x58 i7 nvidia gtx 260 questions.

[cfreakyo]

hey guys,

 

i've just installed iatkos v7 osx and have my i7 setup working but not without some minor issues. i'm still using 10.5.7 at the moment and when i look at "about this mac" it's displaying my memory as ddr2 when it should be ddr3. i'm not 100% sure that the bus speed displayed is right, it shows 533MHz for my i7 920 cpu on my gigabyte x58 ud4p. my last issue so far is that my graphics card isn't quartz supported, or so it says. it's displaying the right chipset and so on but quartz isn't working. here's what it shows:
