This is my first overclock and I need some help with refining my settings for my system. I plan to use this rig for mostly gaming, and editing.
 
Specs:
Q9450@3360mhz
TRUE with 1900rpm s-flex fan
Asus rampage x38
2x2gb G.skill 1066 pc8500cl5
Corsair 750 psu
Vista ultimate 64bit
 
So far I've been running prime95 smallFFT for two hours and I plan to leave it on for 12 hours and see what happens (It has not crashed yet). I also have this small annoyance that will be awkward to explain but I really want it fixed. When I move my mouse around on the desktop the cursor skips and the system freezes for a split second. This happens randomly every 10 seconds or so very predictably. I don't know where to even begin to correct that so any info would be great. My goal was to reach 3.4-3.5ghz but theres too many BMOS right after  Vista gets to the desktop...
 
 
These are my current BIOS settings:

This is what my CoreTemp shows under prime95 load right now:
 
Tj max: 105C
Core #0: spikes between 63-70C
Core #1: spikes between 61-65
Core #2: spikes between 60-65
Core #3: 65C
 
I think on idle they were in their mid 40's. Let me know if these temps are OKAY. Intel site lists the max thermal for Q9450 as 71.4C so I would assume I'm fine?
 
 
I want to refine these settings and possibly reach the 3.4~ ish area so any help would be appreciated
THANKS
