little bit more info on your volts+divider used would be great.
ok from other thread i see you used 1,35 qpi and 1,65 ram.
best is you try how high you can go with this volts and cl9.
so start at example 1800 cl9 with 2:10 divider and 19 multi on cpu.
then work your way up in 10mhz steps testing with hyperpi and if its unstable push little bit qpi and see if it helps.
you got asus mobo with very good windows tool turboV-so you dont have to reboot every time.
from my experience with trident - they need little bit more qpi volt up to 1,45.
