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

barely any aside from being in a laptop would be heat, which reduces frequency, though i'd take 8 core and disable HT still better than 6c/12t anyday, while heat should be in similar league.

unless this 8 core is not on the ring bus design and is on mesh, that would be terrible given mesh got latency problem if we can't overclock it past 4000mhz

 

As you add cores for the same power your per thread performance drops.

 

by a tiny bit tho, well i guess that would also dependent on the software and cpu design. have you tested CB15 ST on a fixed single core, VS CB15 ST test but not fixed on 1 core.

result is performance is greater when its not fixed to 1 core, either its because ringbus design or if that core happen to be further away from the IMC has higher latency, or just how software is.

 

Anyone here using static voltage on the 8700K? I'm curious what your V is set to?

I currently don't have my laptop as it was sent to HIDevolution for warranty repair, but I read that 4.8GHz all core should average at around 1.2V to 1.3V.

The OC thread contains a discussion about some AC/DC setting in the BIOS which seems related and interesting - sadly I don't have my laptop right now to play with.

 

4.8ghz at around 1.2-1.3v is for desktop class cooling or watercooling, with a delid. 870TM heatsink is junky and small so it brings up overall internal core temp thus requires more voltage. however afaik those value don't show as pure static. meaning if its load voltage it could be adaptive while idle voltage remains high.

mine is a 5.2ghz sample from SL and at 4.7 I am at 1.24v for static, including AVX workload. without AVX it can probably go lower if its just tests like CB15.

 

The impact is felt even on the high end desktop platform where power limits can be even higher.

 

Guys do you hear eco sound. When hear any music its sound like I'm sitting in empty room. Is there any settings in drivers or sound blaster?

In the sound blaster app you need to look for the "reverb" digital dials. I think it's in 2 places. Drop them down to 0 and the echo goes away.

Edit: Here's where I found them on my system

 

Thanks man. Setting were two places, in sound tab I did but I never maximise the dashboard so the reverb always hidden from eye.

It does seem to auto enable when installed.

 

Any updates on the benchmarks and temperatures of the 8086k in the P870TM?

 

Stock is pretty much the same as the 8700k, it comes down to tweaking if you want the advantages of a well binned chip.

 

@Meaker@Sager @Donald@HIDevolution m.2 SSDs running a bit hot cause i disable ASPM or LSPM etc for PCIE/chipset for extra performance.

any idea how thick of the thermal pads required for those SSD to transfer heat into keyboard/chassis?

 

2mm soft ones would likely do it but that's just a guess.

 

That would be my guess too. The only way to really know is to experiment.

 

the p775tm dissipators do not fit the p775dm3g? are you sure? has it been tested? I know that the motherboards are different but the position of gpu and cpu as well as the screw connections seems to be identical from the photos ..... I wanted to buy the sink of the p775tm but I wanted to be sure it fits.

 

Well I'm finally using the P870TM1 as my main laptop. Swaped the crappy 3K G-Sync display for the 1080p/144Hz display (provided for HID for free). To new buyers, if you're going to playing games most of the time in this laptop, please just take the 1080p/144Hz screen. Let's just say that there is absolutely no benefit for a 3K resolution on a 17 inch screen over a 1080p resolution. Even worst, you have to deal with the awful Windows 10 scalling and your games will run slower. Honestly I see no difference on a game running at 4K or 1080p on a 17 inch screen.

Being said that, I'm impressed with the performance of the laptop, I got a huge improvement on my frames per second compared to the AW18 W/GTX 980M, I'm pretty happy with it

The thing that bugs me is that the settings on CPU voltage offset or max multiplier won't stay on BIOS. The voltage offset always go back to zero after a restart and the max multiplier goes back to x47. why is that?

 

I'll answer to myself. ThrottleStop does the job. The OC app from the CCC is kinda broken, it's just not capable of keeping the settings after a system restart.

Other question. What are the temps you're getting in CPU and at what clock speed per core?

 

Hello,

I'm looking to maybe purchase a P870TM here hopefully within the next month. Is anyone here selling one perhaps? I'm pretty torn if I should go the barebones route via rjtech.com as it's pretty easy to source good hardware prices on eBay and Newegg. I've also been looking into hidevoloutions with the exception of their prices when it comes to SLI options builds strictly for the Premabios and a delided processor.

 

If you are going to purchase this beast, it's practically a requirement to get the Prema bios on it to get the most out of it so definitely choose a Prema partner. https://premamod.com/partner/. Also, if you are looking at SLI (meh), www.HIDevolution.com offers the dual vapor chamber mod which is worth its weight in gold for cooling purposes.

 

Every 1080 SLI setup comes with the vapor chamber cooler.

 

Well if you buy 1080 it will come by default though

Either way, the vapor chamber is frickin awesome.

 

The Vapor Chamber is indeed awesome.

It comes standard when you get Dual GPU’s in SLi, and is an available option when you get a single GPU.

 

Thanks for the feedback. I'm pretty deadset on wanting to get it when I'm able to. Probably from HID

 

That it is It's really interesting to see how it has evolved over time too.

 

they need that for cpu heatsink, or rather, they just need a bigger heatsink for capacity, not vapor is fine too.

 

Or hook up a 4th fan in there. Anything to drop temps while overclocking.

 

from my tests of adding 4th fan, it does little. especially if you want a quiet laptop on auto fan profile then the only thing that can help here is bigger capacity.

increase the capacity for a 4 major (not tiny) fan would help for sure.

 

Ductwork and dry ice, lol. I've run 2 large fans under it and it only knocks a few degrees off so I tend to agree with you that a larger heatsink and/or larger inside fans would be great.

 

Why couldn't they use a vapor chamber for the p775TM1?

 

They cheaped out lol

 

Cost Vs benefit on such a model, you would still want some more fin space to take advantage.

 

Yea tell me about it

It would've benefited us that are using the P775TM1 especially with 8700K and 1080 i would think. I feel the current heatsinks are not enough.

 

I disagree, the cooling on P7XX is not nearly enough for a 8700K + 1080, especially if the paste job is not absolutely perfect. Sure maybe some companies can pull it off, but this is a Clevo issue, they should not cheap out on materials and what they're doing for any model.

Yes, this is what I noticed before I sold my P775DM3-G, 6700K + 1080 were both overhewating badly, and the company who made it for me screwed the screws too tight so I couldn't unscrew them anymore. I trust some other companies can do a really good job, like Obsidian, HID and Sager, no bad talking about them, just, Clevo should probably consider improving the thermals for everyone where possible

 

But at what cost?

 

Some of us want a portable system that has desktop parts. The P870TM is not really as portable as the P775TM is. I'm sure im not the only one that feels this way.

 

I almost bought the P870TM, but then i looked at the size and realized it was not as portable as the P775TM.

 

this probably not just for p870tm but for other laptops as well, google will show other bunch of results.
anyone having this computer torrent and BSOD with tcpip error? this only happens when torrent on wifi, with specific intel's wifi card i'd assume its driver issue.

at first i thought its my overclocking that idle voltage peaked too high causing this but once set to ac/dc = 1 it's still crashing. doesn't crash when using ethernet nor USB wifi adapter with torrent..

 

You and I are in the same boat mate.

If anything undervolting both CPU and GPU plus running the P775TM on a cooling pad help massively, granted that it's currently winter down here so sub-20C ambient temp is perfect. I spent couple of hours on BF1 last night and max temp was 79C on the GTX 1080 with "Optimal settings" in Nvidia GFE (a lot of Ultras).

 

D!tto

 

As time goes on they hopefully become more ubiquitous.

 

or they could give us 4 giant, thicker fans and bigger heatsink like MSI in a newly designed laptop that house 8 cores.

 

The np9877 is already the size limit you will see most likely, it already cools better than the MSI.

 

Given the same configuration but for the CPU (BGA vs. delidded, undervolted and overclocked LGA), including the Grizzly Conductonaut + Fujipoly Extreme Thermal Pads upgrade, and a proper undervolt, the MSI GT75 runs about 10C cooler than the EVOC High Performance Systems P870TM1.

 

I was more thinking sli 1080 Vs gt8x since he was talking a 4 fan beast. What specs and clocks are you looking at Donald?

 

On the EVOC High Performance Systems P870TM1 it would be the Intel® Core™ i7-8700K OC'd to 4.8GHz, locked on all 6 cores, or the Intel® Core™ i7-8086K OC'd to 5.0GHz locked on all 6 Cores using the Custom Prema BIOS.

 

Just on the CPU side @Donald@HIDevolution or are you seeing that differential on the GPU too? What clocks are the gt75 running?

 

I'm curious as well about that. 10C on both GPU and CPU is interesting but we're talking i7-8700K vs i7-8750H right?

 

MSI GT75 8RG TITAN-094 w/ Intel® Core™ i9-8950HK, stock clocks, -80 mV, with our BIOS mod, GPU is about the same, in the mid-70s. CPU runs about 8-10C cooler.
