I received my Sapphire RX 480 Nitro+ (4GB) GPUs yesterday. Is there also a ROM that I can use?
Without any modification I get ~22MH/s while mining ETH.

You can easily mod it yourself a little bit +2to4mhz. Save your bios rom with Atiflash and open it with PolarisBiosEditor. In the TIMING section copy 1500mhz strap(long code) and replace 1650, 1725, 2000mhz straps. Save and write new bios.

Ok, I will try that later, thank you. Is there a thread/website listing good settings for GPUs so that I do not have to test all settings?

ohh i forget... you need to modify your drivers aswell ^^

Boot windows
Install driver
go to device manager, right click on your gpu, disable it.
reboot to safe mode
replace atikmdag.sys
open the signing tool "http://www.ngohq.com/?page=dseo" and sign that file. C\Windows\System32\Drivers\atikmdag.sys
open admin cmd window and type "bcded /set TESTSIGNING on" if this command is not working try this: bcdedit.exe -set loadoptions TESTSIGNING
reboot
Device manager, enable GPU again.
Write new bios
reboot
Done.

In my case nitro+ 8g core 1125 and mem 2000 works perfectly

WAITING for bios for extra mem timing strings (2100 and 2300mhz) that is too much for my brain to make extra strings.. Eliovp maybe little help with those extra strings!? ^^

open the signing tool "http://www.ngohq.com/?page=dseo" and sign that file. C\Windows\System32\Drivers\atikmdag.sys
open admin cmd window and type "bcded /set TESTSIGNING on" if this command is not working try this: bcdedit.exe -set loadoptions TESTSIGNING
reboot
Device manager, enable GPU again.
Write new bios
reboot
Done.

if i do this part i won`t have to manually disable driver signature every time i restart ?

no
