Make sure that your sli cable is working fine

But the problem with blue, white or Blackscreen stays also with Slave GPU in Master MXM slot. Only one GPU and it doesn’t matter which VBios.

 

I really can't understand your problem ..

The master bios should be used only with the vga in the mxm 1 and the slave bios should be used with the vga in the mxm 2..

The bios is extracted from my system and you can see it in the pic and you said that you successfully flashed it and card was working

So how it died after that ? And why you were flashing it again ...

I flashed both with your 2 VBIOS. Master with 05, and Slave with 0D. From this moment the system freezes. Then I removed both cards and tested both cards in master MXM slot. I flashed the Slave card with a VBIos for the master Card. And it also did blue, white ... Screen. The master card which I didn‘t flashed with 0D VBios works great, the Slave not.

 

What's your bios version ? Use any bios after A11

Also about the vbios that I mentioned .. have you downloaded it from the link i posted above ?

I'm using the 05 bios now and flashed it to the card that was having the 0D version and it works perfect in the mxm 1 slot ..
Also try to ddu the driver and make sure that you use the bios from the link in my comment as it's made for dell and I'm sure it's working as I just flashed it to my card again and works perfect

Also you are saying that both are doing blue white screen then again you said that the card works perfect..

It seems that you have faulty gpu

No, I only said the it could be that the slave card now is faulty. Master works fine. But before I flashed your VBios from the links both cards worked fine. So I think during the flash something goes wrong. It also could be that the Slave card was a little bit faulty and now it comes to the light.
I will later test it in an MSI GT70

And my systemBios is A12 unlocked.
Or do I have to install Win10 in UEFI?

 

You should use uefi system with windows 10 also to get it working properly and try to flash it again with the slave bios and add 6 to skip the id mismatch

Ok, I try it in Uefi. And with -6 I flash it always.

 

No luck with uefi and another flash.
But Strange thing. I flashed an MSI VBios and installed the Slave card in GT70. The card is working fine in there.
