Hi,
I am just trying to edit my bios whit RBE 1.17.
I would like to make my card cooler whit the stock cooler - so I have to increase the fan speeds in my bios and to make the 2d speeds lower.

I have tried whit Rivatuner and Ati tray tools - but they are issuing problems whit different programs and games, so I prefer to do this in the bios.
Please can you help me whit the settings.
I know that I can change the 2d core and memory speeds to lower ones- but I would like to keep as much as possible the speed of my card by watching of .mkv files. Is there any lack of speed in 2d by decresing the core and memory speeds.
If there is some equal tread - it will be very helpful.
I have searched in the forum, but without success.
I am attaching the info from GPU-Z.

Thank you in advance!
Regards!

I am using 8.10 - bu there is only fixed speed.
Is not better automatic in steps, just lowered min speeds in the bios.

Benchmark Scores Meh.
8.10 has it built in, but it's built into CCC.

Either either one of two things (the latter of these I doubt, no offense heh). User error, or Sapphire didn't use an adjustable fan.

Run ATiTrayTools, it's what I use. Lets you set a bunch of temps and fan speeds.

Just use the look up table in RBE, if you have no idea on what values to use, download one of the bioses attached to my signature and copy the values.;)

I also flashed my bios a few months ago, but i have a weird problem now. The fans sometimes stop for 1 second, like they loose power. This happens alot, does anyone know what I can do to stop it?

here is a picture.

Yes but the CCC fan function is only for fixed fan speed, and I tried to use ATT in the past but that doesn't work so well for crossfire systems either.
