Chip ID help

Hey guys,

What AMD chip runs at 1.4 GHZ stock?

And is it possible to run at 2.1 GHZ with stock cooling?

And what voltages would I be looking at for the CPU?

1.4GHz could be either a Thunderbird 1400, Duron 1400 or XP1600+

The Duron has 64k L2 cache where the Tbird and XP have 256k. The XP has SSE whereas the Tbird does not.

Hope this helps.

EDIT: If its a Tbird 1400, overlocking wont take you much past 1500MHz, with high voltages and high temps. Duron 1400MHz CPUs may get quite close, and XP1600+ will possibly reach it but I think Durons 1400s and XP1600s would begin to max out around 2GHz.
