Boyise's RX480 (REF) BIOS V2 - DUAL Mining
v2 for you all
STATS:
31.25MH - ETH
334MH - SC
DCRI 22
31.25 = 1180/920 2250/1000 (I used 2250/920)
TEMP: 75c @ 100% fan in a hot room
EDIT:(Cool room this morning and 75c with 50% fan)
Power: 180w @ wall using EVGA 850 P2 230v @ card = 169w (using mem @ 920mv)
Optional: power on mem can be dropped, some go as low as 900 maybe more...most I find wont go past 920 but find your optimal with out crashing, default as always is 1000
win and Linux ver attached, numbers quoted from windows...Linux may find you get less...
I have provided 3 versions
1) Windows 31.25
2) Linux 31.25 (number maybe less)
3) Windows 31.5 (seems unstable on some cards so use with caution) Lower power than v1
This rom would prob work on a 1050w output PSU with 6* 480s but try at your own risk.
Have fun
Boysie
PS: Windows 31.25 rom has options to up the mem speed so if not sure you can handle 2275 speed test it before flashing 31.5 which is set to default to 2275.

Will test it when iam home from work.
Thanks for your sharing
PS: a super low power rom would be nice xD
You got any ideas how to allow the OS to detect the card after bios flashing?
Disabling sig check is not working for me. It's windows 10.
Might just give up on dual mining and focus just on 31Mh of Eth alone instead.
What works for me is using DDU to uninstall drivers in safe mode, reboot in regular mode and install 16.8.2, reboot directly to safe mode, swap the atikmdag.sys for the patched one, reboot using 'disable sig check'.
I've also had success in swapping the atikmdag immediately after 16.8.2 install (without restarting), and then directly booting with disable signature check.
The patched atikmdag is what bypasses the "BIOS signature" detection.
Then we disable "driver signature" checking to allow Windows to actually load the patched atikmdag.
The files for various OS/driver versions are here

More details are available in Heliox's thread.
To be honest the Auto one will work for any but its likely to use more power...if you are struggling the Linux one will be fine on Windows...just not the other way round.
@hasher @ShawnY the patched file is 16.7.3 but I use 16.8.2 with out any issues along with the patched file.
@Lokken86 @Logicaluser no need to disable sig checking, just sig the patched file yourself using the tool and it will work with out option 7 on boot. if you want to use it on many systems just export the NGO cert in root cert auth and import it to the root cert auth store on all the rigs and use the same sig patched file and it will just work in test mode...a few threads about this already so steps are available.
@Lokken86 the patched file ignores the BIOS checking for a sig BIOS..meaning you can use custom BIOS. you just need the file ...its here: http://www.win-raid.com/t892f16-AMD-and-Nvidia-GOP-update-No-requests-DIY-19.html#msg30028

no idea in Linux.
It sets ALL DMP states to 920mv...that's really not a good idea.
remember if it thinks its a new card it will reload the driver from the driver store and overwrite your mod file.
Dual mining
The Linux rom seems fine but it chrashes after a few mins and sia get 0Mh/s on all cards.
But the consumption seems nice
Boysie
After a few secs the monitor flickers and fragmentate the screen and than it hangs.
On Ubuntu 14.04 it didnt even run...
I have finally got all 6 cards running on 31.25 Boysie Rom
Only adjustment made is 950mv on Mem for all 6cards. Single mining Eth only.
910W @ Wall
Lucky for me, I forced my mainboard bios to boot from my onboard intel GPU, and once in windows, it detected the card, but called it a standard VGA device.
Atiflash amazingly was able to detect the card and I could flash the old ROM back onto the card. Everything works normally now.
I wont be playing with any more custom ROMs until someone makes one specific for the PowerColor cards.
@boysie why don't you grab the new official ROM that was released by PowerColor and take a look at it? You can download it at the link below.
