First let me tell you what kind of pc i have and we will go from there. Asus M2N-SLI DELUXE AMD X2 3800 Windsor 2 gig GSkill pc 6400 @ 4-4-3-5 2t stock Ati Sapphire x1800xt Zalman CNPS9500 AM2 cooler HYPER 580 watt modular p/w Moving on, this chip will do 2.6Ghrz stock volts without a problem. Anything more it results into a reboot everytime. Though i have hit 2.7 Ghrz and 2.75 Ghrz for a little time but result in app locking up and windows crashing also. So do i need to try a burn in program? If so which one and how do i go about this issue. I really feel i should be able to get more out this cpu but could be wrong though. So any tips or suggestions to try would be helpful at this point. Good Day.
