"Flashing" bios for 290 P

[funt]

So .. how do I do it? More over, can I do it?

I have: 1 x HIS 290
1 x MSI 290

Both are reference models, are they eligible to be "flashed"?

Right now I think I have hit the limits as any more added to either memory or core clock causes black screens and crashes and artefacts.

Will flashing the bios to unlock the voltage allow me to go a bit further? If so, what bios do I use and how likely am I to balls it up? That's kinda my thing ...

Thanks.

What's the max stable clocks you are able to hit at the moment?

Personally I think an Asus 290x bios would be better for unlocked voltage.

Use ASUS bios.
Make bootable USB drive
Download latest ATIFLASH add this to your drive, add ASUS 290 bios also.

Boot from USB drive.

At command prompt type.
atiflash -f -p 00 asus.rom for first card
atiflash -f -p 01 asus.rom for second card

At the moment the highest I can go before artefacts and crashes etc 1080/1300 but my highest score in Heaven and Valley was with 1080/1265. Anything over 1300 on the memory and it just says "Nope" and crashes and I have to force a reboot.

What are the dangers, if any? Can I ruin the cards by doing this? I presume doing this would void any warranty also?

Thanks for the help.

If anything goes wrong just flip the bios switch, that's what they're for.

Although it's unlikely anything will go wrong as long as you do it right.

Just save your original VBIOS with GPU-Z before you do it, so you can always go back to stock VBIOS if you want to, in cases like you need to RMA the card for example under warranty. As others have said you have 2 VBIOS's on that card so you just flip the switch if anything goes wrong. You can even reflash a graphics card that has been flashed wrong by sticking a second graphics card in that works to boot up and flashing the bad card back to a working VBIOS if it doesn't have a dual VBIOS. Risks really are low if you know what you are doing when things go wrong but as you see it's fixable.
