Sudden Voltage Spike might have damaged CPU

Last response: in Overclocking

February 7, 2011
Overclocked computer to 3.3Ghz Vcore at 1.428
Suddenly jumped to 1.98 volts
Cause Vcore is set to auto in bios
CPU may be a little damaged from voltage jump
Ram was at 1600Mhz running at 800mhz 9-9-9-24 at 1.5v 2T
Symptoms: PC is lagging and makes lagging noises while sound playback

Is this anything to be worried about? Should I return OEM settings? Ran Prime 95 a good 6 hours at current OCed with good results. I have ran system and found that increasing
Vcore to 1.428 v on cpu stabilizes this issue for my current OCed 3130Mhz/ bus 240 Mhz/ x13.0 .

if at the time of stability and successful test runs without error I think it safe safe though briefly rose to 1.98v (1.98 v read this from anywhere.?). The important thing is to keep temperatures below 65c, it will be very safe, clear your cpu is not damaged just maybe had to diminishing caused by overclocking. Other times do not vCore set to auto, you must seet manual and you have lots of other settings in bios as disabled c1e, coon n Quite, if c1e still active is the primary cause of jump VCore CPU.

Thanks for the quick reply. As you can see I'm just beginning to learn a little about Overclocking, I do have to give credit to the real enthusiasts.
I'm afraid I will just graze the surface of the topic and that I will never fully understand everything. There are some things such as mathematic formulas I must be missing. Of course, in order to establish a completely balanced Overclock a professional must take a measure of all the variables.
So many people are bomb-shelling there computers, because they are not getting the right information on the subject. Which is why this website will always have an astronomical amount of posts, from people who do not know what they are doing.
