|"would that change your suggested safe limit"|
I'd still consider 1.50v as the safe max.
"i have " processor voltage" and " processor nb voltage" in the bios and im not sure which one to move??"
Should be obvious. Processor = CPU. Processor NB = NorthBridge chipset.
"i had a look at both. and both voltages only go up to 1.30..very confussed"
You have to reveal the "hidden" BIOS overclock settings by pressing Ctrl+F1.
"i notice jam that you haven't mentioned fsb"
That's because AMD CPUs don't use a FSB & haven't used it for many years. The memory controller is built into the CPU, not into the motherboard chipset, so the two communicate at full CPU speed.
"one other thing is it impotent to disable Cool 'n' Quiet"
If you keep it enabled, it can cause instability due to the constant changing of CPU clock speed & voltage. I'm of the opinion that it should always be disabled when overclocking, but there are guides available on how to overclock with it still enabled.
