*** Official Clevo P870TM-R Owner's Lounge - Phoenix 5 ***

I'd say those mods need to be a requisite prior to doing a shunt mod, the card and power delivery is going to run way hotter than stock. So for terms of safety and longevity you need to make sure everything is cooled as much as possible.

 

I hope we can get the upcoming 3080 MXM to work in the P870TM1, with a touch of Prema magic and some elbow grease.

 

Should be an interesting performer.

 

The node shrink paired with the vapor chamber has my hopes up.

 

The shrink is huge, they have been on the same process almost as long as intel it seems.

 

I would be a fun upgrade, going from 1080 to 3080, since 9900Kx at 5Ghz is plenty. I only wonder if x8 pci-e might be close to reaching bandwidth limit then.

 

I doubt it will be much of a factor.

 

The Alienware’s also have x8 pci-e as max due the GA. I can’t see this will be a bottleneck.

 

Now we play the waiting game.

 

Pretty much.

 

How much power do your two power modded 1080s pull from the wall?

 

Nothing too extreme usually due to voltage limits but 500Wish.

 

Even with 1.063v my single card at 2050Mhz (daily oc), saturates the vapor chamber to 56c after a gaming session. How does the vapor chamber handle two power modded 1080s?

 

Obviously hotter but it keeps up with gaming at a bit over 2Ghz core just fine.

 

Well that's a given, but still staying above >2Ghz is nice. Do you lock voltages or allow them to run up to 1.063v?

 

They are not the best samples so voltage is unrestricted.

 

I feel you, my core maxes out at 2088Mhz for 3DMark, usually I run it 2050Mhz for daily stuff, memory is golden though.

 

Memory is not great for me either sadly but they have been soldiering on nicely since I got them so I cant complain too much.

 

Were the VRMs on the P870 doubled 8x40A?

 

For the CPU? 4 phase with two 40a I think.

 

Yes, I was trying to find some specs on the 4+1 and the actual mosfets.

 

I would have to look up the chip codes again.

 

It's all right, the VRMs seem plenty capable if they stay within reasonable temps and not lose efficiency too much.

 

Are the mxm slots similar among the p870 dm2/3, km and Tm?

 

They are all x8, AFAIK. Unless that's not what you meant.

 

I think that's the answer I'm looking for as I'm curious about the 3xxx gpu will fit in older models if Clevo doesn't change its mxm form.

 

Hopefully the MXM factor remains the same, since that will leave modding heatsink and bios. Perhaps brother Prema will breathe new life into P870

 

It all depends on the shape and pin out.

 

Finally installed my BartX 9900k P0 into my P870TM1 (now that all my other laptop/desktop repairs are out of the way).

Stock settings, it is running much cooler (understatement) than before (where it was running stock IHS and no shim), but still was getting too loud for my sanity.

My criteria was fans at none to low and seeing if I could get a complete run @ 4.5 AVX 0 in CB20 with no power or thermal throttle

I ended up spending the evening find lows, package pulls and bork points.

Override setting correlated directly with my EVGA FTW Z390 @ 4.5 AVX 0, as 1.075v was as low as I could set it on both before CB20 gave up the ghost.
AC/DC max low was 115. @110, CB20 just exits.
I set PL1/2 to 250000 since it pulled what it needed. At stock 120000, it was power throttling.
I played around with VR A a bit, but it didn't change much.

I managed to reduce total pull to ~127w (from a high of 148w). Still doesn't match my desktop ~110-113w but it is much quieter now almost to 8086k @ 4.8 levels
and when using normally (web surfing, etc..) it is whisper quiet. After establishing bottom pull, I'll end reversing course to push as high as possible.

These are some of the data points I jotted down while testing:




Let me know if something stands out or to try @jc_denton

 

So you are snugging it in at 130W for the balance point.

 

Btw, there is a limit to what card some of the machines will accept, ie DM etc. I'm not entirely sure on the rest but might be worth to look into.

That looks good, the reduction from 148W down to 127W is a noticeable gain! Its harder to get same efficiency, both due to VRMs and power leakage. Especially, when temps go north of 85c.
If you could keep it cool and test same settings, I bet you will be closer to 115-120W
I tested the AC/DC down to 60, but when you go down in LL, the override voltage needs to be upped as you might have noticed. Gains from 210>160 are quite noticeable, while 160>60 were within error (1-2c). Be sure to max out the amps so no power throttling is happening.

 

I’ve been holding at the ~127w point all day for work and it has been near dead silent so I'm happy with that. I'll end up trying to fine tune it and dial it in over the rest of this week.

I agree, it starts right around ~119-120w but as the heat and leak creeps in, it settles around 127w (~1.5w per 10f temp increase).

And I will end up trying some break points since I found my bottom AC/DC @ 115 when voltage is at its bottom 1075mv. I'll up the voltage and decrease AC/DC but I'm not expecting much (140->115 netted zero when in conjunction to a lower PL1/2 and power throttle) as ~120w is getting right in the neighborhood of desktop ~110-113w. I was pleased the same bottom voltage setting on my desktop translated almost exactly to my laptop. It added a little (just a little lol) validity to my previous testing methodology trying to fish for a low voltage able chip.

If you look at my snazzy chart (lol), you will see I switched to adaptive with AC/DC set low just to see and, yeah, right back to 148w, so it will be trial and error to establish if there is an existing break point for lower AC/DC and higher override voltage to chop off some more watts.

I'll dial it in over the rest of this week.

Then I will pick up a license for obsidian fan control to dial in the fan curves exactly.

Installing a secondary CPU fan may allow cooler running at the same or slightly higher speeds (as long as the secondary fan isn't louder than the primary fan on low).

 

Not sure what's up. I don't use the tool

The secondary fan is loud generally from what I have heard, smaller fans have to spin faster to get airflow.

 

Remember to go by temperatures and not watts and VID, as they change due to AC/DC loadline. Brother @Falkentyne did a solid write up about this earlier in the thread.

 

Is it the following write up that you refer to?

It's the pitch that makes it stand out, as you pointed out before.

 

I kinda bet they intended the 2nd CPU fan to be one from their former laptops, like old unsold stock.

 

Unlikely, a good stock of replacement fans is always good and it would not be that much over usually.

 

Didn't even think of that when I was searching for a 2nd cpu fan. I might have to relook at this from that angle and see if anything from an existing Clevo is a better fit.

 

Think the VRM radiator width was ~55-60mm, so a 5v fan around that if you happen to find it.

 

Just a PSA for those who might be googling an answer to installing Nvidia drivers on the clevo p870 with rtx 2080 or similar, as I was a day or two ago: the modded .inf file you can pick up from laptopvideo2go.com needs to be renamed nvcvi.inf to replace the one in the Display.Driver.
If you already knew this then carry on, and if this information seems useful to you but you dont really understand I suggest you do some reading on laptopvideo2go. Oh and you'll need to be a member to download the .inf file....and dont forget to disable driver signature beforehand.

That is all...

 

Same goes for the super variants, and likely 30x0. Hopefully they will use the same powercable and will be moddable this way.

 

If they stick with the same (or similar) form factor and cable reducing installation to just a few potential dremel mods on the heatsink, that would be insane.

The fact they kept the same form factor on the X170SM-G and that's their most likely future design bodes well.

The early numbers and scores for the 3070 also bodes well for future mobile Ampere cards.

 

We will have to see what the configs are like, memory type changes and bit width changes can really cause differences.

 

The 3070 with 256-bit G6 memory are none of those things though.

 

Hey guys, can someone please share a photo of modded vapor chamber heatsink for p870tm, modded for rtx2080?

Which part do I need to cut out? Any recommendations which tools to use?

 

Better chance then

 

Do you know something we don’t?
