shift-reboot and choose smth like "don't check drivers signatures" at startup menu
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.
open admin cmd window and type "bcded /set TESTSIGNING on"
reboot
Device manager, enable GPU again.
Done.
Thank you, guys, both ways work.
In my case I even did not need to disable/enable gpu, I just signed that mod driver and it works well after reboot.
It works well on win10 and on win7.

Huh?
For Windows 10 users, you can do this:

i) Press Windows Key + X to open Power User Menu. Select Command Prompt (Admin) from the menu.
ii) Once the Command Prompt open, enter bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS and press Enter. Then enter bcdedit.exe -set TESTSIGNING ON and press Enter.
iii) Close Command Prompt and restart your PC.

If this fails for some reason, you can reboot with Signature checks disabled by rebooting into advanced options (Hold left shift key while hitting reboot button) and hit F7.

You need to copy the modified atikmdag.sys file into your drivers folder as well (C:/Windows/System32/Drivers)

File can be found here: Here

I have just bought one reference RX480, flashed mod bios, with stock driver I get Error 43 in device manager.
If I replace atikmdag.sys with the modified one, I get Error 31 in device manager.
"bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS" and "bcdedit.exe -set TESTSIGNING" are done, both windows installations are in testing mode.
Tried both Win7 and Win10, original drivers 16.7.3 and 16.8.2, result is the same.

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.
open admin cmd window and type "bcded /set TESTSIGNING on"
reboot
Device manager, enable GPU again.
Done.

Does it apply to Windows 10 as well?

Should we enter the test mode?

I only have Windows 8.1. So I might have to wait for the 8.1 drivers.

Applies to 10 as well.

1x XFX BE ref - 95W (GPU-Z) - 30MH/s
3x PowerColor - 90W (GPU-Z) - 30MH/s

Total Power draw 735W on the wall

using Tighter strap
First I set to reach the target speed (30MH/s)
then lowering power limits down to the stable points.
Each GPU have different bios parameters.

Win 7 - Crimson 16.7.3 (Configured using RDP - no monitor attached)

Did you change the timing strap in the bios or using other tools? The efficiency sees not no high as it is 735W for 120 MH/s.

yes i change the timing strap. about 150W each card

Is that dual mining? If that is solo mining, then 150W is quite high.

Did you change the memory strap yourself?

if the total power is 735w and you have only 4 gpu then each one is not consuming 90w only...more like 150w minimum

yes gpu-z always show less than real power draw.

@zcrewsmok: Could you show me what is code 43? Maybe I need the screenshot. I followed by this reply and it's working now. Let do by him steps.
https://bitcointalksearch.org/topic/m.15958294
I forgot to turn off digitally signed drivers. Now it works.

But how to run a 480 with 380? After substitution atikmdag.sis file does not load windows.

are you going to publish mod bioses for non-reference RX 480 (like MSI Gaming X)?
In technopowerup review they show it has micron memory. Will oc only with increased vddr votage. And will not oc to 2200 ((

So at this point we don't know or don't think that the non-reference cards will perform as well?

ok finally got the rom to work, had to do a full re-install of the drivers , copy the modded driver and then boot with option 7

not sure how to get option 7 to auto load on boot.

One issue I'm seeing

dual mining seems quite neutered compared to stock ? at 30 dcri I am seeing 24.5 eth and 360ish sc when before I was getting 23.5 eth and 420 sc

now if I mine eth only I was seeing high hash rates around 31mhs

Also the cards all now detect and 4GB I know others mentioned that as well, it does seem  that the core clocks are maxing around 980 which might be the reason for the low SIA or dual mining ?

Try this one Marvell, 29Mh otb, low power usage


Greetings
thanks Marvell1 and Eliovp!
I have HIS rx 480 custom 8gb. Can I to use this room for it?
thanks very much.
No need to thank me Eliovp did all the work

btw I figured out the why I was getting such a low hash rate dual mining, this ROM is so efficient you have to set a powerlimit of +10 or +20 in claymore or via wattman to force the cards to pull more juice
I was using around 3.5 (17 amps at meter then when mining 19amps sometimes 20 is how I got this number)  amps for six cards to mine. 

With the powerlimit set +20 and I see a solid 4 amps maybe sliggtly more for six cards which is still fine since I'm getting the following results :
https://forum.ethereum.org/discussion/9090/rx480-reference-custom-rom-31-mh/p11

175 or so eth and 2k SC  , solo eth was 181 eth and 3.5 amps so its a bit better to lose 6 or so eth to gain 2000 SC or DCR.

What I did find is these cards will take as much juice as you can give them so be careful I saw rates as high as 490 SC and 28 Eth

if someone bricks his rx480 due to wrong bios flash (not recognized, system doesn't start etc) a famous ati/amd 1+8 bios recovery works perfectly. Google for it.
