ATI 5850 Monitor BIOS Fix

post #1 of 29
Thread Starter 
Hello I was wondering what value I change to fix the dual monitor flicker issue. I have come across a fix to the issue and I would like to make it permanent by flashing it into the BIOS. I would like to have the RAM clock set to 450mhz in 2D mode. Here is what I have to work with:

I appreciate anyone's input and help. Thank you.
P.S. Also what does it mean when I click and hold on the number one under power-play states and it highlights two clock info fields with different colors?

If you have 60hz refresh rate monitor, your video card should not go beyond that rate.

I don't quite understand what your getting at. I have 2 monitors and whenever it is set at the default 2d clocks of core:157mhz and RAM: 300mhz I get gray bars running across the secondary monitor. I am trying to create a permanent fix by using my temporary fix as a template. My temp fix is using AMD GPU Clock Tool.

I thought problem was flicker issue. That may be something to do with monitor's refresh rates. Make sure both of your monitor shares same refresh rate and also check your CCC for refresh rate.

No it isn't the refresh rate it is the 2d clocks in the BIOS. I need to know what value to change to 450 in order to solve the issue. I have a temporary fix using the AMD GPU Tool. I changed the clock to 450 mhz in there and it works perfectly I just need to know where to put it in the ATI RBE tool.

Not really sure, just back up the og bios and test your settings.
