I was running 146 FSB off of cpucool for a few days and it was fine. I ran some benchmarks and stuff as well as casual use for at least 4 days or so and I had no troubles whatsoever. Then I decided to do it through BIOS since, if i remember correctly, it was more stable. I run it at 146FSB through bios and then a lot of my programs started to lock up... I was just wondering if this happened to anyone else. Should I continue to OC through software or just run 142FSB through BIOS? Also, anyone know of a free software that can raise FSB on ECS K7S5A? Thanks~
