Mobile Pascal TDP Tweaker Update and Feedback Thread

Artic MX4 2019 edition

 

Can you share what the paste looks like after removal? It will identify if contact looks good.

 

Then it is very odd.
Your heatpipe has not been damaged have they? A wrong bend or small crack will ruin the heat transfer. Remember there is a small amount liquid inside. If there is a bend the water will not be transferred properly, and a crack will make it leak out.
A simple way to test it, is to feel if the temperature is the same in both ends of the heatsink, (without The fan). If it is way hotter on top of the graphics card than at they end then the heatsink is dead.

2. Symptoms

1.if it heats up very slowly on the entire heatsink, then it means the water is gone at the heat has to transfer through the metal.

2. If you feel along the heat pipes and there suddenly is a spot where the temperature has a drastic change, then it means the water is not traveling any further.

 

I have flashed a new system Bios for Alienware 13 r3 1.7.0. just now (from Windows), and it has no problem/conflict with previously (3 months ago) programmer-flashed Vbios 110-130W for GTX1060.
Games still pull higher than 72W (default), in my case spiking to max. 105W at 1898Mhz/0.912V/+350 mem.

 

I come to thank the community, since it has been very easy to modify the vbios and begin to enjoy this additional power.

In case I can help the community, my laptop is the MSI GT72VR 7RE, it has a GTX1070.

The watts used in my modified vbios are between 151-170 and I have been able to control the temperatures using liquid metal. In games such as Battlefield 5, temperatures do not rise to 71ºC and maintain FPS with ULTRA configuration between 60-80 with DX11.

The result of my laptop with 1070 after using the modified vbios


Greetings to all!

 

do u also have a "before" screenshot/score for comparison?

Sorry, I cannot find the previous captures because I've been deleting them as I got the advances. I remember that the results barely exceeded 3800 after applying OC to the FSB bus and configuring the performance options in the NVIDIA panel.

Here are the results of an identical PC:

I tested it, and the heatsink is still Ok.

I repasted it nicely applying a thin layer in almost the full size of the chip, just enough to avoid the paste to run into the print circuit

 

That tape wont completely stop run off, a foam barrier would be the final barrier.

 

Finally I found a way to change the power limits of the mobile GTX 1050 Ti. It turned out to be harder than I thought. Power limits in VBIOS aren't explicitly indicated unlike GTX1060/1070 and desktop 1050Ti.
1. Original VBIOS, default MSI AB curve

2. Mod VBIOS, default MSI AB curve

I will describe modification process in the future. So far I don’t quite understand what mean some of the values I have changed.

Hi, does it work on Quadro P4000 mxm 3.0b ?
Thanks

 

is it possible to flash a vBIOS of a desktop GPU on a laptop GPU from the same manufacturer?

I have an Aorus X5 V6 and I think my vBIOS is corrupted. Whenever I install my GPU driver the screen flickers with the color of the theme on windows and it goes blank.

I have to power cycle and then uninstall the GPU drivers to get the system to work.

System works fine with anything, even extreme CPU overclocks but cannot even handle windows when the GPU is enabled.

Any suggestions?

 

No. Flash a copy of the stock vbios. If that doesn't work, RMA, it may be a hardware failure

 

Desktop vbios has no idea about eDP for example. It's like asking if you can flash a desktop motherboard bios onto a notebook.

 

Does anyone have an Aorus X5 V6?

Also, can I flash the vBIOS of a laptop of the same specifications?

 

Check over at the Gigabyte section.

 

There is a slight version mismatch on nvflash and wants to reconfirm whether I want to flash it.

Should I flash it?

 

If you have a way to recover it, otherwise you could brick it.

 

I have saved a copy of the current firmware on all my drives.
Assuming I brick it, is it a soft brick or a hard brick?
Would a re-flash it away?

 

Assume if it's bricked you are going to need a clip on programmer to recover it.

 

If the laptop still boots then you could do q reflash with your original vbios dump. Otherwise you need a harfwareflasher or maybe you could reflash it with a dos usb stick with nvflash and your original vbios on it and you know the procedure without any visual help ;-)

Correct me if i'm wrong:
Is there no way of doing a "blind" flash with a dos usb stick and nvflash on it?

Gesendet von meinem SM-G973F mit Tapatalk

 

Before I brick it, is it possible to analyse the current vBIOS that I have to see whether the current one is corrupt or has bad sectors?

 

I believe that we can use the command prompt option is the f9 menu that comes up. the one for system recovery?

 

Hash check it against a known good file.

Depends on what you've done to the firmware and if the machine will boot in the compromised state.

 

Really don't know. That was just an assumption that it could be possible. But for that the notebook needs to pass the bios check that you can choose the boot device.

Sort of new to this, so if you don't mind me asking, how do I hash check the file?

Have a read up, generally flashing an integrated Vbios onto a board which has not been tested is not recommended for beginners.

 

To flash a 1070 (laptop) bios over a Max-Q version, do I need normal nvflash or with Board Id Mismatch Disabled?
If I dump my own vbios, and modify it with the tools to the same values from a normal (laptop) 1070, would it have the same effect as flashing the normal 1070 bios?

 

Kinda but not really, and it's not recommended as you could end up frying the boards power delivery system, or it wont work at all, because most of the time, that is controlled by the actual boards power control subsytem

But seems its controlable with undervolt:

Again I didn't say it was not doable I was just stating as above that the motherboard may have its own limits too

I flashed it but to no avail. It did not fix the problem. Thanks for the guidance though.

 

any hope for nvflash with bypass cert which will allow flashing modded vbios for Pascal?

 

nope. Even programmers aren't working for Turing cards.

 

we can't read and write the eeprom ?

Also, I would like to know if any of you got any of these missing picture in this thread ?

Hey, I have been trying to read this thread, but the information seems to have accumulated, its a little overwhelming.

I am contemplating editing the vBIOS of my GE75 RTX2070 laptop, to a TDP of lets say 150W, since this same model comes with the 2080 card which is a 150W card, I assume the internals are going to handle 150W.

I have downloaded both the tool here, GPUz, extracted my vBIOS, made backups, and edited via the editor here, to target/limit 150/150. I am thinking the next step is to use NvFlash since it supposedly supports turing GPU.

Is this all correct? Or must I have a physical programmer? If the BIOS doesnt work, can I flash it with the original using NvFlash, or is there any chance (slightest) that my computer will not boot into windows.

Edit: Also in the editor, I am able to edit the power settings, however it says "Unsupported" in the BIOS name and Model rows. Could this pose a problem?

As far as I can tell, Nvidia applied a digital signature to pascal and beyond, but since the 10 series cards were able to be flashed, does that mean this editor has a work around?

 

Thanks you a lot, I managed to find core clock (base, boost & co, no unlock it seems), core voltage (I will not touch this now), tdp (unlock and value), temp (unlock and value) but I couldn't find where is located memory frequency on my vbios, can someone have a look on it ? I tried to find idle memory clock (+/- 1 MHz), "boost" memory clock (+/- 1 MHz) but I found nothing (at least "boost" and idle freq were not followed)
So far this is what I found (attached picture), I will try modded vbios later this week

edit because of error in "tdp value"

 

Turing modding is not supported yet. Bios support is experimental. The developer does not even have a turing laptop card afaik. The source code I believe is available (or supposed to be available) so another person who knows how to mod and bypass the checksum problem can update the program.
NVflash will not flash ANY modded vbios without a valid certificate, pascal or turing or anything else. A HWprogrammer can flash anything but a turing mod or an improperly done Pascal mod will not POST and you will have to force flash the backup you so wisely created, with the same programmer.

 

Thank you for this info. It is a shame they made this so difficult, because this cards 115W limit is plain stupid.. It barely spins the fans and the laptop has plenty power spare.. I guess they do this to justify the 2080 model.. I shall keep my eyes open for a more experienced users experience flashing an RTX laptop with a programmer. Maybe do that in the future. Thank you for the info!

 

Hi, I modified my P4000 vbios "by hand" (=hex tool), I flashed the bios multiple time, verify multiple time and event tried disconnected and reconnected the "probe" to see if it is still ok, and it was still ok.
The thing is, when I boot on windows (optimus situation) it tell me that the card is in error 43, I tried to get the same checksum than the original/working vbios (by using mobile pascal vbios tweaker) and it still stuck at error 43.
What I did wrong ? it might the checksum not valid because MPBT doesn't support my card ? If so, how to know where is located my checksum ?
Thanks a lot

 

Howdy guys, I have a bit of a wildcard I'm hoping someone might be able to assist with.

Long story short, got the programmer, took the machine apart, hooked it up correctly, backed up the original bios from the chip. All good.
Pulled the backup I made into the TDP tweaker and made minor adjustments. (Made a second modified version with the "preset" settings as well.
So, I have the original, one with higher TDP limits and the final with the preset.
Go to flash (blank chip, verify blanked (OK), then write and verify the modified bios file. Put together, start > Black screen.
Go to flash (blank chip, verify blanked (OK), then write and verify the SECOND modified bios file. Put together, start > Black screen.
Getting nervous I now have a 14lb brick I went back and flashed the backup that was untouched. Put together, start > Boots Fine.

So moral of the story, any of the modified bios files I've made seem to brick the card, but the backup works fine.
Am I missing something here? I checked the bios checksum and verified they are all matching.
I'm not quite sure what to do at this point, so if someone could help me, or at least point me into the right direction I would greatly appreciate it.

I've attached the three bios's that I flashed, again, all fail except the backup for some reason.

 

What notebook are you using?

Gesendet von meinem SM-G973F mit Tapatalk

 

It's a P870DM2, the one in my sig. The card is a GTX 1080.

 

Have a check to see what your BIOS starts with bud in terms of hex if offset (h) starts with "4E 56" and Not "55 AA" i had the same issue before where it wasn't clearing everything from 4E56 to 55AA..

I noticed this as when i modded the spare backup file on mine it would loose 2kb in file size and when i looked into it the original tool wasn't removing 4E56 to 55AA which was giving me Blackscreen however if the section 4E56 to 55AA was removed the blank screen issue was fixed. Might be a good place to start.

Also might be a good idea to give coolane a buzz with your firmware dumps as well.

 

Thank you for that response! So you're saying everything between 4E56 to 55AA needs to be removed?
Both of the BIOS files appear to be showing the same values as far as the 4E56 are concerned.



If anyone just wants to "Unlock" the TDP in the backup (known working file) below, so I can see if it's something on my end that's wonky I'd appreciate it.
As long as I have the capacity to control the TDP and the limit is around ~250W, I suppose the hard coded values don't matter. I'd just like to get rid of the TDP throttling at ~1950+ Mhz.

Thanks!

 

Will see which version has the blackscreen fix for you

Sent from my SNE-LX1 using Tapatalk

You should use the Mobile Pascal TDP Tweaker v1.1.1.0 version. this removes the 4E 56 area so it starts at 55 AA to see if that works.


Edit: Got wrong Values lol. Still good work,

don't use the file i put up though i put 280w in instead of 258w like a muppet.

 

Thank you so much!

So you're saying it should look this one (left). I just loaded the preset config on the known working backup (right).

 

Yes, just bare in mind your system might display the Device ID with 0000 0000 at the end and your going to need to mod the inf files for that adjustment.
