Question Rx470 8gb outputs display byt Gpuz says it clocks at 0 mhz

[jackob006]

Hello so i have this problem i bought a graphics card the rx470 8gb only dvi version and the task manager cant seem to recognize the card (in windows device manager says error code n.43)
It outputs display since its plugged into it and the fans spin but its very low performance, maybe even worse than the igpu.
I have tried flashing the vbios it just says sybsystem id mismatch
I have tried downloading various drivers but they just say an error occured (none are installed or not functioning properly while you literlly can see ots version in techpowerup gpuz)
Also tried disabling igpu and i still can not get the card to perform as it is supposed to. Any help would be apprieciated as to why this problem occurs and how can i solve this. thank you!

did you try this vbios?

ddu uninstaller, reinstall amd drivers then try using pixel patcher

Typical after-mining card with custom BIOS optimized for mining. I had quite a few of those pass through my bench after the Ethereum gig got closed... They get sold for cheap as-is, I bought 12 RX570 8GB on FB marketplace for under 300$ recently and all had custom mining firmware and dust but no other issues. Mining is safer for them than gaming if you ask me - less thermal cycles and load changes which make electronics age.
To find out which BIOS you need, you would want to read the marking of the memory chips. Polaris GPUs all use DDR5, but different memory chips require different voltages and timings stored in the BIOS.
The popular ones are Samsung K4G80325FB or K4G80325FC, Micron MT51J256M32HF, and Hynix H5GQ8H24MJR, and these 4 are not interchangeable and can all be found on the same make/model of the card... need to know exactly which are mounted on yours.
Changing thermal paste and pads when you take the heatsink off is a good idea too. Also, it would be helpful if you would mention the card manufacturer and post good photos of the PCB front and back so that I can try and point you to the right file. In addition to memory settings (which probably are your issue now), BIOS has all other card features such as TDP and current limits which correspond to thermal design and VRM which varies. I would worry about flashing after there will be a proper file to flash.

Another thing to mention is your motherboard BIOS setting - some AMD cards do not work properly with automatic memory addressing allocation, for there is a BIOS setting called "Above 4GB MMIO" or similar. Try toggling that too.
