Fermi Bios editor unlocks voltage limits

[Tempered81]

Whats up GTX400 guys. I don't have one myself, but I just came across this program a guy on XS is using to mod people's bioses. He's posting up the newest bioses with voltage limits completely unlocked up to like ~ 1.213v. (Something afterburner doesn't offer) 1ghz thermi anyone? 🙂

If you wanna use it, you have to flash your own bios - so heads up: know what you're doing, and know the risks involved. Anyway, if you're an extreme gpu overclocker it will come in handy.

Wow he got the gtx 480 to 950 core! 30% overclock. Should be enough to take out a 5970.

Yeah he's at 960mhz in Heaven & Vantage. At 850 1.075v, he's pulling an extra 105 watts on the card!!!
~420 watt gtx480. Can't imagine 960mhz 1.21v. Probably spiking over 500 watts for the card alone.

Idle time I consume 212W, which are not optimized, as the CPU for example, always running at full voltage. With Optimized values above system takes about 180W to go with 45 - 50W on the calculations of the GTX 480.
GTX 480 @ default 0.950 v - 426 - 436W
GTX 480 @ default 0.963 v - 433 - 441W
GTX 480 @ default 0.975 v - 436 - 445W
GTX 480 @ default 0.988 v - 440 - 448W
GTX 480 @ default 1.000 v - 446 - 454W
GTX 480 @ default 1.013 v - 451 - 466W
Default GTX 480 @ 1.025 v - 458 - 468W
GTX 480 @ default 1.038 v - 466 - 473W
GTX 480 @ default 1.050 v - 473 - 482W
GTX 480 @ default 1.063 v - 479 - 488W
GTX 480 @ default 1.075 v - 488 - 498W
GTX 480 @ 1.075 v - 700/1400/1850MHz - 488 - 498W
GTX 480 @ 1.075 v - 750/1500/1900MHz - 497 - 506W
GTX 480 @ 1.075 v - 800/1600/1900MHz - 505 - 514W
GTX 480 @ 1.075 v - 850/1700/1900MHz - 510 - 520W

Vantage @ 1.200 v - 960/1920/1900Mhz - ???????????

And the 30% OC gave him a direct 30% boost in framerates in Crysis Warhead too. 34.4 -> 44.42

And 'brown out' his neighborhood while he's at it.

very impressive. it is no secret fermi scales well with clocks, but that is a great feat. he was using water cooling to get there, just as I thought.
