i have amd x2 6400 BE but why i can't change multiplier in 17X or 18X????
anybody help me??
What motherboard do you have?
my motherboard is gigabtye nvidia nforce 550.
By "Can't" you mean when you do, it doesn't boot? That's normal, there's not a lot of overclocking capability in the processor, and you'd at least need to raise the core voltage significantly first.
"unlocked" on the 6400+ BE really means "lower multipliers are unlocked", if you want higher multipliers get the 5000+ BE ...sorry, i thought the same thing when i got mine
