Hi, I'm one of the suckers that bought an AMD FX-4100. It's not bad, compared to my E8400, it's about equal really. I havea question about the speed of one of the cores. When I monitor the frequency of the cores individually, Core #0 is constantly droping from 3.7 ghz to 1.4 and the multiplier at the same time drops from x18 to x7. The other 3 cores hold steady at 3.7 ghz. Is this normal or do I have a faulty cpu? I'd like to know for sure while I still have time to get a replacement. Thanks,
