Polaris Bios Editing ( RX5xx / RX4xx ) - Page 112

post #1111 of 3309
Problem solved! Here's the release note of 12.2 "Radeon ReLive may fail to install during installation on some system configurations".

From 470D to 470, I flashed a native 470 BIOS without modifying,and installed the 12.2 version without any cracking.

There is no native 460 with 1024sp so 460 unlockers still need patching the driver.

Which bios did you use? Btw, if it an original bios from Gygabite/Shappire/ it will work, the driver mod is needed for user modded bios (with no signature from AMD)

The AMD Pixel clock patcher download page mentions that:

Are BIOS modders here ok with this?

from XFX 470D Black Wolf to XFX 470 Black Wolf

Black Wolf is for Chinese market only, but looks like RS Black, maybe they are the same in fact.

You did't needed a modded driver since you used an original XFX bios, so it's signed by AMD.

You guys need to understand the difference between bios modded by us and by aib parthners, like XFX, Asus, Shappire.

Every bios has a signature by AMD, the signature can be done only by AMD and it's "unique" for each bios file. If you change the bios manually the signature is no more valid for that bios, and it can't be computed from the old signature or from scratch (except AMD). Aib partners can mod the bios and ask AMD to sign the new bios, we can't. The original AMD driver cheks if the sign on the bios is valid, if not the driver itself stop to work.

There is a lot's of IT_Security/Modular_Math/Possibly_Elliptic_Curves/Digital_Signature theory behind what i juat said, ask google for more details, ... or follow "some" it sec./math class (cries in math)

Hi, I have a Red Devil 480 8gb.

Would anyone be able to post an RX480 bios that has the legacy boot portion of the bios removed?
The reason I need it is to allow me to boot my hackintosh with the IGPU disabled.

Apparently if I select CSM on my motherboard my GPU won't be posted at BIOS. That is exactly what I want.
When I need to access bios, I can then just switch to the other bios on the card (dual bios).

Many thanks

Rhys

Thanks for explaining, but ……of course I already knew that from the beginning, that's why i said is's necessary for 460 unlockers to crack the driver.

I couldn't even install the 12.1 driver, now solved, here's my post http://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460/1090#post_25713804

We're all broke possibly just as I am but the rx 480 has an incredible Reference Blower 8GB sale @ 179.99... anyone cares? I could supply a link. thumb.gif I plan on going to compare the ultra rare reference blower r9 390x 8gb & reference blower rx 480... I have a Gelid and Accelerto Xtreme laying around for these cards as reference has that special cooling "frame" that non reference do not. thumb.gif

So since custom bios are dead without mods (don't want to mod driver kernels), are there any reference compatible bios that have a higher power limit? I'm running a visiontek reference card and 50% power limit just barely passes me for stock because it's got such a high leakage ID =\

Go here there are quite a few with 140w tdp and some with 50 instead. Open them up in Polaris boos editor to check
