*** Official Clevo P870TM Owner's Lounge! ***

So around 4.3Ghz with all cores loaded and 10c cooler than the 4.8 and 5.0 modded desktop chips. It is much closer to the silicon's sweet spot so not too surprising.

On the GPU front have you done any analysis on the vapor chamber in single card mode? Have you tried running two heatpipes accross to the other blank side? This would be how a 1080ti style card would have been laid out IMO. I bet the chamber is only running around 70% efficiency in single card mode with the current arrangement.

 

Actually, almost no one orders the single nVIDIA GeForce GTX 1080 without the Vapor Chamber heat sink set-up, so I am only reporting with it.

No, we don't mod the pipes.

1080Ti?

 

Yes, Nvidia denied clevo making one but the heatsink/power delivery would take a single 1080ti core on an extended PCB (think the original 980 PCB).

You would have had a layout like:



Where the red lines are where the heatpipes would be (the mounting holes would be wider and the core position would have shifted too) and the blue line is where it would cut off in comparison, a "V" shape leading into the fin part.

The vapor will struggle to move in this direction in single card configurations which is why I would say it's not being fully efficient in that configuration at the moment. Ideally you would add these extra guides for the vapor to get the most out of it.

Ah the machine that never was.

 

Phew! I almost thought (before I've read what Meaker@Sager wrote) that the GT75 somehow defied the laws of thermodynamics (I know that it probably has the best cooling system in the BGA land, but...) and it was tested at 4.8Ghz (for all 6 cores!!!) vs. the evoc p870 at the same clocks and the GT75 ended up having lower CPU temperatures!!!

Were these temps obtained under combined tests or in separate tests for CPU and GPU?

Did you have the opportunity to test the highest config (8700+p5200) for the msi WT75?

 

Did you miss the part that I have now bolded?

 

Yeah, I did missed it at first, then I got back to that post and everything made sense

Thank you for providing the data from your tests!

 

Still the better cooling is still the 5ghz chip Vs the 4.3ghz only running 10c hotter.

 

The Cpu temperatures will explode once you pass 4.5Ghz on 6 all cores in the Msi Gt75 Jokebook. Stock clocks, but with default voltage showing that. Higher clocks need → Higher volt. Higher Volt = Higher temp Yeah, everything makes sense

 

Guys, I want to buy an P870TM-GS with the following config :
- 8086k or 8700k and keep it@ 4.5 GHz
- 1 x Nvidia 1080
- 2x16 gb ram
- 2 x Samsung m.2 nvme 970 512Gb
- 2 x 1Tb Sata SSD
- 4k IPS Display with G-Sync

The seller is giving me "Dual Full Range AC adapter, AC in 100~240V, 50~60Hz, DC output 19.5V, 11.8A, 230W with Power Converter Box AC-200"

Do you think that a single 330w power supply is not enough for my config?

Thanks.

 

You can clock down the Cpu clockspeed. As it is now it's near the borderline. I expect you talk about use a single brick for travelling (max portability). But use dual bricks home.

 

Thank you for the answer.
Yes, I plan on travelling with only 1 power and have 2 at home.
Having 2 in my backpack is way too much.
Do you think If I give up on storage will save some energy? Like having only 1 m.2 and 1 sata?
In your opinion what would be the config that will fit in 330W and be absolutly stable?

 

This don't make the big difference. Just use ThrottleStop (can put in 4 power profiles). Use one of them for portability with sigle brick (lower cpu clock speed). Probably right below stock clocks (4.0-4.1GHz all cores) with a decent undervolt.

Edit. Another option is buying a single 780w power brick.

 

Can't you disable SLI so you should only need one brick for the 8700K and 1080?

 

Read!! His Specs

 

I stand corrected. Then shouldn't 330w be enough if it's the same for the P775TM1-G ?

 

I said "it's near the borderline". You will max out the 330w psu. I mean P775TM1-G have a lower Power Cap in firmware vs. Clevo P870TM1 who is intended for 1080 Sli. Hence I said he should put a bit lower Cpu clock speed.

 

As he aaid, you can push it on a single brick at stock but going much further is risky.

 

I see, thanks for the information. Always good to know.

 

I did not know that they are making 780W bricks now... can you link me the model please?

 

Google same Psu model. https://www.ebay.com/itm/780-Watt-AC-Adapter-110V-250V-for-Clevo-P870DM-DM3-KM1-TM1-P775DM3-TM1/132624813469?hash=item1ee10e0d9d:m:mCuMn__e2cikAsghTUILTEA&var=431959743063&_sacat=0&_nkw=780W+AC+Adapter+Clevo&_from=R40&rt=nc&_trksid=m570.l1313

+ HIDevolution sell it for their Clevo build.

 

Just note, if you are working on sites that require safety certifications the 780w does not have them, if you are not then it can be handy.

 

With a single nVIDIA GeForce GTX 1080, the EVOC High Performance Systems P870TM1 comes with just one 330W AC Adapter, which will be plenty.

It is only DUAL nVIDIA GeForce GTX 1080 in SLi that required 2x 330W AC Adapters.

 

Was thinking about getting the 780W one just for the hell of it till i looked at the price...

 

Edit's post and this seem kind of confusing. Is the problem his reseller is providing only a 230watt brick vice 330w? Is that the reason his system will need to undervolt? Is a single 330watt brick sufficient for overclocking the 8700K, even with only a single GPU, or should new buyers consider the second brick as well even if non-SLI?

See... Msi Gt75 with stock clocked i9-8950Hk BGA + 1080 pull 374W from the wall. I'm not sure why MSI didn't delivered the Turd with single 330W brick as previous model. But expect higher numbers with @Prema firmware and oc'd i7-8700K/8086K running +5.0GHz and maxed specs (ssd slots, ram slots filled up etc).

 

Isn't that strange though? Doesn't the P775TM1-G use more power if overlooked?

 

Depends on the power cap for P775TM1-G. @Prema firmware will circumvent that limit. And I don't know what's max power cap is for this model with stock firmware. As I said in my post... Msi used 330w psu for previous model with unlocked BGA and Gtx 1080 but they skipped the idea with single 330w brick for the Coffee lake i9 BGA model with same graphics.

 

Confusing in what way? I say I laid it out pretty clear, gave my spec and the fact that the seller is ONLY selling it with 2x 230 W bricks and I would have liked 1 x 330W.
I would have liked 1 x 330 W brick because I will carry this machine back in forth quite a lot, not daily but several times a week.
On top of that setting up takes more time, you need more bag space, desktop space, 2 free wall plugs.
In the end I don't mind buying one extra 330w brick to travel with but I would have liked to know that my config works on a 330w brick.
I will undervolt probably and cap the cpu speed while on the 330W brick.

 

There are lots of sellers out there...find one that will sell it to you correctly.

 

Overclocked MSI jokebook will draw 400W from the wall if fully loaded. 200W GPU, 150W CPU+mainboard, RAM, drives, LCD panel, and that may trip the Delta 330W PSU into emergency shutoff. A normal user would not encounter this limit, but someone doing stress tests could quite easily. That's if the EC or "Zener diodes" allow the CPU to pull more than 150W without shutting the laptop off and making it reboot in half a second....

 

What's the VRM rated for in it?

 

If you only need 1x GTX 1080, then why not order the P775TM? The P870TM-GS will be much more expensive with the same config (€ 300-400), if I'm not mistaken

 

It does give some power and thermal headroom.

 

I had a hard look at the P775TM also, it was almost good but since I had a good run with the P870DM so far decided to stay on this chassis

So, what made me chose the P870TM in the end :
- better speakers
- headphones jack on the left side of the laptop so I do not bump into my headphones jack with my mouse
- USB port on the back - this is where my mouse connector lives - I don't like having my mouse plugged on the right side to bump into the plug while gaming
- 3 usb ports on the left
- better cooling (especially on the 1080 due to 2 fans cooling design) leading to lower noise and better OC
- I get a very good quality 4k IPS G-Sync display free upgrade - the alternative was an TN panel that would have been great for gaming but I need this laptop for work also and I need a good display with good viewing angles and colours
- more storage space and from previous experience better drive cooling on the P870 due to placement and design (especially on m.2) - also on my P870DM I did not experienced any heat transferring to the palmrest from the drives that are on the other side and it's a plus for me

 

It's a fair upgrade for those who don't mind a slightly larger and more expensive machine.

 

In my opinion there is no better alternative to the P870 out there and I haven't seen other brands working on one in the last 2 years...
I would have liked a little more competition in this area like I would have liked to be able to upgrade my videocard in the P870DM-G that I own....

 

That would have needed a significant market as the card would have been a different design to the new ones.

 

Those are mostly true , tho the display should be available on both

Check the build in my Signature, especially the case, it is 2 times as thick as a P870, but other than that, the same size, and it has more power

 

Well more power in some situations and less in others depending on the game while using twice the volume and being heavier with no battery, keyboard or screen @Georgel

 

How much more power? Can you run same bench and post your results? Compare with https://www.3dmark.com/fs/15048133

Or did you mean pure Cpu power?

 

Agreed, but in my situation alone I had multiple mice, multiple keyboards, multiple monitors. But agreed, it isn't as efficient for portability by any means.

GPU is 1080TI instead of 1080, and the CPU, well, not more than yours, since you actually get better scores than me, but more than the average Clevo lappy.

This is keeping in mind that the good Clevos are made by 3-5 companies in the entire world, while all Clevos are sold by over 50 companies. The idea is that you and those purchasing from HID, Sager, and other good companies are the few ones, compared to the entire number of Clevo companies that exist out there...

One thing my dekstop isn't is silent lol

At least under load, it is more or less the same thing as a Clevo P775DM3-G, but in idle, it is more silent. I suspect that P870 is more silent than P77X though.

 

the silent fan profile is an issue with p870tm. fan doesn't spin probably until you hit like 80C+. I'd like my cpu to stay under 80C at anytime, not even 1-2 seconds peak if possible.

 

Don't want to rain on your parade, but a single 1080 ti does not beat 1080 SLI desktop or laptop setups.
And my stock Sager P870DM3 beat pretty much everyone right out of the box with no mods.
And Clevo is made by 1 manufacture not 3 to 5. Unless you meant to say resellers that resale the Clevo under a different name.

 

I would take a single 1080ti, it's not far off 1080sli when both are tweaked and has less driver issues.

 

I currently own both options

Going to have to disagree with you on this one.
We are only looking at FPS and not the score or total score.

 

*If your software can use SLI, mine can't so 1080TI is infinitely better than 1080SLI for me.

As for what your P870DM3, yes, that is the issue. Also, that is the issue as well, there are resellers who mod them heavily and rebrand them heavily op to the point where they are totally different products. A Clevo laptop from Romania will throttle almost out of the factory, after 6 months of usage will reach 98C on CPU at default clocks, so you have to undervolt and underclock just to keep it cool, and about after 9 months of usage will overheat on the GPU as well, making it practically useless, or rather a circuit toaster.

That is what most Clevo laptops are like, considering that the better resellers and modders sell a minority of laptops compared to the whole number of Clevo laptops out there, resulting in those laptops being of very varied quality and performance.

I would also take 1080TI any day of the week, any software can use it, while for a SLI setup only 1 or 2 games from my entire library , and no software, could use a SLI...

 

If it is not Prema mod enabled, then the fan profiles will be the worst thing in temrs of fan profiles out there. With Prema's help, it can get to be a really good equlibrium between temps and noise though

 

Okay, I can totally understand that. I personally would take a Titan V over any single TI.

One needs to understand.....When these laptops leave Clevo, they are configured with a broad voltage & power scope. This has always been the case. And what you call undervolting we actually call. "Putting in the correct values" And since you have been here for quite some time, you also know that we have mentioned this more times than one cares to count. In Romania's case (Speculations of course since I do not own a Romanian version) Your cpu is configured to run something like 1.3V right from the get go. And your watts are like 65W -113W. Instant heat and throttle. When in fact it should be something like 1.1V/120W. These laptops also come from Clevo with no heat sinks installed, but have thermal compound on them (Just to say they are not the ones finalizing assembly). It is also noted around the world that all these cpus run hot. That was before they even ran in a laptop. (This is just to say...One needs to understand what one is getting into - If they have beefier heat (Desktop or in your case - mini) sinks or water blocks for a reason....Chances are our less than half mass heat sinks will not be doing better than theirs) Business folks really do not see these problems as much as they are not running around trying to beat the system by over clocking. In the case of the laptop. "Undervolting" usually corrects that. Also they do not want to run around redlining their cpu and gpu 24/7. Not to mention it takes a certain class of folk to even want these types of laptops(Under no circumstances are these laptops user maintenance free out of the box). Most can do what you're trying to do with a $1300 to $1500 dollar laptop. And never skip a beat. And as Meaker pointed out earlier with a 1080TI as not being that far off 1080SLI I will make almost the same comment then. (A 1080 is not that far off a 1080TI - If that's the case.)

As to fans. John@obsidian-pc is making the fan situation a much more enjoyable experience. You might want to check him out.

 

prema mod unlocks the bios but fan profile is within the EC i believe. it doesn't affect fan profile and unlocked bios have no option to choose it because software like CCC from clevo exist. issue with mine is that im on server windows and CCC doesn't work and even if it did, its not all that great.

someone from baidu had made another sw that controls the fan and works on clevo machines tho, so no problem all good.

 

Well, I had a 1500 USD Laptop before, and it was even worse for rendering and doing my typical job

It was an Acer VN7-791G, it would throttle even more and sit almost always at 95C during my typical work loads, so not a chance I am considering that again for work...

I should add that I most probably have a different workload / typical work profile than most people, so I can give you that, not everyone will require this much power for sure. I mean, even for gaming, the typical 1500USD Lappy is pretty good, there the GPU is the limiting factor. It isn't like most people need this much powah in the GPU, it is more like I need it because of the way I work.

Speaking of GPUs....

Titan V does not exist in Romania, so no chance of me getting one yet. I think that 1080ti will be out beforre Titan V...

@Prema can change the EC as well, and you wouldn't have to install or run CCC in that situation (?)
