Hello all, I am having some troubles with overclocking my AMD Athlon II X3 425 cpu. I can get it to anything below 3.4GHz easily (right now it is at 3395.4MHz with 1.340V and I have been running prime95 for an hour or so without any problems) but as soon as it hits anything above 3.4GHz, it becomes very unstable. Even going from 3395.4MHz to just over 3400MHz and it cant run a prime95 test for more than a minute without one of the cores getting an error. I have tried increasing the voltage all the way up to 1.440V, but it just seems to be more unstable. The temperatures are fine, they never get above 46°C, and I am new to this, so I am not sure what could be causing the issue. I am fine with the CPU as it is now, but I just want to know why a few MHz more causes it to become so much more unstable. Also, is it normal for the Prime95 workers to finish their tests at different speeds?
