Topic: [UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing - page 53. (Read 231045 times)

What is the speed when you mine the ETH only? Is that the same 27 MH/s or the 31 MH/s mentioned by the OP?

1: (while everything is at stock, so stock rom, stock driver) i execute this command first (as admin)
Quote
bcdedit /set nointegritychecks on

2: I reboot to safe mode(Hold Shift while clicking reboot) and i replace that atikmdag.sys file.

3: I reboot back into windows with that replaced atikmdag file. Windows should load perfectly, same for your drivers.

after this step all my cards show the error :


This device is not loading properly becase windows cannot load drivers for this device any help ?

does this mod work for 4GB ref cards ?

tried dual and get 27 eth + 400 sia with temps rising, so i mine eth only...

thanks a lot, i managed to do it!
the key factor is to enable IGPU or another card with stock drivers (some nvidia?) and make it first to initialize in bios
connect monitor to that card and load windows, you see that your rx480s are disabled in device manager
sign patched amd file with that tool, reboot, you'll see 480s are ok in device manager
connect monitor to a rx480 and reboot again
that's all

note: do not disable IGPU or stock driven card otherwise windows won't recognize 3rd party signed amd driver file. also if you leave monitor connected to IGPU or not-amd card, you won't be able to control and monitor amd cards (i guess you know it already, it's a stupid driver feature)

don't know if it is applicable to 6GPU system, my rig is 5x480 + IGPU
if 6GPU + IGPU work together so why not

update..
I managed to replace permanently atikmdag.sys in Windows7x64. Test mode and driver loads every time
All i need now is to edit bios...

that's definitely impossible, also i would not trust gpu-z, it miss the wattage from the pcie i would use a wattmeter or the corsair link for the corsair psu

Dam' no Win7 support.

Dual mining, eth at 31+ and sia at almost 400 and only consuming 70w..

Even with the core voltage down and Power limit at minimum, that's just not possible.

 

Plus, your image is just not clear mate, miner screen isn't fully on there, could have hit CTRL+C, screen will freeze but will stop mining, there's also another miner screen on the background..

You can easily take a real screenshot of your entire screen with more detailed information.

Perhaps you're an amd engineer with hardware that isn't available yet.. otherwise, nahh :p

Only 72W in gpuz, that's really nice!
100% fan speed must be noisy though..

Today. my work... with HIS RX480 ref
Thanks for your guild

read the previous post and give it a try

I think this is it: https://bitcointalksearch.org/topic/m.15943054

I've been running on Windows 10 and it's been stable. I still have to boot into disable driver verification mode.

Does anyone know a way to set up an auto-reboot so that it goes into this mode?

No.
- turn on the iGPU (set it to Auto if possible, so it's always disabled when you don't connect any monitors to it but enabled whenever you do)
- move your monitor to the iGPU (you might loose the signal on the discrete cards anyway and you might need to do this temporarily to stop the AMD driver from loading)
- have an AMD driver installed (doesn't matter if already "cracked" or stock but I will assume stock here)
- flash your cards with custom BIOS (if not already)
- reboot to Safe Mode to replace the DLL file with the cracked one (if not already)
- enable the Test Mode with bcdedit permanently for every regular boot (and keep it enabled indefinitely) and reboot
- sign your DLL file with the tool linked above (preferably while in Test Mode but with the driver NOT loaded, either due to signature problem or no cards connected, etc...)

My exact journey was like this:
- flashed the cards
- enabled Test Mode for regular boots
- rebooted to Safe More (note: not Test Mode yet) and applied the cracked DLL
- tried but failed to reboot into Test Mode (I ended up with a completely blank display, no life sign)
- moved the monitor to the iGPU and rebooted again into Test Mode (by default)
- I signed the cracked driver with the linked tool
- rebooted (yet again into Test Mode as always from now) and saw the AMD driver loaded
- I shut down Windows, move the monitor back to the discrete AMD card (for WattMan to work), booted (into Test Mode) and everything works

I searched the forum, it seems nobody knows. It would be better for the AMD friends to sign the BIOS for us.

secure boot is off of course in my system
so you suggest to enable IGPU, sign driver myself, then turn testmode off and that's all?

Yes. I found and started using this solution several years ago when I had troubles with an old notebook and this is exactly what I just did yesterday on the mining PC (and it worked).
SecureBoot could still interfere though, especially if it's a clean install of Windows 10 RS1 (the last update) which made MS signatures (*) mandatory for kernel mode drivers.
So, I guess you have to disable Secure Boot (sometimes "Other OS" means "disabled" in practice, so set it to anything but "Enabled" or "UEFI Windows").

* valid MS means WHQL is practice, it's not enough if AMD itself signs it but not MS (so, forget using your own signatures in that system).


The other possible trick in my procedure is that I flashed the card first and started to work on Windows later, so the DLL file rejected and this it wasn't loaded when I rebooted into Test Mode to sign it.
I am not sure if you can successfully sign in Safe Mode (I guess not but you can try) but you can prevent the driver from loading if you, for example, disconnect all AMD cards and use the Intel iGPU (if available). And that's what I did (I didn't disconnect anything but used the iGPU) because there was no output at all on the AMD card when it tried to boot in EFI mode without a signed driver.

So it looks like I'm not the only one having that issue with the Powercolor card any one know if its just that card that's having an issue or if you just have to change the sub-vendor ID or something?

Guys, can you say me the power consumption for each card with these settings, and for the whole rig, with RX480 i suppose ?

Interesting if it's profitable to try, thanks.

+1

I have PowerColor.

for Windows stopped this device because it has reported problems . (Code 43 )
