1) Yes, unless you enjoy your CPU reaching 90+C at stock clocks. At least go for the delidding option. Only HIDevolution offers CPU Delidding from the factory. If you delid yourself, say bye bye to your CPU warranty

2) The 3K Screen is the best screen I've had on any laptop, see my review here:

EVOC P870DM3 Review by Phoenix

 

Lottery not necessary but do get the delid option. It helps with temps. the 3k screen is freaking awesome in my opinion.

 

I agree on the 3K screen, I enjoy it as well and I agree on the Delid. I did the delid myself but as he said the warranty is out the door.

 

Yeah I forgot to add I always assumed to take at least the delid. Does the CPU go above 90 with delid still? I also had the P775DM3 chassis that unfortunately had to be refunded (105 max recorded CPU core temp) and it sounded like a leaf blower.. Like 90% of the time it just unleashed.

Does the P870DM3 also become so incredibly loud? I understand a laptop needs to cool itself but damn that thing was extreme...

Thanks for all of your replies!

 

Spoiler: With "Full Fan" run...06:54

 

You will have to get separate opinions on noise. This is one of my first gaming laptops and even with the delid I still run it with the fans going pretty loud (just my opinion -subjective) in order to keep it cool; however, with my headphones on I don't hear them. With the fans running low it still gets up to around 90C for me atleast but with the fans running fast and a bit of a undervolt on the cpu I run in the high 60's for the CPU and GPU. I have not really found a happy medium yet, it is either run the fans almost at full and get great temps or run them low and get high temps. If you haven't looked at the review in the link below you should and you can see the fan noise in one of the vidoes.

lol this is brilliant.. and sadly seems like the P870 chassis is just as loud as the P775 which honestly is a no go for me... It's not that it's annoying or unpleasant, It's just kind of disturbing to have the laptop (and honestly the whole desk) vibrate from the jet engine cooling.

Do you guys know about the 15" P751? I'd be willing to trade some power for portability and less noise + it's so much cheaper

 

I have no clue but would assume with any 1070 or 1080 setup the laptops will probably have loud fans.

 

I haven't seen a quiet gaming laptop in recent times. Any laptop with pascal I've dealt with or played with to date is fairly loud. I use headphones when gaming on my laptop anyway. I did drop my clocks down to 4.2 from 4.4 and dropped the voltage to -125. It did make it quieter and the CPU maxed out at 62 and the GPU's in the mid 60's as well in bf1. I'm sure once @Prema magic comes out things will get even better.

 

WTWingnut's video was from an early Sager build from August. Much has been improved since then, and delidding and under volting with the Prema BIOS will help even more with thermal control, which helps keep the noise down. Our temperatures are much lower than what he shows there. Vibrating the whole desk from the jet engine cooling is an exaggeration of today's reality.

I do understand that it would be nice to have all that horsepower, and have it be quiet too, but moving air simply makes noise...you can't have both.

.

 

Could we Sager users flash that Prema BIOS? People say that if Sager laptops flash a third-party BIOS, warranty is void and may even brick if we try to flash it back.

 

Yes, if you somehow had access to it.

 

Guys... I just noticed a really bizarre issue.
The Movies & TV app, built into Windows 10, stutters when in fullscreen mode, and exclusively after the status bar disappeared. All the other players work flawlessly! Even windows media player!
I made a video demonstrating the issue:


Any help would be much appreciated!
I post here because I want to make sure it's not hardware related...

 

I think the noise is worth it though. With a single GTX 1080 averaging 102 fps at stock settings in BF1 with a 3k monitor. Doesn't get much better than that for a laptop!!

 

As a comparison if any of you all are playing BF 1 with sli GTX 1080 what is your average FPS at 3k?

 

@afloyd Guess you got the better processor. Looks like at stock voltage I can run 4.5 but at -50 I cant run 4.5. Lol, I had to edit this like 3 times. Guess I have had to much to drink!!

 

cranked up to 4.2ghz, the cpu got up at 80C..
http://www.3dmark.com/3dm/16434609?

 

I set mine to 90mhz / max graphics and once the headphones go on I am in a different world of epic battles. Usually hover about 80 c long term.

I have the p870dm2 with a 1070. It has a Windows 10 installation in UEFI mode on a NVMe SSD. I want to dual boot Linux Mint, but cannot get the live USB to boot unless I turn off UEFI. Am I doing something wrong, or do these only boot Linux in Legacy BIOS mode? Any help would be greatly appreciated.

 

Can anyone for comparison post YouTube video about how loud is p870dm3-g with 1x1080 or 1x1070 ? Of course with temps itd. I'm talking about this laptop with few resellers in my country and final decision will be made soon. Don't want to pay for bga trash :/ I'm interested in low temps in games like witcher and bf1 . Someone posted here that he have 60c gpu/cpu after long gaming sessions , it's Rly greate news.

 

60C after long gaming sessions? 1080 in a laptop? Minesweeper maybe.
I always hit 90C as it's the temperature target, the difference is how fast the fan would spin.

 

5 mins stress test using AIDA64 . Overclocking fan profile, they're not so loud to me for such high clocks speeds. Running a 4.6GHz overclock 24/7 on my Silicon Lottery delidded CPU:

 

Incredible. Mine will hit 95C even undervolted by 120mV, and running at 4.2GHz... I've already redone the thermal paste, so maybe something else's wrong?

 

First system I had was a barebone Clevo P870DM-G with a 6700K that couldn't even run stable at 4.2 GHz x4 (on all cores that is). Next system which was a Eurocom Sky X9 also had a 6700K, this time a bit better, it was able to do 4.3 GHz stable.

I have seen many users here complain about high temps even at stock speeds. The 6700K is a hit or miss, 50-50 chance to get a good one. Even if you don't want to overclock, spending a bit more to get a Silicon Lottery one ensures your CPU will run cooler overclocked or not. Giving you better thermals and longevity since the CPU won't be running hot constantly.

This Silicon Lottery CPU I got (rated to run @4.8GHz in a desktop) can run @ 4.6 GHz stable all day long with max temps of 82-85C no matter what I throw at it.

Other than pasting with the X Cross method, if that doesn't solve the issue, then you weren't very lucky with your CPU, just like 50% of the users who complain about heat issues.





Also, for 4.2 GHz, you can go for a -150mV undervolt but you have to do it in the Prema BIOS so you can alsos apply the undervolt for the Cache Ratio as the CCC doesn't have control over the voltage for the Cache. Otherwise, you can use ThrottleStop to undervolt the cache as well if you don't have the Prema BIOS

Lemme post my settings for you

 

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

 

Well, seems that I lost the silicon lottery indeed. I did my thermal compound (IC Diamond) with X method but didn't make a difference.
This is how the temperature looks like:
The CPU won't throttle, but it does go up to 96C, and that's even undervolted by 120mV. Maybe I should try 140mV now.

 

I can't see the image, please don't use the forum's built in image uploader

Also, -150mV is totally fine for 4.2 GHz on all cores. Try that

Finally, I wouldn't accept a CPU that reaches 96C on stock speeds. that is not healthy for the longevity of the CPU man.

 

Already done the undervolt, doing stress test.
I'm a little bit concerned about using ThrottleStop, as I recall it's not been updated since like 2013? Won't that cause issues with newer architecture?

 

I would check the contact pattern of the heatsink.

 

v8,35 is what I'm using, it's updated on a mothly basis man

latest stable version is 8.30 = https://www.sendspace.com/file/ghbhyh

unclewebb sent me the 8.35 version privately though

 

No luck buddy, even undervolted by 150mV, if I unlock power limit, it will start to throttle in 10 seconds. Temperature rise up to 96C, again.
Personally, after limiting the power to 75W, it won't throttle anymore, but the 4.2G clock speed is not so stable also.
Probably just a poor chip...

 

is there any chance to replace it under warranty?

Remove the undervolt then show support how high the temps are, it would be very hot even more than 93C tell them this is one overheating chip despite the repaste

 

I've already tried that when I first got the notebook, they told me to run Intel CPU diagnostic tool, and at stock settings it reported no problem, then they refused to change it.
So.. it's all about silicon lottery after all?

 

That CPU Diagnnostic Tool is a stress test? If it's not, then it's not a proper indicator to show if the CPU is overheating.

It is about the Silicon Lottery after all. If you have the cache, buy a Silicon Lottery CPU and sell your current 6700K to any desktop user In a desktop with better cooling, it will run better for that guy anyway

 

It's an official tool from Intel, it's mainly a functional test but it does contain a short period of stress test. However, that stress test is far less harsh than AIDA64, and from the description its criteria is whether the CPU hits TJmax, which is 100C. I highly doubt any working CPU will fail that test.

I hate my life... I thought everyone has the same problem, finds out it's just me. T_T

 

it's not just you man, I cannot count the number of people I've helped undervolt their CPU by -150mV to tame the temps. it worked fine with max temps of 85C but nothing higher than 4.2GHz. Yours is the worst of them unfortunately. Sorry to be the bearer of bad news. But on a positive note, it's super easy to swap the CPU and sell yours. It ain't the end of the world. Don't take another chance and get a Silicon Lottery one

See: https://siliconlottery.com/collections/frontpage/products/6700k48g

If you do order it, choose the delidding option as well to make it even cooler

 

@Phoenix So you run 46x4 CPU, and 41x cache at same voltage? Why not also run the cache at 46x, or run it at 41x with even lower offset?

 

no I'm running the cache @ 4.4 GHz now. Anything higher produces a lot of extra heat at no real performance gain.

I don't like running the Cache with a different voltage than the CPU. On my previous P870DM when I did that, I would get crackling from the speakers

but let me try setting the cache to 4.6 GHz now and see what happens

 

@afloyd

I tried setting it to 4.6 GHz and the moment I reached the Windows desktop, the system crashed.

Now I set it to +20mV for the CPU/Cache overvolt (not undervolt) =



Temps are a bit high for my liking. now I'll try stock voltage......

 

Ahh interesting... Didn't realize there wasn't much of a performance benefit increasing the cache rate. I'm running 47x5 (CPU/Cache) all the time, and when benching I always try to match cache with CPU. I'll have to try some testing when I get time on some benching and see if dropping the cache might help with the throttling since it may not be helping performance much!

 

see: http://www.tomshardware.com/answers/id-2475409/overclocking-cpu-cache.html

 

@afloyd

ok at stock voltage with no offsets it's better. CPU/Ring @ 4.6 GHz

 

Here was mine cpu/ring at 46x 0mV offset... Not sure why but shortly after the test started it did briefly bump the multipliers to 44x, but you can see from the averages that it pretty much stayed at 46x. Max temps were 83*C.

I do have it sitting on my laptop cooler pad (because it's sitting in my lap), but it's just a cheapo powered by USB from the laptop

 

that throttling will be fixed soon once you get the Prema BIOS as it's not thermal throttling. Once you have the Prema BIOS. I'll guide you how to max out the power limits and VR Current limits to prevent throttling, oh, and the Turbo Power Max and Turbo Short Power Max as well

is that a silicon lottery CPU? that temps are great

 

@afloyd

A lot of users are having problems with that G.Skill RAM. I am not because I have the first batch which was great, the new batches are very bad. What XMP profile are you running on and do you have any issues?

 

I guess I must've gotten in the lucky early batch with you... I haven't had any problems on XMP1, I've posted a few tests over in the Overclocker's Thread. Ran 47x multipliers on wPrime & TM5 without any issues!

Ya personally going from a 1080p to a 3k monitor was a pretty epic improvement. Loving it!!

 

Will the Prema BIOS make the Bus Clock stable as well? I noticed mine seems to bounce a lot and rarely stays at 100MHz....

Nope, not silicon lottery... Just got the premium delid/paste by HIDevolution. I just got really lucky in the mass market lottery, or HIDevolution just happened to give me a SL one, haha!

 

you can bump the BCLK in the Prema BIOS to stabilize the clock speeds so they don't show you like 4.69Ghz but a steady 4.7GHz

 

I bought some corsair vengeance from a friend who was getting rid of them cheap 4x8 (32 gb) -100 dollars. Couldn't pass it up and wanted to try them out. If they don't work out good ill just sell them. I see that a few of you have the 16x2 module. The stock settings are 2666 (18,19,19,39) which runs just fine. XMP 1 shows 3000 (16,18,18, 39) but is not stable with 4 modules. Any suggestions on overclocking these from anyone who has had experience with them?
