Polaris Bios Editor spotted in the wild. - Guru3D.com Forums

Could be handy if they ever add bios switches to the cards;)
 
I'm curious why do people edit frequency / fan speeds in bios and then flash rather than doing it in any software like afterburner?

not only what TheLAWNoob said but also to prevent exactly the utilization of software. the changes permanent and less prone to bugs, I used to have a bug with afterburner and my old 280x card that sometimes the fan would stuck at the selected idle fan curve for example, the card used to idle at 30% fan speed so for any reason if left the machine idle for too long the fan keep stuck at that speed until reboot, and after the introduction with the fan speed bug with Crimson driver, sometimes with afterburner the fan would go at a crazy fixed speed randomly depending on the task. so, setting a Fan curve in bios allow to use afterburner without the need to set the fan curve there so avoid bugs.

Also apart from that depending on your card and brand you can set a desired base frequency that would prevent some cards from throttling, you can eliminate boost clock, you can set higher base and boost clocks more detailed with the edition of the power tables, as example as is in this topic, someone with a RX 480 could set the base clock as 1266mhz and force the card to have that constant speed without software dependence on fan speeds/power targets and etc. and the list go on, there's way too much benefits from BIOS editing..
 
Tying frequencies to voltages and 300mhz idle mem freq to specific voltage - can this be done on hawaii too?

nope, tonga and above.. so tonga, fiji and polaris which are basically the same.

Actually I believe it can be done on the "refined Hawaii" which was used in the 390/390X since AMD added multiple stepped power states in those cores, I think its Grenada IIRC?
 
I think it is possible on all hawaii chips, i am looking at HawaiiBiosReader app and it has something similar. Going to experiment when i go home

yeah is possible, is your card one of the latest revision?.

yeah it's possible, however I think the refined models are all based on manufacturers preferences, being the Refined 290X/390X sapphire the best option, is possible indeed.

I have an older ref card with a Gelid cooler on it but the reason i dont use 1500+ mem clocks is because it is fine at gaming but glitches out at idle. This bios thing should solve that
 
A temporary fix for the excess PCI-E slot power draw for the reference RX 480 cards

if this guy can lower the draw on pci-e I am sure amd can too. He has already shifted it to PCI-E connector. Now the flashing tool is available so those who are interested can have a go at it. If he can do it I am sure AMD is already doing it as well. May be they are just making sure the default clocks are capped at 150 with drivers. Bios can shift any remaining load to 6 pin.

AMD should send that guy a few cards just for the community effort!
 
He isn't just some guy, he is a well known Bios modder for AMD cards with a ton of insider info.
