XFX RX 5600 XT Thick 2 pro BIOS update problem(cannot find model id)

[Endless Paradox]

Hello,everyone.I have an 

XFX RX 5600 XT Thick 2 pro.

I saw that a modded bios by the company that boosts the memory clock by 250mhz.

I have been doing some research and this is my graphics card:

My issue is that when typing this model name or SN on google there are no results.

The updates on the official websites show this only

The issue is probably that mine is a chinese model while they only consider usa gpu in the website.

How am I supposed to update the bios on mine? how do I find the appropriate file?

 

Additional info:
When I install the drivers it never detects it as XFX it detects it as 

but hwinfo 64 detects correctly

Also the sticker clearly said 14gbps but here on the amd interface it show 12

I am not sure if this is normal but I hope this information can help.
