Does it work if you plug the graphics card directly to the PCIe slot?

The root port (1c.4) says this:

      DevCap2: Completion Timeout: Range ABC, TimeoutDis+, LTR+, OBFF Not 
Supported ARIFwd+
           AtomicOpsCap: Routing- 32bit- 64bit- 128bitCAS-

Not knowing much about AtomicOps but to me this looks like the root port
does not support the feature.
