Generally offering a generation behind (regardless of the real difference) would tank sales.

 

Guess it will take long time so i ordered one with dual gtx 1080, but i have a question regarding the adapter. Should both adapters be always plugged in or can i use only one if i disabled the sli ??

 

Both plugged in

Re-paste 2.1 with Grizzly Conductonaut on CPU and GPU's with dried up old thermal pads. 6+ Hours of 7860x1440p gaming on Mirror's Edge Catalyst with fans set to "Full" when gaming and then fans set to "Overclock" while using desktop. Also 4th 1080P accessories screen enabled. This is really pushing the P870KM1-G. Please see bottom right hand corner of HWiNFO64 program on the top centre accessories screen for total uptime.

P.S: My 17w/mk AlphaCool Thermal pads have not come yet! AquaTuning are still waiting for them to be made apparently... #TheirTakingTheMickey

BIOS: Stock Clevo Bios
CPU Max Temp (4.5Ghz 7700K): 80c
Max CPU Power Package: 84.5 Watts
CPU Under-Volt: -70mv
GPU (1080 Stock) Master Max Temp: 81C
GPU (1080 Stock) Slave Max Temp: 75C
Samsung 960 M.2 SSD Max Temp: 80c
NVidia Driver: 384.76

 

@Stress Tech jelouse of ur temps. My CPU at 4.2 ghz /35% usage have from 60 to 68 C. Dam creazy. And i will have to wait like 1,5 Y to delid it coz of warranty. Curse u intel.

Another question. Do you used any tape or something else to prevent LM leakage at GPU-s? On gpu ur temps are also creazy low.

 

De-lidding makes crazy drops in temps. As for the liquid metal on the GPU's; I used @Mr. Fox foam barrier trick and kapton tape on all open naked circuits. You can view the video right here:
I also have a foam barrier on my CPU. Photos will be coming soon as I have received my 17w/mk thermal pads. I'm still tweaking and testing prep work you see.

Don't forget these (above) temps are from using 4x external monitors with 3x of them enabled at 7860x1440 on NVidia Surround. When I game on my laptops 1080P screen, I get 75c max on CPU (4.5Ghz) and 77c max on master and 72c on slave GPU with -77mv under-volt on the CPU. I think NVidia Surround eats my processing power to the max.

 

This is my old video using the laptops 1080P screen with new thermal pads. I think the thermal pads cool the overall chipset putting less stress on the GPU die temps. The GPU die has the temp sensor and the memory does not.
Go to the end of the video, On HWiNFO64 program you will see 2+ hour uptime and max temps. This was with new 17w/mk thermal pads and Grizzy Kryonaut. I think every time I pull my heatsink out; the more juice comes out of the thermal pads and now they are ruined. Also my laptop is on 6-18 hours a day. I let my brothers game on it too when they come to visit me. So its been ragged! lol

 

The official answer is always two, however if you were to run a stock CPU and GPU under normal loads you would likely be ok just.

 

Foam barrier works great on my CPUs in both laptops as well. Highly recommended. @D2 Ultima - you got yours set up yet, bro?
@Mobius 1 - you going to do this with your special heat sink as well?

 

Why do you have foam on your M.2 heatsink?

 

Great question. I think you are the first that asked. It is not the M.2 drives. Those are off to the left and not fully visible in the photo. (You can see the end of them at the edge of the photo).

That is a finned aluminum heat sink on the CPU MOSFETs, chokes and VRMs that have absolutely nothing to cool them. The white foam is very dense (the stuff Clevo uses to ship stuff like GPUs and heat sinks) and holds pressure on the heat sink and presses it against the thermal pads after the bottom cover is installed. I did not want to permanently mount it with thermal adhesive, but that dense foam spacer works great. It sticks with the thermal pads alone, but that foam works perfectly to slightly compress the thermal pads and keeps everything in place.

I probably will go ahead and permanently mount it with thermal epoxy at some point, like I did the cooler I made for MSI's naked, uncooled PCH chip (pictured below). I can't believe so many of these laptop makers care so little about cooling components that need cooling. It's like they don't care and maybe even hope stuff dies shortly out of warranty so they can sell another one. It's pretty sad. The mod below shaved about 12-15°C off of my average PCH temps.

The copper shim is attached to the PCH die with Arctic Silver Alumina thermal epoxy and the 3 finned copper heat sinks are attached to the shim using the same.

 

That's what i was searchig for. I don't care about OC.

 

Mine are stock clocks, undervolted only difference. GPUs both sit at 187-190 watts each Max and the CPU currently is sitting at 55 watts but I'm not doing anything crazy right now CPU wise

I wont undervolt kr anything. I will just leave it as it is and do my gaming or work.

 

I understand, but undervolting doesn't effect watts. But my system wouldn't run on one power brick correctly if I play anything even some what demanding.

But I mean you wont really know unless you try.

Sent from my XT1585 using Tapatalk

 

What will happen with Cpu Package Power (Which is measured in watts) if you undervolt your cpu and run Cinebench R15 with lets say 4.3GHz ?

 

What if i disabled sli ?? Wont be this be the same as using one gpu??

 

No clue? But I will change my statement as I was just reading up on wattage and voltage relationship. Undervolting does lower the watts... It's way to confusing to go into more detail lol

Honestly I can't say, I would think so though

Guess i would give it a try when i receive my laptop.

Sent from my SM-G950N using Tapatalk

 

Exactly. Cpu Package Power aka the processor's power consumption will be reduced with undervolt. The more you can reduce the volts, the lower the watt consumption will be. Lower power consumption aka watts = Lower temperature. It's like...

 

Got mine, will be installing soon @Mr. Fox

As soon as I do we'll see how much better this thing is

 

One last question. How often do u repaste ?? Because i can't do it and will be expensive to send it back to HID for repasting. Btw i wont change any configuration.

Sent from my SM-G950N using Tapatalk

 

That is going to vary by thermal paste. Some only last a couple of weeks before temperatures start to degrade, and liquid metal can go as long as several years without evidence of degradation. Most of the better normal thermal pastes last a maximum of 6 months before temperatures start to creep upward, and if you're lucky you can go for a year if all of the conditions are right and you can live with gradually increasing temperature. Equally important is cleaning dust, hair, lint and other crud out of the fans and heat sink radiators every 30 to 60 days. That causes more harm to temperatures over time than degrading thermal paste.

When you say you cannot, does that mean a physical inability (we have had some physically disadvantaged members in our community) or don't have self-confidence to attempt it? Is there nobody (a friend or family member) you know that can help you, or a local shop that you can pay to do it rather that sending it back to HIDevolution?

 

I sent my old alienware 15r3 once to a technician. But i don't if he can do the same with clevo or not. And yes i don't have the confidence.

Please make a point of correcting that. You really owe it to yourself. It is economical and gratifying to be able to work on your own systems. You seem like a really intelligent person. Anyone with ordinary intelligence can learn do it with simple tools. The idea can be intimidating if you have never done it before, but it is actually not difficult at all to do this on most laptops. The only people that should not are the haphazard and accident prone people that break things by just staring at them.

 

thanks for encouraging me, and yea as an Engineer i know i can do it, but sometimes when u buy something expensive u just don't want to play with it . And thanks again, and i will try it if its needed.

My prep work for the curious minds...

 

Next prep work will be when my 17w/mk AlphaCool thermal pads come. It is taking a very long time....

 

@Ground_Zro Can I ask if the 4k display on your P870KM1 is serving you well?

 

At the very least the DDR4 does not need ram sinks

 

Yeah it works great, I use it for both games and movies. Any specific thing you want to know about?

Sent from my XT1585 using Tapatalk

 

HA Ha ha I already knew that, as they're running at stock speeds. I just had to put them some where, because the back lid wont close. It's like adding a wing spoiler on back of a sports car when there is a speed limit in your country and no down force is needed! but it looks good

I wonder why they call them RAM sinks anyways?...

 

Because they were originally used on ram chips back when they actually got hot. You would stick each of the squares on the chip on your GPU when replacing the cooler with something like a zalman one.

 

That explains. Thank you.

My laptop now looks something like this:

#Gross!

 

If you now keep the back off and have fans blowing over it, those ramsinks will help a lot

 

How hot were the MOSFETs getting without the heatsink?

6 phases should be enough for a 7700K and no heatsink is better than some of the crud they put on desktop boards.

 

The bottom is now naked. I have stripped the insulation that came with the laptop and have a custom laptop cooler (but still needs improving). The RAM sinks do not help with peak temps, but they do help to cool the main heatsink down much quicker. When I quit a game, the temps drop down a tad quicker than before. I have timed this before I added them on, as my friend gave me this advice and told me to run the timed test from the max temp till it hits my idle temp with "overclock" fan setting. It works a charm.

 

Is 4k like eye candy?
Ever wished to go for more refresh rate or better response times?
How other resolutions look like on that panel other than native
Like 1080p or 1440p?

 

Ok so let me start by saying I am not a monitor guru, lol. I can definitely tell a huge difference between 4k (3840x2260 actually) and 1080p. With the g-sync I have gotten up about 200 fps not that I could actually see a difference really. As far as the max refresh rate I have no clue. I think that 1080p looks amazing as well, I play some games on 1080p due to the fact I can't adjust the HUD in the games so I can barely see them in 4k. If I had the choice I would get the 4k screen again just because it gives me the option to use 4k or anything lower.

When I mentioned high refresh rate I meant of the 3K(1440p 120fps 5ms TN display panel)

 

Lost me there lol...

Sent from my XT1585 using Tapatalk

 

I know most of people are using the 3K 120hz, but is the 4K 60hz worth it, if i ordered the 1080 sli ?? because i am thinking of upgrading, and i wont change this laptop at least for 3 years unless there is some new configuration that i can change later.

 

So I have it and I plan on keeping this for at least 2-3 years but I travel a lot so a desk top isn't practical. But honestly as far as the 3k 120 and the 4k 60, I have no clue. Not my area of expertise lol

Sent from my XT1585 using Tapatalk

 

Same here. The only experience i had was the Alienware 15r3 1080p ips with 60hz, so idk how it feels to have the a 120hz, but i know that starting from next year a lot of games and programs will support 4K and i don't want to miss that, yet how long will my GPU will be able to run at 60fps !!

 

Again not a computer expert but I know my SLI works wonderful with Witcher 3 in 4k and I know that's is currently a more demanding game

I've moved from an Alienware 18 which was 1080 resolution and at 60hz, moved to the P870-G with the 980m sli, moved to the 4k screen, also 60 hz. If you've never done anything higher than 60hz, you don't feel like you're losing anything. With the new KM1 I have now, i decided to keep the 4k screen. Because I like the fact that it has more colors, and the screen seems to be more vivid to me. I don't play many FPS games, and so, the higher refresh rate wasn't so attractive. I don't mind the windows 10 scaling too much. Not ideal, but not a deal breaker for me. I think you'll be able to live with the 4k screen for 2-3 years. Especially if you watch lots of movies and don't play many FPS games. Games look more vivid with the 4k screen. that's my 2 cents

 

I am not a big fan of FPS, but i play games like AC, dishonored 2 and NBA 2K, and to tell u the truth, i dont even know the difference between 60hz and 120hz. Tried watching some videos but didnt see any difference
