Can flashing your gpu bios yield better overclocks ?

Title says it all.

 

Would flashing my 290x with a "high performance" custom bios let me OC my card any farther ?

 

Right now , i am stuck at ~1140 mhz on core,

 

Asic quality is 70.5% , so i think it shouldnt be that bad , considering most people can reach 1150 with less than +80mv .

The only way it could help is by increasing the power target, but remember the silicon lottery can't be overcome.

 

1,140MHz is probably the limit of what your chip can achieve.

A custom bios will not make your chip run at higher clocks with lower volts. All it can do is remove voltage limits imposed by the manufacturer.

 

1100mhz+ is already very good for the 290x so I would not bother, as bios flashing has the potential to brick your card.

It can help.

Some GPU's with dual bios, for overclocking, sometimes the second bios will run better, but flashing the bios can yeild a better overclock potentially.

I think the dual BIOS stuff is to increase the clocks(on a lot of cards) and sometimes provides a fail-safe. It doesn't mean the GPU will overclock any better.

The other bios on most cards simply raise the power target maximum (on nvidia) and maybe default voltage. It won't change the silicon on your board and if you have already pushed until you are unstable it likely won't help you go much further.

In my experience, removing any king of boost state and running at a constant clock yielded me 30-40mhz more ( without touching the voltage ) on my 780. I have no idea if you can remove AMDs GPU boost equivalent with a custom bios though

It removes limits on the GPU which could yield better overclocks if you are at the limit of the stock bios now and it is still stable but it is risky though because you can potentially brick your GPU, damage it through too much overclock, void your warranty (If you cannot get it back to stock) and many more.

Flashing a hacked BIOS can help a lot with more voltage and better voltage curves. With that said AMD cards aren't really good OCers so I don't think you'd gain a lot of performance.

Honestly, even a few megahertz is fine. +40mhz already yields significant performance boosts.

I have my GTX 980 clocked in at 1530Mhz @ 1.28v I think stock voltage is around 1.21. So the flashed bios added 70mv. 

 

I hear the 290x/390x aren't great OCers and I haven't heard of many past 1150mhz, so it just sounds like you are at your limit.
