40 minutes prime stable

i noticed a few things... on idle, my temps are from core0 to core3: 42 38 42 38... you'll notice that theres one less wire behind the monitor, i was trying to find out why im getting 6 degrees difference between the cores and i tried messing with the tensions of the springs on my waterblock, then one of the springs jumped out and i had to push my desk around to find it again etc etc etc
however, on prime95 load, its like 51 47 51 51 or 51 50 49 51 ... the 2nd or 3rd core seems to be running some kind of windows vista 'idle' task which keeps them from being fully loaded ... also the 2nd core seems to be the coolest running of the cores... when it happens to be the 2nd core which is running the 'idle' task (i.e. 3rd core fully loaded), it crashed alot more often, but when it is the 3rd core with the idle task (i.e. 2nd core fully loaded), that was when i got 40 minutes out of prime... but it is also the 2nd core which crashes the most often
i tried adjusting the gtl's ... if for example, i change the core1/core2 gtl from 99 to 98 or 100, the second core would error out within 3 or 4 minutes, but im not totally sure yet because i only did that once... but at least im actually getting prime errors, not hard system locks anymore, turns out that i had to up the vtt, now im testing at 1.36v, in the bios this makes it read 1.38v, when i try the low 1.3's the system would hang totally after 3 or 4 minutes... and im not sure if this is happening or not but if i increase the vcore, while keeping the vtt the same, my top temperature seemed to drop from 56 degrees to 53 degrees, its probably that i need to spend more time looking at the temperature readouts...
but anyway, since i know that my board can do 442mhz fsb, im trying to keep it at that speed, and make my q9450 hit the 3.53ghz that my old q6600 did during the winter... my method is to start at a certain voltage, then go up on the gtl one by one to look for the setting which would keep both pairs of the 1st and 4th core , and the 2nd and 3rd core stable for the longest... if the 1st or the 4th worker thread in prime95 crashes, i mess with the cpu0/cpu3 gtl setting, if the 2nd or the 3rd worker thread in prime95 crashes, i mess with the cpu1/cpu2 gtl setting... if it still crashes after a few minutes, i up the vtt by a notch or two and start trying higher gtl numbers
::edit:: tried 1.36v vtt and all core gtl settings from 95 to 101 give errors within minutes... maybe im pushing it too high or something, should i try to up the vcore instead
