Good morning to everybody

I have modified the original bios of my Gigabyte 5700XT, only copying the value of the VRAM that appeared in the 1550 field in the rest of the fields. I have flashed that BIOS and now I get 56/57 MHS with a consumption of 123W.

I am a newbie to AMD and I ask for help, how can I modify the BIOS to obtain less electricity consumption? Is there a way to reach 61Mhs as I have seen in some Internet video?

I have no AMD experience, I have never modified BIOS, can I download a Bios Mod for my card from somewhere?

Thank you very much and sorry for the inconvenience.
