          Severity: normal
    Classification: Unclassified

          Reporter: p00hzone at gmail.com
          Hardware: Other
            Status: NEW
           Version: 7.7 (2011)
         Component: Driver/Radeon
           Product: xorg

I have two identical Motherboards Gigabyte Fm2A75-d3h.
First configuration:
[1] 2x 4gb DDR3-1333 + AMD a6-5400k
[2] 2x 4gb DDR-1600 + AMD a6-5400k Black Edition.

All systems ships with absolutely identical images with Arch Linux (Kernel
3.6.9).
X.Org X Server 1.13.2.
xf86-video-ati-7.1.0.

Every system has 3 attached monitors. I'm trying to launch 3 undependent seats.
Every APU have been tested at every motherboard with various memory modules. As
a result issues described above depends on APU only.

In addition to arch image all tests have been made at fresh installed Ubuntu
12.10.1 i386.

With [2] configuration system is working rather stable but with much artifacts
on desktop. OpenGL applications are flickering and tearing, but not freezes.

With [1] configuration no artefacts detected at all, but OpenGL applications
freezes after 5-10 seconds after launch. Only restart of x server can solve
this issue.
