The biggest overclocking story of all time was when people discovered that (many/most?) 300Mhz Celerons where intentionally mislabeled 450Mhz ones, because apparently the yields where such that they couldn't not make mostly 450Mhz ones.
- rasz 6y agoThose werent miss-labeled, as there were never 450MHz Celerons. This overclockability was due to excellent 0.25um lithography process Intel was wielding at the time. Every Intel CPU had same MHz ceiling, even older laptop 200MHz Pentium 1 MMX Tillamook CPUs overclocked to over 400MHz https://www.youtube.com/watch?v=fqB4yCssUCM https://www.youtube.com/watch?v=fqB4yCssUCM. This was also one of the reasons for Intel to start fighting with overclockers by locking multipliers.
- lambdaba 6y agoThanks for the correction, I remember indeed it was as you said, simply that they were capable of much higher frequencies. I didn't know that it was the case with other models, I guess I was mainly eyeing Celerons at that time because they were so cheap.
