Would anybody have any info on how to modify the maximum voltage on the Sapphire RX480 Nitro OC (8GB)? I've gone over all the details in OP, even tried to identify things using the custom 1.4v "unlocked" bios, but my hex skills are pretty much non existent. I know enough to follow instructions, do the edit, and whatnot, but to actually find the offset where the voltage is located, that is a whole other ballgame.

Basically, I want to put the voltage from the stock ~1.26v to 1.5v, as it's under water, I want to see how high it can clock. I would really like instructions, or if you have enough experience, modify the bios for me. I would be very grateful for any of this.

Currently the max I can do is 1510mhz @ 1.245v (as completely stable) and 1530 @ 1.26v for a single firestrike before it crashes. I need a little more oomph to get past this hurdle.

Cheers,
Jeb

I am in a fix as I ahve bought 7x Sapphire Nitro+ RX 480 OC 4GB cards with the hope of mining on Ethereum with them. It seems that out of the box they use considerably more power and mine at lower speeds that indicated on Cryptocompare.
I have seen videos describing how to mod the BIOS the RX 480 8GB to mine Ethereum faster and using less power. like this one-
https://www.youtube.com/watch?v=Mwb67g4skGM
My problem is that I have a 4GB card and the suggested timing mod in the video I saw does not relate to what I see when I open Polaris with the file I read out.
I am reasonably competent however new to GPU based stuff. Can anyone offer any pointers, guidance or even help with generating a modified rom. I have looked around quite a bit but am loosing what little hair I have.
Any help greatly appreciated. smile.gif

I searched quickly through this thread and didn't see anyone testing this on a RX 460. I have a Sapphire Nitro RX 460 4GB and this is what the bios editor shows:



Strange TDP and core voltages

Both ATIWinFlash and GPU-Z give me a 256KB bios which gives me a warning in the bios editor about not having the standard 512KB.

I heard that it is best to use ATIWinFlash to read out the ROM as GPU-Z generates a small file. So perhaps it is safer to use this one. It sounds like the ROM on the 460 may be smaller but I am new to GPUs so that is a guess.

¿By any chance does anyone here has the Sapphire RX 480 Nitro+ OC 8GB SKU 11260-01-20G? I need the boost vbios the 1342mhz factory vbios backed up with atiflash (e.g backup.bin 512kb file size)
I will be very grateful.
this is my card https://www.techpowerup.com/gpuz/details/n7h55

Or does anyone having problems with the card sitting at 300mhz and the gpu z showing 0 mhz and unknown pixel rate and texel rate i wolud be glad to hear, it fixes alone from time to time but it's really annoying ¿maybe the stock bios that my good friend jeb101 passed me was faulty? either way ¿has anyone encounter this issue?
