Will you please stop repeating this nonsense for people who don't know better? Polaris as it is now couldn't reach those clocks even under LN2.

I think you might be unto something. I'm a rather skeptical person, maybe that's why my card won't clock better. I'll try a candlelight vigil this weekend teaching.gif

@Pavoz Looks like your bios could use some more rpm... 10 minutes was cotinuing to rise 85 degrees Celsius... Check out the VRM Temperature? I'm sure it must be 25C higher... Stock Hotspot what 109C? Just a thought.

@Loladinas I guess im too judgemental, the card is of great value... Maybe though if they make it thermally cooler by 50C vrm/ core? $50 more expensive it would be even more desirable? Or would 50C be $100 more? $2 per every 1 degree celsius cooler core/ vrm? I mean if it's actually doing that... that's what I wanna buy.. I'm sure others would pay for top quality cool running hardware...

It would be like yes it's $299 entry but it's 2x cooler.... truly really is 2x cooler running...

Doesn't work for me... (nitro rx580 8Gb on nitro Rx 480 8Gb)

Haven't time to try more, but atiwinflash says something like "error with subsystemID"

Is it possible to "force" the bios update with atiwinflash?

Well, you could, but are you sure that's a good idea? Those cards have different PWM controllers, different MOSFETS, different phase count, and different VRAM chips.

EDIT: as I understand after my limited reading, the only benefit of flashing would be the new p-state for multi-monitor and video playback?

Done !



I follow those steps and have now a RX580 lol...

I edited Rx580bios with polarisbioseditor, to lower core clock as my card can't stand more than 1370 with +50%power and + ~50mv.

Then have follow the link above to flash it and it works. My screen flickers a bit after restarting windows (pretty sure because I left core at 1400), but it stop after 5-10secs on desktop.

Will try now to test some benches / games to see stability and temps...


PS : thanx for the link, I saw it too late tongue.gif


EDIT : do not flickers anymore at windows start with base clock (1342 core, the nitro+ boosted one, edit with MSI AB)

I don't recommend anyone flash the RX 580 bios to your RX 480 yet, there are still quite a few tweaks need to be made first before it's fully compatible. If you already have it on there and had 0 issues then that's awesome.

Here's a comparison of some things different. The main primary best thing about the RX 580 is power savings but also more pronounced core voltage for clocks in the 65288 value. Meaning basically slightly higher voltage for more stability by default in 65288. Also the fan is more responsive and much quicker to spool up to speed than RX 480 Bios. Also RX 580 idle voltage is 750mv, RX 480 is 800mv... This can cause issues but I think the primary issues are in the incompatibility of memory timings between I suppose maybe my card alone "Reference RX 480 8GB" or others?

Will need to do some tweaking testing to get it stable. Maybe some of you Timing Gurus can chime in explain/ try to understand where "Stock RX 480 Reference 8GB" timings would go in the RX 580 bios to make it more compatible?
