Ok so I'm about to receive my 4GB RX 480 in the mail tomorrow, I read this entire thread + some others I found online, because I can't have hardware in my pc that isn't absolutely pushed to its limits. I'm aiming for 1.275v - 1475mhz core - 2000mhz memory.

From what I understand this is what i should be doing :

1- Remove all old amd drivers
2- Shove RX 480 in my rig
3- Install newest drivers
4- Backup RX 480 bios using atiwinflash
5- Adjust RX 480 bios using polaris bios editor 1.4
6- Throw new bios on RX 480 using atiwinflash
7- Swap atikmdag.sys with the modified one
8- Sign modified driver with dseo13b.exe
9- Overclock using the latest Asus Gpu Tweak 2


Am I missing anything?

I've had a pair of HD7850's running in crossfire 1290Mhz on the core for four years, I think I'll manage this too. Update tomorrow on results.

Card I'll be using : http://xfxforce.com/en-us/products/amd-radeon-rx-400-series/rx-480-rs-4gb-dd-rx-480p4lfb6

I'd move step 7 up to step 4. I'd also add the step of putting windows into testmode and the optional step of removing the watermark.

If you can't get step 7 and 8 to work no point in modifying the bios.
post #555 of 3331
but if I don't have a modified bios first i wouldn't know if step 7 & 8 are succesful, as I understand it, drivers don't load with modified bios unless those steps worked out.
can you explain optional step removing watermark? i probably missed that.

@chikatilo

The drivers wont load if the driver test signing is unsuccessful. If sys file is in the correct place and you don't accidentally have another copy in system32 rather than system32\drivers as I did the first time and it's signed it will load. I did accidently put it in system32 instead of system32\drivers over the existing file and the driver fails to load until it's signed but it doesn't fix the bios issue because it's still using the unpatched file in system32\drivers as well. Only put it where it actually prompts you if you want to overwrite it or it wont work. Having an extra copy under system32 may also make it not work. If you can't get the driver patch loaded properly, the drivers will quit working when you get to steps 7 and 8. That's how you'll know you failed and it's pointless to flash. You don't want two possible causes of failure. The BIOS and the failed patch. If the test signing and entering test mode aren't successful, Windows won't load your display driver. Once you are sure you have the procedure for the driver patch down and working you can switch it up and patch after flashing the bios. But I recommend getting the patched drivers working properly before you flash your card at least the first time. I've had failed flashes toast cards and motherboards and even televisions. Why risk your card until you're pretty sure you can actually use the BIOS. Just saying. No reason to risk your card until you're pretty sure you can get the patch working.

In test mode there's a watermark in the corners of the screen. Similar to the Safe Mode watermark. Google can find ways to remove this watermark. Just remember it removes the watermark for Safe Mode too so you have to remember whether or not you have the check mark in safe mode in msconfig.

Polaris Bios are signature protected and cannot be modified unless the bios is re-signed at AMD server.
-WAIT FOR FIX-

WITH NEW 16.9.1 YOU DON'T NEED TO PATCH OR SIGN ANYTHING. THEY WILL WORK WITH MODDED BIOS AS IS!!!

Confirmed! With a RX 480 Red Devil and my Reference Card.

But there is a Problem. When you edit the bios the Cards will be limited at 110 Watt mad.gif
