GamePC heeft een artikel geschreven over de nieuwe cB0 stepping. Ze schrijven hoe je een Coppermine van deze stepping kan herkennen en wat er allemaal verbeterd is (er zit o.a. geen serial number meer op ):
As well as the ability to be in multi-processor environments, the new FC-PGA chips have a few internal changes as well.
1) - No More Processor Serial Number. Yes, the much-hated and controversial 96-character Intel processor serial number is now gone with the latest cB0 chips. Now all of you privacy freaks can use your Pentium III's in peace, knowing that big brother isn't watching over your shoulder.
2) - Tighter Heatsink. Even in the midst of reports of FC-PGA processors literally cracking under sub-temperature conditions, Intel is shipping a MUCH tighter heatsink/fan with their older models. This heatsink is supposed to fix problems with the metal clip not being tight enough to apply enough pressure to the processor, and now is equipped with a tighter clip to do so. While the older heatsinks were relatively easy to snap on, these new ones are quite tough, and usually require a pen or a flat head screwdriver to get the cooler on correctly. Does it cool better? Not really, but it sure does feel more secure on the processor.
3) - Various Errata Fixes. Basically, Intel fixed some minor bugs with the original FC-PGA's this spin around. While most of them don't matter to everyone, these fixes may add more stability to the chips under certain situations. Fixing bugs never hurt anyone, except maybe the bugs.
