Update bios for my sapphire Rx 480 nitro OC and got lower hash rate

[pornluver]

instead.

I go here

https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt

I flash the rom using atiwinflash

The result is my computer won't boot

So I use original ram for my GPU and then change the value to match the ROM I downloaded from the link.

Polaris editor reports that everything is exactly the same. There is one number on top left that's green. I don't know what number is that.



Things load but speed drops to 20 Mh/s instead of up to 29 Mh/s

I used the recommended clock of 1125/2080

Which is much lower than my usual settings. I know.

If I raised the clock rate, the computer freeze.

Actually what kind of bios I should use for my system anyway? Is there any bios I can just flash as is? If so, how do I know it's the correct one?

I uses Sapphire nitro oc RX 480. The memory is samsung. The memory is supposedly 4GB but all Sapphire nitro RX 480 4GB with samsung memory contains 8GB memory actually.

There is another main difference between the 2 bios

My original bios have this number when opened in atiwinflash



113-2E3471U.O6A

While bios I downloaded have this number

113-2E3470U.S5U

I have no idea what that number is and it doesn't seem like it's something polaris editor can change.

This is my GPU-z screenshot

I think the best way is just change the your original bios gpu memory strap from 1750 to 2000 using polaris editor. i use atiwinflash for backup and flash back the bios.
I got from 24mhs to 28mhs. later just use strixx, wattool or wattman to change the memory clock and vcore to your gpu.

Won't reach 30 mhs. Without bios editing I can achieve 27mh/s. Are you sure that's the way

Yep its that easy. use 1750 if its samsung memory or 1500 if its hynix/elpida (some people may use 1625 for these last two?)
