This is very important, even more when profitability is very low. Here are the steps we did:

Tools needed :

GPU-Z – https://bit.ly/32LonaI

flasher – https://bit.ly/2TlZlMl

BIOS editor – https://bit.ly/2IcYNSC

GPU BIOS collection – https://bit.ly/3crXCfV

So for test purpose we have had 2x RX5700 non XT version. We have edited timings and also upgraded nonXT version to XT.

Follow the steps:

• Download you gpu bios to backup with gpu-z

• Extract flasher to your C: drive

• Download Original XT version from GPU BIOS collection

• Open XToriginal.rom with BIOS editor and edit timing straps and save bios in your flasher folder. Straps edited copy 1500mhz to lower 1850…..etc (similar way as RX570 4gb cards) . These cards does have 2 bios, so edit both of them, after each time editing you need to save. This tool doesnt allow you to edit 2 bios at the same time.

• Now you need to upload these to your graphic card. Open command prompt as administrator . Navigate you you flasher folder  (cd => cd flash => amdvbflash -i ) this will give you information of the gpu connected in your system.

• Next you need to unlock gpu ROM to upload new BIOS type in cmd( amdvbflash -unlockrom 0 ) 1,2,3 if you have more then one gpu

• Last upload new BIOS to you GPU type in cmd ( amdvbflash -p -f 0 newBIOS.rom ) newBIOS is your saved .rom file name

After flashing, the computer must be restarted. We can already admire the new data in GPU-Z. In this case I had set the boost clock a bit higher. Now the value is no longer 1925 MHz, but 2104 MHz. In real terms the card reaches 2050 MHz with the right cooling.

Easy as that, reboot your system and your hash-rate should increase. If you have done everything explained here. Other flasher versions wont work , download links provided on top of the post.
