CPU Speeds and Fry's E (OT)

[George Gambill]

Logan,

Good call.  Setting the "CPU Speed" to 133/133 worked.  It now sees the CPU
as an Athlon 2200.  
Knoppix now says it is running at 1792 MHz (1.792 GHz) which is close enough
to 1.8 GHz for me.

BTW, setting the "CPU Speed" to 166/133 was not fun.  I had to do the Clear
CMOS thing.  I had to try. 

Thanks.

Yes!  Do not fault Fry's Electronics or the motherboard manufacturer.

Essentially, the motherboard supports both XP and non-XP versions of the
processor.  You may safely(1) "transform" your Athlon 1500+ processor into
an Athlon XP 2200, change the "CPU Speed" setting.  I am fairly sure
that the proper setting is "133/133" and that "166/133" is an
overclocking option, but I have a slower processor.

(1) I say safely because you really do have the XP version of the
    processor which has been rated at a certain level.  My guess is that
    a normal Athlon 1500+ may be clocked up to an Athlon XP 2200, but it
    would exceed the original processor specifications.

PS: I am not sure if the situation is similar with the P4.  I have very
little experience with them.
