it doesn't seem to load all the info from my card.... is the version publicly available compatible?
With an nVidia 5xx series card, not the Gigabyte 560Ti, I find that with nVidia Bios Editor (NibiTor) 6.02 the Clockrates and Voltages tabs are greyed out. Advanced Info apparently reports the correct details. Timings are greyed out. On the Temperatures tab the minimum and maximum fan speeds are editable and nothing else. They are shown as PWM duty cycle %. So it looks to me that if you are seeing the figure '40' in the min fanspeed box you should be able to change that to say '30'. There is a Boot Settings tab with everything apparently editable but I would be inclined to leave that alone. Otherwise I suspect I am seeing what you are seeing.
NiBiTor includes the facility to save the existing BIOS (File-->Save BIOS) and it would obviously be wise to do this before attempting any changes. In addition, Gigabyte have a downloadable @BIOS utility for their GTX 560 Ti cards. This Gigabyte utility, as I understand it, will also enable you to save the existing BIOS, and load a BIOS file again if required.
