Need help in obtaining 81MHz FSB!



New Member
my system:
500MHz Cely (PPGA)
Abit Bx6(r2.0) with Abit slot1 converter-card
128MB 100MHz RAM
I have it currently at 7.5x75 (563MHz) .. stable

In softmenuII I can only choose 75MHz FBS and then it jumps to 83MHz FSB (623MHz, unstable.. locks up)

so basically im trying to achieve the 608MHz stable speed but cant because I cant choose 81MHz FSB, so im asking is there a way to achive this bus speed with some program or something? or am i stuck at 563MHz??

Thanks in advance,
