Vega 64 OC, flashing, bios problem

Hello, noob to hive and its, also haven’t put together a rig in 2 years so a lil rusty on lingo, new to hive. So prolly ask some noob questions.
I was looking to the kick the mh up from 34.

I wanted to flash bios to a 56 per guide on hive, but my bios version does not have a corresponding 56 bios number i could find? 016.001.001.000.0008769???
Anyways 34 is a long way from the 50isih i think it should get.

What does the highlighted red box and number stand for something for the fans ?
there a Straps guide? where do you put the vdd in the oc menu?

thanks for the help.
