Could cause voltage weirdness if your VRMs aren't behaving appropriately. Lower your VRM Frequency to 350, and try changing phase control to default.

it didn't work...same instant bsod frown.gif

Bah I wish I could offer some suggestions but I have no personal experience with i7's and their boards... frown.gif

1.344 is not a BAD place to be, but here are a couple things you can look into:

1)Do you have XMP enabled? If not, try loading the default profile in.
2)What is your PLL voltage at? I think mine had to be set at 1.7 (or maybe it was 1.8) to be stable at 45x @ 1.32
3)Make sure the TPU switch is not enabled on the motherboard itself and that the BCLK is at 100

1) Yes, is enabled.
2) Pll was 1,75. I'm trying 1,71 right now
3) TPU switch? i guess it's off...is something i have to set in the bios?


Anyway, i figured out something both interesting and weird.

I tried lowering the VCCIO. This made my system much more stable.

For example, @ 4,3ghz 1,27v with 1,08vccio ---> Bsod 124 in 1 or 2min
1,05 vccio---> bsod in 10 minutes
1,03 --->bsod in 20 minutes
1,012 ---> bsod after 2hr 20 minutes

Any thoughts!? Lowering it more made my system unstable again. I guess my sweetspot is 1,012...but it doesn't make any sense.
