Download the tool i made and run the batch file will do everything for you to make your card a R9 280x

The bios I include is the one from the msi R9280x gaming edition which is working on a powercolor 7970.( should work on most REF design cards)

Just make a backup of your bios with gpuz before hand, then you can flash it back if it fails to boot , by replacing the orig.bin file with your bios file.

The 7970 has dual bios so if it fails , just boot from the other one.

Thanks! Will give this a shot later.
 
Bleugh, multiple monitors don't work for me under the R9 BIOS. Revert.

Any noticeable increase in FPS from the flash in your games?

Also did it affect your overclocking for better or worse (if you overclock) after the flash? There is a compatible bios available for my 7970 Ghz Sapphire Vapor X and I'm pondering if it would be worth the hassle. (My card is already overclocked to a stable 1150 1600 without any voltage increases).

now another quick question...seeing as the 7950 is also 384 bit card that's little detuned from what I see.Does the 7970 and 7950 show remarkable difference from one another?

Take any review of the HD7970. Now minus 10% from the scores on the HD7970. That's how the HD7950 performs on average.

Note to anyone flashing a HD7970 without a dual BIOS switch and using a BIOS from the new reference models - you can quite easily brick the card if you're using the wrong version. AMD changed their standard video ports and switched things around to make Eyefinity work without Displayport. If you want to flash (and there's literally zero reason to, you'll just get lower performance) make sure you use the BIOS from a 280X with an IDENTICAL video port configuration.

Don't flash it, you'll just limit your card and the overclocks it can reach. Stick to your stock firmware.

same overlclocking for me , still runs at 1150/6500 , 1200 core is still not stable , max around 1175
 
So I was bored and seeing that my card has a dual bios I decided to try the R9 280X Sapphire Bios a spin anyway.

Works perfectly and still maintains my stable overclock at 1150. Max core also seems to be 1175.

Currently using the Win 8.1 Beta drivers and will test it extensively over the next couple of days/weeks.

Edit: Interestingly after running 3D Mark Firestrike my scores, with the same overclocks, improved from 7802 to 8097.

This has highlighted my potential need to "finish" my upgrade.
My Fire Strike score was at 6111. This is a dramatic improvement from the 3087 with my 5870, but a far cry from your scores.

I know my PC's innards are dated, but didn't think they would have THAT large of an impact...

Lol and there are scores much higher than mine with the same setup. My 3770K is only overclocked to 4.4 while 4.5 seems to be the norm looking at the other 3D Mark scores.
 
Right so now it's decision time....I know I will see a HUGE difference from 7850 to 7950 but is the difference really that noticable between 7950 and 7970?
