Заголовок сообщения:  MSI GE62 7RD Apache (MS-16J91) Error in graphics memory with chips and without chips
Hello again, I'm going crazy with this laptop, it's an MSI GE62 7RD apache (MS-16J91) with i7 gen 7 processor and GTX 1050 graphics card (not Ti).
They gave me this laptop with a short circuit in the 19v input mosfet, I replaced the mosfet and the laptop works perfectly, but the dedicated graphics card gives error 43 in windows and when I do the diagnosis with Mats (400,250) it tells me that errors in the vram modules A1 and B1.

After this I replaced the A1 and B1 modules, I did the diagnosis again with mats and it gives me the same error again, but if I do the diagnosis again for the second time it only gives me an error in the A1 module, if I turn off the computer and I carry out the diagnosis again, the error returns in A1 and B1, I carry out a second diagnosis and it only marks an error in A1.

Finally, I unsoldered the A0 and A1 modules and after carrying out the diagnosis, it continues to show an error in A1 and B1 and in the second diagnosis, an error only in A1 (all this without having soldered the chips)



First test without A0 and A1 chips

Hello!
Take a photo of your chip and memory.
and on the photo mark your numbering of defective memory chips.

if everything was done correctly, it is possible that the GPU was dumped.
Or the memory controller in the GPU has failed.
You can still get confused, the memory and GPU are removed. then call from memory to GPU.

Sorry for my english, it's not at all =)))

Had the same problem with 1050 and mats, also gpu works fine. Try another mats, 367 for example. Also check voltage and vram resistance

The voltages are correct in all the chips and I have also tried version 367 but it gives the same errors, I forgot to mention that the 4 chips are new

Прошейте новый bios на программаторе, проблема в прошивке может быть.

Flashea una nueva bios en el programador, el problema puede estar en el firmware.



I try it, thanks
