I see from forums and emails that the following is happening out there:
People are taking TBreds and overclocking them. Some are seeing the initial bootup screen reporting an XP2700+. They look at something like Sandra, and it says the same thing.
Some conclude that they have a “real” 2700+ that somehow slipped through the cracks.
This is not so.
The CPUID built into these processors does not contain speed information. For that matter, it doesn’t even include the name of the processor.
In the AMD Processor Recognition datasheet, AMD simply “recommends” name strings to BIOS writers, and to insert a model number when the processor is running at certain speeds.
You run at 2700+ speed, you get a 2700+ designation in the BIOS. That’s all it is. It has nothing to do the heritage of your individual processor.
