Hello there. i am trying to mild Overclock my System ..But i have wired Issue. i am not sure if this is normal. or any Bug So im asking...

Now the problem

I did not touch anything other then made Core Performance Boost" disable. then pressed F10 then Yes. Now i see the system turn Completely Off and after 1-3 sec turns back on.

same thing happens if i restart my system from Windows its goes to Shutdown mode meaning no light on my Cabinet then after few sec(2-3sec) Its starts...

But if i enable "Core Performance Boost" Everything is fine. no Cold shutdown. System restarts normally as it should...

So my Q is Is this Normal for this mobo to behave in such manner after Core Performance Boost" is disabled ?

If anyone using this board could help me .i would be really glad.

My mobo came with BIOS ver. FB even i flashed FCb BIOS but Same issue
 
Solution
hmm actually now that I think about it mine does the same thing, I wouldn't worry about it . when you turned the turbo off did you raise ti to the turbo frequency and check your voltage as well?


Yes . u mean the same thing happens to you ? like when restarting from windows it shuts down for few sec and starts ?
 


well i see my Cabinet power Led turns off all fans off. then after 3 sec or so turns on by itself. rather then restarting normally. this only happens when u disable Core Performance Boost/ AMD Turbo Off/Disable
 
actually i wanted to disable all safety option like turbo boost,wise scholar n quite , APM etc. and increased the CPU multiplier to 19 from default 17.5 .. didnt changed anything in voltage. they were in auto mode...

so after i save and exit the bios system shuts down. and after 3 sec boot up.

So i tried to figure what is causing this cold shutdown. and found it hpns whn disabling Core Performance Boost

Just wanted to know if this behavior is normal ?
