I installed the 16.12.1 ReLive Win7 driver for my RX480 again.
The importent part is to copy asder00's atikmdag.sys in this folder:
c:\Windows\System32\drivers\atikmdag-patched\
Run the atikmdag-patcher.exe and reboot.

Does anyone know if this custom bios issue will be fixed again in the near future?

All overclock, all the time

I don't think its an issue but rather intentional decision from AMD

So to make it so it works everytime without disabling driver enforcement, this must be done? Copy modded atikmdag.sys in this folder:
c:\Windows\System32\drivers\atikmdag-patched\
Run the atikmdag-patcher.exe and reboot..... Yeah that does the trick haha... theres a whole bunch of files in atikmdag-patched.. anyway

Now I have lined up 1385mhz performance on stock 65288 @ 1310Mhz... Pretty neat.

Crimson ReLive 16.12.2 are out, and custom bios still don't work.

asder00 we need you for the custom atikmdag.sys

I'm not asder00 but...

Based on asder00 and lordkag work, all credits goes to them.

Modded 16.12.2 atikmdag.sys that allow modded bios: http://www.mediafire.com/file/1qb1w71kabj1cin/atikmdag.7z

Follow the same process for 16.12.1 (https://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460/1050#post_25699216), but use the updated kernel file.

Bought a XFX RX 590 Fatboy! Looking for IR 35217 datasheet! Selling my Hybrid RX 480 Nitro+ OC 8GB.

Working, thank you very much!!!

Btw, how do you mod the atikmdag.sys? Let's see if I can learn to mod it by myself tongue.gif

Sounds like we need to throw the driver enforcement patch up in a git repo

Thanks. You may create an HxD batch exploit script which includes HxD where you place the .sys file in the same directory and it auto-corrects the specific start-end hexadecimal offsets within seconds. Looks like 0000170D, 0000171A, 00001727, and finally 00001734... I'm sure it couldn't be difficult or time consuming... A bit of time learning of the ways of scripted hex-editing via HxD... thumb.gif

Massive thermal bottleneck at the core voltage regulators. Feeling by hand back of pcb, regulators are about twice as scorching as the core. More fan helps but without active heatsinks it doesn't do much even at 100% fan speed. Need front and back copper front-back plates with fuji xtreme 2mm 17w/m k. Artifacts occur because of regulator temperature, direct relation between core regulator temperature and artifacts and performance hits on the low and big end as high as 20% in spots. If the regulators held at no higher than 60C or more like 50C Test 1 could show between 37 to 40fps average. Which says this card is easily capable of pulling 2x ROP in fps... meaning 1 billion pixels is typically 1 frame per second... in other words on these cards 1 billion pixel's is more like 2 to 2.5fps rather than 1 on every other card of any manufacturer.
