Overclocking with UT X48 on 45nm Quad.

[ahhuat]

hi guys , i'm new here.
however i have some issues with my overclocking.
i can't seemed to get it prime stable at 425 FSB , can't even boot from bios at 450 FSB.
tried increasing vcore, NB , VTT voltages as well
the fsb:dram ratio also giving me problems , as in whatever i choose are not stable at all.

my specs:

X3350
UT X48-T2R
Ballistix 2x2GB

really need help badly , i have no idea on what to do already. thank you so much.

Try that and see if it helps. I suspect your RAM was too high.

prime still fail within secs

Need some extra Vcore then most likely.
