To obtain mode 6 you need to look into at least: a) your mobo chipset supports mode
6 - might be a driver upgrade that's needed, b) check the MS article
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q260233&LN=EN-US&SD=gn&FR=0
and c) that the cabling is short and high quality. Even so, I would not stretch
for the higher speed unless you *really* need it. Most folks will not. good luck.
