What I would like to know it's the importance of a power connector.
Do you think I can flash a 6-pin RX560 bios into a 6-pinLESS RX460? (same AIB, same memory and same number of fans)

Technically speaking, you can. It just wont run. The BIOS is totally different, there are various reasons why you should only flash same model GPU onto another one. I wouldn't flash a RX560 single fan on my RX460 dual fan. I just asked someone for help, he helped with unlocking the RX460 and thats it. Way better.

Guys, is there somewhere the list (or even links to multiple documents/posts/infos) with all the differences between the 4xx series and the 5xx series? Apart from improved architecture, I'm talking about all those thing that could be "ported" like the 1000 MHz memory step (I ported it to my RX 480 Nitro+ OC bios, seem my forum sign). My first project was a "480 to 580 conversion", since there are so much differences between 4xx/5xx PCBs (or at least of the card that I care), I prefer to maintain a 100% compatibility by using the original bios (and getting more performance), and "modding the hell out of it" biggrin.gif

I'm interested in "new algorithms"/"power saving features"/..../... basically all those "extreme" features that really translate to tweaked values.

I'm still using your gigabyte aorus 580 where I get 2020 with no errors and perf increase. But I noticed that the bios has problems with keeping the voltage like I set on PBE. [email protected] but in games, benchmarks etc it never actually reaches 1180. Most of the time it is around 1160/1170 and it gives me stablity issues. Power limit in Afterburner is set to 50%. What could be the issue?

pls change that huge quote to ".." wink.gif

there is a simple answer to it. it doesn't work anymore. since 17.4.1 u can't change the pointers (6528x) to a precise value.

What card do u have? some of the roms already have the 8D register for an offset, u can change it with a hex editor. the powercolors have it, the nitro, and the reference stock edition.

with the stock aorus 580 bios it was overvolting, so [email protected] it sometimes overvolted to 1190-1200 and I had no problems with it.

with your new aorus bios it is undervolting, giving me stability issues. [email protected] it is 90% of the time at 1160-1170.
card is xfx rx480 gtr xxx edition

version 1.1006? it is based on a newer version found at tpu. my mods work, i did an i2c check, all was fine. but if u say u have issues, i take it offline. i just don't had the time for testing.
