Important
You can clear the CMOS RAM by shorting this jumper while the system is off.
Afterwards, open the jumper . Do not clear the CMOS RAM while the system is on
because it will damage the motherboard.
JSLOW1: Slow Mode Booting Jumper
This jumper is used for LN2 cooling solution, that provides the extreme overclocking
conditions, to boot at a stable processor frequency and to prevent the system from
crashing.
