--- Comment #4 from Alex Deucher agd5f@yahoo.com --- pcie 2 mode has been enabled by default for a while now. Also, most recent motherboards bring up the card in pcie 2 mode by default. HD5450 cards tend to have slower ddr3 vram rather than the faster gddr5 as higher end cards do. Is this still an issue with a more recent kernel and mesa?
