Topic: [UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing - page 45. (Read 231013 times)

Hi! Im using RX480 NOT-refference cards, Sapphire NITRO+ Radeon RX 480 (11260-01-20G)(GPU: 1342Mhz, MEM: 8GB 8000Mhz 256 bit) and  Radeon RX 480 HIS IceQ X2 Roaring OC (HS-480R8DCBR) [256bit, GDDR5, 8Gb 8000MHz], can i flashed RX480Mod from heliox ?

better to make 2 rig, currently im running 2x R9 390 in custom rig, and 1 other running 2x Rx 480 (flashed)

Ok. Let's call it success

I've flashed two my cards and run a heterogeneous rig with 3x R9 390 and 2x RX 480 (flashed)

I called it "success" because after flashing each card individually with fresh driver and signed atikmdag.sys gave me 29.2 MHs

After adding all 5 cards in rig they can do exactly as they did before - 24.5 MHs

All is with CDM and single mining ETC

I'm sure if you will have only RX 480 - they will work fine, but in combination with other cards (in my case R9 390) I've got zero gain

use this software for signing atikmdag.sys "http://www.ngohq.com/?page=dseo”.
the bcdedit.exe -set  loadoptions TESTSIGNING used just for test the sign, not for signing software.

Am I right that to fix situation  I should do next:

1) Flashing card. Restart normally
2) Uninstall driver. Restart normally
3) Restart to safe mode. Replace atikmdag.sys. Sign it with bcdedit.exe -set loadoptions TESTSIGNING. Restart normally

Should I disable and enable card in Device Manager? If yes - on which of steps?

wrong step
-flashing rom
-remove driver using dd driver uninstaller (safe mode)
-restart as normal instal the new driver
-restart to safe mode, replace the atikmdag.sys then sign in it..

don't instal driver again after it.

Anyone know of bios mods (specifically power savers) for 390x?  I tried searching a bit online, but that was a lot like wading through shit. With ads.

Ok. Attempt on flashing 1 rx 480 with 480lowenergyOK.rom is failed - so I need your help

I did everything according to citronick guide:

Win 7, originally I had 5 cards (3x r9 390 and 2x rx 480) and 16.8.2 drivers

1) I took out all cards except 1x rx 480
2) I run cmd in Admin mode and used 480lowenergyOK.rom ROM to flash
3) Rebooted. At this point my card was not recognized by AMD drivers, tried to install drivers and automatically did it. After restart I've got the standard low resolution window, so actually card was not supported by driver.
4) I've disabled this card in Control Panel, Device Manager.
5) I've restarted to Safe mode in Win 7 you should restart and press F8 after BIOS POST and select Safe mode.
6) I've replaced driver in system32/drivers with modified
7) Launched signing software and pressed switched to signing mode
Launched cmd as Admin and typed in windows/system32 this line: bcdedit.exe -set loadoptions TESTSIGNING. Got confirmation that signing was completed
9) Restarted in normal mode installed 16.8.2 drivers. Restarted and enabled card in control panel

I've got sign that there is a problem with device. I've restarted and despite 16.8.2 drivers were installed correctly my card is still in VGA mode and cannot use the driver

So questions:

1) What was wrong?
2) How to fix it?
3) If I cannot fix it - can I restore my original BIOS (I did not make a backup, because did not know how to do it)? I have second identical card so I probably can copy this BIOS.

SO question:

If I run the 480LowEnergy ROM for my 480s, and hook up my spare 290x to the same mobo, will both of those cards be able to hash together on the same miner?

If I understand it correctly, the 16.7.3 drivers are still AMD so they will work, and all the ROM and does is change how the 480 operates. Correct?

Thanks,

Which ROM did you use? Link please

I use Win7 and atiflash 2.74 (dual boot with Ubuntu).

Did you use Linux to flash the ROMs? If so, what version of atiflash worked for you? Or a different software to flash the ROMs? Really trying to avoid building a Win10 system for flashing

What atiflash did you all use to flash the ROM on Linux? OS is Ubuntu 16.04. Mining works, but atiflash doesn't recognize my cards to do the flashing. Thx.

Only for Windows
Patched atikmdag.sys files can be found here: http://www.mediafire.com/download/x2h57df0ajae4dk/AMD_Patched.rar (for sign use dseo13b utility).

If you do this BIOS edit manually do you have to still go through the whole moving atkdmad.sys file and signing it with the utility and all those steps??

@citronic the flashing is succes with your link but i get this trouble
any wrong with my step ?
1. flashing rom
2. restart to safe mode remove driver with DD driver uninstaler
3. restart to normal instal new driver
4. restart to safemode replace atikmdag.sys
5. restart to normal mode

after it the driver not detected my card
this is my screenshoot : https://s9.postimg.io/hgt2yr0tb/Untsseitled.jpg
update now succes

Not sure where i found it.
If you have not found it in the links posted above i posted it here:
