I am using either nForce of nForce2 internal graphics, and I see

warnings like this in my X log file:

 

  Not using mode "1600x1200" (exceeds valid memory bandwidth usage)


Integrated graphics have stricter memory bandwidth limitations

that restrict the resolution and refresh rate of the modes you

request.  To work around this, you can reduce the maximum refresh

rate by lowering the upper value of the "VertRefresh" range in the

Monitor section of your X config file.  Though not recommended,

you can disable the memory bandwidth test with the "NoBandWidthTest"

X config file option.
