Hi, I'm currently using Riva Tuner (RT) in order to tweak the fan profile of the card. As always better practice would be to flash them into the card using RBE. Riva tuner gives total of 8 parameters to tweak. As for RBE some of them are missing, here is the crossreference for RT and RBE I was able to figure out. Riva Tuner --- RBE 1. Tmin --- Tmin 2. Tmax --- Tmax 3. Trange --- Trange 4. DC min --- DC min (box) 5. DC max -- Graph ! 6. Toperating --- Target Temperature 7. T low limit --- ? 8. T high limit --- ? The last 3 parameters are for the dynamic control (aka dynamic Tmin control). I'm having trouble finding the last 2 par. in RBE ! Maybe T low limit is set to Tmin and T high limit is set to Tmax ? (Can someone confirm this) Thanks.
