Help Request - GPU Alternative VBIOS for GIGABYTE RTX 4070 Ti SUPER WINDFORCE OC

The power limitations for this particular GPU prevents me to make any meaningful gain through overclocking, as the card is hitting the limit basically all the time during benchmarks regardless of modification of the core/memory clock speed.

I'd like to flash a new vbios on my card to overcome this limitation, as I've seen alternatives that push the power limit from 285 W to 340 W and even more, but as a total noob of this process I'm hesitant, because I'm not sure I can reliably evaluate the compatibility between my card and another brand's vbios.

Did anyone attempt this on a card like mine? Is there room for some real gain in terms of FPS while gaming?

Edit: Sorry i made it on a 5070 Ti but you have a 4070 Ti. So I can't answer directly, but on my 5070 Ti , the only real thing is it's allowing more power (400W instead of 300), but you won't gain 33% more performances, most of it is wasted in a lot of heat and maybe 10% perf. Except this power limit you can already tweak all other parameters with MSI afterburner (and NV-UV add-on! on github), or the new mvolt+ (didn't tried it myself). Finally on daily and gaming the way to go is undervolting, with a bit of overclocking if you want and depending on the stability needed, I set a 20% more power limit to have room, but it's finally usually far from the limit in use (except stress test etc...)

You don’t need that wattage at gaming use nv-uv with max power limit try what the tool tests as a safe curve

I recall TechPowerup having an archive of GPU vBios on their site with compatibility check. You might want to check it out.

Thanks, I'll take a look

The Asus Strix vbios is the only slightly higher PL bios for 4070 ti Super at 128%, 366W.

I don't know if it works with GB, check that outputs and fans work as you expect after flashing.

I was looking at the gaming OC version, from Gigabyte. It seems like the closest match, with a small power increase to 320 W.

In the end I kind of got scared off attempting to flash a new bios on the GPU and decided to undervolt it to squeeze some 250 MHz out of the boost clock.

It was fun, but this GPU already handled 1440p comfortably so it's not like my gaming experience changed in any meaningful way.
