But there is a Problem. When you edit the bios the Cards will be limited at 110 Watt mad.gif
Can you post a proof of such limitation? You have larger power limit in bios but new driver starts throttle above 110 watt nevertheless?
Rizing Power Limit via WattTool (Wattman) didn't help?
Did you try "Current scale" hack in WattTool?

-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!!!
Yep. Works on any RX card!
They even fixed GPU underclocking bug!

Yeah, they did, but the performance isn't better than with 16.8.2.

For example, lowering vddc to 862mV will cause the system to crash in an instant, even higher it crashes.

With 16.8.2 my card has been running rock sold and stable at that offset for over 36hrs.

Can this work on custom RX 480? Particularly the XFX RX 480 GTR Black OC. I need it to be able to get more voltage.

Its confirmed in our German Overclocking Thread ->

The Driver will limit at yorue Stock Powerlimit, Current Scale i dont have tested allright but this Option isnt good because all Security Features will be disabled.

So dont wonder if youre Card go up in Smoke.

With Regards

I can confirm you don't need to sign drivers anymore or whatnot to run with modified bios, but even if you succesfully modify the bios to shove more juice through the card, overclocking software won't let you actually raise the voltage, drivers blocking you from doing that seems likely.

My xfx card came with a limit of +20% pwrlimit instead of the +50% every other rx480 seems to have, I was able to unlock that to +50% (or change any other thing I want) but not voltage.
Guess I should have bought the 1060 after all, 7850 was the best overclocker I ever had, rx480 the worst.

Overclockers proving an overclocked 480 beats 970, 980 and 1060 is good for amd, I don't see why they would go out of their way to prevent us from doing that.

The amount of power required (and pulled through the motherboard) when overclocking even higher probably has something to do with it.

I'm trying to edit my bios using Polaris bios editor but it saves it as a file with a size less than 512kb. As a result the card gets bricked. Is there any workaround? redface.gif
