HDMI Port on RX 470 breaks driver? (What)

[OleksiiTech]

So, mining RX 470 reflashed to 570 (since only fitting firmware was for 570) works fine, great even, when connected to Intel's iGPU. Driver can be installed without problems and patchers, runs benchmarks and games, large language models, all without problems. But when I connect it to hdmi which I "activated" by soldering, it breaks, shows 0 mhz and... look at screenshots. In Ryzen 5 5600 system though automatic drivers fix resolution, but problem remains same. Normal GPUz screen is through iGPU. Bad one through HDMI port on RX 470. Any reason why this happen? In device manager I get error 43, ati patcher doesn't help. Adding all pictures that may help. GPU Memory is samsung k4g80325fc-hc25. Thank you.

Without knowing which bios is currently flashed, did you flash this bios before?

Sapphire RX 570 VBIOS

Could be caused by the GPU since it is a mining chip or the solder job.

This bios might also be interesting if the card is working properly

The first you provided is the one flashed now. I will try to flash 580 2048sp.

Patched 580 - same thing.

Through Intel's iGPU it works. So.. Bad soldering?

To get a miners video output to work you must verify traces are not cut and that resistors/caps are correct.
