*** Official Clevo P870DM/Sager NP9870-G Owner's Lounge - Phoenix has arisen! ***

On the GT80 the slave will normally run 10c warmer with stock fan profiles but I haven't ever had one get to 90c. You might ensure you fan profile is set to overclock or custom in the management utility as this will help ramp up the fans quicker and with more duty cycle. The stock vbios should have you covered for safety but I understand 102c does seem a bit on the high side and we all know high temps hurt longevity on GPUS and it's always an easy first step to repaste especially if it came with factory compound. I would try ICD, Antec 6 or something well known first before going with CLU on the GPU as its easy and will tell you if you are on the right track. Let us know your results.

 

Kryonaut is apparently the new king of non-metal-based TIMs, with ICD and Gelid Extreme close runners-up (according to tests/reviews).

Truth is that the difference between these TIMs is a few degrees at most. I prefer how easy Gelid and Kryonaut are to apply and remove (gotta be careful with ICD when removing/cleaning it).

The only time you'll really see a large difference in TIM performance is getting Liquid Ultra, but that's a whole other ball game.

 

I didn't know that SLI doesn't work in windowed full-screen mode.

 

Lapping undoubtedly has an effect, but it is only a couple degrees. First and foremost is a good paste job. Next, switching out the thermal pads. Then lapping. Lapping can have as much of an effect as the pads. Between the three, you MAY be able to get 10 degrees, but no guarantee (assuming clu). But start with pasting, then pads. A good lap (sanding and polishing) takes time and practice. Only now can I do it more quickly and with better results. Practice on something you don't care about, because if you mess up, you have to go back a step or two to fix it!

 

I think the single action you can take that will have the biggest effect on temps is de-lidding, cleaning the gunk Intel puts there, and then applying some good TIM between the die and IHS. Though this is pretty much the same thing as your #1 item, that being a good paste job.

 

Update on SLI temps:
I now chose overclocking fan profile. Temps after 1 hour of Heaven with both GPUs overclocked to 1260 MHZ:
Primary GPU: 67c
Secondary GPU located in the middle: 78c

CPU: 61c

In the end it was my fault not using OC fan profile from the beginning. The cards are already assembled with IC Diamond, so I will not repaste for now.

I think the temps are o.k. now. However fans are really loud now so for gaming I will need a headset. The unit is much louder than my Batman, but hey, it´s SLI.

Matrix Leader has posted his SLI temps in another thread and they are now very similar to mine, the slave GPU being about 12c higher.

So I think we can conclude that the fan/heatsink in the middle (which is also obviously smaller) has a weaker performance than the fan/heatsinks located on both sides. This must be the reason for the higher slave temperature. In my desktop PC both GPUs have the same temperature, so I don´t think one can say that the slave GPU has generally higher temps. It´s just a weaker cooling solution in the middle. I wish Clevo would have chosen to use 3 identical fans. Maybe this would have made the unit a little bit wider. It´s also possible that Clevo constructed the P870DM with desktop GTX 980 in mind. Anyway, not using 3 identical fans is an imperfection to me, otherwise it´s a nice machine.

Maybe I will try to connect GPU1 and GPU2 with an additional heatpipe when I have the time to do it.

In the end I will keep the Phoenix and sell my Batman ;-)

 

Make sure you read this bro:

358.91 Fries GPUs

 

Can you hear the difference between slave and normal gpu fan ? For me that would feel annoying if there was an audible difference.

 

I can't

 

I can't also. But it is loud and I suspect the loudest fan could be the one in the middle. Is there a possibility to read the fanspeed with a program. Aida64 can't.

I'm seriously considering delidding the CPU as soon as I get, I wish @Mr. Fox would have made a video of the procedure too maybe I'll go with the hammer solution I wanted to ask if you needed to adjust the socket in any way in order for the retainer to hold the CPU? When I googled delidding, there was also an enthusiast who showed that the socket screws had to be adjusted with nuts, because the IHS is pretty thick as you mentioned, otherwise it would be close enough to the heatsink.

I'm also curious about the G-Sync capable GPUs. If I was to buy an external LCD with G-Sync, do I need the G-Sync capable GPUs? In my understand (of the promo materials) the G-Sync LCDs have an extra part inside, or is it just a marketing move and it's only a matter of certification and firmware of those screens and therefore I'd need G-Sync GPUs as well? I'm quite confused.

 

G-Sync needs a small board installed to G-Sync capable screens to link with a G-Sync capable card to perform said function.

EDIT: And even then, it may not work because of certification of parts and compatibility.


Now for the waiting game... 7-12 business days once parts come in (which are backlogged...). Damn you queues!

Mobile G-sync uses no extra hardware, it uses the capabilities on of eDP panels to control them. It's a firmware/software thing beyond that.

 

His question was regarding the external display. As for mobile... I dont know too much on that one yet.


Sent from my iPhone using Tapatalk

 

Ah yes in that case desktop G-Sync for now needs the module yes.

 

I'm also considering doing this. It seems to take 10C off the CPU temps across the board under load, and is the single best thing you can do to lower temps. Between that and under-volting, should see a 15C drop in temps...I hope.

 

It does, but not as quite as well as real full screen. It is still more powerful than single GPU. SLI also works in Window Mode when not full screen.

Unless something has changed, CrossFire does not and only functions in real (non-windowed) full screen mode.

 

Mantle and DX12 native applications will IIRC but for current titles it still applies crossfire wont run in windowed mode.

 

i cant seem to find benefit of working in window full screen mode, to avoid alt tab which takes only few sec. machine is hella fast, unless one would want to monitor temp and other stuff with other tools at the same time..

 

Playing Eve where you are mutliboxing is one example or streaming it can help.

 

I few seconds?! I don't have that kind of time.

Plus often I like being able to see the status of the game in the background when I'm alt-tabbed.

 

I never thought about that much, but realized lately how nice that is. h1z1 doesn't have a windowed mode in the setting anywhere, and I would have to constantly tab in and out to check queue times, which are all over the place. After figuring out how to do windowed borderless mode, it's so much better to be able to do something else and not have to keep checking it.

 

I always always always play every single game in windowed mode. I'm glad nvidia gave G-sync the ability to run in windowed mode. Was incredibly frustrating when initially it required true fullscreen to function

 

Nah, don't do that. It's super easy with a razor blade. Look at the photos I posted. There's already a video of how to do it. The PCB is thinner than most CPU and I would hate to see you break it using the " don't force it, get a bigger hammer" approach. This guy has a few good videos on his channel.

I know some people like doing that. I've been a multi-GPU guy for years. I don't see that changing, and maybe the fact that full screen is better has something to do with that. Or, maybe it's just what I am used to after about 18-20 years of doing it full screen. But, I am curious and never asked anyone that likes it. Why do you prefer windowed mode? I know there has to be a reason you do, so I am asking for my own interests and not passing judgment on your preference.

 

Do you guys use BIOS boot or UEFI boot? Also my Killer ac1535 seems to kill my connection when under load when bandwidth control is enabled, any ideas?

 

I use UEFI offcourse for faster boot.

Regarding the Killer AC1535, you need to uninstall the drivers to get rid of the bandwidth control app and then reboot. After that, do not install the driver by running setup, instead, go to device manager then right click on the WLAN Card and 2 Ethernet devices, choose update driver, then manually point it to where the Killer drivers are located. Example of the path where it would be:

For Killer AC1535: D:\Drivers\Clevo P870DM-G\Drivers\03_Lan\drivers\Production\Windows10-x64\k1535w10

For Killer E2400 Doubleshot LAN: D:\Drivers\Clevo P870DM-G\Drivers\03_Lan\drivers\Production\Windows10-x64\ke2400w10

 

So you recommend to use ac1535 without the app? I assume that installing that way forgoes the app?

that's exactly what I said in my post. The app is known to cause problems such as the one you mentioned and/or BSODs. That is exactly why I didn't go for the Killer AC1535 in my Phoenix and chose the Intel AC8260 instead. The Qualcomm drivers are absolute garbage just like nVIDIA. The Bandwidth control sounds great on paper, give the apps that need the bandwidth most the highest priority, but take this into real world usage and it's only asking for trouble. This has been ever since the days of the Killer 1202 and until now. Some companies just don't learn

 

I see, perhaps I should grab an AC8260 for replacement off eBay.


Sent from my iPhone using Tapatalk

 

That would be the best 50 USD you'd spend believe me.

But still, you will have to uninstall the Killer Suite and manually install the driver for the Killer LAN 2400 cards.

Just go give you an idea about the Intel AC8260 ping =

 

I even ordered another 1535 to see if it fixed the problem but it does the exact same thing, so I did not have a faulty card. Sad that it tarnished my initial Phoenix experience a little bit. Just ordered an AC8260, will see how it goes. Luckily I can still return the extra 1535 I got.

A bit weird to have two lan ports otherwise though, I assume its sole reason for existence is for the killer doubleshot?

I guess, never used LAN cables/ports in 10 years. Wireless FTW

 

still using lan at work to connect to our internal network

On a brighter note, what kind of OCs are people getting on the 980 with the stock vbios?

 

havent seen anyone with a 980 yet. i think users will just be starting to get those in currently

I also only ever play in Windowed mode if I can. Main reason is the ease of moving between programs, being able to see a bit of what's going on in the game in the background. I can have a few windows open, re-sized, and still see the game.

 

100% agree with this statement as a hardcore daily gamer I simply cannot use SLI without wanting to pull my hair out.

 

I'm in the process of buying a Sager variant, but wanted to thank you for the heads up on the network cards. I will opt for the intel card.

 

Update: Just a heads up for anyone stuck in the same situation. My AC1535 seems to be fine now, I had Doubleshot Pro option enabled without any ethernet cables inserted, seems like it was causing issues.

However, still opting for the intel card seems to still be the smarter choice, will have compare them when I receive my intel card anyways.

 

Well i decided to go with mythlogic after all and pay extra for QA. I am just reading to many horror stories about Sager.

 

yup not the best idea to buy from sager directly. rather go through their excellent resellers like xoticpc or powernotebooks, for example

Ah OK, sure... that explains it. Our use patterns are totally different. I NEVER, EVER multi-task when gaming. When I game I am truly immersed and will not allow myself to be distracted by anything else. Gaming is (1) an escape from reality for me--which is probably why I do not enjoy online multiplayer; and (2) just another good (and fun) excuse to bench/overclock the crap out of my hardware. Without SLI, the numbers are always a disappointment to me. I almost will not consider a single GPU machine for anything because of my overclocking fettish. This Sky X9 is actually the first single GPU machine I have used in about 6 years that I did not think was a weak and pathetic piece of junk, LOL. Plus, I almost never have "issues" with SLI. I do sometimes have issues with lazy game devs, or stupid ones that like to use broken game engines that do not support it, but disabling SLI for the sloppy piece of crap games works just as well as a machine without SLI, so there is nothing to lose and everything to gain for me. Look at it like your bottle of nitrous, ready to boost your butt to the moon and back at the flip of a switch.

The beauty of this machine is its capacity to satisfy the "hardcore gamer" and the "hardcore overclocker" or the deadly mixture of both.

Let's not forget the folks at EUROCOM, which would be the only vendor I personally know about that deserves any degree of thanks for helping and contributing to making this awesome machine have the ability to perform like a banshee with Prema's magic firmware. I know there are other Prema partners and don't want to miss credit going where credit is due, but I'm not getting any kind of communication or questions from them. I hear from EUROCOM every day, without fail. They do not sell "Clevo" notebooks. They sell unique high performance machines that are for people that appreciate something more than the norm, and don't want to be identified among the status quo. I know there are few out there like that, with the same passion for wicked machines, but not very many when you look at the industry as a whole. I wish there were more extreme performance vendors than there are. I know of one whose name starts with the letter "A" and now all they sell is really nice garbage. I won't mention who that is right now, but they lost their first love and now they're losing customers because they sold out to the namby-pamby panty-waists that are OK with expensive junk as long as it looks fancy and daddy pays for it with his money.

Speaking of 'another excuse to bench the crap out of my hardware'... here's one. I did this for the G-SYNC and v-sync fanboys, and it's really impressive to look at... drop-dead gorgeous. But, I'd rather have no G-SYNC, dual GPU and triple-digit framerates. There was no point in overclocking the GTX 980 with 1080p G-SYNC, so I just overclocked the crap out of the CPU so I could show what nice temps it has.

As a poster above mentioned, it's mainly for multitasking.

I use true windowed, and not windowed fullscreen, so I can see my taskbar and see if I get a message on another platform and tend to that.

 

Wow, finally, a Notebookcheck review that I agree with in spite of their technical errors, LOL. They chose the right performance winner for a change, too. They often get so hung up on stock configuration to such an extreme degree that they totally misidentify the true performance winner. The other two turdbooks cannot hold a candle to this machine with sissy-boy BGA CPUs welded to their mobos. They obviously don't know how to make their own overclocking headroom. The BGA CPUs are shackled and predestined for mediocrity at their finest, but the 6700K is not.

There is nothing wrong with doing it any way you want to do it. Since I don't allow myself to multi-task or be disturbed when gaming, the full-screen exclusive focus mode works best for me, and delivers the best performance. Honestly, I'm not good at multi-tasking any way. It pisses me off, and I suck at it, so there's that, too. I can just barely walk and chew gum at the same time, so I focus on doing one thing at a time and try my hardest to it extremely well, LOL.

 

I really appreciate all the info you have been putting out. I really wanted a eurocom, but just couldn't justify paying almost 700 dollars more for the same laptop that I could get from mythlogic. If they were to price match them I would order from them right now. That being said I think mythlogic has made a name for themselves making great systems. Both are licenseed by prema so I just couldn't understand that massive of a markup.

 

Eurocom prices are always a rip off for US or international sellers... Get mythologic...

 

just out of curiosity why is it that sager has such terrible reviews online. How much different are their systems from a reputable clevo builder.

 

its not their systems but their service that seems to be quite subpar...

 

I have a daughter just shy of 3 years old, and a seven-month old son. There's no such thing as just gaming - by the time they go to sleep and I have maybe an hour to myself, there's a ton of other stuff I need to do - bills, budgets, emails, etc. Rarely do I ever get to "just game".
