Testing PBE 3.0 , seems to have a issue after clicking on Timing Patch with RX550 card or this is normal?
Screenshot for RX550 Gigabyte Hynix:
Same for RX550 Sapphire Pulse but with a bonus message:
Thank you in advance.
Next time pls write to my e-mail. You will get faster answers and this is not meant as thread for my PBE it is for free bios modding. If you are in hurry and got big problem also Telegram.
It is normal for lot of cards it lower voltages. Power saving option is better since it also tweak clocks.
That is not a bonus msg

It is timing pick, not sure if the first one will work with 550, but try it, if you answer no you will get other one that should work.
RX550 aren't very compatible with this PBE for now, I rework it for RX560 and RX550 will be hopefully soon too.
BTW that's not Hynix, but Elpida (right upper corner).
