I'm currently building my 6th rig and since the shortage of RX 580 cards in the market i decided to build a low-range RX 560 rig with 9 cards for a change.
So it's build and operational, but then it was time to update the bioses with mining timings and that's where it goes south.
I copied each rom with atiflash, used polaris bios editor and applied the one step memory fix, updated the bios, reboot and then windows reports the RX 560 card is not working properly... And not only one card, but all cards i updated.
So because of the GPU shortages, i have 3 different RX 560 cards. 2x Sapphire Pulse, 3x Gigabyte OC and 4x MSI Aero ITX OC, all 4 GB ofcourse. They all have different bioses and i modded each card individually. All cards have the same problem. If i reflash their original ROM, they start working again, but not with a decent hashrate.
The OS is a clone from one of my other RX 580 rigs.
I tried Polaris 1.6.4 and the latest 1.6.7.
I tried AMD drivers 17.11 (Crimson), which i found out are working the best on my other rigs, and the latest 18.2.3, but both have the same problem.
Anybody got any clue why windows reports the GPUs not working correctly after i flash a modded bios? I'm quite lost with this one. Please help.
ps. don't buy the Gigabyte cards. I found out they only have 14 compute units, while the Sapphire and MSI both got 16.
