GTX 1070 MXM 1BA1 1BE1 switch possible?

Hello guys,
I have a GT72VR 6RE with G-sync MSI Laptop. Sadly the GPU is partially dead (artefacts all over the screen, crashes, windows detecting a damaged hardware etc...).

So I bought an other GTX1070 MXM on ebay, which was used in a Vorter G65 6RE before.
Sadly, when I plug the new GPU in the laptop, the laptop screen stays completly off, but i can use the HDMI port. So i though that I would just have to flash the vbios to the one I was using on the GPU that died, but I couldn't because of a mismatch betwen the PCI Device ID.
The new GPU ID is : 10DE 1BA1 - 1462 11AF and the previous GPU ID was :10DE 1BE1 - 1462 11AF
Pretty close right? but the A1 and E1 variation are fcking everything up. I've read that 1BA1 is for non G-sync and 1BE1 is for G-sync. I've also read that the G-sync variation is not part of the card but is an external part no on the GPU board.

So now I'm wondering what can I do : is there a way to force the vbios flash or to change the PCI ID ? I really need some help here. I'm no expert and I've try as much as I could. Maybe I need to do some vbios editing but I don't really know how to do it and what to do exactly to make this work.

Thank you very much for your help guys

 

It's possible. Just try out different 1BE1 Vbios ..

eventually, one will work.

Okay so first, I had some evolutions since myf first mesage:
-I've managed to make the card boot on the laptop screen by flashing a MSI vbios that had the same device PCI ID (1BA1).
-I tried to install with edited .inf files the nvidia drivers but I still have the error 43 once right after the driver installation
-When I try to flash my former vbios or any 1BE1 Vbios on the card i got this :
"

That's why I plan to Hardware flash the vbios of the card in order to change the PCI ID. I will copy the vbios of my old card in the new one with this tool CH341A (I will save both of them first of course, in case something goes wrong I'll reverse the process)

Do you think this might work ?

The other option would be to change de firmware on my laptop to make it recognize the 1BA1 PCI ID as a compatible one, but Idk if that is the best option

 

Hardware vbios flash is the only option i would reccommend, even though I don't know how to do it myself.

 

Could you post your original vbios and the ones you have tried here?

 

Following this - I was able to get my 1BA1 card to read a 1BE1 VBIOS but was unable to get past driver errors (error 43.)

 

I'll take a look at my gtx 1070 vbios when I get off. If it's a 1BE1 , I'll dump it for you.

 

What machine is it from? Would love to take a look regardless.

 

GT73VR

 

What file size is your VBIOS?

 

Here is the link to my vbios.

Here you go

Access to the folder with 2 Vbios for 1BE1 for Vortex MXM's to work in Laptops.

It can be flashed using NVFlash included in zip's

Have fun.

 

Hi! Thanks for your replis.

So i would just have to NVflash this on my 1BA1 card and it would work on the GT72VR 6RE that is requiering a 1BE1 PCI ID?

I try this right now.

 

Hi, so the bios I had on my 1BE1 GPU that died was this one

The Original bios on the 1BE1 card was : https://www.techpowerup.com/vgabios/210661/210661

The bios that made me have 1BA1 card using the integrated monitor is this one : https://www.techpowerup.com/vgabios/197312/197312

FYI guys, I will receive the adaptator for the programmer tomorrow, i'll tell you if I manage to change the PCI ID this way. If it does, I'll make a tutorial post about it that's for sure.

Btw, there is a risk that I just fcked up big time by using the CH341A, which is a 3,6V adaptater for the chip which is a 1,8V....the card seem to be still be working fine with no driver installed, but i dont know what kind of dommage this bad hardware flashing could have done. With the CH341A I've manager to install the .8A bios I had which was reserved for 1BE1 cards normally, but the PCI ID didnt. But this happened with the wrong voltage so I will be sure tomorrow once I'll have try with flashrom on linux and a proper 1.8v adaptator for the programmer.

DONT TRY THE HW FLASHING ON YOUR OWN unless you really know what you are doing. I'm now in contact with flashrom dev team so they tell me clear me what to do. I'll keep you posted and will probably make a tutorial on what I've learn so far.

 

I think your getting mixed up let clean that issue up for you

If your MXM Card use the vbios i gave you

1BA1: https://mega.nz/#F!jE8ThSCQ!R25t0AIJLRaXExItYRrBrg
1BE1: https://mega.nz/#F!KN8Xxa7T!lF_UmhBoPn-oa_rH2Ges-Q

What i mean by this is If the MXM currently in your system is 1BA1 then flash the 1BA1 Vbios if its a 1BE1 then flash the 1BE1 vbios.

The ones i've supplied will enabled the internal screen to work, As far as i am aware no GT72VR has an ID lock it will have DSDT entries for both versions of the card the only difference will be possibly G-Sync.

Cross flashing between the two Device ID's will not work as all your going to get is Code 43 or a blank screen, I should know i have been trying to change my GTX 1060 device ID for ages, there are transistors on the card that will configure the GPU to a set ID and the Vbios checks this hence the Code 43 issues.

So if your after just making your internal screen to work just flash the correct Device ID Vbios i have linked.

As for your little 3.6v on a 1.8v chip you could be lucky and not killed the vbios chip or you just placed it in a pan of boiling fat, its why i use a Sky Pro -> 1.8v adaptor with SOIC8 test clip.

If you can still dump the vbios on the card with nvflash you might have lucked out.

 

This is definitely derailing the thread but I've been trying to crossflash the 1070 Max Q in this Razer Blade 15 with matching device IDs (10DE-1BA1) and I get error 43 driver error every time - is there something I'm missing here? Subsystem ID and Board ID don't match, is that a factor?

 

@amihail91 It depends how Razor does it Vbios, maybe someone in the Razor threads will be able to help you.

 

I suggest you try the Alienware gtx 1070 max q vbios.

 

First, thanks for sharing. I installed the 1BA1 Vbios, and yes my laptop screen is working with this one too (the one i had found was probably older but was working too)

However, when I do a custom install of Nvidia drivers, modifying the nvmii.inf file and without Windows checking the drivers, I can go through the install but right after, I still have the code 43 again :/

Why do you think I still have this problem? could it be the mess I did with the 3,6V programmer ? If i do a clean Hw flash with the proper 1.8v programmer Maybe I could fixe that?

 

Strange that even flashing the right vbios your getting code 43, did you run a DDU session in safe mode? Do you have a backup of the original VBIOS?

I have a back up and yes I used DDU first before installing. Still got error 43. :/
I added this line in the nvmii file:
%NVIDIA_DEV.1BA1% = Section142, PCI\VEN_10DE&DEV_1BA1
If you have a card working that way, could you send me the .bin file you can extract with a hardware flash?
Maybe there are some part of the vbios that cannot be changed only with nvflash and requiere an hw flash to make the card fully compatible.
What do you think?

 

The vbios be it dumped by nvflash or SPI programmer will be the same.

However have you tried both vbioses for 1ba1 I uploaded will look later when I get back from hospital I might have other 1ba1 vbioses.

You sent only one 1BA1 vbios, this one : 86.04.42.00.03

I got it installed with nvflash with no problem, but after Nvidia install : code 43

When do you plan to come back ? I hope you are fine dude!

No more image on the laptop screen, I flash back to the previous one with remote controle

 

?? Have you ones I have linked

Sent from my SNE-LX1 using Tapatalk

 

I didn't see you had send a list, now I'm trying them all.
I keep you posted!
Do I even try "max-q" vbios ? my card isnt max-q :/

 

If I wrongly change the .inf file in Display.Driver, can it leads to an installation that goes to the end, but with an error 43 at the end?
I added this line : %NVIDIA_DEV.1BA1% = Section142, PCI\VEN_10DE&DEV_1BA1
In device manager, when I check the "events" on the GPU, all status of the installation are at 0

 

Change the section to another with in the same driver. So try a lower section ID

At hospital will mod driver for you when I get home and link you to the file.

Okay I have to work too, we talk latter. I'm telling dude if you make my GPU work I'll give you a tip for that!
Good luck at hospital!

 

Right will need a screen shot from GPU-z so can correctly mod the driver for you.

Ok so you know I tried various Vbios, none of them seemed to work. The one you'll see is not necessarly the best one.
See pictures below

 

Well standard drivers should work fine as that device ID is in the standard drivers?

Sent from my SNE-LX1 using Tapatalk

 

No sadly I dont think the 10DE 1BA1 1462 11AF is by default in the drivers

 

however there is an 10DE 1BA1 1462 11AE, so which driver you using Standard or DCH?

Also i take its for the latest driver as well??



Edit: I have modded the .inf file for the Nvidia DCH 461.30 drivers, simply Download the attached file and extract it into the Display.Driver folder.

It should work on both Standard and DCH 461.30 drivers.

 

I usually go for standard, and yes last drivers is the best I guess.

 

@Axel-d-S i edited the pst above you with the modded .inf file

 

Thanks! i try this right now!

 

I have to put windows in no driver checking mode?

 

WHOW big news, I had an error message saying I need DHC package ! Never had this one before.
Can i try again with the same Nvmii file in a DHC package?

 

You can use the DCH version just to test it yes. Driver signature enforcement needs to be disabled.

If it works and you want to use the standard version of the driver look for 10DE 1BA1 1462 11AE then copy that line and change 11AE to 11AF

Do the same to each section and you should be golden just remember if your going from standard to DCH or the other way make sure you run a DDU.

Well... when I try DHC it says I need standard and when I try standard it says i need DHC

 

Run DDU in safe mode.

Will try and download the standard driver and mod it for you.

Oh yes right i totaly forgot

 

Just downloading the standard driver now for that one inf file now. will take me 40 minutes as my internet is crappy slow.

 

I feel you dude my internet is **** too ... now trying a reinstall with your first nvmii file after a clean ddu

 

goodluck

 

I had a fail installing graphic drivers :/
