For me it looks that the panel is failing... good thing that the panel is not an expensive thing to be replaced

 

Not too difficult either.

 

I've done a bit of reading on the matter, and it does seem like swapping the panel shouldn't be a problem. If I'm reading the user manual right, I need an LP173WF4 SPF2 panel. Do I still have to use an exact replacement if I want to maintain G-Sync functionality, or has anything changed with newer nVidia drivers and "G-Sync compatible" displays?

As an aside, how common is it for display panels to fail for no apparent reason? I'm asking because I try to be careful with my electronics. If I take the laptop with me, I always use an Everki Titan backpack. When I travel by car, it sits upright on the back seat, with the seatbelt on. I basically treat it like a baby, which is why I've been racking my brain for the past few days trying to remember if anything I did could have caused this. Apart from bumpy roads, the only thing that came to mind was that I left the backpack leaning screen-side against a wall for a few days, which could mean that there was some pressure against the lid. It doesn't really make sense with the amount of padding that backpack has, but it's the only thing I could come up with, and it's frustrating. I've seen work laptops where the lid flexed enough for the anti-glare film to scrape away against the keyboard and trackpad with no damage to the panel itself.

 

Same rules on panels and g-sync.

 

Hi everyone!

I have a sound issue. My sound is popping each time my card power on.
I read it could be because Realtek powermanager is set into my computer, or because i use IRST.
I checked in Regedit to find the Realtek Power manager key, but i found nothing.
I uninstalled IRST but it fixed nothing.

Someone knows how to fix it?

I keep searching.

 

Did you disable the Realtek Power Management? Open the realteak audio settings windows, click the "battery" icon and disable power management.

 

Hi John,

I know what you mean, but since I update with driver 84** and now 85** I haven't anymore that option, and i haven't the realtek panel. Then I should have some keys here (HKEY_LOCAL_MACHINE\SOFTWARE\Realtek) that manage my sound power, but nothing in my computer.

Edit : I found the Regedit key! Here: HKEY_CURRENT_USER\SOFTWARE\Realtek\Audio\RtkAudUService\

 

I delete all the keys in regedit, because I don't want popping on battery or powering off.
I restarted, then all is working nicely!

 

Great job!

 

Anyone know what VBIOS is needed to get a Clevo GTX 1080 working in a P750DM2-G? Mine is from HIDevolution so it's got Prema BIOS on it, if that matters. Edit: I'm assuming 86.04.2A.00.2B (G-SYNC, no SLI) is the correct version. Will 86.04.00.2D (G-SYNC, SLI) work as well, or should I hardware flash before even trying?

 

I asked to my seller about that some months ago.
To work you should get a UEFI (not Vbios) able to run the card. I don't know if Clevo made it.
I run a Prema Uefi. You can only get it from a partner by buying a new computer from this partner. There are no UEFI updates for Prema according to my seller.

 

I'm trying to remember the cut off point but go with the older one.

 

HIDevolution is a Prema partner, thus I have Prema’s BIOS (as stated clearly in my post).

I was under the impression that the .2D one was for SLI+G-SYNC and the .2B one was for non-SLI+G-SYNC

 

Sorry I read wrong this morning (Just before my coffee)
If you find a way to run a GTX1080 or RTX in a P750DM2-G i'm interested.
Eurocom said to me "no way, you need a new UEFI that not exist for your laptop".

 

There is also a pre tm vbios and a post tm vbios where the structure changed. You need the pre tm vbios.

 

I assume you are referring to 'tm' as in P7xxTM-G, which are Coffee Lake/Coffee Lake Refresh. From what I understand, Coffee Lake + requires VBIOS UEFI GOP version 0x30006 or later, dated Oct 26, 2016 (refer to http://forum.notebookreview.com/thr...clevo-laptops-rtx-cards-now-supported.825558/)

I downloaded the VBIOS @Mr. Fox shared here http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-722#post-10406952 and checked it with nvflash --version and found it is 86.04.2A.00.2D with VBIOS UEFI GOP version 0x30002 dated Apr 1 2016.

Additionally, I downloaded the VBIOS as posted here https://www.techpowerup.com/vgabios/186530/clevo-gtx1080mobile-8192-160706 which is "verified" and claims to be a Clevo GTX 1080 and it is 86.04.2A.00.2B with VBIOS UEFI GOP version 0x30002 dated Apr 1 2016.

Lastly, I dumped the GTX 1070 VBIOS off my current card and found it came with 86.04.2A.00.27 and VBIOS UEFI GOP version 0x30002 dated Apr 1 2016.

Given this, I think I should be good to flash either @Mr. Fox or the one from TechPowerUp, considering they both have the old UEFI GOP version 0x30002 dated Apr 1 2016.

 

Correct, that should work.

 

Hi Guys,
A guy bought a clevo 751tm1 w/ a 1060, but the card does not go above 75W. It has a general 88W vbios, but no matter what if never breaks 75w. I used to have a 775dm3 with a 1060gtx, it went with around 90W, with unlocked vbios even at 150W. What could be the reason that in the 751tm1 it limits itself at 75w? Something can be done? thx

 

Is it an original 1060? Have you checked the thermal pads?

 

Yes, original eurocom 1060, thermal pads ok. the card does not pass 75w

 

Maybe a phase has failed? Odd.

 

How can i check? Thx

 

It's tricky, a thermal camera would do it.

 

Cheaper is with a coil and a LED, in both cases you have to do it without the heatsink.

 

Also worth just physically inspecting it all.

 

About conversation on Vbios.

What is the difference between desktop GTX1070/1080 Vbios and mobile one?
To flash a new Vbios, do we have to use an external bios programmer or can we do that through a software?
If I understand, flashing a GTX1080 allow to use it into the P750DM2-G.

 

Good news, installed the GTX 1080 into my P750DM2-G and it worked straight away! I lost G-SYNC but that's minor.

It originally had 86.04.56.00.2A with UEFI GOP version 0x30006, and was recognized by the BIOS and in Windows. I flashed 86.04.2A.00.2B with UEFI GOP version 0x30002 anyways.

One thing to note. Drivers installed fine under Windows 10 but I was not able to get drivers to load under Windows 7. Not sure why. PCI Hardware ID is VEN_10DE&DEV_1BE0&SUBSYS_75071558&REV_A1 any suggestions?

 

Different firmware and difference between brands due to the more complicated setup. They can be flashed in place.

 

Got it to work. I had to edit nvcvi.inf and change "VEN_10DE&DEV_1BE0&SUBSYS_77081558" to "VEN_10DE&DEV_1BE0&SUBSYS_75071558"

I regenerated a cat file with inf2cat and then used signtool to sign and timestamp the cat. Installed drivers regularly through the Nvidia setup and they work flawlessly.

 

Guys. Is it safe to apply thermal paste on gpu and cpu if on the copper heatsink of a laptop there is dried liquid metal that is hard to remove? Wont it cause issues?

 

No, it wont cause any issues. It's not technically ideal thermally but such a thin layer should not make much of a difference.

 

I think it's better to remove it before. I would do that.

Question for you guys.

I read some stuff about C-state Auto Demotion, C-state Un-demotion, Package Auto Demotion and Package Un-demotion.
My goal is to increase (as well as possible) my battery life.

I understood that options (I guess).
My question is, do C-state Auto Demotion can be set to C1&C3 and Un-demotion set to C1&C3 too?
For me Un-demotion is the opposite to Demotion. Is it not?
Do Package Demotion can be set to Enabled and Un-demotion to Enabled too?

 

Usually the defaults are going to be tuned to allow the CPU to best clock for efficiency.

 

I tried (I'm curious) but it did nothing more.
I let it by default.

 

No magic bullet for better battery life I'm afraid, the gpu and GDDR staying active see to that.

 

I think that I might still want to activate the iGPU on the p751DM.
Time to find a motherboard and begin modding it, to be able to use it with and without the MXM card.

 

There is no power circuitry on the board, how would you route to the socket pins?

 

There is power circuitry for iGPU on the P7xx-DM models.
About routing to eDP to be able to display from iGPU, it's a big question. Maybe using a mux for this would fit, but I wonder how the BIOS setting works for the display options, does this control some pins on PCH or IO controller...

 

Where are you seeing it?

 

In schematics and on the board.

 

Can you circle the phases on a shot of the motherboard?

 

And somewhere to 100 other SMD components on the CPU power controller IC.

A word with some clevo engineers might help, for instance if adding everything on the board, the iGPU will work as usually does on PC, or somehow different.

 

Yeah you wont be powering much with unpopulated phases. Plus if you use that schematic to trace the video out, where does it go?

 

On schematics video goes nowhere, the eDP works directly from MXM. Why clevo would make iGPU power circuitry but nothing about video signals?

 

Save on costs and complexity. In same way as Clevo added a 4th fan header on MB for the P870TM, but in the end the engineers skipped the 4ht fan

 

The only way to make it work somehow, is to use a MUX for switching between MXM and iGPU video source, and make some BIOS tweak to be able to choose between these 2 and make by default the iGPU as primary video.
I am not sure how it works in W650k model, it seems that in that model its done a kind of optimus?

edit: main difference is that w650k uses a H170 PCH

 

There is a mux chip the can redirect the video connection on boot in models that can output from both.

Likely considering if the video transcode of the igp was a feature worth keeping.

 

Too bad eDP is not able to work in hotplug mode.

 

Not usually a requirement of embedded devices

Plus it would still need something to switch over the wiring effectively to the other output.

 

I would like to believe that the "new" 1070 die will live a long live on the modded MXM card i am doing right now, but since I could not make the GPU be even enough, it having a high degree of convexity, i thinl it will not have a very long life like this.
The times when kepler/maxwell GPUs were very even, those were with a higher degree of quality, and, even after several swaps, those kept almost perfect eveness which I have not met on any new pascal cards yet. So I am still looking for an alternative of having iGPU just in case.
