Soz, replied to something a page back.

Stu, pushing temps to around 80 for a 24/7 rig is quite dangerous. Try fiddling around with your multiplier and lower the Vcore to 1.41 again. Do not go above 1.46v, you're risking frying your CPU now.

My vtt is weird. I'm assuming this is talking about the CPU VTT? It is listed in my BIOS with mVs. I'm still trying to work out exactly what these are and how they play into the equation.

I think that my CPU PLL is on auto, but when my system crashes next, I will put it at 1.85. I had it there before, but then I took it off when it seemed unnecessary moving from 4.0 to 4.1.

I'm definitely not going to exceed 1.45V. I'm trying to keep it as low as possible, but maintaining stability. Thanks for the stern warning though!

Turn off the auto reboot and you can find it in your even log to.

If you dont know, you can turn off auto reboot by restarting your computer and pressing f8 and when the menu comes up, select the "disable auto restart...." option. Then the next time your computer crashes, it will hang on the blue screen until you manually restart it.

Tried this, but it didn't work. :\\

However, I did read the blue screen error and it was one I had not seen before. Was 100000...9. Weird.

I'm going to go to bed, but this was my final IBT log with the CPU PLL raised to 1.85:

Hmm well in the morning try bumping it to around 1.88 cpu pll and 1.34 VTT. That's what im running and it works fine. Also whats your IOH voltage? IOH is your north bridge. Mine need's like 1.22V.

I can probably take a pic of my BIOS for you and you can somewhat go off my voltages and figure out what you need to do. Let me know if that would be helpful and i'll do it for ya

I have not yet messed with the northbridge voltages... hmm...

How do it come into play with the rest? I don't recall reading about changing it at all. Sorry for another newb question!

Well do you have all your voltages set to auto in BIOS? The first thing i did was manually set all my voltages when trying to OC.

Adding a little voltage to the NB helps but i forget why again I just know that it helps as long as you don't go too high

Have you tried CPU PLL at 1.88?
