Sapphire 390X Bios?

[brainlessgaming]

Hello!

Does anyone have a link to a Sapphire 390x bios? I have a Sapphire 290x and want to flash it to a 390x bios, but since I have a Sapphire custom PCB, I need a Sapphire 390x bios. 

Also, if you have a Sapphire r9 390x, could you please upload your graphics card's bios? 

Thanks!

It won't work AFAIK, it's kinda more than the same as the 290x, it's a rebrand but not the same thing at the same time

Yes, but I could mod the bios so it would work with 4gb of VRAM and I could lower the memory clock.

The BIOS you flash does not matter, the only difference would be the default clock speeds and voltages

Which is extremely hard if you don't know how to write the code without bricking the card.

that's why we have a dual bios switch

Even if my card has a custom PCB?

isn't there software that lets you edit the bios?

Not really, You would have to write the code yourself, AFAIK.

yes

isn't there software that lets you edit the bios?

yes

 

wost case scenario you have the dual bios switch

 

If it works post back with GPU-Z screenshots with before and after, post back with benchmark scores before and after, post back with gaming performance before and after

upload your modified BIOS and post a link to it

 

If it doesn't work, use the switch and post back

anyhow, good luck with it (:

Do you know of any tutorials on how to use the software? 

Also, when I power down the PC, I know that I have to switch the bios to a certain position or something. Since I have a Sapphire card, it has a physical button. So when I power down my PC to flash the bios, would  I push the button so it is glowing blue (UEFI mode) or just leave it as is (Legacy mode)?

Never had to use one, never used one.

But looking at the screenshots it seems to be a pretty straight forward user interface

 

Alhtough a funny thing I noticed:

Due to a digital signature requirement on latest AMD cards, RBE is no longer in active development and will not support the latest graphics cards.

 

And the last supported GPU on the list is 6970

 

 

I would use this guide as a refference on how to proceed with the bios flashing:

Another bright article showed up:

http://www.overclock.net/t/1561278/amd-r9-290-290x-flashed-to-r9-390-390x

 

Man those guys at overclock.net are reckless, nothing like some people on some forums that go on yelling that flashing VGA with different BIOS is imposible and calling people names for asking about overclocking USB...

what is RBE?

Radeon Bios Editor the thing from techpowerup.com

 

maybe you should look around if there are any other offers for bios editors on newer cards or just look for any custom bios linked in that overclock.net thread

Yeah, i'll have to look. However, this guy did use it to mod his graphics card bios. Then again, it was a 6970. 

@MEC-777 linked me to this modded 390x bios: https://mega.co.nz/#!dU4AxRLI!zpCi2P-ybfy2ZxkQJ5TM0noSSSv7QoQD1KPvAVt1UVU

However, I have been reading through forums and people have said that if you have a custom PCB, then flashing the card wont work. You have to have a reference PCB. That's why I wanted a Sapphire 390x bios. If this is not true, i'll use the bios that I was linked to.

What cooler you have? At that speed it may not be able to run properly!

I have the trixx cooler

Not to sure I would trust that cooler after ASUS had some 290 failures but if you feel its good then you can try...

the bios flash on reference cards is just more likely to work

I suggest you try the one you were linked to

Yes it does matter. The differences in the BIOS between 290's and 390's is more than just clock and voltage tweaks. They've altered more than that. The proof of this is in the fact that with my 290 flashed to a 390x, I have observed 3-5% improvements (in benchmarks and gaming performance) clock for clock with lowered voltages and the card also runs a couple degrees cooler. So they've clearly made other optimizations within the 390's BIOS. 

 

Not to sure I would trust that cooler after ASUS had some 290 failures but if you feel its good then you can try...

 

What does Asus have to do with Sapphire? They are completely different cards made by different companies with different cooler designs. The Sapphire Tri-X 290's are widely regarded and known to be one of the best 290's on the market and have one of the best coolers (among 290's).

That one may be good! But look at the temps!

Yeah, look at those temps... Coolest running 290x out of all those compared in this review: http://www.techpowerup.com/reviews/Sapphire/R9_290X_Tri-X_OC/28.html
