Hi guys, coming out of lurker mode for this. I'm doing some overclocking for a friend and can't get this Q9450 stable at or past 3.8.

Specs:
-Q9450
-Rampage Formula (0601 bios, pencil vMod, active NB cooling[doesn't go above 35c])
-4GB G.Skill 1066
-Seasonic 550W PSU

Ran perfectly at 450FSB with just a small vCore bump and everything else auto.
However it doesn't like 480+ FSB. At 480 I can get it to post and get into windows, but any load causes a bluescreen. Increasing the CPU PLL or FSB termination causes it to not load windows at all, or not even post. I have the CPU multi turned down to 6 while I try to get these higher FSBs to work. The ram is only at 960/2.1v so that shouldn't be it. All CPU features are disabled.

Here are the settings that have allowed me to at least run orthos for about 30 seconds before crashing.

Code:
Ai Tuner: manual
CPU Ratio: 6
FSB Strap: 400
FSB Freq: 480
DRAM Freq: 960
CPU vCore: 1.356
CPU PLL: auto (worse when I increase)
NB Voltage: 1.51
DRAM Voltage: 2.1
FSB Termination: auto (worse when I increase)
LLC disabled (pencil vmod done)
Any advice would be greatly appreciated!
