Re: Overclock a Quad 9450
3000 MHZ is better, up the fsb a little small. you will be able to take a 3200 (fsb400) at ease without affecting the vCore. I just installed a Q9550 I have a direct mid 3.4 (8.5x400).
Re: Overclock a Quad 9450
Try this
Block port pci-e:
NB: 101
SB: 101
SPP: 200.5
Nforce chipset is usually unlinked in Auto, so no need to change anything! It's not like on an Intel chip or it will follow the fsb of Processor! However, if you encounter a problem ,you will have to manually change the frequency and timing! For that timing does not alter the 5 first line should be 7-7-7-20-2t and a 1066MHz memory!
Remove the value of self and put on the value of voltage basis:
VCore voltage: 1.2 v
CPU PLL: 1.5 v
CPU VTT: 1.2 V
Mem: according to manufacturer specification
NB: 1,3 v
SB: 1.5 v
The rest you just stay in Auto
