Are you talking about the site that purportedly let you check the "original" Mhz of the CPU?
That was complete BS, and a lot of people fell for it. Those numbers were just date/lot production codes. No CPU maker would be stupid enough to print both the binned speed and the marketed speed, both directly on the outside of the CPU.
I'm glad to hear that the site is gone, it was doing nothing but spreading misinformation.
