Flash unlocked 3A bios onto LN2 chip using nvflash thumb.gif


Does anyone know the location (offset/columns when using hex editor) of the max boost clock (not normal boost clock displayed in GPU-Z this doesn't really do much) in the kepler BIOS?

Thanks

EDIT

Now works, flashed to 3A bios, that tutorial missed some essential thing, you need to rename the 3A bios file, then to flash it....you should update...

Final version custom air bios. I have 2 higher clock water bioses too for when my block gets here biggrin.gif

100% Power target increased to 250w (power slider can stay on 100% now still have 9% TDP to spare)
Max board power still 300w
Base clock: 1202
Boost clock: 1267
Max boost clock: 1280
Mem freq: 1856 (3712 or 7424 Effective)
vgpu: 1,2125v (1,24v real measured with DMM)

testing with kombustor to verify max boost and TDP

I'm having problems changing the Voltage on my card. When i increase the voltage in afterburner, the voltage does not change. I'm using the 80.04.28.00.3A bios, and my voltage maxes out at 1.212, and all overclocks past 1250Mhz crash.

Did you flash to the 3A BIOS that you have or did it come with the card?

And are you using Afterburner 2.2.3?

Dang fed ex is screwing me. GIMME MY 680L !!
post #4797 of 7827
with all the support for these cards im surprised no one has modified afterburner to allow higher voltage control. like a home brew afterburner extreme

Hey guys,

I read somewhere that reducing my power limit from 300 could give me a higher OC stability, anyone shed some light?

I had someone suggest I try that, saying the power limit was too high if it's at 300. But I didn't see any benefit from lowering it, and in fact it did make my overclock less stable and I could not get as high.
