I recently overclocked my amd x2 6000 from 3.00 to 3.2 and bump the volt from 1.475 to 1.525 V but what i noticed that system is stable but whenver i acces the motherboard PANEL from NVIDIA CONTOL PANEL my system lights SHUTOFFF for 3 sec... thats scary eveything goes like it running outta power or sumthin buh i havent seen instability yet... my specs are

MOBO Nforce 590
PSU Ultra 600 W
Corsair 6 GB 800 MHZ

try putting the volts back to stock, a small OC like that shouldnt need a voltage boost let a lone that much.

You mention it seems stable....get a program called prime95 and do the stress test on it see if it can do it for at least half an hour without giving an error....assuming you have not already done this.....

yupp thats done .... its stable but i have seen sometime PC lockups randomlyy

Seems like a hell of alot of volts for a system running 24/7...I have not clocked an AMD CPU since my San Diego core back in the day....but thats seems excessive al the same.

Yeah I have to agree with what's been said by the people above, that small of an overclock shouldn't need a voltage boost. Make sure you set fixed voltage instead of auto, when you OC though. And if it locks up, then it's something else.

wht sumthin else ?

i thnik am sure i got lockup coz of overclockin but like why ? my TEMPS are not even going far than 55 or nything then why do i get lockup...

If you're going to ramp up just 200MHz, everything can still be left on auto.
Intel Quads, mine for example can be ramped from 2.40GHz to 3.0GHz and everything
still left on auto. Not too sure how good AMD are for overclocking these days, but I'm
positively certain they can handle a meagre 200MHz jump with auto settings.

As for your Volt jump - holy s**t! That's a huge unnecessary tweak for such a small
OC as has been mentioned by other members on here. I would use that voltage
for OC'ing 50% of the CPU. Careful in future with your volts tho.

Yeah messing with the volts that much can physically damage the cpu internally, even though you may not think it's broken. I hope you didnt run it for long with those volts because that's just too much.
