I've got my system (Abit KT7-Raid, Duron 600) oc'd to 935 (110x8.5 w/core voltage @ 1.65). If I try to go further with FSB it locks so I was playing with the multipler and problem also. What happens if I try to go 9, 9.5, and I'm assuming higher is the system gives an error message and either looks to boot from a floppy or if it gets further into startup says the drive is bad and to replace. Have I reached the limit of my cpu, could my pencil work be faulty, increase voltage??? any thoughts appreciated.
