Hi all. Sorry for my bad english, but i will trying my best to explain my problem to you guys. My comp is very unstable with the Cpu ratio at 11x or default, the other settings at default too and Prime95 shows an error after 40sec of torturing test. But if i set it to 9.5x, HT 4x, rams at 231mhz timing at 2.5-3-3-6 my system is become very stable, 0 error after 1h of torturing. I think that my 3500+ is malfunctioning.
