so i just installed a new e7400 core 2 duo 2.8ghz so it says on the box. but in the bios and cpuid it is saying its running at 2.266ghz. windows also says this. in cpuid the core speed fluctuates from 1600 to 2.266, and the vcore is also fluctuating between 1.056, 1.072, 1.088, 1.120, 1,136 and 1.248 is the highest ive seen it. Is it normal for it to display like this?
