The majority of ASCENDS can tolerate O/C up to 710 MHZ,a few more,(748 MHZ).
Unfortunately,some do not tolerate overclocking very well,to varying degrees.
That is why some updates of CM7 are available w/overclocking to 672 MAX(aka the LAZY version of a particular update).
The typical overclock maximum setting for ASCEND CM7 ROMS is 710,w/a few versions available @ higher overclocking for those fortunate enough to have one of the handsets that can tolerate the highest stable overclocking of 729 to 748 MHZ,depending upon which update is flashed.
