How to safely ramp up Vcore in FX-6300?

I'm having X101 BSODs (recurrent) and some people say that slightly increasing the vcore can greatly increase stability. How do I do that in my BIOS, and to what amount should I increase it to if I'm only looking for stability and not really overclocking for performance?


Thanks.

EDIT: if you can, please give details on what changes I should make to the general AMD settings for the alteration to take effect. For example, should I disable AMD's "Cool N' Quiet"? (my money is on 'yes').
 
In your bios.
Go to the advanced page.
From there go to the Jumper free configuration page.
Under CPU Overvoltage section select it by using the "enter" key
Use the "+" or "-" keys to change it from AUTO to 1 step higher than your CPU default voltage.
Every chip is slightly different so I can not say what your default voltage is.
Then press F10 to save and exit. When the window pops up make sure yes is highlighted and press enter.

test for stability.
If you get errors still, raise it one more step.
Save and exit again.
Test for stability.
Repeat as necessary until you reach 1.45v for 24 hour heavy usage or 1.55v for couple hours a day usage.
Once you reach 1.4 volts keep an eye on temperatures. If you have a stock cooler try not to exceed 1.4v.
 
What board is it ??
What's your current vcore shown in overdrive & cpu-z while under load ???

Its somewhat dangerous to recommend upping your v core without knowing the above.

Its also very very unlikely you need to up it on stock clocks - every fx CPU I've ever used (which is a lot) is fairly heavily overvolted by default if anything.

Changing your llc settings in bios may gain stability or the problem likely lies elsewhere.

& no leave cool & quiet enabled - it only comes into effect at idle loads anyway.
 


Right now it's idling and it is 0.936 V, per CPU-Z (Overdrive is giving me nothing on the CPU, only GPU). If I stress it on CPU-Z, it gets to about 1.296 V. My board is a cheap ASUS one, whose name I don't recall, but it's on the part list that's on my signature. What are llc settings, by the way?

 
Line Load Calibration.
Basically it increases input voltage to the CPU when the voltage drops(V-Droop) when stressed.
When a processor is loaded the first parts of the chip will consume more of the power so that other parts of the chip receive less. Lower voltage.
Also heat plays a factor. The hotter the chip the more voltage that is turned to heat, causing a hotter chip and more voltage getting turned into heat.
Which causes voltage drops inside the CPU. the hotter the copper interconnects get the less voltage they deliver to the chip.
 


exactly what this guy says, on boards like yours also the voltage regulation through the vrm's can be inefficient under load,requiring more voltage to gain stability ,upping the llc a notch has essentially the same affect as upping the voltage slightly but will not affect idle temps or voltages.
Its safer than playing around with voltages yourself in all honesty.

 


Sounds very reasonable, and the explanation makes sense, considering that the BSOD's message says "A clock interrupt was not received on a secondary processor in the allocated time interval". How do I go about changing this particular setting, and more importantly, to what should I set it? I don't see any relevant data on CPU-Z at the moment.

Damn these cheap motherboards BTW.
