RX480 or flashed 580?

[Deuxez]

I bought an old XFX rx480 RS 4gb some time ago. now the card itself has a Bios swithc on it, and the previous owner had flashed it to an rx580. But he helped me swtich back to normal rx480 (basically just flipping the switch.) Now im wondering if i should stay with the normal rx480 or should i switch it to the flashed rx580? I noticed i had some problems when i had the rx580 bios but that was probably cuz i was trying to install rx480 drivers on it.

flashed 580 gives higher power limit, more voltage and potentially less stability (it's 480 silicon after all, not as well performing as 580 silicon). I'd use 580 bios and tune it properly

Does flashing incorrect BIOS onto a GPU have any distinct benefits besides scamming people you're trying to sell to? 

 

I'm not familiar with this as an upgrade path for any hardware, since your hardware is what it is, and BIOS can't change it. 

 

Mark me interested to see what comes of this.

So u recommend the rx580 bios cuz it gives more power etc but less stability? What do you mean with less stability? u mean like crashing and black screen etc?

AMD drivers come in a package, all GPU's back to the HD 7000 series are in there, there's no specific RX 480 driver or RX 580 driver that you can download.

I say if the RX 580 BIOS is unstable then just don't use it, stability is more important than performance and you can still overclock with the RX 480 BIOS so it's not like it makes that huge of a difference.

because RX 400s dont clock as high as RX 500s, it's the whole point of 500 series coming out. Just more power and voltage to a 480 doesnt make it clock as well as a 580 which means when you flash a 580 bios, it might default to frequency that are at the edge of stability. 

 

By tuning, I mean adjusting the frequency offset and maybe power limit and voltage with OC software like Afterburner or Wattman. It would be great to know which RX 580 BIOS your card is currently using, this way I can check if there are lower frequency RX 580 BIOS you can use.

it does allow more overclocking, the XFX RX 480 RS has a decent PCB.

Cool! Thanks!
