Hi have a K6-2/450AFX that I'd like to stick on my ASUS P5A-B. However, the chip says on the front 2.2V but the manual says 2.4V:

1Manufacturer     CPU Type           Single Plane   Dual Plane   VID0 VID1 VID2 VID3
2
3AMD (.25micron)  K6-III/400,450     ----           2.4V(Dual)   [1-2] [1-2] [2-3] [1-2]
4                 K6-2/450,475
5
6AMD (.25micron)  K6-2/266,300,333,  ----           2.2V(Dual)   [1-2] [2-3] [1-2] [1-2]
7                 350,366,380,400
8                 K6-233,266,300

I'm sure you understand my dilemma... Which settings to use?

It will work on both settings.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Thanks. It's all a bit new territory for me. I'd rather double check than blow shit up 😀

the K6-2/450AHX is a 2.4V cpu apparently, maybe the AFX just wasn't out when the manual was printed, I'd presume setting what's on the CPU should be best.

It's a bit difficult to see on this photo (actual chip), but it says "2.2V CORE/3.3V":
