I took out my old laptop from the store just to play around with it and see if it is usable anymore.
Overclocked the CPU to 2GHz and it seems to be running fine for a decade old piece of machinery.
What I'm wondering, however, is that when they sold this laptop to me, they claimed it has "1.6GHz dual-core processor." Looking at CPU-z info, it seems to be a different story. It's actually 700Mhz/core which they claimed to be "1.6GHz" at that time.
Can someone let me know about why this CPU is referred to be running at "1.6GHz" when it's essentially running two different cores at 700MHz which is not the same thing at all.
