[UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing

[jmumich]

Heliox - if the power saving friendly version for Windows available yet? I have Sapphire 480 8GB. Thanks!

I am tempted to use the full-power version, but I just busted a breaker the other day and wouldnt want to take the chance...

I think this is it: https://bitcointalk.org/index.php?topic=1584617.msg15943054#msg15943054

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?

read the previous post and give it a try

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

100% fan speed must be noisy though..

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

Dam' no Win7 support.

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

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...

[mikhan]

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?

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

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

Dual mining is only producing 23 & 350ish MH. However, solo is producing 31. Claymore is only reading the card as a 4gb. Am I doing something wrong to get such low dual mining?

that does not sound right you should be getting at least 27-28 eth and 400 sia, the whole point of dual mining is to keep close to max ETH hash rate and mine SIA as a bonus

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

[Marvell1]

does this mod work for 4GB ref cards ?

[Marvell1]

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 ?

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?

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

29Mhs and low power - sweet music to my ears - will try this out tonight

[nhando]

Does this ROM work for all Reference RX480 8GB cards?  I see some reference to Powercolor not working?  Also what is the latest tested Step by step process to get this working?  I see quite a bit of trial and error from the history but I'm not sure which 1 is the best practice to follow by after all the experienced gain from the testing.  Thanks.

eth only is 31

Which version of the drivers are you using?

Here's what I'm seeing after flashing https://i.imgur.com/fF4po8D.png, unsure why no temperature are being reported - it's a stock powercolor rx 480
