Hi,

I have very strange problem with RTX 2080 Super. When Pc starts there is black screen and monitor is not recognized (GPU too).
On the other hand when I starts from integrated graphics card and I install NVIDIA drivers monitor starts to be recognized and I can use card (play games, mining).
I have tried to minie ETH for test only (im not a miner) and with setting 50 power, -200GPU and + 750/800 MEM it mine with speed about 45MH/s so I think that it is good reslut.

I cant test this GPU using MATS because in DOS mode it is not recognized.

Moreover I have tried to build a "RIG" with RTX 2080 and GTX 1070 but when 1070 is connected and installed, 2080 display code 43.
I associate 43 code with memory but I would like to be sure that the problem is in memory.

Ofc I have tried to upload same bios from Internet and It didn't help. I do it using nvflash.

Where it could be a problem? Have you ever meet similar work?
