Thank You bro you saved the day

Yess, this hash rate is pretty normal.
You can try to increase the memory frequency to improve your results and also underovlt a little bit to reduce power usage.
Since you are pretty familiar with bios flash right now, you can also try to modify the bios yourself with polarisbioseditor and lower the timings. It's pretty simple and you will find guides or even videos on youtube.
With everything properly configured you should be able to archive at least 29Mhash with that card
