A chip's rated clock rate is typically much lower that the max
freq it at which it can run stably -- and there is fair bit of
variation in this max freq.  A rare few 2836s can even run at
double the default frequency.  But as a side effect of
speeding it up and/or increasing internal voltage it will also
run much hotter & if you don't use a heat sink, it is likely
to fail much sooner.  They catch such use by setting an
irreversible bit inside the chip. RPF's warranty is valid only
if you left these parameters at their default value or changed
them as per their instructions (used raspi-config under linux
or use the setting n config.txt as per what raspi-config
