CLEVO P870TM1

The P870 is still the world's best and last genuinely high-performance DTR notebook, regardless of whether it is EOL or not. It's really awesome that HIDevolution was able to work out a deal to continue offering it. Being they are a @Prema partner shop makes it all the sweeter.

 

What does DTR stands for?

 

DTR = desktop replacement

 

DeskTop Replacement
edit: Mr. Fox beat me to it

 

It could also stand for "deadly turdbook reaper" LOL.

 

Now that I read it seems pretty obvious lol

 

It is a beast and fun to play with certainly

 

The cpu fan arrived yesterday, I'm doing some tests but it seem to be alright. It arrived right on time sinve my desktop PC died a week ago lol

 

Here's the score I got with Heaven, CPU was limited to 85% max freq. What is the safe-max temp on the GPU and CPU on this thing?

BTW this thing is a monster.

 

Try hold it below 80C.

 

Both GPU and CPU?, during heaven CPU stayed at 50C and GPUs at 85-90C.

 

Yes. 100C is max for Cpu and I think around 90C for graphics. A no go

 

Nvidia go with 83c as their throttle point so obviously below that would be ideal.

 

I've been getting 65-80 C on the CPU and 50-60 C on both GPU while playing GW2. Seems about right I think, but the fans make a lot of noise lol. I'm gonna be trying some other games to see how temperatures behave.

 

Great that you only needed a new fan to get it working again!

You have the luxury to basically have best in class cooling and depending on what you plan to do with your machine you may even look into only using one of the GPU's.

I'd definitely go with different fan- and possibly also throttlestop / MSI Afterburner profiles depending on what you do as the P870TM chassis can be almost silent for everyday tasks like web-browsing or office programs, the cooling is that good.

 

That’s the default temp limit on desktop 1080, on the mobile version it’s already set to the max of 91C.

 

Have you undervolted the GPU’s and undervolted the CPU? is it delidded?


But you should be able to get those temps down drastically especially in a 870 chassis with a vapor chamber.

That is a great setup. You have some tweaking to do in several areas to get full potential though.

If I were you, I would sell of one of the GTX1080’s for $500 used for a quick sale and buy a 9900KS and drop that in place of your 8700K. Then sell the 8700K for $275.

The (2) GTX1080’s are great for benching. Or unless there is a specific single demanding game title you play that can benefit the extra power.

If you are keeping both 1080’s and the 8700K. Then I would look in you optimizing the memory speed, cpu speed, cpu cache speed, undervolting the cpu, and undervolting both gtx1080’s and overclocking the GDDR5X to around 11+GBPS

 

Here’s my run! Single GTX1080

 

How is the contact between the heatsink and the ihs? Some Clevo models suffer a bad fit and cause high temps as a consequence.

 

What was your CPU frequency?, do you use turbo boost or keep it at a static frequency during the benchmark?

 

I don't know how good it is, screws are all the in, but i've noticed a slightly overheating (not always) while doing light stuff like moving files and installing things. I'll order some good thermal paste to see if that's the problem.

 

Sorry to say but that score seems to be a little off with the 8086k being at 5.1 and ATX off.

Are you undervolting the cpu? something is crippling that cpu because the score is as close as mine and you are running at 5.1Ghz and i'm running at 4.7Ghz

Here is the score i got with -0.125mV in my CPU and my gpu slightly overclocked (core: +165mHz and memory +525mHz with modified voltage curve):

 

If you have some cheap paste, do a pea size test and see how well it spreads after installing the heatsink.

I found mine had a bad fit and progressively added shims till I had a near perfect spread and realized ~4.3mm was the optimal height.

Moving files and installing things shouldn't be overheating the CPU.

 

Heaven is almost entirely GPU-bound at those settings, so the CPU makes almost no difference.

 

The minimum can vary a lot, any slight hitch will change the value.

 

Rerun it, min should be around 30fps if it doesn't hiccup.

 

It runs 5.1Ghz day in and day out. It runs 5.1 is locked all the time. Unless I set windows to balanced power mode, then it would idle down when the machine is not under a load.

 

My CPU is not crippled. Yes the cpu is undervolted -0.120V at 5.1Ghz with 4.8Ghz Cache frequency. It maybe hits 68-70C in this easy benchmark.

My 5.1Ghz frequency reflects properly in everything else. R15, R20, or Firestrike.

I think the test is just very GPU limited.

If you really want to race CPU’s turn all of the settings on low and re run unigine haven. I will re run mine when I get home.

 

Yea it’ll microstutter. I dunno why it does this. And it hurts the minimum fps.

 

Could also be vram hitting ECC, caused by a too high of a memory overclock.

 

Heaven stutter resulting in a very low min FPS is normal.

 

I see it in the Farcry 5 in game benchmark too.

I cannot see the stutter in haven, but it’s a latency spike that causes the low min fps. The OP has a 10.5 minimum fps in his haven test too. I dunno what it is about stock settings causes the same thing.

 

It's likely the code streaming in data at that point.

 

I recall that hangup in Heaven happening during the night scene on my 1080 when undervolted. I don't think it hangs any longer after the powermod.

 

Wow man thanks, I did not see this until today.

I haven't removed the LCD cable so I still can't egt into BIOS but I've done some undervolting on the CPU (-120mV) with trottlestop, but havent touched the GPU yet, I recently sold the NvME so It's out of work for a few days until the new NvME arrives.

About the GTX 1080 SLI, do games really get an advantage from it?, I've seen benchmarks and it seems almost only AAA games suport it and I don't need that kind of power on those who support it lol. Would it be a good idea to sell it?

 

Sli is not worth it if you are doing any kind of valuation assessment.

 

I was about to buy the HDD caddies but figured out I'd rather do them myself since they're pretty simple. I took this measurements out of a picture from the manual. If someone could take a HD photo of a hard drive/ssd with the caddy installed I'd be great.

 

Your machine should have come with them.

 

It didn't. It came with the screws but not the caddy.

 

Not in the box? Odd they come with every unit. Ask your reseller.

 

It wasn't new when I got it, so it came witout any accesory, only the power adapters.

 

I guess they lost them then, I'll see if I can fish them out of my box as it has been some time since I owned a 2.5" drive.

 

It came with a M.2 drive installed so I think the original owner didn't have any use for them and lost them.

 

They are in the little bag of accessories you get with a new unit.

 

Finally decided to tear down the laptop to figure out what type of connector the LCD uses, it is 40 pins.

 

I could also finally access the BIOS (had to disconnect the LCD cable so it could output POST through HDMI), this is what it looks like.


I don't think it's prema BIOS.

Here are some more photos of the system.

 

Looks like the standard bios from what I see there. The lack of options or not should make it nice and clear.

 

I’d go for 144HZ 1080P IPS to replace the broken panel. Or better yet maybe even 4K, you might be able to better leverage the SLI GTX1080’s power in some AAA titles with 4K. You can get SLI to perform well in most games, just a little tweaking is needed.

A single GTX1080 heavily overclocked does incredible with 1080P 144HZ.

I ran (2) GTX1080’s in a desktop for about 3-4 months with 4K. I was pretty satisfied with the experience overall.

The games do look stunning in 4K on 17 inches!

 

Its personal preference on resolution vs frame rate, I'll go frame rate.
