What's Dangerous?

Hi guys, I'm a newbie here, I'd like to overclock my (cpu AMD FX-8150 Zambezi) so what I did was push the "O.C." button on my motherboard (Asus Crosshair Formula V) and then went into the bios and selected a pre-set overclock thing i believe... I also enabled "boost" whatever that means... basically i went from getting 3.6-3.9GHz to getting 3.9-4.3GHz I'm not really sure why there's fluctuation...? also my temps rose by roughly 15 degrees C. I'm running the stock heatsink, so that's why I'm really nervous about this whole situation, obviously i'm not reaching for the 5+GHz yet, but once I get an H100i or something I might try...In the attached pic I'm running Folding @ Home on full... just as a reference point... my temps seem to be holding steady at 58 degrees... If you don't mind, I'd like some tips for overclocking as well as input as to what a dangerous cpu temp is.

Just keep you hands off the voltage since you are using the stock cooler. And don't leave the VCore on auto since that will automatically overvoltage the CPU. You can set the default voltage manually and try to see how far you can overclock.

Are you serious? OCing with stock cooler? please get a real cooler first

 

chill bro, i've been quite impressed with the stock cooler (except for the noise level)... obviously it's running below 75 degrees... and I'm not really pushing the limits of an 8 core (yet(like i said i would be getting one soon))... whats the big deal?

I didn't touch the voltage, just using the preset thing. what would you suggest as a good voltage? also, is there a way to keep the fluctuation down? keeps bouncing from 3.9-4.3

The 8150's stock voltage is 1.2625v, so you I recommend setting it to 1.26v. Just make sure your temps are below 70C. The Bulldozer CPUs aren't that good at handeling heat. You should also try and look into overclocking the northbridge and the hypertransport bus, since overclocking those insted of the multiplier ususally grants better results

alright, you lost me... northbridge? hypertransport bus? but i'll go set the voltage :P brb

That is more advanced stuff, but they are an essential part of overclocking AMD CPUs. You will not be able to overclock to the full potential without thouching the northbridge and the hypertransport bus. You will still be able to overclock though

Alright, I changed the voltage to 1.26 and got a blue screen.... so I changed them back to "Auto"...??

I wish there was a way to print screen the bios screen lol but i have so many voltage options that i could have changed...? also i found what i think is the north bridge.... I might have to search youtube for a tutorial... :/

Probably a good idea. I'm not an expert on AMD overclocking, and a lot of people are better at it than I am

the stock voltage for your chip is 1.4v not 1.265v otherwise it would use a lot less power.  ;)  if you set it to 1.4-1.425 then you should be able to overclock it to 4-4.2ghz but i wouldn't go any higher unless you have replaced the stock cooler, but make sure the temps are no more than 65c ish under full load

 

The 8150's stock voltage is 1.2625v, so you I recommend setting it to 1.26v. 

i wish  :(

My sources were wrong? This magic 8 Ball is a rip off.

But seriously thanks for correcting my mistake. I got it confused with another CPU.
