If you posted it, surely you can provide a link as well. ;)
Did you ever do the mod yourself?
I'd like to see a few specs on the processor, temperature drop, o/c and original speed just to compare what's possible with the iopener. =)
So far I've run a decapped K6-3/333 at a stable 400 with a bump to 2.3v and the pt6702 voltage mod, but I've yet to decap my 450+.
It will be nice to see 600 out of that one.
