I'm not sure what I'm doing with the bios editor. Will someone take a look at that and let me know if it's possible to change the max voltage to 1.2/1.25, up the ram limit/max voltage slightly, and change/tighten the timings for the ram? I'm really apprehensive to do it myself so any help would be much appreciated.

@comagnum, Thanks for uploading the Bios
and for all the XFX RX 480 owners..... i used the Bios from comagnum and it worked with no problem on my XFX RX 480 8 gb card

The good thing is that it saved me 20 € so i´m , glad i didnt buy the @1328mhz overclocked edition because know i have it for free

Wonder if that would work on my XFX 4gb card. I'm currently running the 1266mhz 8gb bios on it.

Edit: Can confirm this runs fine on the 4gb XFX card. I'm using it right now with no issues.

The bios you posted is unmodified? if not can you post it? Thanks

EDIT: Tested. Working Fine. thumb.gif

The Driver Signature Story is not good, no voltage Mod possible sozo.gif

Now we must wait for Afterburner, and hope there is no limit @ 1,15v tongue.gif

On current RX 480 ref PCB you can gain more VDDC by using this command switch on a MSI AB shortcut :-

/wi06,08,8d,xx

xx denoting the hexadecimal multiplier for SVI2 voltage step ie 01h = +6.25mV, so for say +100mV you would use 10h and command would be:-

/wi06,08,8d,10

If you wish to reset back to stock you can send command:-

/wi06,08,8d,00

Prior do doing above I would recommend either an i2cdump to verify IR3567B is on bus 6 device 8. To do an i2cdump via MSI AB you add command switch -i2cdump to shortcut. Whilst dump is being done you will not see any indication on desktop that it is occurring and an OK prompt will appear at end, then you will find log in MSI AB install dir.

The other method to send i2c command is:-
Quote:
- Go to the installation folder of MSI Afterburner (where the MSIAfterburner.exe is located) and open a new command window ("Left Shift + Right Mouse Click" when no file is selected)
- Additional step: Verify that the I2C interface to the VRM controller is working by typing following command: "MSIAfterburner /ri06,08,0D" (without the quotes). If the response is ": 20" or ":44" you're good to go.

Then send commands for VDDC offset as above.

Be aware anyone using this command all DPM states get a voltage increase (ie idle to highest state). You will see VDDC in GPU-Z monitoring / HWiNFO alter, I would advise send i2c commands when such apps are not monitoring card.

I have tested this on 1 card that a friend owns, so use information at your own risk..

The stock ROM/MTP configuration of IR3567B from i2c dumps I've viewed has no VDDC limit for offset, so double check i2c command you send as error = bye bye GPU. I have verified this with The Stilt, see linked post.

You can set a voltage limit so even if you make a mistake with offset command it will not go over that.

/wi06,08,3d,5f

Above command sets 1.36875V as limit, further info on VMAX feature in this post of Hawaii bios mod.

You guys lucky you can find the 4GB versions, here only 8GB and the prices are hiked.

This BIOS worked great for me! Was running 1288 with stock BIOS and now I have a free upgrade to black edition smile.gif Now onto benchmarks and voltage tweaking!

Memory voltage control in Wattman is "dummy" feature. The voltage control chip IR3567B has only loop 1 used from what The Stilt has stated, ie controls the 6 phases to VDDC (GPU core). Unless a revised ref PCB is done or AIB PCBs get setup differently there is no memory voltage control via Wattman/ROM/i2c AFAIK.
