My Asus P5K based PC will not boot when a PowerCore Element / PCI / PCI mkII / Unplugged is inserted. What is going on?
On some systems with Asus P5K mainboards, the system is unable to start up with a PCI based PowerCore inside.
The issue is caused by dynamic overclocking on the mainboard.
Disable dynamic overclocking in the BIOS of the mainboard itself
Upgrade to a PCI Express or FireWire based PowerCore, both of which are not affected.
