flashing bios r9 200 to 300 series - posibru?

[Kristijonas]

Or imposibru?

For example R9 285 to 380? http://techreport.com/news/28231/official-specs-confirm-300-series-radeon-rebrands

I thought 280x is rebranded into 380x but apparently 280x has a different memory bandwidth? http://www.hwcompare.com/29485/radeon-r9-280x-vs-radeon-r9-380x/

280X and 380X are completely different cards with different GPUs. 380X uses the full version of the chip in the 285 and 380.

285 = 380 = Tonga Pro (now called Antigua Pro)
M295X = 380X = Tonga XT (now called Antigua XT)

All of the desktop 300-series are rebranded models of previous GPUs - some 2-3 generation old. Only the Fury X/Fury/Nano are new.

Why are you trying to flash it?

I am assuming flashing a card to a rebrand would offer the latest version of opengl and directx.

So in theory R9 285 could be flashed to R9 3xx ?

If the cards are functionally identical wouldn't they already support the same versions of Opengl and DirectX based on drivers? The only reason I've seen to flash one card to another in the past is to possibly unlock additional "hidden" shaders on a cut down gpu in the same line.

 

[Kristijonas]

hmm I though opengl and directx support is imbeded somewhere in the gpu bios itself which is the reason for example 4850 cannot support directx 11 or 12.
So anyway, I wonder if it's possible to flash any of those r9 200 cards to r9 300?

The 4850 cannot support DX11/12 because it lacks the hardware support. Doesnt matter what BIOS it has on it.

No...

No, DX and OGL support depends on the GPU itself, not the BIOS. The BIOS holds frequency and voltage tables, memory timings, and a whole lot of things that make the card functional instead of a pretty paperweight, but don't determine in any way what DX or OGL version it supports.


Anyway, should you flash a 200 series card to its 300 series equivalent and the card boots, you'll gain a name change, and that's it (still not getting a 300 series card out of the process, there are other things changed that you don't have control of).

Some cards (Hawaii based -290/390/x-) allow for some interesting BIOS modding if you're up for it. For the rest there isn't much info available I think (or I haven't bothered to look for). Some other cards (Hawaii, Fiji based) can unlock shaders if you got lucky enough with your purchase.

 

[ShintaiDK]

The only thing you could possible get out of flashing a 285 to a 380 would be a slightly higher boost clock (918 to 970). Easier just to manually OC if that's the case.

 

[Mercennarius]

Just overclock your R2xx card and you'll be on par with an R3xx card.

 

[Kristijonas]

Thanks for your answers! I don't suppose there are any mods/unlocks/bioshacks for my 270x ? ;p

270X is a full Pitcairn, so nothing else to gain.
