*** Official Clevo P870DM2/P870DM3 (Sager NP9873/NP9872) Owner's Lounge! - The Phoenix 2 is here! **

Put on ICD, tighten the screws and then disassemble heatsink again. See how good the paste is spread. Clean up again and repaste. Maybe you got a lemon. Heatsink from Clevo is a hit or miss!!

 

This Cpu i have used in my previous p870dm with no problem, Ok thanks guys ill try it

 

With the lemon... I meant the heatsink

 

Yeye i know ahahha

Anyway guys, application with ic diamond is better on this pc.. Now i dont have any problem in temperature.. 0 throttling

About nvidia sli what is better..put physx on secondary GPU or on Cpu?

 

Their sales are being held up buy poorly implemented cooling system.

 

Interesting .... hopefully that means that they wont change the motherboard or connection and therefore prevent changing out displays. The way things have been going, you never know ...

 

You only need ~1.20v for 4.0-4.2ghz
Try 1.25v for 4.2ghz?

 

Then its the (warped) heatsink! No CLU then!

Just let the application decide where to put the physx (automatic settings).

 

Ye i can confirm it, the heatsink is not good for CLU..icd is still the best for it

 

Then I would have it replaced.

 

I've said this tens of times, but Papusan doesn't believe me

 

Well, the reason is because he knows from first hand experience that it is not accurate. But, it is accurate if your system has deformed or sloppy fitting heat sinks that do not fit correctly, in which case ICD is the only product anywhere that will work well. Under a heavily overclocked load, the Sky X9 and my own P870DM-G ran a solid 20°C cooler with CLU than with ICD. If ICD was truly better, I guarantee you we would both be using it instead of CLU. With correctly fitting heat sinks, CLU does a remarkably superior job when the fit is proper.

 

On the desktop side IC Diamond is about just as good which may be why you think that? Liquid ultra works far far better on delidded cpus. I'm not sure if that's the case on the P870DM (idr how the socket works since I've never considered one) but on most other soldered laptop cpus, they are delidded which makes the liquid ultra quite potent. On a desktop the thermal compound under the lid is not liquid metal so putting liquid metal on top of the lid does not produce great results. But every test I've ever seen where they delid the 4790k or 6700k or whatever and reassemble it, the temp drop is huge compared to every other compound.

 

Yeah if he get a lemon. Heatsink from Clevo is a hit or miss. As you can see... Now also with their newest models. Take a peak. And you will see different max temperature on a lot of the new systems. QC is almost none!!

 

@Papusan

Maybe because my heatsink wasn't fitting perfectly.

Check my results in temps between IC Diamond vs CLU

 

I know that post bro. I also showed you the best way to apply paste on desktop processor, as you had problems with Liquid metal

 

How much wrapped dos it normally get, can it be fixed by aggressive lapping?

 

Its not much, just enough to cause issues. Multiple ways of fixing it, lapping would be the last one.

 

Would you mind mentioning those.

 

Like using a glass sheet to check how much its bent/warped and then using 2 blocks of wood (or books ) to bend it back into shape.
Adding/removing/replacing thermal pads to compensate for the gap.
Adding copper shims (not suggested)
One super extreme way : http://imgur.com/a/Gw2XM
Using thicker thermal paste.

There was one more that @Mr. Fox had mentioned, cant recall what it was.

 

Is it possible to output more than 4K at 60fps to an external display, or this is the limit of both HDMI and Display Port?

I need to buy an external display to compliment the FHD display, and I'm looking at a few options, but can't decide, and I started to wonder if the max refresh rate should be important in making the decision

 

Im guessing you meant 60Hz and not fps.
That is a bandwidth limit for the eDP port. External monitors should work over DP @ 60Hz+

 

The laptops themselves will work over 60Hz, but I'm asking if I can send more than 60 Hz through the cables. More like, is it worth buying an more than 60 Hz display, if I'm going to use DP cables?

 

Depends on the display.

 

https://en.m.wikipedia.org/wiki/DisplayPort

There's a nice chart showing the current bandwidth limitations for each resolution. I'm guessing there exists something similiar for the HDMI specs.

 

DM/DM1 models are DP 1.2 and max out at 4k 60Hz.

DM2/DM3 models are DP 1.3 standard and max out at 4k 120Hz.

Both DM/DM1 and DM2/3 can do 3k (QHD) 120Hz via DP.

 

DM2/3 internal DP is not 1.3 though? Only the external mini-DP?

 

Internal and external DP standards are a bit different. But certainly 1440p up to 144hz as this is doable on the old display port standards.

 

It kinda looks like the steam was let out of this thread and for the DM2/DM3. It could also be that everyone (the ones that haven't purchased a DM2/DM3) is waiting for that 1080p 120hz G-Sync panel.

My brother is still indeed getting the DM3 with the 4K panel but not from a Prema Partner shop, unfortunately. When I told him about the Bios and the ability to fine tune his computing experience, he started laughing at me..."that's why I have you" he said. Some people get it, most people don't.

 

Guys UHD & QHD 120hz display options will be part of alienware laptops and November is the time of its availability. Can we expect the same time frame for DM3 to offer those screens?

 

Yup, waiting for that panel held back my purchase. Now if that panel's release bumps up against the Kaby Lake release, and it's only a matter of weeks, then I'll wait to get the latest tech (I know it's only single digits % performance bump).

I mostly game on an external monitor so don't need 4k on my laptop.

 

End of Sept Beginning of Oct is what I was told for the UHD 1440p panel to start showing up with multiple vendors.

 

The 4K panel is backordered until late Sept for a lot of resellers but I haven't heard anything about a 1440p panel being added to the current DM2/DM3 models.

 

I haven't heard a date for Clevo to introduce that panel yet but other laptop manufacturers have been speculating on the release of their 1440p lineup. Its not in stone but that is the timeframe rumor they are scheduled to start showing up, just throwing out a heads up. I hope Clevo adds it to their list but only time will tell.

I believe Intel said the desktop Kabylake would be in January, so looks like more than a couple of weeks in between.

 

I can't get over how loud the fans are on the DM3. This should be a serious consideration for people that plan on having it close by and do not use headphones. Over 50db if I had to guess.

Can some please advise what the best custom settings are for the quiet setting in Control Center?

Can someone also please advise on the best setting for Physx? Auto, GPU2...?

Thanks

 

1) yes you aright, BUT i like it
2)put on energy saving with fans in automatic (if you want to play games you have to put on performance)
3)Leave on auto

 

Indeed. That's another reason all in itself. Such a shame...

::iunlock::

 

Ok, there is definitely something funny going on or my brand new temp sensor is faulty And these temps are not as they seem....
This is all with the bottom cover off and fans at 80% then they go to 100 percent if the temps stay around 90C for about 7 to 10 minutes or so....

When I test the heat off the vapor chamber. You know, the part right dead center over the gpu. The hottest part of the whole machine. Do you know what that reads?

65C. That's right. 65C even on all 8 screws holding the gpus down. The weakest point in the scenario.
75C. That's right. 75C without max fans.

86/90/85 on screen temps
64/68/60 on the heatsinks from the back with the fans pushing air through them. 80%
59/62/52 with max fans
75/75/70 on the heat sinks under the cover. The part directly touching the gps and cpu's.
65/65/52 directly on the vapor chamber and heatsink. max fans
And temps drop in os to78/81/around 75 to 80.

Anyone with insight, i'm all ears. I will test this further when I get back.

Room is 90F
Test is on it's 6th loop.
Fans have just about turned off and temps dropped to 72/74C
Now 80/82 and fans seem to be about 60 to 70 percent, maybe.
Now back up to 85/90 after a few minutes and fans still at 60 to 70% maybe.
Now back up to 80% and holding....

Hummmm.......

Thoughts

 

Embedded sensors directly in the die? What you are measuring directly on top of the die is probably 'tcase". Something different entirely....

If anything, the temperatures you are reading makes sense if the thermal probe is embedded in the die.

 

If you measure the temps on the top of the heat sink, i doubt it will be accurate, since the heat sink is hollow/not solid copper?

Havent had the pleasure of owning a vapor chamber heat sink before.

 

When I get back home what I'll do is I will try to set the laptop in a way that I can actually hit the die.

Very much anticipating the info. While you're at it can you infrared the VRM's an PCH?

Thanks.

 

Ok, so looking at the screw holes. This is right next to the core. Looks like i cant get to it directly unless i remove the middle fan, which i'm not going to be doing at this time.

while db 77/78/78 on 100% fans@ around 4200 rpm's
while db 64/66/65 on 80% fans@ around 2850 rpm's

Sounds levels vary off of your room temp and heat sink temps
4th loop 100 percent fans and temps are 71/73 on gpu..

 

Ok guys.....Check out the next 4 videos and give your impressions on noise. LOL. And one of these videos is a trick answer video so to speak.

 

Thank you for those videos!

But without a more objective noise to compare to, it's hard to judge if those noises are high or low. For example, a comparation with speaking voice at a similar distance as the fans are from microphone would give better clues for us, users who don't know how loud these fans can get

 

Lets not make it harder than what it is. You are not being graded. Just take a guess and wait for the answer.

 

Thanks for this! I can tell a difference with my Sennheiser Headphones...

 

Cool so impressions on all 4 videos please.

 

@Johnksss@iBUYPOWER Just listened to them. The 80% fan video sounds fine. The last mystery video sounds like they are 100% again.... ?
