Mobile Pascal TDP Tweaker Update and Feedback Thread

Why do he need an inf mod ? He only changed vbios and hardware id cannot be modified with software, all is set by hardware (board + core).

 

Well, he's getting the 43 driver error. What else should he do?
Seems like this guy got some drivers working:

Something I wanna post here when I was trying to upgrade M17x R4,

Neither the GTX 1060 nor GTX 1080 from the ASRock Deskmini work with drivers newer than 378.66, both will throw error 43/black screen.
ASRock cards were those used on industrial PCs, and both have checksum beginning with 9*******, the ordinary 1070/1080 /Quadro P5000/P5200 have 2******* (all except a few found on mini-PCs, e.g. the HP Z VR)
Check your original vBIOS and see if the card was intended for laptop or mini PCs

 

@Liddo-kun Still not working with J95's drivers or with the other link where I put the nv_dispi.inf inside the pre extracted package. Both end up with code 43

 

error 43 means card isn't working, could be anything, from dead core, to corrupted vbios or not compatible vbios etc.

@RMSMajestic
My card is reporting GTX 1080 mobile core hardware ID (1BA0), so that's strange if desktop vbios is needed

 

Exactly, I have modded the tdp of many cards in the past, using maxwell bios tweaker, kepler bios tweaker, the one on this forum for pascal cards. Never EVER encountered an error 43, so this is a vbios limitation or something nvidia have put in place. We may need to change other values also, who knows...

 

Tell me something, the card you received from @Ionising_Radiation was it rtx based mxm?

 

It's very weird how it's working, my P4000 (mxm, in my M6700) can work with desktop vbios and also P5000 vbios, that's very weird, like I flash at first a good working vbios, I install drivers etc, then if I change the vbios it display nothing at first but when windows is booted, it start displaying something and everything works fine

 

All the GTX 1080 cards on mini PCs (ASRock Deskmini, Zotac ZBOX Magnus) have hardware ID as 1BA0, I forced flash it using programmer with that 1BE0 vBIOS and it is working. (There are a lot more 1BE0 vBIOS on TPU than 1BA0).

 

What are you talking about ? I only received 2 quadro RTX vbios from him

 

@TheQuentincc ah ok I thought you had an rtx mxm lol, nvm

 

try driver 378.66, It's from nGreedia. According to our well known member from Canada nGreedia sends out something to cripple DIY every summer

 

Ohh I remember that driver from WAAAYYY back, when the vortex 1070's actually worked without that damn code 43

 

So 378.66 is the newest drivers possible to get the 1080 zotac working ? Even when inf modding a recent drivers, it does not work ?
Did you tried it in the M6700 with the vbios that works in the M17x R4 ?

And did you use Mobile Pascal TDP Tweaker to lower the TDP to 130W ? did it worked ?

 

No, the Zotac 1080 is not bound to this problem. On my side it's only the GTX 1060 from ASRock Deskmini that's having this problem.

Zotac 1080 is working on M17x R4 with typical inf mod to at least driver version 425 with the vBIOS I attached at #2239.

As for M6700, still, physically don't fit.

 

I read too much too quickly, when you said that neither asrock card works with newer drivers I thought you were talking about Zotac magnus card.. but did you tried other vbios on Asrock card ?

And did you use Mobile Pascal TDP Tweaker to lower the TDP to 130W of the vbios you provided ? did it worked ?

 

Or maybe try with some Linux distro to check if the card is actually working or not. The error 43 thing probably doesn't even exist in the linux driver. So that way you could check if it's hardware related or not.

 

Understandable, this is a TL;DR thread afterall and I won't mind making it a bit longer XD
I tried both 1C60 and 1C20 vBIOSes, and all are throwing error 43, as for the ASRock 1080 I can't even find a working vBIOS. (all black screen).
And no, without the header 4E 56 cards simply won't work on M17x R4 (blackscreen and beeps), which is a huge problem cos the working vBIOS I can find now is a 200W nuclear bomb.

 

1C60 and 1C20 vbioses ?

 

Are you running laptop display, or external? Any video if you plug in displayport?
Its certaintly possible the vbios is not working.

What happens if you uninstall the driver, does it try to reinstall? This means at least the device is detecting ..
Man, the shunt mod will be way easier. ever take off the HSF? If I can get a good pic, I can determine the SMD size and order the right parts from digikey. The shunt will literally cost 10 cents. Very easy to reverse.
If the current shunt is 0.008 ohm, Just stack a 0.07 ohm resistor on top and tack it with solder.
I also need to know the SMD size, to order the right size so it fits well. (can determine from pic)

 

I’ll take a detailed picture of the gpu area on the mb

 

Yeah I tried both, 10DE 1C20 is for the GTX 1060 without gsync and 10de 1c60 is for the gsync counterparts

 

If you have calipers or small scale, measure the size of the resistor in millimeters, otherwise, Ill reverse engineer it from the picture.

 

okay, I'm trying the 1080 in the M6700 right now

 

Plz remember to take a video when ur M6700 explodes!

 

@Liddo-kun here is your picture, hopefully it is clear enough...

 

This might be the shunt. Can you take another pic down here.

Edit: nah, thats the battery shunt.

Pretty sure this is the shunt.
https://i.imgur.com/fP0d9Qp.jpg

Do you have a multimeter to verify those two resistors are in parallel?
can you measure their size in mm?

 

I think the shunt are the R005 one next to the mosfet

 

Should I solder across both of them, I’m pissed as it is with this machine

EDIT: the ones next to the mosfet ofc not the one next to the battery connector lol

 

Basically can I get to rtx 2080 mobile levels of performance with a shunt mod plus the +200mhz core overclock and +400mhz on mem? I’m about 10% of it atm.

 

That's a little bit too risky I think, you should use other resistance in parralel, to have ~10% more current/TDP you can solder a 0.047~0.050 ohms resistance on top on both shunt

 

@RMSMajestic do you know if the vbios you provided is UEFI compatible ? there a little case in GPU-Z that confirm it

 

If they are in parallel and I did just put solder on each of them, separately ofc. Would it blow up the mosfets? I’d take the risk if it’s only a 20% chance lol. I got this laptop for literally nothing

 

Im measuring the shunt resistors at 2.85 x 1.6mm

 

Bad idea. Just get the right resistors.

 

@TheQuentincc will an R050 work fine I have one can probably find another...

 

0.036 is better. 14% more power, or 131W..
https://www.digikey.com/product-det...-product/RLP73M2BR036JTD/A109831CT-ND/4032597

 

Req is the formula for parallel resistance, in this exemple by soldering a 0.05 ohm on top the existing one you get 11% more current (= TDP), I'm too tired to explain this properly, there is multiple way to explain this too.


It will be good to know which mosfet do you have

 

Ah I get it now, sorry @TheQuentincc and @Liddo-kun I have never needed to check resistor values lol. I’ll see if I can find that value resistor, got a lot of scrap mxm cards for my spare components

 

already ordered

should be 131W

 

be carefull of mosfet cooling now

 

Would you believe I received this laptop with no thermal pads on anything, no thermal paste on rtx die just some oily fingerprints and seller is telling me it gets too hot and crashes, I’m thinking who tf put the heatsink on with no pads or paste!

Good luck @Liddo-kun

 

I also ordered these
https://www.performance-pcs.com/air...-ultra-thin-heatsink-6-pack-mdy-8810-2mm.html

there is 1.9mm of space between case and heatpipes in max 15.
ill sand the base down by 0.15mm, there's lots of room for a bunch of these, should help alot with cooling with a cooling pad.

 

Nice deal. Ebay ?

 

you know it

 

BTW mosfets can be quite resilient I’ve loaded a Gtx 980m with 200w of power, same with a Gtx 1070 before. Both ran like champs

Obviously both gpus were cooled well, never reached mosfet thermal runway point, imagine that. My card would be dead aswell as the mxm slot temp sensors

 

a card where nvflash can't read the vbios but an external flasher can, what does it mean ? (drivers installed)

 

Yes.... I assume if it's not UEFI compatible then I couldn't have it booted on M17x R4..... Also M17x R4 have better compatibility than M6700 just saying

 

@Rinkutux do you have any flasher available?

I can't seem to find the new bios for this laptop anywhere. Since you are on the same bios all I need is your bios.rom and ec.rom and I can get my laptop gpu functioning normally.

 

My flasher is at home, and I don't know when I'll be able to go there because of that virus thing. Isn't there a software that can extract your bios ?
Maybe we can extract it following this ? https://www.win-raid.com/t4386f16-O...vo-MACHENIKE-Unlocked-BIOS-Guide-W-Files.html
I'm not using Windows right now, so I might try that later
