Could changing bus speed result in system unstability?

[Drastik]

I just went into Catalyst control center and my bus speed is a x1, so i seen theres a option called 'SMARTGART' which allows you to change the bus speed in windows, but it says that the program has 'determind the optimal settings to ensure system stability', and that if i change the bus speed it could result in system unstability.....

Is this the case since my previous gfx card was at x4 and it had no problems.
