One data point:

Ever since I learned that Mavrothal operated his XO-1s in overclock 
mode, I've been running all my XO-1s at 460 MHz.  [ I run the "heavy CPU 
load" application 'Timidity' on my systems.  That extra 30 MHz 
noticeably cuts down on the number of dropped notes. ]

In three years of running some twenty XO-1s always at 460 MHz (many of 
those are powered-on 24/7), I have __NEVER__ had any one of them fail.


p.s.  I'm now having difficulty overclocking the XO-1 for 12.1.0, since 
those builds "hide" <the 'device' which contains> the script used by OFW 
to boot the XO-1 system.
