatures.

I still very much suggest a 1080N. It may be small but are you getting your NBR discount? And I believe there may be a cash discount like most other vendors do? See if it adds up to allow for a 1080N and that vapor chamber

Or ask about... is it financing?

 

I've yet to ask about the discount, so I don't know the exact figure of it. I also doubt I can do financing, as I have zero credit. Again, I am more concerned about thermals at this point, with performance taking a backseat. I understand that the 1070 will be slower, and that regard it won't last as long as a 1080 from a performance standpoint, but from a longevity standpoint, it should have the potential to last a little longer assuming I can keep it cooler. G-Sync should also pick up some of the slack in the more demanding titles. With this being a 1440p panel on a 17.3 inch screen, it's unlikely that I'll need any form of AA, so I expect that to also shave a little bit off the demand for higher end graphics solutions.

My budget is already $500 over my initial budget of $2000, so I have to be strict at $2500. This is not even counting the fact that I won't be getting a CPU from HID, and will be using my own. It only makes the cost higher in my eyes, once I factor in the $300 I paid for my 7700k.

 

lol you think so huh

If you're not getting a CPU from HID, then there really is no point getting this system. You *NEED* it delidded. I cannot stress this enough. Buying it yourself is not going to be pretty.

You can get a P775DM3 with 1440p 120Hz gsync, 1070N, 7700K, 256GB 850 Pro, 1TB 7200RPM HDD, 16GB 2400MHz RAM, and the intel 8265ac card from them for about $2526. The NBR discount should make it basically an even $2500, which is your budget limit, with what I assume to be everything you want. With the work they'll do, the cooling will be fine for that system. It won't be as overkill as 1070N/VC/7700K in the KM1, but I just can't tell you that what you're doing is a great choice. As much as the P775DM3 is an unpopular choice here, if you're going to spend $2800 for this thing and not even get the delid done, it's just wasting money. Your temps will be impossible to control. Before I delidded this thing using max fans single GPU just on Final Fantasy X HD (a 1080p 30fps title) I would hit 90c on the CPU at stock.

 

I've been delidding my own CPU's since Haswell first released, lol. I am currently using both a delidded 6700k and 7700k, both having CLU on the bare die. My 7700k is binned at 5.3ghz, and does 4.7ghz at 1.11v stable (assuming laptop doesn't sag as much, and has decent VRM). I also plan on underclocking/undervolting below that. I appreciate that you are concerned for users choices, but I am certain that I have the CPU aspect completely covered. Years of using ITX desktops has taught me that exotic solutions are the only way to go if you refuse to compromise on performance within a small form factor. I only wanted the P870KM because I was told it's cooling is far superior than the P775. If that is true, then I would rather spend the extra money on the P870KM for that factor alone.

 

Ok, fair enough. The P870KM1 vapor chamber single GPU cooling is most certainly the best non-liquid-cooling I've ever heard of or seen in a notebook. I legitimately cannot make it overheat. The CPU side of things needs work, certainly. I have been checking my system's temperatures against @Mobius 1's KM1 with his adjusted pads, and there's easily a solid 10c+ difference between us, and I *STILL* am 100% incapable of getting a single 1080N to hit 70c in this notebook in any scenario I have tried. The highest I have seen was 68c on an extremely hot (34c+, high humidity, stagnant airflow) day, and that was still about 2 weeks into using it without a cleaning out, so it wasn't even "fresh". The CPU will offload some heat onto the GPU side of things, and hotter GPUs definitely make the CPU hotter, so single GPU remaining cool automatically means a cooler CPU by default by this design.

If you have the chip and have delidded it already, you might be able to send it to them for installation so you get the machine working already, if that suits your fancy.

 

I have a 1070 in my rig, It was a huge mistake. If at all possible get the 1080

 

A mistake in what regard? That it was not powerful enough?

 

Yes, need more power. However, I'm not a gamer, actually have never played a computer game. I use my computer to do Design work, Architectural type remodeling designs. With the programs I use,(designs, estimating software etc.) I've had some minor issues that guys with the 1080 have not.

 

The other reason is upgrading to the 1080 when you order is about $400.00, purchasing it after the fact is about $1200.00

 

Don't forget the 1070 can be sold to help offset the cost of the 1080.

 

The shape does hurt the potential market however as to who can fit it.

 

I can't imagine the 1080 having that much more power though, unless it's able to hit 2000mhz without the Prema vBIOS. We are talking a difference of exactly 25% cuda cores. Assuming clock speeds are identical, you'd only see about a 25% improvement in performance if we assume perfect linear scaling, which is almost never the case. The only way I can see it mattering, is if the 1070 is crippled by it's default power limit, and the 1080 is not crippled by it's default power limit. That could sway the argument. That being said... if the 1070n did get Prema's vBIOS, and could overclock, it would also bridge that gap as well. I suppose if you use this laptop for more serious purposes, the extra horsepower would be appreciated. I personally use a 940m in my current laptop, so trust me when I say that I can make a 1070 last forever, lol.

 

1070N is 115W limited.

1080N is 190W limited.

 

What kinds of clock speeds have people been hitting on the non-Prema/Svet 1080's?

 

I haven't seen a power limit drop below 1835MHz at stock. Probably could get more out of it if the cards were cooler (more heat = more power drawn, if slightly) and if I adjust voltage curve via MSI Afterburner, but I'm not disappointed in my speeds enough yet. It still does better than a 1080 Scammer's Edition desktop card.

As for overclocking and holding the clocks, you'll have to ask some of the people that overclock and game like @bloodhawk

 

I can get 2Ghz out of my 1080s in gaming.

 

Tops i have been able to do on my 1080's on TOP of an AC is about 2062Mhz. That too briefly, because of the power limits.
Though with the way Pascal works is that it will drop voltage/clocks to keep you under the TDP. Add to that the temp throttling. So technically the power used will drop based on how far the clocks are drop because of the temps/tdp.

For games it hovers around 1984-2012 Mhz depending on the game and the temperatures.

 

Is this without a custom vBIOS? If so, that might be a considerable difference in performance. Seeing as most of these locked 1070's seem to be stopping between 1700-1800. A 25% difference in core count on top of a 10-20% difference in clock speeds is sure to yield a sizable difference in performance. I'll talk to @Donald@HIDevolution on one of my days off, to see if he has any recommendations. I already know he prefers the 16L13, but it's lack of 120hz G-Sync is just too off-putting for my needs. It's price and size is amazing though, just a shame about it's G-Sync support.

 

There's no publicly available custom vBIOS for mobile cards, as far as I can tell. This should all be stock (though as you heard a couple users could remove power limits with a hard mod), but the 1080N and 1070N differences are that large.

Do note: the 1080N in the 16L13 is only 150W, and will not be capable of achieving the performance of the 1080N in the Clevos. I have checked with some users already. For the purpose of extended stress and gaming, it's similarly (but not as bad I think) limited like the 1070Ns are.

 

If you're running a 940m now, I'm sure the 1070 will be a HUGE improvement. My rig with the 1070 came from the factory with the 6 pipe heat sink, It kept it cool easily. I don't know if there will be a Prema vbios for the 1070.

 

I would not mind having the 1080n, and in fact, it would actually be an upgrade over what I currently have on my desktop, but I just don't know if I can justify compromising on the thermals to make it happen. The only way I can afford the 1080n, is to forego the VC, use every discount that may be available, and even then, it will be on the bleeding edge of my budget. Either that, or go with the P775 and trade heavily on thermals for that performance. While the performance boost from the 1080 is likely going to be substantial after seeing your guys point of view, it would be contradictory to my main goal, which is longevity. While I know mobile components are rated for higher heat, I still want the best thermals I can possibly get. My goal is sub 70C GPU and CPU temperatures at all times under gaming load (sub 80C in synth's if possible). To achieve this, I plan on both underclocking and undervolting my CPU, while fine-tuning GPU voltage with afterburners voltage curve. I personally feel I will be happier with better thermals over better performance. I know that it's possible to get both, but the price premium is simply not in my budget. I am already pushing it paying $2500 on what I consider a "want" and not a need, so I can't possibly fathom going beyond that.

 

You won't need to underclock the CPU if you're getting the system from HID and you're claiming it's delidded and 4.7GHz at 1.11v

 

I don't know, the results I've seen on this forum would beg to differ. I still see people hitting 80c+ on their 4.7ghz CPU's at "similar" voltages. Granted, It's hard to tell from some of the screenshots whether or not people are using the 1070, the 1080, running SLI, or which cooler they are using. Far too many configurations to make a concrete statement on.

I wish I had a way to test both a GTX 1070 and GTX 1080 laptop so that I know for certain whether or not I need a 1080. The fact that my 2050mhz 1070 serves me just fine at 1440p on my desktop makes me believe a 1070n will do just fine. After all, the 1070n does have a slight 6.7% cuda core advantage to help slightly offset it's clock speed deficiency. Not only that, but the better pixel density means less AA is required, so that's another boon (1440p at 27 inches, vs 1440p at 17.3 on the laptop). I can't tell what's more difficult to process at the moment. People's abnormally high performance standards, or my abnormally high thermal standards, lol.

 

woah http://wccftech.com/intel-unveil-basin-falls-coffee-lake-skylake-x-asml-ryzen-16-core/
if rumors true then we will see coffeelake with z370 this yr in august? lmao 6c variants

@Papusan is it finally time to get a p870km with a 6c and mod that cpu heatsink?

 

I am informing you, that using single GPU with unlocked FPS in any game I've tried thus far, with max fanspeeds and no mods other than delidding my processor (no shim, no Liquid Metal between IHS and HS), with a -115mV on my 7700K at the stock 4.4GHz (about 1.12v to 1.15v fluctuating, averaging around 1.12v normally) I have not been capable of hitting 80c on my CPU or 70c on my GPU.

With your chip being so well done, 4.5GHz at 1v or so, with the shim mod and some liquid metal (maybe a ring of ICD or something to surround it) and the VC, you wouldn't need anything but max fans to achieve such cool temperatures.

I own essentially the same machine, and with two 1080s. I'm telling you that I can do it, you sure as hell can with one 1070.

 

I really appreciate you taking the time to give me this information, it really helps. I've noticed in your sig that you are using 3000mhz ram. Does the bios support that natively? Or do you have to do any shenanigans to make it work? I hear that Premamod is adding some memory overclocking features to the bios, but I can't really find any images/videos of the exact settings they offer. I am a memory overclocking enthusiast, with my ITX desktop currently running 3600 C14-14-14-28-2 memory (2x16GB Samsung B-Die, manually overclocked from 3200 C14-14-14-34-2) with extremely tight tertiary timings. I'd love to be able to tune laptop memory to a similar degree, but I don't really expect this to happen, even with Prema. Still, it certainly has to be better than the previous HP and Lenovo laptops I've had. Basically, can anyone confirm whether or not Premamod gives access to any tertiary timings?

Here is my Aida64 cachemem result on my current 6700k ITX box (my 7700k has weaker cache and IMC, won the lottery on core but lost on memory controller as it tops out at 3466 at the exact same settings):

 

Prema mod has timing adjustments for quite a few of them. I would say Prema mod is necessary to unlock proper RAM stability, and people have gotten 3200MHz to work. For some reason, *MY* RAM is not using XMP, even if I just change XMP back to the default speed (for the time being anyway). I have to do some more work on it but I need a relatively cool day to work on the system. I think I'll need to remove some sticks to try booting. Almost every other person who's tried it though just turns it on and it boots. Stock BIOS may take some more work though.

I think the stock BIOS gives access to more than primary timings though.

Here's a shot from the Prema mod:
