I used this for a video card Yeston RX 460 4 GB.
https://www.techpowerup.com/vgabios/196766/196766Unlocked up to 1024 shaders. A bit upset with the video card. On the ETH only 9.4
I used timings from 1500 for high frequencies. Strange, but the result for ETH does not change in any way. Generally does not respond to an increase in the frequency of memory. On 1050ti it's different. Increasing the memory frequency increases the H/s
I think now to patch it with a bios from RX560 another manufacturer. Tell me, if I get a brick - can it be revived on a computer with a built-in video card?
