I had my 4400 running at 2.6ghz stable. Once I bumped it up a few more mhz I got errors in prime 95, I started taking it down but it was too late. Windows then crashed. My ram is pc-4000 and I only had it running around 200 some mhz, so that wasnt the problem. I had 2.8 volts in it. I'm thinking it was a voltage problem, not having enough in the cpu. I had it at 1.36v. The load temps however were only around 44*c. I'm also possibly thinking it could have been a pwmic heat issue (thats been running load around 53*c.). Any advice? Should I call it good as close as I can get the cpu on these settings? what could be the road block I hit, and how should I fix it. I'm looking into watercooling as I type this, which would always help. This is on stock cooling right now btw.
