I was doing good, had a pretty stable 3.8ghz but after about 4 hours of multi task it finally gave me a 124 BSOD. so I started messing with it. and increased my VTT to .375, and figure I mess with some of other settings trying to get it to 4.2ghz. I know its bad to mess with stuff when you dont have a stable core. but I figured I would try to get it some what stable at 4.2, but I feel like I am setting some stuff to high and other stuff not high enough. And for what ever reason I cant get it to do the 4.3 at the same vcore I have sig. anyways I took some Screen shots of my Bios. the settings in it arent where I am right now. just mess around. Please take a look and suggest what might need to go up and what might need to go down,
Ok some changes I did: Disabled the intel speedstep. I increased the CPU pll to 1.89 (there is no option for 1.88) and and my Vcore is 1.3875 and my CPU Vtt is +375mV.
and my CPU speed is at 3.9. It will boot up but when it get to load win7 it shut down and restart and I see no BSOD. so, I am not sure what to change.
Ok, I am getting a little bit confused. what is the difference in my CPU VTT and my QPI PLL? when I am reading on i need to set my qpi/uncore(VTT) at 1.35, which are they talking about? and what is the other for?
ok I think I i got it, i am to mess with the QPI PLL and leave the VTT alone. I am running a Prime95. and I am also running Coretemp, question on that is the temp is safe as long as its under 70c right?
Yeah I am going to change that next. i was wanting to see what I had my memory set at on here in my sig because that is stable.
Will disable Execute bit. And I went back in have my turbo on, and set at 20(21).
CPU Multi?
and what are setting I need to look at for my PLL's?
After I get done with this 1 hour stress test I go back in change some of what you say and take new Screeen shots and post them.
Turboboost wont engage unless your cpu multiplier is set to auto.
You can see evidence of that when running prime on one core only. So one thread only.
When TB is enabled and cpu multiplier set to auto, running prime on one thread, you will see the multiplier go up to x24 in cpu-z
When the multiplier isn't set to auto, but to 20 like you did, you won't see that x24 multiplier when priming on one core.
Although I have a 950, it might help get you close, no guarantees, though. Also, my memory settings probably will not work for you, that is something you will need to figure out.

Ok I have a question, can you pump to much Vcore for a OC and make it unstable. the reason I am asking is that I keep getting a BSOD that waw 101 0x1e and even 124, so I would keep bumping up my Vcore and QPI. finally I deside to it was getting really high for my OC. and I deside to decrease it alittle from the setting I had it before bumping it. And now its seem to be stable.
And I am back at 4.33, and YES i am saving my Profiles as I make changes. and Saving Profile 1 for my Dom Set up. and 2 for a OC for something I might want to Bench at(special). I did learn my leason.

From own experience (which actually isn't really much
), too high QPI/IMC will cause unstability.
At 4.2ghz I am not stable with vcore 1.36V and QPI 1.27V, but I am with 1.36V and 1.17V QPI. Strange but true...
