I've just bought an AMD Phenom II X2 550, and successfully unlocked another core, so I have cores 0,1,3 working just fine without editing anything.
When I activate the 4th core though, when I have 0,1,2,3 all working, the windows loads, but just minutes after I log in my account it restarts without warning, also before it restarts the whole system is slow, some programs refuse to open "Kaspersky + Firefox", and the login music has some noise in it.
I've read somewhere that there's a chance to stabilize the 4 cores if I increased the Vcore voltage, and also by increasing the north bridge voltage I think, and finally by playing around with the cores calibration.
So I increased the Vcore voltage from 1.35 to 1.38, didn't work. I didn't try to increase the north bridge voltage because I'm not sure I understood that stabilizing topic well. And finally I went on the calibration from -2% to -4% etc, till -8%.
At -4% the music noise was less, barely none, the system wasn't much better though, just a little.
Anyway I don't know anything about overclocking so I'm really afraid of doing anything dangerous, so if there's something I can do to stabilize the system that would be great help, I just wanna be sure before increasing some voltage or fry my pc xD
