This is based on the research I did with optimizing my machine for
graphics.
I also wrote the following article:
http://www.paradoxuncreated.com/articles/Millennium/Millennium.html
It is a bit outdated now, but I will update it with current information.
The value might iterate.

Peace Be With You,
Uwaysi Bin Kareem.

+ 3956 Hz is nearly the highest timer interrupt rate supported in the
kernel.
+ Graphics workstations, and OpenGL applications may benefit from this,
