Increasing kernel hertz rate above 2499 and not having the system run backwards

I will need a reference to properly grep. The assumption is it exists in
source kernel. Lower end machines of RISC architecture need the increased
kernel hertz due to latency lag issues. Pre-preparing mentally and on other
machines.
At 2500 hertz the system goes away. There are other system control settings
yet these do not deal with lag.
Also, it is a working hypothesis that a dedicated machine for simple and
certain tasks would work better with an increased kernel rate. Tickless and
real time environments may be set up to do a comparative analysis.
Query: when was the last time anyone set up a machine with a kernel rate of
2500 or more and the machine remained stable with a patch?
