Hey, so, yeah like the subject says, I would like to OC my CPU AMD Phenom || x6 1090T to like 4Ghz atleast, but it keeps bluescreening all the time if I OC it over 3,7Ghz :S ... And the funny thing here is that, I got this CPU from my friend and he had it OCd to 4.2Ghz , but I cant get it to 3.8Ghz...
Your motherboard isn't too hot, and x6 thuban's are locked processors so they can be a little tricky to overclock, try dropping your ram down to 1333 before overclocking as well that can help, and uhhh, do you have a CPU cooler or are you on stock?
I think the biggest problem OCing is the power Phase on that MOBO, you may be pushing it with voltage that high, I recently upgraded my board and solved this same problem.
i have a 1100T BE and let me tell you getting it to even boot to windows at 4.3 ghz required massive voltage getting boot to windows at 4 ghz required around 4.89 volts with upping multi and messing with fsb. i will say this unless you have one hell of an upper end mobo dont push your cpu to 4 ghz you will more than likely blow a capacitor or even fry your cpu. i cant even stress this enough phenom II is hard as hell to get stable at high voltages with out massive cooling and rock solid mobo and psu. i would not recommend a locked phenom II going past 3.9 ghz the stress on components is not worth the risk.
