@Heliox thanks again for all your hard work, it's like adding a free video card on a 6-rig with your bios.
Attached is my modified bios with aggressive undervolting as mentioned earlier. It might not work for everyone, but I tested it on 18 video cards with 100% success rate, so I say it's pretty good odds.
test on dual mining @ETGoHome ? Also, this is based on the 4gb rom still.
@billcryptokid, yes the ROM I tested is the Boysie XFX ROM from your share drive. I only test with the XFX ROM not the sapphire 1. The other ROM I test with is from bitcointalk which is link in this thread. There is a power saving 1 that gets 29MH which is stable for me and there is a Heavy 1 that is supposed to be similar to Boysie at 31-32MH but it would just crash for me after 30-60 secs of mining.
@Calivet Thank you, I am next to acquire these days 2GPUS 8GB Gigabyte RX480 unfortunately in my country Peru , do not reach the XFX or Saphire , only MSI and Gigabyte and are around 320-340USD .
I see the possibility to import them , but leave as expensive , not much difference .
You that you suggest , the Gigabyte would yield the same? It lei, would function with the latest drivers .
I have not used the gigabyte but if they are ref card, it should work. Maybe someone who has a gigabyte could give you better advice. I do have an MSI ref rx 480 and it works fine.
Can someone show me how to lower my core on my rx480s? Maybe a screenshot? I think thats why my 6 gpu rig is running at 1200watts!!
EDIT: which level do I change? EDIT2: Found out...
I've finally got Win7 to work with the LowEnergy ROM from @Heliox but I must be doing something wrong. I tested with a kill-a-watt and the system without any cards is pulling 95-106 watts at idle. With all 6 of my 8GB RX480s (3 XFX, 2 MSI, 1 Gigabyte) running its's pulling 1,045-1,053 watts at the wall! Thats about 150 watts per card. Anyone seeing the same on Windows 7? I'm using a EVGA Supernova 1300 G2 PSU. Thanks!
I found the latest driver 16.8.2 uses about 15-20 watts more for my XFX testing on some ROM compare to 16.7.3 so I reverted back. You must be running on a more power hungry CPU. The intel celeron 1820 combo would only use about 55-65W or so. I was measuring about 186-198 watts via Killawatt so the RX480 was about 131-140+ watts using the Bitcointalk ROM via this link. It's the only ROM that seems stable on my XFX. Hesistant to test on the other RX480 brands until I find out what's causing this.
Guys any advice on force resetting wattman ? I've over done it on my settings and although I can login to windows, as soon as I do anything the rig just hangs with a black screen (because of memory voltage).
Wattman used to just reset if you go a bit to far.. this time its not. Would save me faffing about with a lot of drivers / flashing if anyone has a quick fix to reset it.
Fixed - Re-flashed to stock / clean driver install / re-flashed using my custom rom version. Working O.K again now.

Have you tried booting into Safe Mode? It should only boot up the Windows stuff and not load WattMan.
So new issue for me, got everything working finally lol been solid for this weekend, then last night a rig went down, tried to reboot and i get a black screen after windows loads, so i ran DDU, reflashed all gpus and same issue, was going to reinstall windows later tonight, but anyone have any ideas?
1. Deinstalled drivers via DDU 2. Flashed low energy ROM using Atiwinflash.exe from cmd mode with administrator ownership using command atiwinflash.exe -f -p 0 3. disabled driver signing check on Windows 7 x64 using these commands from command prompt with Administrator privileges: bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING ON
4. Installed latest 16.8.2 drivers
But now windows starts but it says that Windows stopped card because of a problem.

Try the gpus in another rig? maybe at least one of the cards died

How to fix this issue?
Please let me know if you get it working because i'm considering installing win7 on my 480 rig for the modded bioses (need reboots to go right into mining and not have to press the 7 key for win10)

If a card "died" you think it would still be recognized by windows, maybe ill try flash them to stock and see if it works again...thanks
I have tried to get this flashing method to work. I have tried the instructions by both boysia and heliox. I am able to flash the card and copy the driver, and I have used test mode in Windows 7 and tried Windows 10 booting with driver signature disabled. I have tried the latest driver and 16.7.2. The problem I am running into is that the driver fails to start. It is giving a Code 43: driver could not start error. I have tried uninstalling the video card in device manager and letting it reinstall many times. Is there something else I can try? Anything I am missing? I followed the instructions just like they said.

ASROCK H81 BTC Pro /Celeron1820 with 2 sticks of ram and an SSD while mining only uses 40 - 45w
you lot do seem to over do it a little on your est.
Its easy to see with a 6 card rig and dual identical PSU the diff between the 2 is the System...and on mine that's about 40w
I power on my 2nd PSU the last 3 cards and their risers only.
Everything is in rough estimates as it can go up and down but if you're saying the Celeron 1820 combo is only using 40W then that means the Lowpowerrom uses 150-168w for the RX480 since my Killawatt shows 186-198 which doesn't match what everyone is reporting. Intel reports the Celeron 1820 uses about 53W by itself and off course the numbers will varies depending on the efficiency of our PSU.
I also tested via Dual PSU previous and that's where I got my 55-65W range depending on OS load. Perhaps you have Platinum rated PSU so you got better efficiency?
@Boysie - Is there anything different for your ROM vs the one listed as Heavy 31.8MH ROM on bitcointalk? Really like the performance # people are reporting for it but seems like Eliovp tested on Sapphire and another guy got it working on MSI. I'm not having much luck with your ROM that was designed for XFX on my XFX card.
@nhando my only advice when changing mods is to make sure you remove the card from device manager, so the driver is forced to reload the vbios img it actually uses for the settings..else you have a very odd setup with a flashed card being asked by wattman to do some thing the BIOS is not setup for.
my bios is based on @Heliox rom just tweaked the power down a little and the core to the correct setup, heliox is trying to do som ehting odd with his core setup and this totally fucks up wattman so I removed that in mine...the core settings you can change if you find a better settings for your card, as always this is never going to work on all cards, its a setup I've found works well for my 4 xfx cards but you might need to alter it in wattman(you can with mine) to gain what you need from it.
I've been using 16.8.2 with the mod driver in win10 with my version of Heliox mod I drop the mem power to 980 and leave the core as is, you can vary the powerlimit as required some work as low as -18% still
I had some success moving the core to 1200 (made temp drop 10c) but I was remote and silly me tried using claymore to setup the vddc and core and it properly knackers it up and a reboot happened as a result of a bsod...so no option 7 for me...when I'm back in a few days I will continue to tweak
google polaris bios editor. I downloaded from reddit. (make sure its version 1.4) The modified driver file is at the beginning (page 2 of this thread) where heliox mention it. (win raid or something like that ) go to page 20 or so and look for the atikmdag.rar. You would have to download winrar to unzip it. No it will not cause any other issues. It will tell you that the subsystem ID does not match and it will not flash.
Can you or anyone else post link to moded atikmdag.sys driver file ? I cant find it.

Yeah, I followed the exact same steps you outline but mine won't stay stable. Is it possible for you to share your Wattman picture so I can compare? I really like that Dual mining stats you're able to run. That's fantastic numbers and you're the only one that have it working on an XFX.
@Heliox - Perhaps you can edit the first post to show where all the files is? This would help others as I had similar challenges to dig up the different ROMs, drivers, etc. Awesome work on here and Bitcointalk
Hi all. I have sapphire RX 480 ref 8G. I flashed @Heliox ROM, but GPU clock unstable, change interval 300-1000 MHz. Version driver: 16.8.2 OS: Win 10- x64 How to fix???????
google polaris bios editor. I downloaded from reddit. (make sure its version 1.4) The modified driver file is at the beginning (page 2 of this thread) where heliox mention it.

It will tell you that the subsystem ID does not match and it will not flash.
Can you or anyone else post link to moded atikmdag.sys driver file ? I cant find it.
Here is the rough, and I mean rough process I went through to get the BIOS flashed and atikmdag.sys file taken care of. I downloaded the Driver Signature Enforcement Overrider that I found on one of the Graphics forums... I do not know ANYTHING about this software, whether it is good or bad, and I'm not telling anyone to use it because for all I know it could do harm, but it's the only way I could get the atikmdag.sys file to work. Supposedly it signs the atikmdag.sys file so the signature check passes without turning it off. Below is the link to the software. USE AT YOUR OWN RISK. (If someone else has insight into the software, or knows if it is good or bad, let us know!)
I took steps from @Heliox and @boysie and mashed them together to get it to work. Once again, this is what worked for me. Below are the steps I took from start to finish
1. Start off in Windows with Stock BIOS, Stock Settings, no undervolt/overclock. 2. Reboot to safe mode and run DDU to safely remove all video drivers. 3. Reboot into Windows and download the latest drivers from AMD (Someone said the latest version of drivers cause higher wattage usage, I think this might be the case since I'm at 1050 watts for an 8GB RX480 rig, but I will have to do more testing to figure it out) 4. Install drivers and reboot. 5. Once Windows comes back up you should have all your cards seen in Device Manager and all should be good. If you have more than 4 cards you might have to run the 6GPU fix to get the other working. Don't move on to the next step until you've got all working in Device Manager. 6. Download the latest version of Atiflash
NOTE: Sometimes it's a good idea to flash 1 card at a time. If you want to do this, shutdown your rig, unplug all RX 480s except 1 and boot back up, repeating the below process to flash eash GPU.
7. Open a command line, as administrator, and browse to the Atiflash folder. Type atiflash -i to list the GPU or GPUs you have connected. Once the first one will be "0", then 1,2 and so on if you have more than 1 connected. 8. If you are comfortable with the GPUs that are connected, you can now flash the BIOS by typing "atiflash -f -p 0 BIOS.rom" without the quotes, where "0" is the number of the GPU you want to flash and "BIOS.rom" is the name of the ROM you want to flash to the card. It will give you some info on what it is doing and then take a minute or 2 to flash. When it is done, it will prompt you to reboot to make the changes take effect. You can proceed with flashing the other cards before rebooting, or at least that worked for me. 9. Once all your cards have been flashed with the new BIOS and are seen by Windows with no errors, you can move on to step 10 10. Download the Driver Signature Enforement Overrider software (http://www.ngohq.com/?page=dseo) Again, do at your own risk. This is the only way I got it to work in Windows 7 though. 11. Download a copy of the atikmdag.sys file from the link provided in this thread. Save it to your desktop or folder you can remember. 12. Open the Driver Signature Enforement Overrider software and it will ask you what you want to do. Click "Enable Test Mode" and click Next. It will prompt you to reboot, so go ahead and reboot. 13. Once you are back in Windows run the Driver Signature Enforement Overrider software again and choose the "Sign a System File" and click Next. Now it will ask you what file to sign. Enter the file name that you want to sign, which is the atikmdag.sys file (It is requesting the whole file path, i.e. C:\Users\SIRacer09\Desktop\atikmdag.sys) 14. Enter the file path and hit next, then reboot. 15. Move the atikmdag.sys file to the c:\windows\system32\drivers folder, overriding the one in place and reboot.
When your computer comes back up, you should (hopefully) be good to go with the new atikmdag.sys file and flashed GPUs. Again, this is a rough outline of what I did. If you have any questions, don't hesitate to ask. Hopefully I can help!

which driver version you are using
Thank you, I am next to acquire these days 2GPUS 8GB Gigabyte RX480 unfortunately in my country Peru , do not reach the XFX or Saphire , only MSI and Gigabyte and are around 320-340USD .
I see the possibility to import them , but leave as expensive , not much difference .
You that you suggest , the Gigabyte would yield the same? It lei, would function with the latest drivers .
EDIT: which level do I change?

"Try this one Marvell, 29Mh otb, low power usage "
My System is running Win10 Pro on ASROCK H81 BTC Pro /Celeron1820 /G2 1300W PSU or a cheap EVGA 600W PSU for my ROM testing station.

Can you share how to flashing in Windows 7?

This is what I did
1. Deinstalled drivers via DDU
2. Flashed low energy ROM using Atiwinflash.exe from cmd mode with administrator ownership using command atiwinflash.exe -f -p 0
3. disabled driver signing check on Windows 7 x64 using these commands from command prompt with Administrator privileges:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

4. Installed latest 16.8.2 drivers
