Sempron Socket A 2800+
2.0 Ghz core clock
256KB (exclusive) L2 cache

This doc says Vcore is 1.6V and FSB333 is the normal FSB setting.

The 2800+ number is the P.R. or performance rating. That is how
fast an equivalent Celeron would have to run, to catch up.

Your core clock is 2000MHz, your external processor clock is 166MHz.
(External clock time 2 equals FSB.) The locked multiplier is 2000/166=12.

If you set the external CPU clock in the BIOS to 166, you should
get the rated speed of 2000MHz from the core.

Sure but it's not called a 2.8GHz, just like Intel's 540 isn't 540MHz.
;p
