I bought a 933MHz QuickSilver from a friend that I tought is 2002 version. What I found out is that is a 733MHz 2001 version overclocked. So I made a resaarch and found this site http://powermac-g4.com/g4quicksilverclockup.html

well mine is overclocked from 733 to 933, for now works ok, running Tiger and Leopard and scores from 23 - 26 points on XBench http://www.xbench.com/.

Anybody else with overclocked QuickSilver here? I can not check the heat as there are no temp. sensors on this machines.
