I was setting up a second monitor. After setting it up and
extending the monitor I noticed that the second monitor has a really
bad flicker. The flicker is generally horizontal and will not go away
with resolution/refresh rate/color depth changes. Moving a window
around the #1 and #2 desktop makes the flicker worse. the flicker is
generally present on whatever monitor is set up as the secondary. The
primary monitor will remain flicker free. or if it does flicker it is
very minimal.
I did a search and found others having the same issue. Others have
discovered that if you turn off , or rather disable "ATI overdrive" in
CCC the flicker goes away. which I tried. and in fact it does.
The problem though, Is that even though the "Enable manual fan
control" is ticked. once you disable the ATI overdrive. The fan speed
for both cards. will be reduced to what I assume is default speed of
21%. the slider will move and the values will change. but the apply
setting does not function.
This is creating a problem with me having the ability to run Dual monitors.
I can disable ATI overdrive to run dual monitors and have no
flicker, but it results in my cards getting extremely hot. due to the
fact that the fan speed will not run past 21%.
If I enable ATI overdrive I regain control of the fans.
This was happening In 9.10 and is also present In 9.11.
I haven't had any responce from ATI on the issue .
My question is . are there any third party utilities that will enable me to better control the fans other that the CCC provided by ATI. that work well. such as EVGAs pressision
