argh... I have this problem too but I am not as lucky as GargaZol. I am at 110mhz PCIE and it's still 1x for me... the graphics totally licks. sometimes my system crashes when I play games at 1x and reboots at 16x no problem. why is that happening? and how do I fix problem? and does the sata2 problem only happen when you are doing raid or it affects ide mode?
